Android Question Fontawesome wont fill button

[Shivito1]

font awesome wont fill button on every device.
colordrawable
I have set padding = 0,0,0,0

Screen size is different on every device but I think there should be a way to intelligently have it adapt according to screen size.

The text will not automatically fill the available space. You can use AutoTextSizeLabel: https://www.b4x.com/android/forum/threads/custom-view-autotextsizelabel.30642/#content
