1.使用

            <SeekBar
                android:id="@+id/videoSeekBar"
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="wrap_content"
                android:layout_gravity="center_vertical"
                android:progressDrawable="@drawable/player_setting_bright_progressbar"
                android:thumb="@drawable/player_settings_bright_thumb" />

2.属性介绍

android:progressDrawable //进度条样式

android:thumb //拖动图标样式

3.进度条样式修改

新建player_setting_bright_progressbar.xml文件

<?xml version="1.0" encoding="utf-8"?>
<layer-list
  xmlns:android="http://schemas.android.com/apk/res/android">
   <!-- 背景图 -->  
    <item android:id="@android:id/background" android:drawable="@drawable/setting_bright_seekbar_background" />
  <!-- 第二进度条的背景色 -->
    <item android:id="@android:id/secondaryProgress"  >
        <scale android:drawable="@color/seekbar_second" android:scaleWidth="100%" />
    </item>
    <!-- 可拖动的进度条颜色 -->  
    <item android:id="@android:id/progress">
        <scale android:drawable="@drawable/setting_bright_seekbar_progress" android:scaleWidth="100%" />
    </item>
</layer-list>

4.修改拖动的图标

新建player_settings_bright_thumb.xml文件

<?xml version="1.0" encoding="utf-8"?>  
<selector  
  xmlns:android="http://schemas.android.com/apk/res/android">  
    <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/seekbar_thumb_normal" />  
    <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/seekbar_thumb_pressed" />  
    <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/seekbar_thumb_pressed" />  
    <item android:drawable="@drawable/seekbar_thumb_normal" />  
</selector>
