每次我打開我的應用程序時都會顯示通知

Question

我有一個應用程序，我希望每天早晨8:30在用戶中向用戶顯示通知。一切工作正常。除了一件事。 每次打開應用程序時都會顯示通知。我搜索了很多這個bug，但我不能糾正這個bug ..

這是我的應用程序的啓動類。

public class xyz extends Activity { 




/** Called when the activity is first created. */ 

@SuppressWarnings("deprecation") 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 




    Intent myIntent = new Intent(xyz.this , NotificationService.class);  
    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE); 
    PendingIntent pendingIntent = PendingIntent.getService(xyz.this, 0, myIntent, 0); 
    Calendar calendar = Calendar.getInstance(); 
    calendar.set(Calendar.HOUR_OF_DAY, 8); 
    calendar.set(Calendar.MINUTE, 30); 
    calendar.set(Calendar.SECOND, 00); 
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24*60*60*1000 , pendingIntent); 


     final ConnectivityManager conMgr = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); 
     final NetworkInfo activeNetwork = conMgr.getActiveNetworkInfo(); 

     if (activeNetwork != null && activeNetwork.isConnected()) { 
      //notify user you are online 
      Thread Timer = new Thread(){    
        public void run() 
        { 
         try{     

          sleep(3000); 

         }catch(Exception e){ 

        e.printStackTrace(); 

        } 

        finally{ 


        Intent openScreen = new Intent(xyz.this , Selection_Page.class); 

        startActivity(openScreen); 

      }  

        }  

        }; 

         Timer.start(); 
     } 
     else { // something in else} }} 

，這是我通知服務類。

public class NotificationService extends Service { 

private NotificationManager mManager; 

@Override 
public IBinder onBind(Intent arg0) { 
    // TODO Auto-generated method stub 
    return null; 
} 

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

@Override 
public void onStart(Intent intent, int startId) { 
    //super.onStart(intent, startId); 
    // Getting Notification Service 
    mManager = (NotificationManager) this.getApplicationContext() 
      .getSystemService(
        this.getApplicationContext().NOTIFICATION_SERVICE); 
    /* 
    * When the user taps the notification we have to show the Home Screen 
    * of our App, this job can be done with the help of the following 
    * Intent. 
    */ 
    Uri NOtification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
    Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), NOtification); 
    r.play(); 


    Intent intent1 = new Intent(this.getApplicationContext(), Selection_Page.class); 

    Notification notification = new Notification(R.drawable.brand_icon, 
      "See my app for you", System.currentTimeMillis()); 

    intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP 
      | Intent.FLAG_ACTIVITY_CLEAR_TOP); 

    PendingIntent pendingNotificationIntent = PendingIntent.getActivity(
      this.getApplicationContext(), 0, intent1, 
      PendingIntent.FLAG_UPDATE_CURRENT); 

    notification.flags |= Notification.FLAG_AUTO_CANCEL; 

    notification.setLatestEventInfo(this.getApplicationContext(), 
      "aaa", "See my app for you", 
      pendingNotificationIntent); 

    mManager.notify(0, notification); 
} 

@Override 
public void onDestroy() { 
    // TODO Auto-generated method stub 
    super.onDestroy(); 
}} 

請告訴我，我錯過了東西..

在此先感謝..

有一件事我注意到，您設置8:30今天警告這是在過去，因爲你不會改變日曆的日常價值。所以請嘗試將日期值更改爲today + 1，然後重試。以下是更新後的代碼與在day值變化：

Intent myIntent = new Intent(xyz.this , NotificationService.class);  
    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE); 
    PendingIntent pendingIntent = PendingIntent.getService(xyz.this, 0, myIntent, 0); 
    Calendar calendar = Calendar.getInstance(); 
    calender.setTime(System.currentTimeMillis()); 
    calendar.set(Calendar.DAY_OF_MONTH, calender.get(Calender.DAY_OF_MONTH)+1); 
    calendar.set(Calendar.HOUR_OF_DAY, 8); 
    calendar.set(Calendar.MINUTE, 30); 
    calendar.set(Calendar.SECOND, 00); 
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24*60*60*1000 , pendingIntent); 

請測試它讓我知道它是如何工作...

你需要在這裏介紹一個檢查點。只需將系統時間與要觸發的通知時間進行比較，如果系統時間大於通知時間，則不執行任何操作。否則會通知。

修改您的代碼如下。它會工作。

Intent myIntent = new Intent(xyz.this , NotificationService.class);  
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE); 
PendingIntent pendingIntent = PendingIntent.getService(xyz.this, 0, myIntent, 0); 
long systemTime = System.currentTimeMillis(); 
Calendar calendar = Calendar.getInstance(); 
calendar.set(Calendar.HOUR_OF_DAY, 8); 
calendar.set(Calendar.MINUTE, 30); 
calendar.set(Calendar.SECOND, 00); 
if(systemTime <= calendar.getTimeInMillis()) { 
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24*60*60*1000 , pendingIntent); 
} 
else{ 
//do nothing 
}
