Notification on View added to parent?

Question

When I build a View in Android dynamically I have to add it to a "parent" ViewGroup by calling

myLinearLayout.addView(myView);

I know that I can supervise the ViewGroup for any children to be added via the excellent onHierarchyChangeListener, but in my case I need the feedback in the View itself. Therefore my question is:

Is there something like a View.onAddedToParent() callback or a listener that I can build on?

To make things very clear: I want the view to handle everything on its own, I am aware of the fact that I could catch the event in the "parent" and then notify the view about things, but this is not desired here. I can only alter the view

Edit: I just found onAttachStateChangeListener and it would seem to work for most situations, but I'm wondering if this is really the correct solution. I'm thinking a View might just as well be passed on from one ViewGroup to another without being detached from the window. So I would not receive an event even though I want to. Could you please elaborate on this if you have insight?

Thanks in advance

You can create custom view and do your stuff in its onAttachedToWindow

public class CustomView extends View {

   public CustomView(Context context) {
       super(context);
   }

   @Override
   protected void onAttachedToWindow() {
       super.onAttachedToWindow();
       Log.d("CustomView", "onAttachedToWindow called for " + getId());
       Toast.makeText(getContext(), "added", 1000).show();
   }
}

If you want to ensure that your customview added to correct viewgroup which you want

@Override
 protected void onAttachedToWindow() {
    // TODO Auto-generated method stub
    super.onAttachedToWindow();

    if(((View)getParent()).getId()== R.id.relativelayout2)
    {           
        Log.d("CustomView","onAttachedToWindow called for " + getId());
        Toast.makeText(context, "added", 1000).show();          
    }

}
