android - 怎么重启手机后一直显示Notification图标？

Question

我正在使用以下代码将图标添加到通知状态，效果很好，即使我退出应用程序，它也会始终显示。

但是每次重启手机图标就消失了，请问怎样才能让手机重启后图标一直显示呢？

private void showNotification() {

    NotificationManager notificationManager = (NotificationManager)
    this.getSystemService(android.content.Context.NOTIFICATION_SERVICE);


    Notification notification = new Notification(R.drawable.smsforward,"My System", System.currentTimeMillis());


    notification.flags |= Notification.FLAG_ONGOING_EVENT; 
    notification.flags |= Notification.FLAG_NO_CLEAR;

    CharSequence contentTitle = "My System Title"; 
    CharSequence contentText = "My System Title content"; 

    Intent notificationIntent = new Intent(this, SMSMain.class); 

    PendingIntent contentItent = PendingIntent.getActivity(this, 0,
            notificationIntent, 0);

    notification.setLatestEventInfo(this, contentTitle, contentText,contentItent);

    notificationManager.notify(0, notification);
}

您需要在启动完成时收听，然后再次显示相同的通知。这是一个简单的例子。

在您的 list 文件中。

<receiver android:name="BootNotificationReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

并在您的代码中。

 public class BootNotificationReceiver extends BroadcastReceiver
    {
    public void onReceive(Context context, Intent intent) {

     // display notification again
     showNotification();// or whatever

      }
    }

快乐编码:)
