Android下修改SeekBar样式

推荐安卓开发神器（里面有各种UI特效和android代码库实例）

SeekBar配置文件：

Xml代码

<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"  
         />

<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:

Xml代码

或者：用图片如下：

Xml代码

<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>  
view plaincopy to clipboardprint?

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

       android:drawable="@drawable/second_progress">

 <item android:id="@android:id/progress"  
       android:drawable="@drawable/first_progress">  
       
 </item>   
</layer-list>  

方形

Xml代码

<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 android:id="@android:id/progress">   
         <clip android:drawable="@drawable/first_progress" />   
    </item>   
  
  
</layer-list>  
view plaincopy to clipboardprint?
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

         <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：

Xml代码

<?xml version="1.0" encoding="UTF-8"?>  
<selector xmlns:android="http://schemas.android.com/apk/res/android">        
       
    <!-- 按下状态-->  
    <item   
        android:state_focused="true"   
        android:state_pressed="true"   
        android:drawable="@drawable/thumb_pressed" />        
    <!-- 普通无焦点状态 -->  
    <item   
        android:state_focused="false"   
        android:state_pressed="false"  
        android:drawable="@drawable/thumb_normal" />              
    <!-- 有焦点状态-->  
    <item   
        android:state_focused="true"   
        android:state_pressed="false"              
        android:drawable="@drawable/thumb_focused" />         
    <!-- 有焦点 -->  
    <item   
        android:state_focused="true"              
        android:drawable="@drawable/thumb_focused" />     
</selector>
