Layout TextView Hint not always showing

Question

I have 4 textview, all numbers. The first one "#" is the hint and it shows up on my 4.2 and 2.2. The next three are "Hours, Minutes, Seconds" respectively and the hint shows up on 4.2 but not 2.2. Here is my xml for the them.

First Textview has # and the next three will say Hour, Minute, Second.

Answer 1

Somehow setting center_horizontal value in the android:gravity is causing issues in Android 2.2 in displaying the hint.

Remove center_horizontal from the value of android:gravity to display the hint.
