SeekBar自定义

代码如下

Java代码

<SeekBarandroid: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/>

<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 />

其实最最关键的就是

Java代码

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

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

怎么去定义呢？
看下面的代码：
seekbar_style.xml

Java代码

<?xmlversion="1.0"encoding="UTF-8"?>
<layer-listxmlns:android="http://schemas.android.com/apk/res/android">
<itemandroid:id="@android:id/background">
<shape>
<cornersandroid:radius="10dip"/>
<gradient
android:startColor="#ffffffff"
android:centerColor="#ff000000"
android:endColor="#ff808A87"
android:centerY="0.45"
android:angle="270"/>
</shape>
</item>
<itemandroid:id="@android:id/progress">
<clip>
<shape>
<cornersandroid:radius="10dip"/>
<gradient
android:startColor="#ffffffff"
android:centerColor="#ffFFFF00"
android:endColor="#ffAABD00"
android:centerY="0.45"
android:angle="270"/>
</shape>
</clip>
</item>
</layer-list>

<?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

Java代码

<?xmlversion="1.0"encoding="UTF-8"?>
<selectorxmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"
android:drawable="@drawable/xxxxxxxxxx"/>
<item
android:state_focused="false"
android:state_pressed="false"
android:drawable="@drawable/xxxxxxx"/>
上面的xxxxxxx是图片
</selector>

<?xml version="1.0" encoding="UTF-8"?>  <selector xmlns:android="http://schemas.android.com/apk/res/android">            <!-- 按下状态 -->     <item            android:state_pressed="true"            android:drawable="@drawable/xxxxxxxxxx" />                    <!-- 普通无焦点状态 -->     <item            android:state_focused="false"            android:state_pressed="false"          android:drawable="@drawable/xxxxxxx" />上面的xxxxxxx是图片</selector>

OK，问题解决！嘿嘿！
