Setting the Color of a TextView Drawable

Try below solution

private void setTextViewDrawableColor(TextView textView, int color) {
        for (Drawable drawable : textView.getCompoundDrawables()) {
            if (drawable != null) {
                drawable.setColorFilter(new PorterDuffColorFilter(ContextCompat.getColor(textView.getContext(), color), PorterDuff.Mode.SRC_IN));
            }
        }
    }

Please, notice that if you set drawables in your layout file via android:drawableStart or android:drawableEnd instead of android:drawableLeft and android:drawableRight respectively you should use TextView.getCompoundDrawablesRelative(). Otherwise you can get empty array of drawables.

private void setTextViewDrawableColor(TextView textView, int color) {
    for (Drawable drawable : textView.getCompoundDrawablesRelative()) {
        if (drawable != null) {
            drawable.setColorFilter(new PorterDuffColorFilter(ContextCompat.getColor(textView.getContext(), color), PorterDuff.Mode.SRC_IN));
        }
    }
}

I am using this in kotlin:

tv.getCompoundDrawables()[0].setTint(//color)
