navigation-drawer

I have a normal NavigationDrawer with different fragments : News other Stuff 1 other Stuff 2 Setting The problem : The NewsFragment contains a SwipeRefreshLayout. It works great the first time I refresh. I can change fragment to other Stuff 1 and 2 and Setting. So I come back to NewsFragment. And now when I refresh, the fragment freezes. The drawerLayout works correctly (open/close, even the ActionBar Title change) but the main fragment stay at NewsFragment and I can't scroll. But the scollListner works (I have log) but the view doesn"t change. No refreshView (top of the swipeRefreshLayout),

I am getting this error at runtime. java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.app.ActionBar.setNavigationMode(int)' on a null object reference Main Activity.java public class MainActivity <T extends Fragment> extends ActionBarActivity implements ListView.OnItemClickListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ActionBar actionBar = getSupportActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); actionBar

I opened the default Android Studio App with a NavigationDrawer. The default content-view is not very useful, therefore I tried to replace it with a FrameLayout so I can add Fragments. If I just replace content_main with the FrameLayout the Fragment will not be shown at all. If I pull out the FrameLayout out of app_bar_main.xml into activity_main.xml it is shown but it overlaps with the Toolbar. MainActivity.java public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { @Override protected void onCreate(Bundle savedInstanceState) { super

I wanted to hide the view when clicking outside that view, for example, <Framelayout android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent" > <fragment android:id="@+id/map" android:name="com.google.android.gms.maps.SupportMapFragment" android:layout_width="match_parent" android:layout_height="match_parent" /> <ImageView android:id="@+id/imgButtonToOpenGrid" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="right|bottom" android:src="@drawable/open_grid_img" /> <RelativeLayout android:id="@+id

Can anybody help me to find the way to remove the left margin of the navigation drawer icon (mentioned by red rectangle below )? I am using toolbar here. This removes the left margin from toolbar. mainToolbar.setContentInsetsAbsolute(0, 0); Or you can set left inset to 0dp in toolbar xml: android:contentInsetLeft="0dp" Other way is to define that padding in the styles.xml: <style name="ToolbarStyle" parent="@style/Widget.AppCompat.Toolbar"> <item name="contentInsetStart">0dp</item> <item name="android:contentInsetStart">0dp</item> </style> If all of these solutions didn't worked please check

I started creating of app which use one activity (Navigation Drawer) and many fragments. But I unable to use toolbar back button to navigate back from fragments. Hardware back button works perfectly.

Here the code from activity: public class NavDrawerActivity extends AppCompatActivity implements
