<item
android:id="@android:id/background"
android:drawable="@drawable/security_progress_bg">

<item
android:id="@android:id/secondaryProgress"
android:drawable="@drawable/security_progress">
</item>
<item //一定要写在item的属性位置，否则显示不对
android:id="@android:id/progress"
android:drawable="@drawable/security_progress">

</layer-list> c)背景图片   |
| 测试代码： new Thread() {
public void run() {
pb_scan_progress.setMax(100);
for (int i = 1; i <= 100; i++) {
pb_scan_progress.setProgress(i);
try {
Thread.sleep(30);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}.start();结果：  |
