Answer 1

Finally I found my god dammit solution. the problem is I use KeyboardVisibilityEvent library to control hide and visibility keyboard.

I use this code to control:

KeyboardVisibilityEvent.setEventListener(getActivity(), this::updateKeyboardStatusText); 

but I must pass the activity in method to handle life cycle

KeyboardVisibilityEvent.setEventListener(getActivity(), getActivity(), this::updateKeyboardStatusText);

hope help someone. thanks everyone
