Seekbar 属性记录

android:progressDrawable="@drawable/layer_list_progressbar"

该属性：设置进度中的背景颜色和进度颜色

如下例子

<SeekBar
    android:id="@+id/player_seekbar"
    android:progressDrawable="@drawable/seekbar_style"
    android:background="@drawable/play_progress_background"
    android:layout_width="220dip"
    android:layout_height="wrap_content"
    android:thumb="@drawable/thumb"
    android:progress="0"
    android:max="0"
    />

seekbar_style.xml 如下：

<?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:
         android:drawable="@drawable/play_progress_background">         
           </item>    -->       
      
    <item android:id="@android:id/progress">
          
          <clip android:drawable="@drawable/play_progress"></clip>
               
          </item>   
        
</layer-list>

android:thumb

        android:state_focused="true"   
        android:state_pressed="true"   
        android:drawable="@drawable/play_progress_thumb_pressed" /> 
              
    <!-- 普通无焦点状态 -->  
    <item   
        android:state_focused="false"   
        android:state_pressed="false"  
        android:drawable="@drawable/play_progress_thumb_normal" />
