android animation 使用自定义 ProgressDialog

1、建立myprogress.xml在 res/anim中
<?xml version="1.0" encoding="UTF-8"?>
<animation-list android:oneshot="false"
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:duration="500" android:drawable="@drawable/progress1" />
<item android:duration="500" android:drawable="@drawable/progress2" />
<item android:duration="500" android:drawable="@drawable/progress3" />
<item android:duration="500" android:drawable="@drawable/progress4" />
</animation-list>


2、在style.xml中
 
<style name="oaprogress" parent="@android:style/Widget.ProgressBar">
<item name="android:indeterminateDrawable">@anim/myprogress</item>
<item name="android:backgroundDimEnabled">true</item>
</style>


3、在layout中
<ProgressBar 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
style="@style/oaprogress"
/>
