You can use    root setBackgroundColor 0xFFFFFFFF     or   root setBackgroundColor Color parseColor   ffffff

The previous answers are now deprecated  you need to use ContextCompat getColor to retrieve the color properly   root setBackgroundColor ContextCompat getColor getActivity    R color white

This must work   you must use getResources   getColor R color WHITE  to get the color resource  which you must add in the colors xml resource file  View someView   findViewById R id screen    someView setBackgroundColor getResources   getColor R color WHITE

If you save color code in the colors xml which is under the values folder then you should call the following   root setBackgroundColor getResources   getColor R color name      name means you declare in the  lt color  gt  tag

If you just want to use some of the predefined Android colors  you can use Color COLOR  where COLOR is BLACK  WHITE  RED  etc     myView setBackgroundColor Color GREEN     Otherwise you can do as others have suggested with   myView setBackgroundColor ContextCompat getColor getActivity    R color myCustomGreen      I don t recommend using a hex color directly  You should keep all of your custom colors in colors xml

In my case it wasn t changing the color because I was setting the color in my xml resource   After delete the line that set the color it worked perfectly programmatically  This is an example I did in a RecyclerView  final Drawable drawable   ContextCompat getDrawable mContext  R drawable ic icon  mutate     if  Build VERSION SDK INT  gt   Build VERSION CODES JELLY BEAN        holder image setBackground drawable     else       holder image setBackgroundDrawable drawable

you need to use getResources   method  try to use following code   View someView   findViewById R id screen   View root   someView getRootView    root setBackgroundColor getResources   getColor color white       Edit    getResources getColor   is deprecated so  use like below   root setBackgroundColor ContextCompat getColor this  R color white
