How to get the height value of the TextView field before running the application?

Question

Android

Hello, in my application I need to get the value of the height of the text field when the application has started, but it has not yet been interacted with. For example, display a Toast message with the height value immediately after launch.

Try like this

someTextView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                //here
            }
        });
