ClassCastException: android.support.v4.graphics.drawable.DrawableWrapperHoneycomb cannot be cast to android.graphics.drawable.LayerDrawable

Question

I'm trying to change RatingBar stars color but after migrating to Android API 23 my following codes don't work and give me an exception.

LayerDrawable ratingBarStars = (LayerDrawable) holder.ratingBar.getProgressDrawable();
        ratingBarStars.getDrawable(0).setColorFilter(mContext.getResources()
                                                             .getColor(R.color.accent), PorterDuff.Mode.SRC_ATOP);
        ratingBarStars.getDrawable(1).setColorFilter(mContext.getResources()
                                                             .getColor(R.color.accent), PorterDuff.Mode.SRC_ATOP);
        ratingBarStars.getDrawable(2).setColorFilter(mContext.getResources()
                                                             .getColor(R.color.accent), PorterDuff.Mode.SRC_ATOP);

And the Error is:

java.lang.ClassCastException: android.support.v4.graphics.drawable.DrawableWrapperHoneycomb cannot be cast to android.graphics.drawable.LayerDrawable

obviously you cannot cast .... you should check if `getProgressDrawable()` returns instance of `LayerDrawable` or `DrawableWrapper` from support library and then do other stuff based on those classes — Selvin, Sep 07 '15 at 12:28
@Selvin Above codes were working before migrating to API 23! I know I cannot cast but how to solve it? I need to change stars color. — Alex, Sep 07 '15 at 12:30
question is: do you need this code at all .... it seems like they added ratingbar support in appcompat library ... so maybe it is already using accent color from AppCompat theme — Selvin, Sep 07 '15 at 12:32
@Selvin I changed to `AppCompatRatingBar` but nothing helped and same error. — Alex, Sep 07 '15 at 12:37
**question is: do you need this code at all**!!! if they added support for this why are you trying to change it by your own ... comment this code and see what would happend — Selvin, Sep 07 '15 at 12:37
@Selvin Sorry I didn't understand you. Can you please give me an example of changing those stars color? Thanks. — Alex, Sep 07 '15 at 12:39
`DrawableCompat.setTint(ratingBar.getProgressDrawable(), color)` — Selvin, Sep 07 '15 at 16:58
@Selvin Thank you so much. That worked like a charm. Please send your comment as an answer. Thanks. — Alex, Sep 07 '15 at 17:14

DrawableCompat.setTint(ratingBar.getProgressDrawable(),color); by Selvin in the comment section is the correct answer.

See https://stackoverflow.com/a/38207513/570168

tl;dr:

 layerDrawable = (LayerDrawable) rb.getProgressDrawable().getWrappedDrawable();
