I wrote a simple test project, but I cant understand why I always receive savedInstanceState = null in lifecycle methods onCreate, onCreateView and onActivityCreated. I change the screen orientation, see the log, but state not saved.
Tell me please where is my mistake.
Thanks.
The code of fragment class is:
public class TestFragment extends Fragment {
private String state = "1";
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (savedInstanceState != null) {
//never works
state = savedInstanceState.getString("state");
}
//always prints 1
Toast.makeText(getActivity(), state, Toast.LENGTH_SHORT).show();
return inflater.inflate(R.layout.fragment_layout, container, false);
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putString("state", "2");
Log.e("", "saved 2");
}
}
