setBackgroundResource 0  is the best option  From the documentation      Set the background to a given resource  The resource should refer to a   Drawable object or 0 to remove the background    It works everywhere  because it s since API 1   setBackground was added much later  in API 16  so it will not work if your minSdkVersion is lower than 16
