重新啓動手機越來越多通知的

Question

我有簡單的提醒應用程序。我的應用程序的問題是，當我重新啓動手機或任何設備時，該應用程序開始拋出許多通知。 This是所有Java文件的源代碼。這是OnBootReceiver：

public class OnBootReceiver extends BroadcastReceiver { 

    private static final String TAG = ComponentInfo.class.getCanonicalName(); 

    @Override 
    public void onReceive(Context context, Intent intent) { 

     ReminderManager reminderMgr = new ReminderManager(context); 

     RemindersDbAdapter dbHelper = new RemindersDbAdapter(context); 
     dbHelper.open(); 

     Cursor cursor = dbHelper.fetchAllReminders(); 

     if(cursor != null) { 
      cursor.moveToFirst(); 

      int rowIdColumnIndex = cursor.getColumnIndex(RemindersDbAdapter.KEY_ROWID); 
      int dateTimeColumnIndex = cursor.getColumnIndex(RemindersDbAdapter.KEY_DATE_TIME); 

      while(cursor.isAfterLast() == false) { 

       Log.d(TAG, "Adding alarm from boot."); 
       Log.d(TAG, "Row Id Column Index - " + rowIdColumnIndex); 
       Log.d(TAG, "Date Time Column Index - " + dateTimeColumnIndex); 

       Long rowId = cursor.getLong(rowIdColumnIndex); 
       String dateTime = cursor.getString(dateTimeColumnIndex); 

       Calendar cal = Calendar.getInstance(); 
       SimpleDateFormat format = new SimpleDateFormat(ReminderEditActivity.DATE_TIME_FORMAT); 

       try { 
        java.util.Date date = format.parse(dateTime); 
        cal.setTime(date); 

        reminderMgr.setReminder(rowId, cal); 
       } catch (java.text.ParseException e) { 
        Log.e("OnBootReceiver", e.getMessage(), e); 
       } 

       cursor.moveToNext(); 
      } 
      cursor.close() ;  
     } 

     dbHelper.close(); 
    } 
} 

這是WakeReminderIntentService：

public abstract class WakeReminderIntentService extends IntentService { 
abstract void doReminderWork(Intent intent); 

    public static final String LOCK_NAME_STATIC="com.dummies.android.taskreminder.Static"; 
    private static PowerManager.WakeLock lockStatic=null; 

    public static void acquireStaticLock(Context context) { 
     getLock(context).acquire(); 
    } 

    synchronized private static PowerManager.WakeLock getLock(Context context) { 
     if (lockStatic==null) { 
      PowerManager mgr=(PowerManager)context.getSystemService(Context.POWER_SERVICE); 
      lockStatic=mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, 
                 LOCK_NAME_STATIC); 

      lockStatic.setReferenceCounted(true); 
     } 
     return(lockStatic); 
    } 

    public WakeReminderIntentService(String name) { 
     super(name); 
    } 

    @Override 
    final protected void onHandleIntent(Intent intent) { 
     try { 
      doReminderWork(intent); 
     } 
     finally { 
      //getLock(this).release(); 
     } 
    } 
} 

你能不能幫我取消通知的裝置的重新啓動後。在代碼中告訴在特定時間安排通知，但我很困惑爲什麼設備重新啓動後，我從應用程序獲得許多通知。有人能告訴我哪裏錯了嗎？

更新：

OnBootReceiver：

import java.text.SimpleDateFormat; 
import java.util.Calendar; 

import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.content.pm.ComponentInfo; 
import android.database.Cursor; 
import android.util.Log; 

public class OnBootReceiver extends BroadcastReceiver { 

    private static final String TAG = ComponentInfo.class.getCanonicalName(); 

    @Override 
    public void onReceive(Context context, Intent intent) { 

     ReminderManager reminderMgr = new ReminderManager(context); 

     RemindersDbAdapter dbHelper = new RemindersDbAdapter(context); 
     dbHelper.open(); 

     Cursor cursor = dbHelper.fetchAllReminders(); 

     if(cursor != null) { 
      cursor.moveToFirst(); 

      int rowIdColumnIndex = cursor.getColumnIndex(RemindersDbAdapter.KEY_ROWID); 
      int dateTimeColumnIndex = cursor.getColumnIndex(RemindersDbAdapter.KEY_DATE_TIME); 

      while(cursor.isAfterLast() == false) { 

       Log.d(TAG, "Adding alarm from boot."); 
       Log.d(TAG, "Row Id Column Index - " + rowIdColumnIndex); 
       Log.d(TAG, "Date Time Column Index - " + dateTimeColumnIndex); 

       Long rowId = cursor.getLong(rowIdColumnIndex); 
       String dateTime = cursor.getString(dateTimeColumnIndex); 

       Calendar cal = Calendar.getInstance(); 
       SimpleDateFormat format = new SimpleDateFormat(ReminderEditActivity.DATE_TIME_FORMAT); 

       try { 
        java.util.Date date = format.parse(dateTime); 
        cal.setTime(date); 

        reminderMgr.setReminder(rowId, cal); 
       } catch (java.text.ParseException e) { 
        Log.e("OnBootReceiver", e.getMessage(), e); 
       } 

       cursor.moveToNext(); 
      } 
      cursor.close() ;  
     } 

     dbHelper.close(); 
    } 
} 

setReminder（）方法：

public void setReminder(Long taskId, Calendar when) { 

    Intent i = new Intent(mContext, OnAlarmReceiver.class); 
    i.putExtra(RemindersDbAdapter.KEY_ROWID, (long)taskId); 

    PendingIntent pi = PendingIntent.getBroadcast(mContext, 0, i, PendingIntent.FLAG_ONE_SHOT); 

    mAlarmManager.set(AlarmManager.RTC_WAKEUP, when.getTimeInMillis(), pi); 
} 

Answer 1

Okei我已經在你的源代碼，擡頭一看，我認爲你應該取消您的清單這一行：

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

Answer 2

在ReminderEditActivity類saveState功能不保存時間格式的日期。相反，只需保存calendar.getTimeInMillis()即可。

例：

private void saveState() { 
    long id = mDbHelper.createReminder(title, body, mCalendar.getTimeInMillis()); 
} 

現在您的fetchAllReminder查詢，您可以添加：

例：

Calendar currentTime = Calendar.getInstance(); 
return mDb.query(DATABASE_TABLE, new String[] {KEY_ROWID, KEY_TITLE, KEY_BODY, KEY_DATE_TIME}, null, "reminder_date_time > " + currentTime.getTimeInMillis(), null, null, null);
