background drawable does not fit in bound of TextView in Android

Question

I made a TextView which has attributes of background, gravity and so on. and i made a drawable resource file for the TextView's background. and this is the xml.

and i added the drawable resource into background of the TextView.

but the problem is, the background doesn't fit in Textview's bound. please look at this photo.

there is a gap very slightly. the background color area is upper than TextView's area. so i tried to use includeFontPadding attribute but it didn't work. how can i fix it?

Answer 1

I would advise you to check this on real device/emulator, not on preview in AS. use Show Layout Bounds option from developer options for verification, make some full-resolution screen shot and check on it. it will be properly placed

content of any View , including its background, is always places inside its bounds. really, always, its just impossible to get outside with a single pixel (due to layout building and drawing mechanism)

Answer 2

Nothing is wrong with the code. In the Design Editor, it shows like this when we use any background drawable with any view. There is not any kind of a glitch.
