title: Android - font (only letters) background color
body: <p>I want to make in my application some meme - type images. 
  <br/><br/>I've found some fonts, which I can use, but one thing, which is connecting them is, that when I'm changing textColor property for TextView, which is contining text, I'm changing contour of letters, not whole letter color. When I'm changing background color, I'm changing whole TextView field background (and I want it to be transparent). And the problem is, that in letter I can see background image of photo, which is under the letter, which is problem, because photos can have different colors and text could be not visible. Is there any possibility, to change background color, but only for letters? Or it is a job for someone who is working with graphics and fonts?
  <br/><br/>
  There is a photo, which is from my app, which is showing problem.
