How to align center the title or label in activity?

Question

I know there are two ways of setting the title of activity. One way is the setting it in the android manifest like this android:label=\"@string/app_name\".

Answer 1

I found another way of setting the title center, just put the code under the setContentView(R.layout.new)...

((TextView)((FrameLayout)((LinearLayout)((ViewGroup) getWindow().getDecorView()).getChildAt(0)).getChildAt(0)).getChildAt(0)).setGravity(Gravity.CENTER);

Hope this helps. Thanks!
