Get Window Status Bar and Title Bar Height Size

Size of Bar

This is an interesting tip to get the height size of status bar and title bar, assuming that they are both on the top of screen.

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        tvContent = (TextView)findViewById(R.id.tvContent);
        tvContent.postDelayed(new Runnable() {

			@Override
			public void run() {
				 String display = String.format("Status Bar Height = %d\nTitle Bar Height = %d", getStatusBarHeight(), getTitleBarHeight());
			     tvContent.setText(display);

			}
		}, 2000);

    }

    public int getStatusBarHeight() {
    	Rect r = new Rect();
    	Window w = getWindow();
    	w.getDecorView().getWindowVisibleDisplayFrame(r);
    	return r.top;
    }

    public int getTitleBarHeight() {
    	int viewTop = getWindow().findViewById(Window.ID_ANDROID_CONTENT).getTop();
    	return (viewTop - getStatusBarHeight());
    }

The reason why getting directly inside onCreate() method doesnot work is because the view is being measured; so it’s better to retrieve the size after finishing measuring. In this case, I attach a handler to the TextView and run after 2 seconds delay. You also can run on a Listener as well.
