title: Child view focus change android
body: <p>I have a <code>ViewGroup</code> that can have many <code>LinearLayout</code>s. And each <code>LinearLayout</code> can have many nested child views. What I want is that, if any view(even deep nested) inside a <code>LinearLayout</code> gets focus, it should call a custom method of its main parent <code>LinearLayout</code>.</p>
  
  <p>The last thing I want to do is, set <code>OnFocusChangeListener</code> on every single deep nested child views of <code>LinearLayout</code> and that listener will call its parent's custom method. But that is really bad way to go for.</p>
  
  <p>Is there any method I can override of parent <code>LinearLayout</code> that gets called every time its any nested child view's focus changes ?</p>
