Android Question
The method onKeyDown(int, KeyEvent) is undefined for the type Fragment
I am trying to detect if the back button was pressed in one of my Fragments using onKeyDown but I get the error
The method onKeyDown(int, KeyEvent) is undefined for the type Fragment
at the end of the function. Is there a way to use this function in Fragments?
public class FragmentStory4 extends Fragment {
public FragmentStory4 () {
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_story4, container,
false);
return view;
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
}
return super.onKeyDown(keyCode, event);
}
}

Try this and tell me :)
fragment.getView().setOnKeyListener( new OnKeyListener()
{
@Override
public boolean onKey( View v, int keyCode, KeyEvent event )
{
if( keyCode == KeyEvent.KEYCODE_BACK )
{
return true;
}
return false;
}
} );
