Hi,
I have a problem with empty layout. Namely I just want to make a button (button2) to open another layout with image and when I click on the button show up empty layout.
MainActivity.java:
Code:
public class MainActivity extends AppCompatActivity {
Button button1;
Button button2;
Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context = getApplicationContext();
button1 = (Button)findViewById(R.id.button1);
button1.setText("sprawdz czy dziala");
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Toast.makeText(context, "Przycisk działa!", Toast.LENGTH_LONG).show();
}
});
button2 = (Button) findViewById(R.id.button2);
button2.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
Intent myIntent = new Intent(MainActivity.this, NewActivity.class);
startActivity(myIntent);
}
});
}
}
class NewActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.frame);
}
}

On the second layout (frame) I have a image. I just want to open this layout with image when I click on the button (button2).
Promblem: When I press on the button show up layout without image.
frame.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:srcCompat="@drawable/hol_airplane"
android:id="@+id/imageView21" />
</RelativeLayout>

So.. I stayed up all night and finally got XSharedPreferences to work with my module. But today when I tried to add other elements such as a Navigation Drawer, and have the preference page only show when tapped, it stopped working.
This is the MainActivity code that has been working just fine.
Working:
Code:
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState == null)
getFragmentManager().beginTransaction().replace(android.R.id.content, new PrefsFragment()).commit();
}
public static class PrefsFragment extends PreferenceFragment {
@SuppressWarnings("deprecation")
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getPreferenceManager().setSharedPreferencesMode(MODE_WORLD_READABLE);
addPreferencesFromResource(R.xml.prefs);
}
}
}
Below is the code where it stopped working. I tried back tracking and only with the code above does it work.
Not working:
Code:
public class MainActivity extends AppCompatActivity implements NavigationDrawerCallbacks {

Well.. seems like moving the code that worked to its own activity and the following to the mainactivities oncreate has done the trick.
Code:
pref = getSharedPreferences(getPackageName() + "_preferences", MODE_WORLD_READABLE);
I am unable to get XSharedPreferences to work and the standard shared preferences work perfectly. I create a shared preferences file elsewhere in the application. The file is in the shared_pref folder and I can read the file which is perfectly OK.
However, I cannot make the XSharedPreferences work, I. e. I have the opposite problem.
Therefore, can I ask you to provide the code or a guidance how to make the XSharedPreferences work, so I can read the file inside of the Xposed module? In case you do not want to publish anything in this topic, can you please, send a message?
Hi. Is there a way for a tabhost to display content of it's tabs above insted below like in all examples i found on net?
just use buttons and framelayout as fragment container
change fragment inside container when user click button
Thank you. And just another question, can I somehow display name of tab which is opened in action bar so I don't need to create new LinearLayout bellow it?
NVM. Found it: setTitle()
Is it possible to use Views (Button) from one fragment in another?
I need to have button in my other fragment. When I press on it so it returns to some other or opens new fragment. But I can't make OnClickListener for button that will be initialized later and it isn't on my Main_Layout. How can I solve this so I can use that button to move between my tabs or open new frames?
Code:
onCreate(){
home.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
setFragment(new HomeFragment());
setTitle("Home");
}
});
signin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
setFragment(new SigninFragment());
setTitle("Sign In");
}
});
}
protected void setFragment(Fragment fragment) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction =
fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.frameLayout, fragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
public class HomeFragment extends Fragment {
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState)
{
return inflater.inflate(R.layout.home_fragment,container,false);
}
}
My app crashes on start. Anyone see the problem?
Code:
public class Fragment3 extends Fragment implements View.OnClickListener {
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState)
{
View myView = inflater.inflate(R.layout.fragment3_layout, container, false);
final Button b12=(Button) myView.findViewById(R.id.button35);
b12.setOnClickListener(this);
return myView;
}

Hello,
this time iI'm working on an app where you can write something and click to the save button.
The important thing is that if you click on the save button than you have a new created textview in the other activity
the class where you write a notice and click on save button
Code:
public class NewNoticeActivity extends AppCompatActivity {
Button saveButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_notice);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
public void onCancelClick(View view){
Intent intentNew = new Intent(view.getContext(), NewActivity.class);
startActivity(intentNew);
}
public void onSaveClick(View view){
saveButton = (Button) findViewById(R.id.saveButton);
saveButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
EditText editText = (EditText) findViewById(R.id.editText);
String notice= editText.getText().toString();
Intent intentSaveNotice = new Intent(view.getContext(), YourNoticesActivity.class);
intentSaveNotice .putExtra("my notice", notice);
startActivity(intentSaveNotice );
}
});
}
}
so what i tried to do is that you first have nothing in the YourNoticesActivity
and after clicking on save you have 1 more notice and so on
i hope you could understand me
