    To accomplish this in my app, I had to find a View's dimensions within the main Activity. It looked something like this:

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    
        gestureScanner = new GestureDetector(this);   //Object for handling gestures.
    
        mvView = new MyView(this);  //MyView is class that extends View.
        setContentView(myView);
    }
    
    @Override
    public void onShowPress(MotionEvent e) {
    
        //Returns the size of the entire window, including status bar and title.
        DisplayMetrics dm = new DisplayMetrics();
        this.getWindowManager().getDefaultDisplay().getMetrics(dm);
    
        //Try to find the dimension of the view without the status/title bars.
        int iViewHeight = mvMountain.getHeight();
        int iViewWidth = mvMountain.getWidth();
    
    
        Toast toast = Toast.makeText(this," View:" + iViewWidth + ","+iViewHeight + " Window: " + dm.widthPixels + " by " + dm.heightPixels, 2);
        toast.show();
    }
