In addition to Shayne3000 s answer you can also use a color resource  not only an int color   Kotlin version   var indicatorViewDrawable   itemHolder indicatorView background indicatorViewDrawable   DrawableCompat wrap indicatorViewDrawable  val color   ResourcesCompat getColor context resources  R color AppGreenColor  null     get your color from resources DrawableCompat setTint indicatorViewDrawable  color  itemHolder indicatorView background   indicatorViewDrawable

You could use  button setBackgroundTintList ColorStateList valueOf resources getColor R id blue 100       But I would recommend you to use a support library drawable tinting which just got released yesterday   Drawable drawable            Wrap the drawable so that future tinting calls work    on pre-v21 devices  Always use the returned drawable  drawable   DrawableCompat wrap drawable       We can now set a tint DrawableCompat setTint drawable  Color RED         or a tint list DrawableCompat setTintList drawable  myColorStateList         and a different tint mode DrawableCompat setTintMode drawable  PorterDuff Mode SRC OVER     You can find more in this blog post  see section  Drawable tinting

If you are using Kotlin and Material Design  you can change color of your MaterialButton like this    myButton background setTintList ContextCompat getColorStateList context  R color myColor     You can improve it even better by creating an extension function for your MaterialButton in order to make you code more readable and your coding little more convenient   fun MaterialButton changeColor color  Int        this background setTintList ContextCompat getColorStateList context  color       Then  you can use your function everywhere like this    myButton changeColor R color myColor

Have you tried something like this   button setBackgroundTintList getResources   getColorStateList R id blue 100      note that getResources   will only work in an activity  But it can be called on every context too

The suggested answer here doesn t work properly on android 5 0 if your XML based color state list references themed attributes   For instance  I have an xml color state list like so    lt  xml version  1 0  encoding  utf-8   gt   lt selector xmlns android  http   schemas android com apk res android  gt       lt item android color   colorPrimary  android state enabled  true   gt       lt item android alpha  0 12  android color   attr colorOnSurface   gt   lt  selector gt    Using this as my backgroundTint from xml works just fine on android 5 0 and everything else  However if I try to set this in code like this    Don t do this   myButton setSupportButtonTintList ContextCompat getColorStateList myButton getContext    R color btn tint primary      It actually doesn t matter if I pass the Activity or the button s context to ContextCompat getColorStateList   method  neither will give me the proper color state list with respect to the theme the button is within  This is because using theme attributes in color state lists wasn t supported until api 23 and ContextCompat does not do anything special to resolve these  Instead you must use AppCompatResources getColorStateList   which does its own resource parsing theme attribute resolution on devices  lt  API 23    Instead  you must use this   myButton setSupportBackgroundTintList AppCompatResources getColorStateList myButton getContext    R color btn tint primary      TLDR  use AppCompatResources and not -ContextCompat- if you ll need resolved themed resources across all API versions of android   For more information on the topic  see this article

this is easily handled in the new Material Button from material design library  first  add the dependency   implementation  com google android material material 1 1 0-alpha07    then in your XML  use this for your button    lt com google android material button MaterialButton     android id    id accept      android layout width  match parent      android layout height  wrap content      android text   string i accept      android textSize  18sp      app backgroundTint   color grayBackground 500    gt    and when you want to change the color  here s the code in Kotlin  It s not deprecated and it can be used prior to Android 21   accept backgroundTintList   ColorStateList valueOf ResourcesCompat getColor resources   R color colorPrimary  theme

I had a similar problem  I wished to colour a complex drawable background for a view based on a color  int  value  I succeeded by using the code   ColorStateList csl   new ColorStateList new int          new int   color    textView setBackgroundTintList csl     Where color is an int value representing the colour required  This represents the simple xml ColorStateList    lt selector xmlns android  http   schemas android com apk res android   gt       lt item android color  color here   gt   lt  selector gt    Hope this helps

In properly extending dimsuz s answer by providing a real code situation  see the following code snippet       Drawable buttonDrawable   button getBackground        buttonDrawable   DrawableCompat wrap buttonDrawable         the color is a direct color int and not a color resource     DrawableCompat setTint buttonDrawable  Color RED       button setBackground buttonDrawable     This solution is for the scenario where a drawable is used as the button s background  It works on pre-Lollipop devices as well
