在当天获取Android 4.0+上的所有日历活动

已经有相当一段时间一直在寻找我的问题的答案。我想做的事情：从当天的所有日历中获取所有事件在当天获取Android 4.0+上的所有日历活动

我能够在ICS之前的设备（2.2至3.2 Android版本）上没有任何问题。在Android 4.0+上，自推出新日历API以来，我一直在相当成功地处理它。那么，在我测试其他设备之前，我就是这么想的。有时我的代码工作，有时不会。重复事件不会显示在某些设备或其他设备上，所有事件都会显示（不仅仅是当天的事件）。

我认为这个问题是从一个代码行，但我找不到如何正确地做到这一点：

cursor = contentResolver.query(CalendarContract.Events.CONTENT_URI, COLS, "("+CalendarContract.Events.DTSTART+">"+now+" and "+CalendarContract.Events.DTEND+"<"+endOfDay.getTimeInMillis()+") or (("+CalendarContract.Events.ALL_DAY+"=1) and "+"("+CalendarContract.Events.DTSTART+">="+timeAllDay.getTimeInMillis()+") and "+"("+CalendarContract.Events.DTEND+"<="+endTimeAllDay.getTimeInMillis()+"))", null, null);

下面是我根据上述行创建的所有类：

public class ICSCalendar extends AsyncTask<Intent, String, Intent> 
    { 
     private static final String[] COLS = new String[] {CalendarContract.Events.TITLE, CalendarContract.Events.DTSTART, CalendarContract.Events.DTEND, CalendarContract.Events.ALL_DAY}; 

@Override 
protected Intent doInBackground(Intent... params) 
{ 
    ContentResolver contentResolver = Alert.mContext.getContentResolver(); 
    Cursor cursor = null; 

    try 
    { 
     long now = new Date().getTime(); 
     Calendar endOfDay = Calendar.getInstance(); 
     endOfDay.set(Calendar.HOUR_OF_DAY, 23); 
     endOfDay.set(Calendar.MINUTE, 59); 
     endOfDay.set(Calendar.SECOND, 59); 

     Calendar timeAllDay = Calendar.getInstance(); 
     timeAllDay.set(Calendar.HOUR_OF_DAY, 0); 
     timeAllDay.set(Calendar.MINUTE, 0); 
     timeAllDay.set(Calendar.SECOND, 0); 

     Calendar endTimeAllDay = Calendar.getInstance(); 
     endTimeAllDay.add(Calendar.DAY_OF_MONTH, 1); 
     endTimeAllDay.set(Calendar.HOUR_OF_DAY, 2); 
     endTimeAllDay.set(Calendar.MINUTE, 0); 
     endTimeAllDay.set(Calendar.SECOND, 1); 

     cursor = contentResolver.query(CalendarContract.Events.CONTENT_URI, COLS, "("+CalendarContract.Events.DTSTART+">"+now+" and "+CalendarContract.Events.DTEND+"<"+endOfDay.getTimeInMillis()+") or (("+CalendarContract.Events.ALL_DAY+"=1) and "+"("+CalendarContract.Events.DTSTART+">="+timeAllDay.getTimeInMillis()+") and "+"("+CalendarContract.Events.DTEND+"<="+endTimeAllDay.getTimeInMillis()+"))", null, null); 

     Intent calendarData = new Intent(Alerts.CALENDAR_UI_DATA); 
     int nb_events = 0; 

     while(cursor.moveToNext()) 
     { 
      nb_events++; 

      final String title = cursor.getString(0); 
      final Date begin = new Date(cursor.getLong(1)); 
      final Boolean allDay = !cursor.getString(3).equals("0"); 

      calendarData.putExtra("event_"+nb_events, (String) title); 
      calendarData.putExtra("all_day_event_"+nb_events, (Boolean) allDay); 

      Calendar beginEvent = Calendar.getInstance(); 
      beginEvent.setTimeInMillis(cursor.getLong(1)); 
      String format = Alerts.get24HourMode(Alert.mContext) ? "kk:mm": "h:mm"; 
      CharSequence newTime = DateFormat.format(format, beginEvent); 
      if(format == "h:mm") 
      { 
       if((beginEvent.get(Calendar.AM_PM) == 0)) 
       { 
        newTime = newTime + " A.M"; 
       } 
       else 
       { 
        newTime = newTime + " P.M"; 
       } 
      } 

      if(!allDay) 
      { 
       calendarData.putExtra("date_event_"+nb_events, newTime); 
      } 
      else 
      { 
       calendarData.putExtra("date_event_"+nb_events, Alert.mContext.getString(R.string.tts_whole_day_calendar_event)); 
      } 
     } 

     calendarData.putExtra("nb_events", nb_events); 

     return calendarData; 
    } 
    catch(Exception e) 
    { 
     Log.d("DEBUG", ""+e); 
     return null; 
    } 
} 

@Override 
protected void onPostExecute(Intent result) 
{ 
    // TODO Auto-generated method stub 
    super.onPostExecute(result); 

    try 
    { 
     Alert.mContext.sendBroadcast(result); 
    } 
    catch(NullPointerException e){} 
} 

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

@Override 
protected void onProgressUpdate(String... values) 
{ 
    // TODO Auto-generated method stub 
    super.onProgressUpdate(values); 
}

}

任何人有如何从所有日历的所有事件当天为Android 4.0以上版本的想法？感谢所有您的帮助:)

为了得到经常性事件，你需要的情况下表，查看更多详情here

这并不容易，因为它似乎我怕
