推荐答案

您需要侦听<一个href=\"http://developer.android.com/reference/android/content/Intent.html#ACTION_MEDIA_REMOVED\">ACTION_MEDIA_REMOVED和<一个href=\"http://developer.android.com/reference/android/content/Intent.html#ACTION_MEDIA_MOUNTED\">ACTION_MEDIA_MOUNTED.创建一个接收器和监听这个动作。

You need to listen for ACTION_MEDIA_REMOVED and ACTION_MEDIA_MOUNTED. Create a receiver and listen for this action.

编辑：

在你的manifest文件添加此

In your manifest file add this

<receiver android:name=".MyReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.MEDIA_REMOVED" />
        <action android:name="android.intent.action.MEDIA_MOUNTED" />
    </intent-filter>
</receiver>

然后创建一个类MyReceiver这将延长广播接收器，然后捕获这些行动和执行您想要做什么。

then create a class MyReceiver which will extend BroadcastReceiver and then catch these actions and perform what you want to do.
