Android之RatingBar实现评论星级效果

效果图：

1.布局

  

   

    

     

    
    

     

      <RatingBar
     
    
   

    

     

    
    

     
        android:id="@+id/ratingbar"
     
    
   

    

     

    
    

     
        android:layout_width="wrap_content"
     
    
   

    

     

    
    

     
        android:layout_height="wrap_content"
     
    
   

    

     

    
    

     
        android:numStars="5"	//设置数量
     
    
   

    

     

    
    

     
        android:rating="3"	//设置默认选中
     
    
   

    

     

    
    

     
        style="@style/mRatingBar"
     
    
   

    

     

    
    

     
        android:progressTint="@android:color/holo_orange_dark"	//设置颜色
     
    
   

    

     

    
    

     
        android:stepSize="1" />	//设置选中数值
     
    
  
 

  

   

    

     

    
    

     

      <?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/ratingbar_normal" />
     
    
   

    

     

    
    

     
    <item android:id="@android:id/secondaryProgress" android:drawable="@drawable/ratingbar_normal" />
     
    
   

    

     

    
    

     
    <item android:id="@android:id/progress" android:drawable="@drawable/ratingbar_checked" />
     
    
   

    

     

    
    

     

      </layer-list>
     
    
  
 

3.style

  

   

    

     

    
    

     

      <style name="mRatingBar" parent="@android:style/Widget.RatingBar">
     
    
   

    

     

    
    

     
        <item name="android:progressDrawable">@drawable/ratingbar</item>
     
    
   

    

     

    
    

     
        <item name="android:minHeight">38dp</item>
     
    
   

    

     

    
    

     
        <item name="android:maxHeight">38dp</item> //这里是图片的高度
     
    
   

    

     

    
    

     
    </style>
     
    
  
 

  

   

    

     

    
    

     

      	RatingBar mRatingBar = (RatingBar) findViewById(R.id.ratingbar);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

              mRatingBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

                  @Override
     
    
   

    

     

    
    

     

                  public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
     
    
   

    

     

    
    

     

                      Toast.makeText(MainActivity.this, "评分星级=" + rating, Toast.LENGTH_SHORT).show();
     
    
   

    

     

    
    

     

                  }
     
    
   

    

     

    
    

     

              });
     
    
  
 

设置监听，第二个参数就是数值

也可以用对象去get

float rating = mRatingBar.getRating();//获取星级
