Navigation Drawer does not open when I click App name from ActionBar

Navigation Drawer does not open when I click App name from ActionBar - android

I have implemented the Navigation Drawer into my new app. But I cannot get the App name from ActionBar to toggle the Navigation Drawer. However, when I drag the navigation drawer, the ActionBar respond to this action by changing to an arrow.
Here is my code:
services_activity_main.xml
<LinearLayout
android:orientation="vertical"
android:id="#+id/container_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout

android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>
<LinearLayout
android:id="#+id/contents_layout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:layout_marginEnd="10dp">
</LinearLayout>
<LinearLayout
android:id="#+id/navigation_bar_layout"

You shouldn't handle your navigation drawer from fragment.
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
drawerToggle = new ActionBarDrawerToggle(getActivity(), drawerLayout, R.string.app_name, R.string.app_name) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
Log.i(TAG, "Drawer Closed!");
if (!isAdded()) {
return;
}
// activity.invalidateOptionsMenu();
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
Log.i(TAG, "Drawer Opened!");
if (!isAdded()) {
return;
}
if( ! userLearnedDrawer) {
userLearnedDrawer = true;
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(activity);
sharedPreferences.edit().putBoolean(PREF_USER_LEARNED_DRAWER, true).apply();
}
// activity.invalidateOptionsMenu();
}
};
if( ! userLearnedDrawer && ! fromSavedInstance) {
drawerLayout.openDrawer(navigationDrawerLayout);
}
drawerLayout.post(new Runnable() {
#Override
public void run() {
drawerToggle.syncState();
}
});
drawerLayout.setDrawerListener(drawerToggle);
} catch(ClassCastException e) {
throw new ClassCastException(activity.getClass() + " must implements NavigationDrawerCallbacks interface.");
}
}
private ActionBar getActionBar() {
return getActivity().getActionBar();
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt(STATE_SELECTED_POSITION, selectedPosition);
}
#Override
public void onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(drawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
drawerToggle.onConfigurationChanged(newConfig);
}a
Shift above code from fragment to your MAinActivity.java

Make sure you have everything on your drawerToggle like follows
mDrawerToggle = new ActionBarDrawerToggle(
getActivity(), /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */
R.string.navigation_drawer_open, /* "open drawer" description for accessibility */
R.string.navigation_drawer_close /* "close drawer" description for accessibility */
) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
if (!isAdded()) {
return;
}
getActivity().invalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
if (!isAdded()) {
return;
}
if (!mUserLearnedDrawer) {
// The user manually opened the drawer; store this flag to prevent auto-showing
// the navigation drawer automatically in the future.
mUserLearnedDrawer = true;
SharedPreferences sp = PreferenceManager
.getDefaultSharedPreferences(getActivity());
sp.edit().putBoolean(PREF_USER_LEARNED_DRAWER, true).apply();
}
getActivity().invalidateOptionsMenu(); // calls onPrepareOptionsMenu()
}
};

Android NavigationDrawer onAttach is deprecated

I'm using the Navigation Drawer, recently I changed build.gradle to compile the app with API 23.
I noticed that the method onAttach has been deprecated. I found several solutions in this forum, Android Fragment onAttach() deprecated but none of them work, have you other solutions? Thank you

Not sure what was wrong with the solution that you found. but onAttach should accept a Context. An Activity is a Context so the following should work.
#Override
public void onAttach(Context context) {
super.onAttach(context);
try {
mCallbacks = (NavigationDrawerCallbacks) context;
} catch (ClassCastException e) {
throw new ClassCastException("Activity must implement NavigationDrawerCallbacks.");
}

Android Navigation Drawer can't click on one item

I have a really interesting problem with my Navigator menu.
I have no idea why... But I can click on any item from my menu, I don't want to say I click and nothing happened. I really want to say I can't click on any item, all my menu it's like a big image.
I've try to make a new project witch already have Navigation Drawer Activity, of course it works.. but when I've try to copy that code and put on mine.. I have the same problem and vice versa, I've try to put my code into a new project with Navigation Drawer Activity, but again... I can't click on any item.
Here it's one image with my aplication.
Here it's my Main Activity:

How to call NavigationDrawer.syncState() from Fragment?

I am attempting to use Kanytu's android-material-drawer-template to implement a Navigation Drawer that meets Google's material design guidelines. The issue I'm facing is: Upon selecting a fragment to transition to from the navigation drawer, the selected fragment will successfully replace the current fragment within the 'container' FrameLayout. However, the HomeAsUp Indicater will display a "Back" navigation arrow in the Toolbar, rather than the Hamburger Icon needed to open the Navigation Drawer.
From what I can gather, this is due to the ActionBarDrawerToggle becoming out of sync when the fragments are being swapped. Assuming this to be the issue (I'm open for suggestions), how could I call .syncState() within the NavigationActivity fragments on the current ActionBarDrawerToggle?
public class NavigationActivity extends ActionBarActivity implements NavigationDrawerCallbacks {
private Toolbar mToolbar;
private NavigationDrawerFragment mNavigationDrawerFragment;
#Override
protected void onCreate( #Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation);
mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
if (mToolbar != null) {
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
mNavigationDrawerFragment = (NavigationDrawerFragment) getFragmentManager().findFragmentById(R.id.fragment_drawer);
mNavigationDrawerFragment.setup(R.id.fragment_drawer, (DrawerLayout) findViewById(R.id.drawer), mToolbar);
if (findViewById(R.id.container) != null) {
// However, if we're being restored from a previous state,
// then we don't need to do anything and should return or else
// we could end up with overlapping fragments.
if (savedInstanceState != null) {
return;
}
}
}

/**

*/

}
while this is the code for switch:
public void onNavigationDrawerItemSelected(int position) {
FragmentManager fragmentManager = getSupportFragmentManager();
Fragment fragment = null;
switch (position) {
case 0:
fragment = new MetaioFragment();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment)
.commit();
break;
case 1:
/*
fragment = new GalleryFragment();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment)
.commit();
*/
Intent i = new Intent(this,MyActivity.class);
startActivity(i);
break;
with fragment I have no problem while if I try to open an activity I get this error:
java.lang.RuntimeException: Unable to start activity ComponentInfo java.lang.IllegalArgumentException: No view found for id 0x7f080044 for fragment MyFragment{65777f20 #1 id=0x7f080044}
and a lot of other error, where is the mistake?

You are missing setContentView. Your Fragment can not be added without a View hierarchy.
Your issue is possibly similar to this one.
