Answer 1

final View view = findViewById(R.id.root);
ViewTreeObserver vto = view.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        // calculate the height in here...

        ViewTreeObserver vto = view.getViewTreeObserver();
        vto.removeGlobalOnLayoutListener(this);
    }
});

Use this listener inside onCreate (available since api 1). You will need to assign the id @+id/root to the parent in your xml layout. There is no way the size can return a result of 0, since this listener makes a callback whenever the layouts has been positioned in view.
