any suggestions helpful

text alginment doesn't take gravity constant. has own set. see http://developer.android.com/reference/android/view/view.html#settextalignment%28int%29 you're doing off.

generally right way either set layout_gravity of textview, or align textview way want, depending on size of string , effect you're trying get.
