Android - reacting after initial layout

Question

This question has been asked several times in various forms but I haven\'t found a definitive answer.

I need to be able to get dimensions and positions of descendant

Answer 1

I've been successful using the OnGlobalLayoutListener.

It worked great on my Nexus S

final LinearLayout marker = (LinearLayout) findViewById(R.id.distance_marker);
OnGlobalLayoutListener listener = new OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        //some code using marker.getHeight(), etc.
        markersContainer.getViewTreeObserver().removeGlobalOnLayoutListener(this);
    }
};
marker.getViewTreeObserver().addOnGlobalLayoutListener(listener);
