使用Android RatingBar,我希望评级星有以下颜色(所有星星每个评级的颜色相同):

  • 一颗星:红色
  • 两颗星:黄色
  • 三颗星:蓝色
  • 四颗星:绿色
  • 五颗星:深绿色

这是我的代码:

RatingBar rateDoctor;

rateDoctor = (RatingBar)findViewById(R.id.rateDoctor);

rateDoctor.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
    @Override
    public void onRatingChanged(RatingBar ratingBar, float v, boolean b) {


    }
});

我的XML:

<RatingBar android:id="@+id/rateDoctor" android:layout_marginTop="15dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:numStars="5" android:stepSize="1.0" />

试试这个

if(ratingbar.getRating()<=1)
{
LayerDrawable stars = (LayerDrawable) ratingBar
                .getProgressDrawable();
        stars.getDrawable(2).setColorFilter(getResources().getColor(R.color.red),
                PorterDuff.Mode.SRC_ATOP); // for filled stars
        stars.getDrawable(1).setColorFilter(getResources().getColor(R.color.hal_selected),
                PorterDuff.Mode.SRC_ATOP); // for half filled stars
        stars.getDrawable(0).setColorFilter(getResources().getColor(R.color.no_selected),
                PorterDuff.Mode.SRC_ATOP);
}
