I am replacing a NavigationView with a Fragment, and working further with the view. (Since NavigationView is a child of FrameLayout)
When clicking on any item in NavView .. I overlay the NavView with a fragment. If someone clicks back button .. I want to come back to the NavView.
When replacing the NavigationView with a Fragment, I have put a toolbar.
Problem
a. The toolbar shows a 'back' link - But it doesn't work.
b. The toolbar shows the 'Settings' menu - I do NOT want this on the Fragment. But .. i still want the 'Settings' menu on the MainActivity toolbar.
c. The toolbar seems to underlap with the StatusBar - How do i put the toolbar beneath the StatusBar, in the Fragment.
Options tried
a. OnBackPressed method of MainActivity - fragmentManager.popUpStack()
b. onOptionsItemSelected() method of Fragment -fragmentManager.popUpStack()
c. Created a listener on Toolbar, in onClick method : fragmentManager.popUpStack()
Screenshot:
Here is my code :
MainActivity:> onNavigationItemSelected()
@Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_camera) {
// Handle the camera action
} else if (id == R.id.nav_gallery) {
} else if (id == R.id.nav_slideshow) {
} else if (id == R.id.nav_manage) {
} else if (id == R.id.nav_share) {
} else if (id == R.id.nav_send) {
}
ItemsFragment fragment = new ItemsFragment();
android.support.v4.app.FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.nav_view, fragment);
// fragmentTransaction.setTransition();
fragmentTransaction.addToBackStack("LeftMainNavDrawer");
fragmentTransaction.commit();
// DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
// drawer.closeDrawer(GravityCompat.START);
return true;
}
