I've tried almost everything but nothing seems to work. I have a navigation drawer with these fragments, say: A - viewpager B - listview C - listview Now in B and C, listview are clickable items with each having their own fragments. So ListViewA has a fragment, ListViewB has a fragment. I want proper back navigation. This is how I'm doing it, when initializing the navigation drawer:
Fragment fragment = getHomeFragment();
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.setCustomAnimations(android.R.anim.fade_in,
android.R.anim.fade_out);
fragmentTransaction.replace(R.id.frame, fragment, CURRENT_TAG);
fragmentTransaction.commit();
And when choosing an option from listview:
final FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(android.R.anim.fade_in,
android.R.anim.fade_out);
ft.replace(R.id.frame, new FragmentB(),"HubSettings");
ft.addToBackStack(null);
ft.commit();
If I put addtoBackStack() in both transactions, back navigation works fine but navigation drawer title is not being set properly. I want to disable back button and force changing fragments from navigation drawer so that action bar title is set properly. How do I disable back button when it comes to CFragment?
One can go from menu like: Navigation Drawer->B Fragment->Listview option 1 Fragment Pressing Back -> Back to B Fragment -> Disable Back Button
Just override onBackPressed
in your Activity which contains the fragments like this:
@Override
public void onBackPressed() {
int count = getSupportFragmentManager().getBackStackEntryCount();
if (count > 0) {
getSupportFragmentManager().popBackStack();
updateDrawerToggle();
}
}
