Hamburger Icon does not show in Navigation Drawer Fragment

Question

I am using a Fragement for navigation drawer and hence can\'t use onPostCreated to call syncState

public class NavigationDrawerFragment extends Frag         


        

Answer 1

I had this problem as well. For me, importing android.support.v7.app.ActionBarDrawerToggle instead of android.support.v4.app.ActionBarDrawerToggle fixed it. You also have to remove the R.drawable.ic_drawer argument when you define mDrawerToggle:

mDrawerToggle = new ActionBarDrawerToggle( getActivity(), mDrawerLayout, R.string.navigation_drawer_open, R.string.navigation_drawer_close )

If that doesn't work, try some of the answers to this question.

Answer 2

The accepted answer was not solving it for me, I found out I had the wrong override for onPostCreate

@Override
public void onPostCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
    super.onPostCreate(savedInstanceState, persistentState);
    mDrawerToggle.syncState();
}

It must be

@Override
public void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    mDrawerToggle.syncState();
}
