本篇文章是對(duì)在Android下修改SeekBar樣式的解決辦法進(jìn)行了詳細(xì)的分析介紹，需要的朋友參考下

SeekBar配置文件：
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代碼

復(fù)制代碼代碼如下:

<?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>    

     <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：用圖片如下：
Xml代碼

復(fù)制代碼代碼如下:

<?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: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
Xml代碼

復(fù)制代碼代碼如下:

<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"就是那個(gè)會(huì)動(dòng)的球
配置如下：
Xml代碼

復(fù)制代碼代碼如下:

<?xml version="1.0" encoding="UTF-8"?>    
<selector xmlns:android="http://schemas.android.com/apk/res/android">          

    <!-- 按下狀態(tài)-->    
    <item     
        android:state_focused="true"     
        android:state_pressed="true"     
        android:drawable="@drawable/thumb_pressed" />          
    <!-- 普通無焦點(diǎn)狀態(tài) -->    
    <item     
        android:state_focused="false"     
        android:state_pressed="false"    
        android:drawable="@drawable/thumb_normal" />                
    <!-- 有焦點(diǎn)狀態(tài)-->    
    <item     
        android:state_focused="true"     
        android:state_pressed="false"                
        android:drawable="@drawable/thumb_focused" />           
    <!-- 有焦點(diǎn) -->    
    <item     
        android:state_focused="true"                
        android:drawable="@drawable/thumb_focused" />       
</selector>
