Note  Answer has been updated to cover the scenario where background is an instance of ColorDrawable  Thanks Tyler Pfaff  for pointing this out      The drawable is an oval and is the background of an ImageView   Get the Drawable from imageView using getBackground     Drawable background   imageView getBackground      Check against usual suspects   if  background instanceof ShapeDrawable           cast to  ShapeDrawable      ShapeDrawable shapeDrawable    ShapeDrawable  background      shapeDrawable getPaint   setColor ContextCompat getColor mContext R color colorToSet      else if  background instanceof GradientDrawable           cast to  GradientDrawable      GradientDrawable gradientDrawable    GradientDrawable  background      gradientDrawable setColor ContextCompat getColor mContext R color colorToSet      else if  background instanceof ColorDrawable           alpha value may need to be set again after this call     ColorDrawable colorDrawable    ColorDrawable  background      colorDrawable setColor ContextCompat getColor mContext R color colorToSet        Compact version   Drawable background   imageView getBackground    if  background instanceof ShapeDrawable          ShapeDrawable background  getPaint   setColor ContextCompat getColor mContext R color colorToSet      else if  background instanceof GradientDrawable          GradientDrawable background  setColor ContextCompat getColor mContext R color colorToSet      else if  background instanceof ColorDrawable          ColorDrawable background  setColor ContextCompat getColor mContext R color colorToSet        Note that null-checking is not required   However  you should use mutate   on the drawables before modifying them if they are used elsewhere   By default  drawables loaded from XML share the same state

May be I am too late But if you are using Kotlin  There is way like this  var gd   layoutMain background as GradientDrawable     gd setCornerRadius 10    gd setColor ContextCompat getColor ctx   R color lightblue     gd setStroke 1  ContextCompat getColor ctx   R color colorPrimary       Strokewidth colorId    Enjoy

The simple way to fill the shape with the Radius is    view getBackground    setColorFilter Color parseColor   FFDE03    PorterDuff Mode SRC IN

Expanding on Vikram s answer  if you are coloring dynamic views  like recycler view items  etc     Then you probably want to call mutate   before you set the color  If you don t do this  any views that have a common drawable  i e a background  will also have their drawable changed colored   public static void setBackgroundColorAndRetainShape final int color  final Drawable background         if  background instanceof ShapeDrawable              ShapeDrawable  background mutate    getPaint   setColor color         else if  background instanceof GradientDrawable              GradientDrawable  background mutate    setColor color         else if  background instanceof ColorDrawable              ColorDrawable  background mutate    setColor color        else          Log w TAG  Not a valid background type

This question was answered a while back  but it can modernized by rewriting as a kotlin extension function    fun Drawable overrideColor  ColorInt colorInt  Int        when  this            is GradientDrawable - gt  setColor colorInt          is ShapeDrawable - gt  paint color   colorInt         is ColorDrawable - gt  color   colorInt

My Kotlin extension function version based on answers above with Compat   fun Drawable overrideColor Ext context  Context  colorInt  Int        val muted   this mutate       when  muted            is GradientDrawable - gt  muted setColor ContextCompat getColor context  colorInt           is ShapeDrawable - gt  muted paint setColor ContextCompat getColor context  colorInt           is ColorDrawable - gt  muted setColor ContextCompat getColor context  colorInt           else - gt  Log d  Tag    Not a valid background type

A simpler solution nowadays would be to use your shape as a background and then programmatically change its color via    view background setColorFilter Color parseColor   343434    PorterDuff Mode SRC ATOP    See PorterDuff Mode for the available options   UPDATE  API 29    The above method is deprecated since API 29 and replaced by the following   view background colorFilter   BlendModeColorFilter Color parseColor   343434    BlendMode SRC ATOP    See BlendMode for the available options
