I would just like to add that if you are getting  deprecated  message when using getDrawable      you should use the following method from the support library instead    ContextCompat getDrawable getContext   R drawable  name     You do not have to use getResources   when using this method    This is equivalent to doing something like  Drawable mDrawable  if android os Build VERSION SDK INT  gt   android os Build VERSION CODES LOLLIPOP       mDrawable   ContextCompat getDrawable getContext   R drawable  name      else       mDrawable   getResources   getDrawable R id  name        This works on both pre and post Lollipop versions
