Question

I need to get the correct coordinates from the method of View.
getLocationOnScreen (locationOnScreen). But in the method View.onCreate() view created yet. What method can I get the correct position of view relative to Activity?

Answer 1

final ViewTreeObserver vto = myView.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
    public void onGlobalLayout() {
        // ...
        vto.removeGlobalOnLayoutListener(this);
    }
}
