Mult Btn to Mult Activities Help - Android Studio

Hey Guys,
I'm pretty new to all this and slowly learning little by little.
This is my 1st post to any android forum about developing and I've started a little project to help me learn as I go.
I'm looking to work up a basic "step by step" app. (added a quick pic to show what I'm talking about somewhat)
So it won't let me add photos yet.
I would like to have MainActivity with several buttons: Sandwich, Burger and Hotdog for this example.
Click on Sandwich and it opens up to a "Sandwich Main" which would have additional buttons: Ham, Turkey
Click on Ham and we move to "Step 1" of the how-to... Get two pieces of bread.
Next Button takes you to step #2 and so on and so on...
Just a pretty dumb and I hope simple project I can use to learn some basics.
I used the following when I was testing a single button:
public void buttonOnClick (View view) {
Button button = (Button) view;
startActivity (new Intent(getApplicationContext(), Main2Activity.class));
}
This was straight forward easy way to get a single button to move to a new activity.
Now when I attempted to add a second button to the mix, it didn't work.
If there is a way to easily add multiple button to the above, let me know please... I found this way to be easiest for me to get so far.
So next I tried to go about it at a different angle:
activity_main.xml:
<RelativeLayout xmlns:android=".... (WON'T LET ME TYPE LINKS)
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="104dp"
android:layout_marginTop="20dp"
android:text="Button1" />
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/button1"
android:layout_below="@+id/button1"
android:layout_marginTop="34dp"
android:text="Button2" />
MainActivity.java:
public class MainActivity extends Activity implements OnClickListener {
Button b1,b2,
@override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b1 = (Button)findViewById( R.id.button1);
b2 = (Button)findViewById(R.id.button2);
b1.setOnClickListener(this);
b2.setOnClickListener(this);
}
@override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button1:
Toast.makeText(getApplicationContext(), "button1 is working", 3000).show();
break;
case R.id.button2:
Toast.makeText(getApplicationContext(), "button2 is working", 3000).show();
break;
}
}
}
By doing the above I end up with the activity2 button clicking to activity3 first rather than activity2.
Activity3 button clicked correctly to activity3.
Another quick pic below to show what is going on... (whoops, won't let me post pics until I have 10 posts)
*MainActivity (BtnActivity2) and (BtnActivity3)
--- BtnActivity2 > opens Activity3 - (press phone back button) > Activity2 - (press back button again) > MainActivity
--- BtnActivity3 > opens Activity3 - (press phone back button) > Main Activity *** WORKING CORRECTLY ****
Any help would be appreciated!

I know that no one has posted up any replies but I thought I would update on my progress.
Does anyone see any possible issues I will have by going this route?
I've gotten each button to open each desired activities now by using the following:
AndroidManifest.xml
<?xml version-“1.0” encoding=”utf-8”?>
<manifest xmlns:android=”……..”

import android.content.Intent;
public class MainActivity extends Activity implements OnClickListener {
Button button, button2;
@override
protected void onCreate(Bundle savedInstantState) {
super.onCreate(savedInstantState);
setContentView (R.layout.activity_main);
button=(Button) findViewById(R.id.button);
button2=(Button) findViewById(R.id.button2);
}
@override
public void onClick(View view) {
switch (view.getId()){
case R.id.button:
startActivity(new Intent(getApplicationContext(), Main2Activity.class));
break;
case R.id.button:
startActivity(new Intent(getApplicationContext(), Main2Activity.class));
break;
}
}
}

Yes you are on the right path... The key is to add each Activity (view) to your Manifest (You already did), if not when you are traversing to separate Activities by button click it wont work. If you run into any other issues let me know, ill be glad to help.

Yeah, I think I've pretty much gotten the hang of the methods used when implementing buttons within the activities.
I'm pretty new at this and try to learn as I go and when I get time to set down and mess with it all.
Right now I'm attempting to learn more and more about using fragments and when it is best to do so.

Sounds good. We are in the same boat; Fragments + Material Design is the new trend, I try to learn as much as I can and use them as much as I can. Good luck!

[TUTORIAL]Xposed module devlopment

Iv'e recently started a blog on Xposed Module development. It goes through the basics for a beginner and explains in as much detail as possible. You can find it here
http://xposedtutorial.blogspot.co.uk/p/tutorial-1-setting-up.html
Edit: I've now decided to keep the tutorial on XDA. I might also keep a copy on the blog, not sure yet
P.S: A lot of this tutorial is based on the original development tutorial which can be found here, credits to rovo89
Tutorial 1 - Setting up
There are a few requirements for making an Xposed Module.
*Eclipse, or Java IDE of your choice, with Android SDK and devlopment enviornment set up. I'm not going to cover that in this tutorial
*Knowledge of Java programming language
*An android phone which supports Xposed, with Xposed installed and working for testing on
*Some knowledge of Android development
*Time
*An idea of course
For the purpose of this tutorial, we will be creating two modules (using two different features of the xposed bridge). The first will replace the clock in the status bar with a smiley face. The second will change the height of the navigation bar. I will be using Eclipse or Android Studio in this tutorial.
Eclipse
NEW: this tool will setup the project for you! http://forum.xda-developers.com/showthread.php?t=2712825
Firstly you must set up an Android project as normal. For the target API, use the latest available. Name the project Smiley Clock, and choose a package name.
We won't need an Activity for this module, so don't create one
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Android Studio
Firstly you must set up an Android project as normal. For the target API, use the latest available. Name the project Smiley Clock, and choose a package name.
We won't need an Activity for this module, so don't create one
OK, that's the project created. Now we need to make Xposed recognize this as a module. Add the following meta tags to your Android Manifest, within the Application tag
Code:
<meta-data
android:name="xposedmodule"
android:value="true" />
<meta-data
android:name="xposedminversion"
android:value="30" />
<meta-data
android:name="xposeddescription"
android:value="Add a smiley face" />
At this point you can run the application on your test device. It should show up in the Xposed Installer app as a module. Check the box to enable your module and reboot your device. Of course, the module won't do anything yet!
A good idea at this point would be to add a new filter to your logcat to track error messages from Xposed.
Studio: Go on Android Monitor (along bottom). Make a new filter and filter by tag name. The tag is "xposed"
Eclipse:
Add a filter named "Xposed" and filter by the tag name "Xposed"
(picture is for Eclipse)
You will now see messages from the Xposed Framework
There will be an error for your module about xposed_init file, don't worry, getting to that!
Make a new package (same as package name we used when making the Android Project) and within that package make a class. Call it anything, I'll call mine Main.
Secondly add the XposedBridge API jar. This can be found on this thread on XDA. Add the jar to the root directory of the project, NOT the lib directory.
Eclipse: Right click - build path - add to build path. Do not export it in the Order and Export tab.
Studio: Right click, add as library. Then go in gradle files and find build.gradle for the app module. Find the dependency which looks something like this
compile files('src/main/java/com/hamzahrmalik/xposedtutorial/XposedBridgeApi-54.jar')
and change the "compile" to "provided" so it is like
provided files('src/main/java/com/hamzahrmalik/xposedtutorial/XposedBridgeApi-54.jar')
Now create a file in the assets directory called xposed_init.
Studio users:
First you will need to make the assets directory. I think the easiest way is to first switch to "project files" view at the top of the navigation pane as shown below. Then create a folder inside src/main called assets. Then place the xposed_init in the assets folder.
Inside this file, type:
packagename.classname
where packname is the name of your package and class name is the name of your class. So in my case I will type
com.hamzah.smileyclock.Main
This tells Xposed where to look for the code for the module. You file tree should now look like this
Now the project is set up. In the next tutorial, we will look at how Xposed works, this will help you understand how to make modules.
Tutorial 2 - Brief introduction to how Xposed works
This tutorial is not really a true tutorial (gasp!). It will outline some basic features of Xposed which will help you understand future tutorials.
Xposed allows a developer to access and modify the code for system applications. For example, one useful feature is the "find and hook" feature. This allows a developer to find a method inside another application and add their own code after it. So you could find the method in the Android source code that alerts the user when the wrong pattern is entered, and then instruct the system to hook onto that method and edit the alert to say something else. Another thing that Xposed allows us to do is replace resources. This includes Strings dimensions, drawables and much more. So we could edit the dimension of the navigation bar height (which we will in later tutorials) by replacing the resource which tells it what height to be.
The next tutorial, we will start exploring the Android code and see what methods to hook to replace the clock with a smiley face!
Tutorial 3 - Exploring the target and modifying it
Ok so at this point, you should have an Xposed mod thatdoes nothing. The next step is to work out exactly what we want it to do! We want it to edit the clock, by hooking the method (read the last tutorial for more informtion on this). So the first step is to find that method.
So visit http://grepcode.com/project/repository.grepcode.com/java/ext/com.google.android/android/ in your browser to view Android's source code. If (in Android 4+) you browse to com.android.systemui.statusbar.policy.Clock.java
you will find the class that controls the clock. In here, there is a handy method called updateClock() which ppears to be controlling what gets written to the TextView in the statusbar (this whole class extends TextView). Now if you know how to make Android apps (which you should) you will be familiar with TextView. We can manipulate this TextView by changing colour, text, font, size etc, as you could with a TextView in a normal Android app.
Of course this was easy, but depending on exactly what you want your module to do, you may have to hook many methods. If you've ever modded APK's, you'll know what i mean
This was another short tutorial, in the next one we will start coding the module
Tutorial 4 - The Code
In this tutorial we can finally get to some code. Exciting right?
OK so we now have the following information
*We can hook methods using Xposed
*There happens to be a method which writes text to the clock
*We can hook this method to edit the text
So first of all, fire up your eclipse workspace and have you Xposed class implement IXposedHookLoadPackage
Then add unimplemented methods.
Your class should now look like:
Code:
package com.hamzah.smileyclock;
import de.robv.android.xposed.IXposedHookLoadPackage;
import de.robv.android.xposed.callbacks.XC_LoadPackage.LoadPackageParam;
public class Main implements IXposedHookLoadPackage {
@Override
public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable {
}
}
The method that we are overriding gets called every time the user or system opens an app. We can use the parameter of the method to check when systemui gets loaded, then hook into it and modify the clock. Easy right?
Add this inside your method
Code:
if (!lpparam.packageName.equals("com.android.systemui"))//check if the package being loaded is systemUI
return;
//All code here is only called if it is indeed SystemUI
So now we need our hook, add this code after the return:
Code:
findAndHookMethod("com.android.systemui.statusbar.policy.Clock", lpparam.classLoader, "updateClock", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
}
});
NOTE: this will only work because updateClock doesn't need any parameters. If the method you want to hook does, see tutorial 9
You must also add the following imports statements
Code:
import de.robv.android.xposed.IXposedHookLoadPackage;
import de.robv.android.xposed.XC_MethodHook;
import de.robv.android.xposed.callbacks.XC_LoadPackage.LoadPackageParam;
import static de.robv.android.xposed.XposedHelpers.findAndHookMethod;
Explanation: The findAndHookMethod is hooking onto com.android.systemui.statusbar.policy.Clock
The afterHookedMethod allows us to add our own code after the system method is executed, so in this case, the code to add a smiley face will go here. The MethodHookParam allows us to modify the TextView of the method we are hooking. So we need to get hold of that TextView, add this code
Code:
TextView tv = (TextView) param.thisObject;
This is the TextView containing the clock, whatever we do with this TextView at this point, will happen to the TextView in the statusbar, So now simply add
Code:
tv.setText(":)");
This will replace the clock with a smiley face. Alternatively, use
Code:
tv.appendText(":)");
to keep the time and add the smiley after it
Now deploy the app to your test device, and reboot. You should see a smiley face in place of the clock!
Full Code
Code:
package com.hamzah.smileyclock;
import static de.robv.android.xposed.XposedHelpers.findAndHookMethod;
import android.widget.TextView;
import de.robv.android.xposed.IXposedHookLoadPackage;
import de.robv.android.xposed.XC_MethodHook;
import de.robv.android.xposed.callbacks.XC_LoadPackage.LoadPackageParam;
public class Main implements IXposedHookLoadPackage {
@Override
public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable {
if (!lpparam.packageName.equals("com.android.systemui"))
return;
findAndHookMethod("com.android.systemui.statusbar.policy.Clock", lpparam.classLoader, "updateClock", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
TextView tv = (TextView) param.thisObject;
tv.setText(":)");
}
});
}
}
That's it for SmileyClock, in the next tutorial, we will look at another feature of Xposed, that is, replacing resources, and will enable/disable the screen wake up on unplug and also edit the height of the system navigation bar.
Tutorial 5 - Replacing Resources
Xposed allows us to replace resources such as String, int, boolean, dimen, or even drawables. In this tutorial we will enable/disable screen wake-up on unplug and in the next one, replace the dimen of navigation bar height and width to make it half size. Simple resources like int and String can be replaced by passing the new value as a parameter but more complex ones like drawable and dimen must be referenced from your own resources. Don't worry, I'll explain it all!
First, we will replace a boolean which tells the system whether or not to wake the screen on unplug. There is a boolean in the framework-res.apk (found in /system/framework) which tells the system this information. We can used Xposed to edit this value, without touching the APK. My phone's default is false so I'm going to make it true, if yours is already true, make it false to make it more noticeable. In a future tutorial, when we learn saving preferences, we will add the ability for the user to set the value. For now, it will be hard coded.
Firstly set up a new project as in tutorial 1. Call it anything. Again, no activity or icon required, though you might want an icon anyway.
Have your class implement IXposedHookZygoteInit
and add unimplemented methods. This is called before anything else and we will use it for replacing our resource.
Add this code inside the initZygote method
Code:
XResources.setSystemWideReplacement("android", "bool", "config_unplugTurnsOnScreen", false);
android is the package name of framework-res, bool is the type of resource (boolean) "config_unplugTurnsOnScreen" is the variable we are replacing and false is the new value.
Now when you run this module, enable and reboot, you should find that if you plug in a charger, turn off the screen, and unplug it, nothing will happen. If you were to change it to TRUE instead of FALSE, when you unplugged, it would wake the screen.
In the text tutorial, we will replace the navigation bar height
Tutorial 6 - Complex Resources
In this tutorial we will change the height of the navigation bar to 36dp, normal is 48dp. Much is the same as last time, but there are a few differences. Once again, set up a new project. Have your module class implement IXposedHookZygoteInit once again. Also implement IXposedHookInitPackageResources
Add the unimplemented methods.
Make a new variable inside the initZygote method:
Code:
String MODULE_PATH = startupParam.modulePath;
In the handleInitPackageResources method, add
Code:
if (!resparam.packageName.equals("android"))
return;
Now we know we are in the right package
Add:
Code:
XModuleResources modRes = XModuleResources.createInstance(MODULE_PATH, resparam.res);
Use CTRL-SHIFT-O in Eclipse to import the necessary packages.
Next we need a dimen resource to forward as the height of the navigation bar. Make a new XML files inside /values called dimens.xml. Add this inside it
Code:
36dp
Now all that's left is to forward this to be used. Add this code inside handleInitPackageResources
Code:
XResources.setSystemWideReplacement("android", "dimen", "navigation_bar_height", modRes.fwd(R.dimen.navigationbarSize));
The first 3 parameters are the same as the ones in tutorial 5. The last one has the same function as in the las tutorial, but rather than passing a variable, we are forwarding a resource. This could also be done with drawables, I once made a module to replace all buttons on the navigation bar with the ones found on Xperia ROM's.
At this point, when you deploy the module, enable it and reboot, your navigation bar should be noticeably smaller.
In the next tutorial we will look at creating and user interfaces and saving data in ways that both interface and module can read and write to. We will be using the mod we made in tutorial 4, and allow the user to define text rather than have a smiley face.
Tutorial 7 - User Interfaces and Preferences
Open up the SmileyClock we made in Tutorial 4. We did not make an Activity so make one now, File>New>Android Activity. Make sure you make it a Launcher Activity. We need to widgets in our UI, a textbox and an Apply button. I'm not going to cover making these, just make sure you have a method called when the button is pressed. Make the EditText id "input" so it will be easier to follow the tutorial because that is what i am making mine.
When the apply button is pressed in my case this method is called
Code:
public void apply(){
EditText et = (EditText) findViewById(R.id.input);
String input = et.getText().toString();
}
So now I have the user input as a String, I need to save it. Use Android SharedPreferences for this,
Code:
SharedPreferences pref = getSharedPreferences("user_settings", MODE_WORLD_READABLE);
The mode world readable is crucial to allow the Xposed Module to read it, otherwise you will get permission denied. Now get the Editor and save this string as "user_text",
Code:
Editor editor = pref.edit();
editor.putString("user_text", input);
Now it is saved, we need the Xposed Module to read it. Switch back to the class containing the Xposed Module, the one we made in tutorial 4. Find this line:
Code:
tv.setText(":)");
Instead, replace it with this
Code:
XSharedPreferences pref = new XSharedPreferences("com.hamzah.smileyclock", "user_settings");
//Gets the shared preference
String text = pref.getString("user_text", "");
//reads the value which is saves, using nothing as default value to use if nothing is saved
tv.setText(text);
//sets the text to saved value
When you deploy this and set some text, that text should then appear in the status bar after the clock. Note that when you save this value, it will not change in the statusbar until you restart SystemUI. It might change when time changes, not sure.
In the next tutorial we will cover modifying layouts
Tutorial 8 - Modifying Layouts
Xposed lets us modify layouts in other apps. In this tutorial, we will modify the navigation bar with various tweaks. Firstly we will make the background blue. So make a new Xposed Project and have your module class implement IXposedHookInitPackageResources. This gives is a parameter that can be used for modifying layouts. Add the unimplemented method and add this code inside the method
Code:
resparam.res.hookLayout("com.android.systemui", "layout", "navigation_bar", new XC_LayoutInflated() {
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable {
}
});
com.android.systemui is the package name for the app containing the navigation bar View, layout is the type of resource, navigation_bar is the View name as defined in /res/layout (of SystemUI.apk). Now we need to get a View object for the navigation bar. Add this code inside the overriden method
Code:
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable {
View navbar = (View) liparam.view.findViewById(
liparam.res.getIdentifier("nav_buttons", "id", "com.android.systemui"));
}
We have gotten the view using the findViewById method, and passing in the ids. We know the id is "nav_buttons" because if we look at /res/layouts/navigation_bar.xml in SystemUI.apk, we see this
Code:
<?xml version="1.0" encoding="utf-8"?>

Now we can call methods we could normally call on a View object. Add
Code:
navbar.setBackgroundColor(Color.BLUE);
When you run this on your phone, your navigation bar will be blue. Now of course you can also call other methods, such as adding in new TextView's or whatever. If you were to inspect the code more closely, you would find there are also ids called "home" "back" and "recent_apps". You could use these to mess around with the buttons, though I cannot imagine what!
Tutorial 9 - Methods with parameters
In an earlier tutorial, we covered hooking methods. But what if a method wants a parameter too?
Say if i want to hook onCreate(Bundle savedInstances) in com.android.settings
If i hook it using
Code:
findAndHookMethod("com.android.settings.Settings", lpparam.classLoader, "onCreate", new XC_MethodHook() {
});
It will throw a methodNotFound error. So we need to specify the parameters. The method wants a Bundle object. So add Bundle.class as a parameter
Code:
findAndHookMethod("com.android.settings.Settings", lpparam.classLoader, "onCreate", [B]Bundle.class[/B], new XC_MethodHook() {
});
Now lets pretend Bundle.class isnt in the SDK and is a system class so cant be referenced. I would use a String instead:
"android.os.Bundle"
Code:
findAndHookMethod("com.android.settings.Settings", lpparam.classLoader, "onCreate", [B]"android.os.Bundle"[/B], new XC_MethodHook() {
});

Nice Tutorials, but this what you've posted until now is already published by a lot of peoples (also on the offical GitHub-Page).
It would be awesome if you show some other (non-public) Tutorials, e.g how to make a PreferenceMenu and use it

[Q] WebView - Please help

Hello. I want to make webview app, but with buttons like in the image that I have created. Back - Refresh - Forvard.
So maybe someone can help, I'm green with it...
Hi there,
So first thing you need to do is grant INTERNET permission to your app by edditing AndroidManifest.xml
For example (I've made all my additions in bold),
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.application.my.webviewtest" >
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
[B]<uses-permission android:name="android.permission.INTERNET" />[/B]
</manifest>
Then you need to edit your View so that you have a WebView widget and some buttons, i'm just showing a back and forward button here, so in my activity_main.xml I have,
Code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">
[B] <LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true">
<WebView
android:layout_width="match_parent"
android:layout_height="400dp"
android:id="@+id/myWebView"/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="64dp">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="<"
android:id="@+id/backButton"
android:onClick="OnBackButtonClick"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=">"
android:id="@+id/forwardButton"
android:onClick="OnForwardButtonClick"/>
</LinearLayout>
</LinearLayout>[/B]
</RelativeLayout>
You'll notice I've put it in a vertical linearlayout, and then inside of that a horizontal linearlayout to host the buttons, now for the code in MainActivity.java,
Code:
package com.application.my.webviewtest;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
[B]import android.view.View;
import android.webkit.WebView;
import android.webkit.WebViewClient;[/B]
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
[B] WebView webview = (WebView) this.findViewById(R.id.myWebView);
webview.setWebViewClient(new WebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://www.google.co.uk");[/B]
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
[B] public void OnBackButtonClick(View view) {
WebView webview = (WebView) this.findViewById(R.id.myWebView);
webview.goBack();
}
public void OnForwardButtonClick(View view) {
WebView webview = (WebView) this.findViewById(R.id.myWebView);
webview.goForward();
}[/B]
}
I've zipped up the app folder of my AndroidStudio project for you

Push button secret code help

I am have been working on this app for a few weeks now. I have never done any coding in my life, until I started this app. I have a few secret codes/dial codes that I use often, but i forget what code to use when sometimes, so I wanted to make an app that would make it as simple as clicking a button, and the app would send the code for me.
I have all my buttons, and I have them programmed. I gave the permissions that I think it needs, but when I run the app on my phone I get nothing. In Android Studio, I can read this,
"W/BroadcastQueue: Permission Denial: broadcasting Intent { act=android.provider.Telephony.SECRET_CODE dat=android_secret_code://XXXXXX flg=0x10 } from com.myapp.appname (pid=7540, uid=10128) requires android.permission.CONTROL_INCALL_EXPERIENCE due to receiver com.google.android.apps.tycho/.receivers.DialerCodeReceiver"
for permissions I have:
AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.CONTROL_INCALL_EXPERIENCE" />
MainActivity.java:
import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
@override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button)findViewById(R.id.Button);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
String secretCode1 = "xxxxx";
String action = "android.provider.Telephony.SECRET_CODE";
Uri uri = Uri.parse("android_secret_code://" + xxxxx);
Intent button1 = new Intent(action, uri);
sendBroadcast(button1);
}
});
Activity_main.xml - Textview
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Button"
android:id="@+id/Button"
android:layout_gravity="center_horizontal"
androidnClick="onbuttonclick" />
Please, let me know what I did wrong, or if you need more information to fix it.

I did also try the dial intent, but when the button was pressed it would only dial * and not the #*#code#*#*
I hate to bump but I have had no response yet.
Have you resolved this problem? I'm running into a similar issue and am curious if you were able to resolve this.
You've written -
<uses-permission android:name="android.permission.CONTROL_INCALL_EX PERIENCE" />
There's a space between EX and PERIENCE..
I'm sure that's causing the error..

need help buttons

hi,
im totally new to this, been playing around for like 2 days
i want to put buttons on my app, i add the buttons, place them correctly in android studio but when i build apk and install it on my phone
the buttons disappear only one remain top left corner...
how do i place a button and make its position stay?
is there something im missing with the screen resolution or something?
if anyone could give me hint... would be much appreciated
thanks
nate
Could you post your layout xml file so we can see how you declared these buttons?
activity main.xml:
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout xmlns:android="****"
xmlns:app="****"
xmlns:tools="****"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="org.thepiratebay.keven.MainActivity"
android:background="@drawable/background">
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_x="51dp"
android:layout_y="47dp"
androidnClick="sound1"
android:text="bonnefete1" />
</AbsoluteLayout>
mainactivity.java:
package org.thepiratebay.keven;
import android.media.MediaPlayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
MediaPlayer sound1;
@override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sound1 = MediaPlayer.create(this, R.raw.a1toutunmot);
}
public void sound1(View view) {
sound1.start();
}
}
i found on google someone saying
To play a sound try this method:
MediaPlayer mp = MediaPlayer.create(YourActivity.this, R.raw.mysound);
mp.setOnCompletionListener(new OnCompletionListener() {
@override
public void onCompletion(MediaPlayer mp) {
// TODO Auto-generated method stub
mp.release();
}
});
mp.start();
This is the best way I found to play a sound in Android. Hope it helps!
not sure where i place this code?
thanks for help
nate
i just want to release mediaplayer when the sound is finished playing
