如何知道Android手机会睡觉？ 请帮我一个示例代码。 谢谢你的阅读。

Answer 1

您需要为Intent.ACTION_SCREEN_OFF注册广播接收器

所以，创建broadcastreceiver

这是您处理screen_off意图的地方。

private BroadcastReceiver receiver = new BroadcastReceiver() {
public void onReceive(final Context context, final Intent intent) {

    /*
     * dispatch screen_off
         * to handler method
     */

    String iAction = intent.getAction();

    if (iAction.equals(Intent.ACTION_SCREEN_OFF))
    handleScreenAction(iAction);

}

};

现在注册接收器的过滤器。

static void registerReciever() {
    IntentFilter myFilter = new IntentFilter();
    // Catch screen off event
    myFilter.addAction(Intent.ACTION_SCREEN_OFF);
    registerReceiver(receiver, myFilter);
}
