  • @user3456519 do you know what Drawable class is for? if so try to call setProgressDrawable with your own custom Drawable – pskink Mar 26 '14 at 12:56

try this: 

yourProgressBar.getProgressDrawable().setColorFilter(Color.RED, Mode.MULTIPLY);

in your case:

((ProgressBar)findViewById(id)).getProgressDrawable().setColorFilter(Color.RED, Mode.MULTIPLY);
