Android RatingBar change star colors

Question

How can I change the star colors and size of the stars?

Answer 1

It's a little complicated at the mentioned blog, I've used a similar but simplier way. You do need 3 star images (red_star_full.png, red_star_half.png and red_star_empty.png) and one xml, that's all.

Put these 3 images at res/drawable.

Put there the following ratingbar_red.xml:

<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background" android:drawable="@drawable/red_star_empty" />
    <item android:id="@android:id/secondaryProgress" android:drawable="@drawable/red_star_half" />
    <item android:id="@android:id/progress" android:drawable="@drawable/red_star_full" />
</layer-list>

and, finally, tell your ratingbar definition to use this, i.e.

<RatingBar android:progressDrawable="@drawable/ratingbar_red"/>

That's it.
