如何更換RatingBar的圖片

 

l1.在values下新建styles.xml文件

<?xml version="1.0" encoding="utf-8"?>   
<resources>     
        <style name="MyRatingBar" parent="@android:style/Widget.RatingBar">  
        <item name="android:progressDrawable">@drawable/circle_rating_bar_full</item>  
        <item name="android:minHeight">57dip</item>  
        <item name="android:maxHeight">72dip</item>  
    </style>  
</resources>  

2.在drawable下新建circle_rating_bar_full.xml文件並放置兩張圖片btn_circle_normal.png和btn_circle_pressed.png

<?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/btn_circle_normal"/>
    <item android:id="@+android:id/secondaryProgress"  
          android:drawable="@drawable/btn_circle_normal" />  
    <item android:id="@+android:id/progress"  
          android:drawable="@drawable/btn_circle_pressed" />  
</layer-list>
