每次我打开应用程序时都会触发预定的通知 [英] Scheduled Notifications Triggers Every Time I Open App

问题描述

我正在构建一个应用程序，它会在 IST 11:30 触发通知......我已经测试了它的工作原理，但是在 11:30 之后每当我打开我的应用程序它都会发出通知......

I am building an app which triggers a notification at 11:30 IST..I have Tested It Its Working But After 11:30 Whenever i open my app it issues a notification...

我不知道为什么我认为在时间检查中应该是条件错误...

i don't know why i think it should be some error in condition in time checking...

我希望每天只按时触发一次通知...然后第二天...:)

i want notification to be triggered on time only once in a day...and then the next day...:)

请解决这个问题提前致谢

please resolve this thanks in advance

**MainActivity.java**

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
spinner = (ProgressBar)findViewById(R.id.progressBar);
spinner.setVisibility(View.GONE);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 11);
calendar.set(Calendar.MINUTE, 30);
calendar.set(Calendar.SECOND, 00);
Intent intent1 = new Intent(MainActivity.this, AlarmReciever.class);
PendingIntent pendingIntent   = PendingIntent.getBroadcast(MainActivity.this,0,intent1, PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am = (AlarmManager) MainActivity.this.getSystemService(MainActivity.this.ALARM_SERVICE);
    am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
}


**AlarmReciever.java**

package com.alivestats.alivestats;

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.support.v4.app.NotificationCompat;
public class AlarmReciever extends BroadcastReceiver{

@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    int MID = 1;

    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Intent notificationIntent = new Intent(context, MainActivity.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
            notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);


    Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(
            context).setSmallIcon(R.drawable.background)
            .setContentTitle("title")
            .setContentText("description").setSound(alarmSound)
            .setAutoCancel(true).setWhen(when)
            .setContentIntent(pendingIntent)
            .setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
    notificationManager.notify(MID, mNotifyBuilder.build());
    MID++;

}

}

推荐答案

在喝了这么多茶和咖啡之后，我自己编写了答案...

After So Much Of Tea and Coffee i coded the answer myself...

long t = System.currentTimeMillis();
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 11);
calendar.set(Calendar.MINUTE, 30);
calendar.set(Calendar.SECOND, 00);
if (t <= calendar.getTimeInMillis()) {
        //calendar.add(Calendar.DATE, 6); //add 6 days.
        Intent intent1 = new Intent(MainActivity.this, AlarmReciever.class);
        intent1.setAction("NOTE");
        PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, intent1, PendingIntent.FLAG_UPDATE_CURRENT);
        AlarmManager am = (AlarmManager) MainActivity.this.getSystemService(MainActivity.this.ALARM_SERVICE);
        am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
        //am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
    }

    else{

    }

我刚刚将系统时间与通知时间进行了比较..如果通知时间小于等于系统时间，则它的真实性和接收器将工作..但如果不是那么什么都不会发生......

i have just compared system time to the notification time..if notifcation time is less than equal to system time its true and reciever will work..but if not then nothing will happen...
