如何显示每个48小时后，Android通知？ [英] How to show android notification after every 48hours?

问题描述

我试过以下code，对于它是工作的罚款Android通知，但它给我通知弹出，当我开始我的Andr​​oid应用程序。

  

我想告诉每一个48小时后通知，我该怎么办呢？

什么样的​​变化，我需要做为了这个工作？

通知code

 意图notificationIntent =新意图（MainActivity.this，Activity.class）;
        的PendingIntent contentIntent = PendingIntent.getActivity（MainActivity.this，0，notificationIntent，0）;         NotificationManager notificationManager =（NotificationManager）MainActivity.this
                    .getSystemService（Context.NOTIFICATION_SERVICE）;         通知的NotI =新NotificationCompat.Builder（MainActivity.this）
                            .setSmallIcon（R.drawable.ic_launcher）
                            .setTicker（股票信息）                            .setWhen（System.currentTimeMillis的（））
                            .setContentTitle（HELLO）
                            .setContentText（请检查我们更新报）
                            .setContentIntent（co​​ntentIntent）
                            //最多三个动作按钮可以添加
                            .setAutoCancel（真）.build（）;
        INT notifyID = 0;
        notificationManager.notify（notifyID，NotI位）;
 

解决方案

下面是一些接近您需要在您的主要活动内容：

 意图notificationIntent =新意图（背景下，ShowNotification.class）;
    的PendingIntent contentIntent = PendingIntent.getService（上下文，0，notificationIntent，
                                                           PendingIntent.FLAG_CANCEL_CURRENT）;    AlarmManager AM =（AlarmManager）getSystemService（Context.ALARM_SERVICE）;
    am.cancel（contentIntent）;
    am.setRepeating（AlarmManager.RTC_WAKEUP，System.currentTimeMillis的（）
            + AlarmManager.INTERVAL_DAY * 2，AlarmManager.INTERVAL_DAY * 2，contentIntent）;
 

然后，在名为ShowNotification.java另一个文件，添加如下（假设你的主要活动被命名为MainActivity）：

 进口android.app.Notification;
进口android.app.NotificationManager;
进口android.app.PendingIntent;
进口android.app.Service;
进口android.content.Context;
进口android.content.Intent;
进口android.os.IBinder;
进口android.support.v4.app.NotificationCompat;
进口android.util.Log;公共类ShowNotification延伸服务{    私人最终静态字符串变量=ShowNotification;    @覆盖
    公共无效的onCreate（）{
        super.onCreate（）;        意图mainIntent =新意图（这一点，MainActivity.class）;        notificationManager notificationManager
            =（NotificationManager）this.getSystemService（Context.NOTIFICATION_SERVICE）;        通知的NotI =新NotificationCompat.Builder（本）
            .setAutoCancel（真）
            .setContentIntent（PendingIntent.getActivity（这一点，0，mainIntent，
                              PendingIntent.FLAG_UPDATE_CURRENT））
            .setContentTitle（HELLO+ System.currentTimeMillis的（））
            .setContentText（请检查我们更新报）
            .setDefaults（Notification.DEFAULT_ALL）
            .setSmallIcon（R.drawable.ic_launcher）
            .setTicker（股票信息）
            .setWhen（System.currentTimeMillis的（））
            。建立（）;        notificationManager.notify（0，NotI位）;        Log.i（TAG，通知创造）;
    }    @覆盖
    公众的IBinder onBind（意向意图）{
        // TODO自动生成方法存根
        返回null;
    }
}
 

I tried following code for android notification which is working fine but it is giving me notification popup when I start my android app.

I want to show an notification after every 48hours, how can I do it?

What changes do I need to make in order for this to work?

Notification code

 Intent notificationIntent = new Intent(MainActivity.this, Activity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(MainActivity.this, 0, notificationIntent, 0);

         NotificationManager notificationManager = (NotificationManager) MainActivity.this
                    .getSystemService(Context.NOTIFICATION_SERVICE);

         Notification noti = new NotificationCompat.Builder(MainActivity.this)
                            .setSmallIcon(R.drawable.ic_launcher)
                            .setTicker("ticker message")

                            .setWhen(System.currentTimeMillis())
                            .setContentTitle("HELLO")
                            .setContentText("PLEASE CHECK WE HAVE UPDATED NEWS")
                            .setContentIntent(contentIntent)
                            //At most three action buttons can be added
                            .setAutoCancel(true).build();
        int notifyID =0;
        notificationManager.notify(notifyID, noti);

解决方案

Here's something close to what you need in your main activity:

    Intent notificationIntent = new Intent(context, ShowNotification.class);
    PendingIntent contentIntent = PendingIntent.getService(context, 0, notificationIntent,
                                                           PendingIntent.FLAG_CANCEL_CURRENT);

    AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    am.cancel(contentIntent);
    am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
            + AlarmManager.INTERVAL_DAY * 2, AlarmManager.INTERVAL_DAY * 2, contentIntent);

Then, in another file named ShowNotification.java, add the following (assuming your main activity is named MainActivity):

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

public class ShowNotification extends Service {

    private final static String TAG = "ShowNotification";

    @Override
    public void onCreate() {
        super.onCreate();

        Intent mainIntent = new Intent(this, MainActivity.class);

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

        Notification noti = new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentIntent(PendingIntent.getActivity(this, 0, mainIntent,
                              PendingIntent.FLAG_UPDATE_CURRENT))
            .setContentTitle("HELLO " + System.currentTimeMillis())
            .setContentText("PLEASE CHECK WE HAVE UPDATED NEWS")
            .setDefaults(Notification.DEFAULT_ALL)
            .setSmallIcon(R.drawable.ic_launcher)
            .setTicker("ticker message")
            .setWhen(System.currentTimeMillis())
            .build();

        notificationManager.notify(0, noti);

        Log.i(TAG, "Notification created");
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }
}
