SeekBar 的自定義樣式

代碼如下 

<SeekBar android:id="@android:id/progress"
        style="?android:attr/progressBarStyleHorizontal"
        android:progressDrawable="@drawable/seekbar_style"
        android:thumb="@drawable/thumb"
        android:layout_width="fill_parent"
        android:layout_height="23dip"
        android:paddingLeft="25dip"
        android:paddingRight="25dip"
        android:paddingBottom="4dip />

其實最最關鍵的就是

android:progressDrawable="@drawable/seekbar_style"
android:thumb="@drawable/thumb"

怎麼去定義呢？ 
看下面的代碼： 
seekbar_style.xml

<?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="10dip" />
         <gradient
             android:startColor="#ffffffff"
             android:centerColor="#ff000000"
             android:endColor="#ff808A87"
             android:centerY="0.45"
             android:angle="270"/>
      </shape>
   </item>

   <item android:id="@android:id/progress">
       <clip>
          <shape>
              <corners android:radius="10dip" />
              <gradient
                  android:startColor="#ffffffff"
                  android:centerColor="#ffFFFF00"
                  android:endColor="#ffAABD00"
                  android:centerY="0.45"
                  android:angle="270"/>
          </shape>
       </clip>
   </item>
 </layer-list>

thumb.xml

<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- 按下狀態 -->
    <item
        android:state_pressed="true"
        android:drawable="@drawable/xxxxxxxxxx" />

    <!-- 普通無焦點狀態 -->
    <item
        android:state_focused="false"
        android:state_pressed="false"
        android:drawable="@drawable/xxxxxxx" />

上面的xxxxxxx是圖片
</selector>

OK，問題解決！嘿嘿！
