<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"背景条

seekbar_style配置如下:

1. <?xml version="1.0" encoding="UTF-8"?>
3. <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
5. <item android:id="@android:id/background">

42. android:angle="270"
43. />
44. </shape>
45. </clip>
46. </item>
48. </layer-list>

<?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>     <item android:id="@android:id/progress">         <clip>             <shape>                 <corners android:radius="5dip" />                 <gradient                         android:startColor="#ff0099CC"                         android:centerColor="#ff3399CC"                         android:centerY="0.75"                         android:endColor="#ff6699CC"                         android:angle="270"                 />             </shape>         </clip>     </item> </layer-list>

或者：用图片如下：

1. <?xml version="1.0" encoding="utf-8"?>
2. <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
4. <item android:id="@android:id/background"
5. android:drawable="@drawable/progress_bg" />
7. <item android:id="@android:id/secondaryProgress"
8. android:drawable="@drawable/second_progress">
9. </item>
11. <item android:id="@android:id/progress"
12. android:drawable="@drawable/first_progress">
14. </item>
15. </layer-list>

<?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/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

1. <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
4. <item android:id="@android:id/background"
5. android:drawable="@drawable/progress_bg" />
8. <item android:id="@android:id/secondaryProgress">
9. <clip android:drawable="@drawable/second_progress" />
10. </item>
13. <item android:id="@android:id/progress">
14. <clip android:drawable="@drawable/first_progress" />
15. </item>
18. </layer-list>

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">     <item android:id="@android:id/background"     android:drawable="@drawable/progress_bg" />     <item android:id="@android:id/secondaryProgress">      <clip android:drawable="@drawable/second_progress" />     </item>     <item android:id="@android:id/progress">          <clip android:drawable="@drawable/first_progress" />     </item> </layer-list>

android:thumb="@drawable/thumb"就是那个会动的球

配置如下：

1. <?xml version="1.0" encoding="UTF-8"?>
2. <selector xmlns:android="http://schemas.android.com/apk/res/android">
4. <!-- 按下状态-->
5. <item
6. android:state_focused="true"
7. android:state_pressed="true"
8. android:drawable="@drawable/thumb_pressed" />
9. <!-- 普通无焦点状态 -->
10. <item
11. android:state_focused="false"
12. android:state_pressed="false"
13. android:drawable="@drawable/thumb_normal" />
14. <!-- 有焦点状态-->
15. <item
16. android:state_focused="true"
17. android:state_pressed="false"
18. android:drawable="@drawable/thumb_focused" />
19. <!-- 有焦点 -->
20. <item
21. android:state_focused="true"
22. android:drawable="@drawable/thumb_focused" />
23. </selector>
