body: <p>Is there such a method call "getBackgroundColor" in TextView?
  if I got 2 textViews: tv1 and tv2 in one LinearLayout. What I did:tv1.setBackgroundColor(Color.BLUE) </p>
  
  <p>Now if I wanna setBackgroundColor of tv2 as the same as tv1, how can I <strong>get the backgroundColor</strong> in tv1 first and then setBackgroundColor of tv2?</p>
