How to find the Width of the a view before the view is displayed?

Question

How to find the Width of the a view before the view is displayed? I do not want to add a custom view and tap the dimensions in the OnChanged().

Answer 1

You should use OnGlobalLayoutListener which is called for changes on the view, but before it is drawn.

costumView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

    @Override
    public void onGlobalLayout() {

      costumView.getWidth();

    }
});
