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

I like to use this technique as per my answer on a related question:

Post a runnable from onCreate() that will be executed when the view has been created:

    contentView = findViewById(android.R.id.content);
    contentView.post(new Runnable()
    {
        public void run()
        {
            contentHeight = contentView.getHeight();
        }
    });

This code will run on the main UI thread, after onCreate() has finished.
