Android dispatchKeyEvent not called when Dialog fragment is show

Question

when my dialog fragment is hide, dispatchKeyEvent worked fine

@Override
public boolean dispatchKeyEvent(KeyEvent event) {

    Toast.makeText(FragmentPlayer.this, "test: called", Toast.LENGTH_SHORT).show();

    return super.dispatchKeyEvent(event);

}

but when my dialog fragment is show, dispatchKeyEvent not called

MyDialogFragment mFragment = new MyDialogFragment();
mFragment.show(getSupportFragmentManager(), "MyDialog");

why?

No need to change your DialogFragment code to Dialog, you can do something like this (In case still needed). Using OnKeyListener will solve your problem.

public class BaseDialogFragment extends AppCompatDialogFragment {

  @Override
  public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    getDialog().setOnKeyListener(new DialogInterface.OnKeyListener() {
        @Override
        public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
            /* Your logic, you get the KeyEvent*/
            return false;
        }
    });
}
