xml代碼  

<seekbar   

         android:id="@+id/player_seekbar"  

         android:layout_width="245px"  

         android:layout_height="25px"  

         android:progressdrawable="@drawable/seekbar_style"  

         android:thumb="@drawable/thumb"  

         android:paddingleft="16px"  

         android:paddingright="15px"  

         android:paddingtop="5px"  

         android:paddingbottom="5px"  

         android:progress="0"  

         android:max="0"  

         android:secondaryprogress="0"  

         />    

 android:progressdrawable="@drawable/seekbar_style"背景條

seekbar_style配置如下:

<?xml version="1.0" encoding="utf-8"?>  

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">  

     <item android:id="@android:id/background">  

         <shape>  

             <corners android:radius="5dip" />  

             <gradient  

                     android:startcolor="#ff9d9e9d"  

                     android:centercolor="#ff5a5d5a"  

                     android:centery="0.75"  

                     android:endcolor="#ff747674"  

                     android:angle="270"  

             />  

         </shape>  

     </item>  

     <item android:id="@android:id/secondaryprogress">  

         <clip>  

             <shape>  

                 <corners android:radius="5dip" />  

                 <gradient  

                         android:startcolor="#80ffd300"  

                         android:centercolor="#80ffb600"  

                         android:centery="0.75"  

                         android:endcolor="#a0ffcb00"  

                         android:angle="270"  

                 />  

             </shape>  

         </clip>  

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

                         android:startcolor="#ff0099cc"  

                         android:centercolor="#ff3399cc"  

                         android:endcolor="#ff6699cc"  

 </layer-list>  

 或者：用圖檔如下：

    <item android:id="@android:id/background"   

          android:drawable="@drawable/progress_bg" />  

    <item android:id="@android:id/secondaryprogress"  

          android:drawable="@drawable/second_progress">  

    </item>     

    <item android:id="@android:id/progress"  

          android:drawable="@drawable/first_progress">  

    </item>   

</layer-list>  

 方形

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">   

    android:drawable="@drawable/progress_bg" />   

    <item android:id="@android:id/secondaryprogress">   

     <clip android:drawable="@drawable/second_progress" />   

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

         <clip android:drawable="@drawable/first_progress" />   

 android:thumb="@drawable/thumb"就是那個會動的球

  配置如下：

<selector xmlns:android="http://schemas.android.com/apk/res/android">       

    <!-- 按下狀态-->  

    <item   

        android:state_focused="true"   

        android:state_pressed="true"   

        android:drawable="@drawable/thumb_pressed" />       

    <!-- 普通無焦點狀态 -->  

        android:state_focused="false"   

        android:state_pressed="false"  

        android:drawable="@drawable/thumb_normal" />             

    <!-- 有焦點狀态-->  

        android:state_pressed="false"             

        android:drawable="@drawable/thumb_focused" />        

    <!-- 有焦點 -->  

        android:state_focused="true"
