Having Trouble with SharedPreferences

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 {
/**
* Fragment managing the behaviors, interactions and presentation of the navigation drawer.
*/
private NavigationDrawerFragment mNavigationDrawerFragment;
private Toolbar mToolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
setSupportActionBar(mToolbar);
mNavigationDrawerFragment = (NavigationDrawerFragment)
getFragmentManager().findFragmentById(R.id.fragment_drawer);
// Set up the drawer.
mNavigationDrawerFragment.setup(R.id.fragment_drawer, (DrawerLayout) findViewById(R.id.drawer), mToolbar);
// populate the navigation drawer
mNavigationDrawerFragment.setUserData("John Doe", "[email protected]", BitmapFactory.decodeResource(getResources(), R.drawable.avatar));
}
@Override
public void onNavigationDrawerItemSelected(int position) {
Fragment fragment;
switch (position) {

Click to expand...
Click to collapse
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?

Onclock property

Can set an oncick listener via this property or not?
I have tried this: androidnClick="@string/str_onclick_searchbt"
where str_onclick_searchbt = "onClickSearch" corresponding to a function onClickSearch(View view).
But it does not seem to be working - my app seems to crash.
If you can't do this then what is the onclick property for?

Change to anonymous onclick listener
I have changed my code to implement the onclick listener on onCreate rather than through the onclick button property.
But still my app seems to crash due to the highlighted code. If I comment it out my app starts up as expected but does not respond to button clicks.
So what I am doing wrong?
Code:
public class HexapodControls extends Activity
{
BluetoothAdapter m_BTAdapter;
BroadcastReceiver m_BTReceiver;
ArrayAdapter<String> m_BTArrayAdapter;
@Override
protected void onCreate(Bundle savedInstanceState)
{
final Button buttonConnectBT = (Button)findViewById(id.button_connectbt);
final Button buttonDisconnectBT = (Button)findViewById(id.button_disconnectbt);
final Button buttonSearchBT = (Button)findViewById(id.button_searchbt);
final Button spinnerBT = (Button)findViewById(id.spinner_bluetooth);
final AlertDialog alertDialog;
alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("In onCreate(...)");
alertDialog.setMessage("Search button clicked...");
alertDialog.setButton(DialogInterface.BUTTON_POSITIVE, "OK", (DialogInterface.OnClickListener) null);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hexapod_controls);
getBluetoothDevices();
[B]buttonSearchBT.setOnClickListener(
new View.OnClickListener() {
@Override
public void onClick(View view) {
spinnerBT.setEnabled(false);
buttonConnectBT.setEnabled(false);
buttonDisconnectBT.setEnabled(false);
alertDialog.show();
if (m_BTAdapter.isDiscovering())
m_BTAdapter.cancelDiscovery();
m_BTAdapter.startDiscovery();
}
});[/B]
/*
buttonConnectBT.setOnClickListener(
new View.OnClickListener() {
@Override
public void onClick(View view)
{
buttonConnectBT.setEnabled(false);
buttonDisconnectBT.setEnabled(true);
}
});
buttonDisconnectBT.setOnClickListener(
new View.OnClickListener()
{
@Override
public void onClick(View view)
{
buttonConnectBT.setEnabled(true);
buttonDisconnectBT.setEnabled(false);
}
});
*/

Drawer navigation with navigation toggle

Hi. Can you link to some simple tutorial or other help for Drawer navigation with navigation toggle. I plan to use lot of fragments.

I have implemented Navigation drawer. But when I open fragment and add back arrow when fragment is open instead "navigation hamburger icon", it doesn't go back to starting page but instead open drawer again. Here is the code I mostly got from tutorial,but want to move on:
MainActivity:
Code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView=(ListView)findViewById(R.id.listView);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
toolbar=(Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
//getSupportActionBar().setDisplayShowHomeEnabled(true);
final NavigationDrawerFragment drawerFragment=(NavigationDrawerFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
drawerFragment.setUp(R.id.fragment_navigation_drawer,(DrawerLayout)findViewById(R.id.drawer_layout),toolbar);
adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,sports);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mDrawerLayout.closeDrawers();
}
});
}
protected void setFragment(Fragment fragment) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction =
fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.drawer_layout, fragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
private void selectItem(int position)
{
switch (position) {
case 0:
setFragment(new SoccerFragment());
break;
}
}
and for navigation fragment:
Code:
public NavigationDrawerFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mUserLearnedDrawer=Boolean.valueOf(readFromPreferences(getActivity(), KEY_USER_LEARNED_DRAWER, "false"));
if (savedInstanceState!=null)
{
mFromSavedInstanceState=true;
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_navigation_drawer, container, false);
}
public void setUp(int fragmentId,DrawerLayout drawerLayout,Toolbar toolbar) {
//containerView=getActivity().findViewById(fragmentId);
mDrawerLayout=drawerLayout;
mDrawerToggle=new ActionBarDrawerToggle(getActivity(),drawerLayout,toolbar,R.string.drawer_open,R.string.drawer_close)
{
@Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
if (!mUserLearnedDrawer)
{
mUserLearnedDrawer=true;
saveToPreferences(getActivity(), KEY_USER_LEARNED_DRAWER,mUserLearnedDrawer+"");
}
getActivity().invalidateOptionsMenu();
}
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
getActivity().invalidateOptionsMenu();
}
};
//if (mUserLearnedDrawer && mFromSavedInstanceState)
//{
// mDrawerLayout.openDrawer(containerView);
//}
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerLayout.post(new Runnable() {
@Override
public void run() {
mDrawerToggle.syncState();
}
});
}
public static void saveToPreferences(Context context,String preferenceName,String preferenceValue)
{
SharedPreferences sharedPreferences=context.getSharedPreferences(PREF_FILE_NAME,Context.MODE_PRIVATE);
SharedPreferences.Editor editor=sharedPreferences.edit();
editor.putString(preferenceName, preferenceValue);
editor.apply(); //or commit()
}
public static String readFromPreferences(Context context,String preferenceName,String defaultValue)
{
SharedPreferences sharedPreferences=context.getSharedPreferences(PREF_FILE_NAME, Context.MODE_PRIVATE);
return sharedPreferences.getString(preferenceName,defaultValue);
}
}

Take input from edittext, click to save and create new textview

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
