Android RatingBar change star colors [closed]

Question

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.

Try this, if you only want to change color:

RatingBar ratingBar = (RatingBar) findViewById(R.id.ratingBar);
LayerDrawable stars = (LayerDrawable) ratingBar.getProgressDrawable();
stars.getDrawable(2).setColorFilter(Color.YELLOW, PorterDuff.Mode.SRC_ATOP);

The easiest way that worked for me...if you are extending AppCompat Activity

In your build.gradle add latest appcompat library.

dependencies {  
    compile 'com.android.support:appcompat-v7:X.X.X' // where X.X.X version
}

Make your activity extend android.support.v7.app.AppCompatActivity

public class MainActivity extends AppCompatActivity {  
    ...
}

Declare custom style in your styles.xml file.

<style name="RatingBar" parent="Theme.AppCompat">  
    <item name="colorControlNormal">@color/indigo</item>
    <item name="colorControlActivated">@color/pink</item>
</style>  

Apply this style to your RatingBar via android:theme attribute.

<RatingBar  
    android:theme="@style/RatingBar"
    android:rating="3"
    android:stepSize="0.5"
    android:numStars="5"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

From the API 21 on it's very easy to change the color of the stars with this three lines of code:

android:progressTint="@android:color/holo_red_dark"
android:progressBackgroundTint="@android:color/holo_red_dark"
android:secondaryProgressTint="@android:color/holo_red_dark" 

Doing it like this, you'll change:

• the filled stars color (progressTint)
• the unfilled stars color (progressBackgroundTint)
• and the border color (secondaryProgressTint) of the stars

2015 Update

Now you can use DrawableCompat to tint all kind of drawables. For example:

Drawable progress = ratingBar.getProgressDrawable();
DrawableCompat.setTint(progress, Color.WHITE);

This is backwards compatible up to API 4

If you want to change color for all stars states you my use:

LayerDrawable stars = (LayerDrawable) ratingBar.getProgressDrawable();
stars.getDrawable(2).setColorFilter(getResources().getColor(R.color.starFullySelected), PorterDuff.Mode.SRC_ATOP);
stars.getDrawable(1).setColorFilter(getResources().getColor(R.color.starPartiallySelected), PorterDuff.Mode.SRC_ATOP);
stars.getDrawable(0).setColorFilter(getResources().getColor(R.color.starNotSelected), PorterDuff.Mode.SRC_ATOP);

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.
