Android的 - 设置通知永远不会消失

问题描述：

我有这样的code，它的伟大工程：

I have this code that works great:

Notification n = builder.build();
n.flags = Notification.FLAG_NO_CLEAR;

但是，当我重新启动手机，通知消失。有没有做到这一点的标志？

But when I restart the phone, the notification goes away. Is there any flag that make that happen?

答

如果您想打印通知时，该装置启动时，您可以创建在系统启动完毕时调用，这个接收器，首先创建一个接收器，

If you want to print notification when the device boots up, you can create a receiver that is invoked when the system boot is completed, for this, first create a receiver,

public class MyReciever extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) 
{
        Log.d("BOOT COMPLETE","SERVICE CALLED>>>>>>>>>>>>");
        //use your code here to print notifications

    }
}

在完成系统启动该接收机被调用。您也可以从接收机的onReceive方法调用服务来打印通知。

This receiver is invoked when the system boot is completed. You can also call a service from the onReceive method of receiver to print the notification.

另外你必须在你的manifest文件定义以下规律，

Also you must define the following regularities in your manifest file,

首先定义权限获取BOOT_COMPLETION意图，

First define permission for getting BOOT_COMPLETION intent,

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

然后还可以定义你的接收器，

Then define your receiver also,

 <receiver android:name=".MyReciever" 
             android:enabled="true" 
             android:exported="false">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
            </intent-filter>
        </receiver>
