Answer 1

Firstly, don't get view dimensions in onCreate() since the view might not have been initialized yet. You can do it in the onStart() method. All the views will have been inflated and laid out on the screen at that point:

@Override
    protected void onStart() {
        super.onStart();
        ScrollView scrollView = (ScrollView) findViewById(R.id.svtest);
        int width = scrollView.getWidth();
        int height = scrollView.getHeight();
    }
