計劃通知觸發每當我打開應用程序

Question

我正在構建一個應用程序觸發在11:30 IST通知..我已測試它的工作，但11:30後每當我打開我的應用程序它發出通知...

我不知道爲什麼，我覺得應該是在條件時檢查一些錯誤......

我想按時一天，第二天觸發通知只有一次......然後... :)

請先解決此問題 在此先感謝

**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;

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++; 

} 

}

經歷了這麼多茶葉和咖啡我編寫自己的答案...

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{ 

    } 

我剛纔比較系統時間time..if notifcation時間通知小於等於系統時間的真實reciever將work..but如果沒有，那麼什麼都不會發生......

BTW感謝幫助@tiny和@Mahesh

Answer 2

Intent intent1 = new Intent(MainActivity.this, AlarmReciever.class); 
intent1 .setAction("ilove"); 


public void onReceive(Context context, Intent intent) { 
if(!"ilove" .equalsIgnoreCase(getAction()))log.e("test",intent.getAction()); 
} 


<receiver android:name="com.android.app.AlaramReceiver" android:exported="false"> 
<intent-filter> 
<action android:name="ilove" /> 
</intent-filter> 
</receiver>
