}

its not working ...
the rating is wrong.when i choose 5 , it shows only 4 stars... like that

Thanks to @darzul and it works after this change.

Also I comment these 2 lines

drawable.findDrawableByLayerId(android.R.id.background).setColorFilter(backgroundTintColor, PorterDuff.Mode.SRC_ATOP);
drawable.findDrawableByLayerId(android.R.id.progress).setColorFilter(progressTintColor, PorterDuff.Mode.SRC_ATOP);

to respect the color defined in svg xml .

I have also commented these two lines, but the rating is wrong, it selects different number of stars than it should.
For example I select 3 stars, it will select 5 sometimes or if I select 2, it will show 3 or 4 are selected..

drawable.findDrawableByLayerId(android.R.id.background).setColorFilter(backgroundTintColor, PorterDuff.Mode.SRC_ATOP);
drawable.findDrawableByLayerId(android.R.id.progress).setColorFilter(progressTintColor, PorterDuff.Mode.SRC_ATOP);

gonna crash if the progressDrawble is LayerDrawable and it layer have one instance of StateListDrawable
