Center Alignment in Android

Many Regards.

You need to set gravity for a view as CENTER_HORIZONTAL

with the markup you should use:

android:layout_gravity="center_vertical|center_horizontal"

The difference between android:gravity and android:layout_gravity is that android:gravity positions the contents of that view (i.e. what’s inside the view), whereas android:layout_gravity positions the view with respect to its parent

In the code you should use:

textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);

Most of the time, you don't have to do this if you defined android:gravity="center" in the layout file.

You can also perform this by getting the screen size then doing some calculations on it, but this is not recommended.
