Android RatingBar change star colors

Question

How can i change the star colors and how can i change the size of the stars ?

Answer 1

Step #1: Create your own style, by cloning one of the existing styles (from $ANDROID_HOME/platforms/$SDK/data/res/values/styles.xml), putting it in your own project's styles.xml, and referencing it when you add the widget to a layout.

Step #2: Create your own LayerDrawable XML resources for the RatingBar, pointing to appropriate images to use for the bar. The original styles will point you to the existing resources that you can compare with. Then, adjust your style to use your own LayerDrawable resources, rather than built-in ones.

Answer 2

As the previous answer implies, it is not easy to change the color of the ratingbar. The stars are not programmatically drawn, they are images with fixed size and specific color gradients. To change the color you have to create your own star images with different colors then proceed to create your own drawable XML resource and pass it to the ratingsBar class using setProgressDrawable(Drawable d) or XML attribute android:progressDrawable.

I wrote a blog post describing how to change RatingBar images: http://kozyr.zydako.net/2010/05/23/pretty-ratingbar/

It also shows where you can specify image size...
