Android下修改SeekBar样式

SeekBar配置文件：

<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 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：

<?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

<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：

<?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>
