在nadroid重新啓動時清除報警

Question

我想在7天后發佈數據重複。爲此，我使用Alarm Manager的setRepeat方法。當手機重新啓動時，鬧鐘將被清除。我使用啓動接收器並重新設置鬧鐘。

但是如果手機在第6天重新啓動並且鬧鐘再次設置，則鬧鐘將在第6 + 7天響鈴，而不是在第7天應該響起。 有沒有辦法解決這個問題？

對不起，我英文很差。 請幫助

Answer 1

當設置鬧鐘時，將觸發時間保存在共享偏好設置中。並且在啓動接收器上再次設置鬧鐘，但在這種情況下，觸發時間來自共享偏好設置。

在AndroidManifest.xml中

<receiver android:name="com.Company.PackageName.BootCompletedReceiver" > 
      <intent-filter> 
       <action android:name="android.intent.action.BOOT_COMPLETED" /> 
      </intent-filter> 
     </receiver> 

在你com.Company.PackageName.BootCompletedReceiver類

public class BootCompletedReceiver extends BroadcastReceiver 
{ 
    private Context mContext; 
    private G9SharedPreferences oSharedPreferences; 
    private AlarmManager amSchedules; 

    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     this.mContext = context; 
     oSharedPreferences = new G9SharedPreferences(this.mContext); 
     try 
     { 
      vUpdateAlarmManager(); 
     } 
     catch (Exception e) 
     { 
      e.printStackTrace(); 
     } 
     finally 
     { 
      oSharedPreferences = null; 
      this.mContext = null; 
     } 
    } 

    @SuppressWarnings("deprecation") 
    public void vUpdateAlarmManager() 
    { 
     vCancelAlaramManager(); 
     Date dCurrentDate = new Date(oSharedPreferences.GetLongPreferences(G9Constant.BACKUP_TIME, 0));  
     if(dCurrentDate.getTime() < new Date().getTime()) 
     { 
      dCurrentDate.setDate(dCurrentDate.getDate() + 1); 
     } 
     vSetRepeatingAlarm(dCurrentDate); 
    } 

    public void vCancelAlaramManager() 
    { 
     Intent oIntent = new Intent(mContext, AlarmReceiver.class); 
     PendingIntent oPendingIntent = PendingIntent.getBroadcast(mContext, 0, oIntent, 0); 
     AlarmManager alarmManager = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE); 
     alarmManager.cancel(oPendingIntent); 
     oPendingIntent.cancel(); 
    } 

    public void vSetRepeatingAlarm(Date dScheduleTime) 
    { 
     amSchedules = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE); 
     Intent intent = new Intent(mContext, AlarmReceiver.class); 
     PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

     amSchedules.setRepeating(AlarmManager.RTC_WAKEUP, dScheduleTime.getTime(), AlarmManager.INTERVAL_DAY , pendingIntent); 
    } 
}
