我试图让我的应用程序向用户的日历添加提醒。代码搜索标题和开始日期,以便在添加之前检查日历中是否已经存在该事件(以便不具有重复项)。我的问题是:如果我手动从日历中删除事件(使用日历),事件将从日历中消失(我正在查看我的日历,在日历应用程序中无法看到它),而不是从数据库中查看。我不明白的另一件事是我试图以编程方式删除事件,但仍然没有删除。 这是我的代码片段: Cursor cur = null; ContentResolver cr = getContentResolver(); String calUriString = "content://com.android.calendar/events"; Uri cal=Uri.parse(calUriString); String[] EVENT_PROJECTION=new String[]{"calendar_id","title","dtstart","_id"}; String selection = "((" + "calendar_id" + " = 1) AND (" + "title" + " LIKE '"+name+"') AND (" + "dtstart" + " = "+String.valueOf(c.getTimeInMillis())+"))"; cur = cr.query(cal, EVENT_PROJECTION, selection, null, null); boolean found=false; if(cur!=null) if(cur.moveToFirst()){ DatabaseUtils.dumpCursor(cur);/*Just to view my results (which always include the deleted events)*/ do{ if(cur.getString(1).equals(name)){ /*I use this part to try to remove the events manually*/ Uri eventUri =ContentUris.withAppendedId(cal, Long.valueOf(cur.getString(3))); String reminderUriString = "content://com.android.calendar/reminders"; Uri remUri =Uri.parse(reminderUriString); cr.delete(remUri, "event_id="+cur.getString(3), null); cr.delete(eventUri, null, null); /*It is not working also*/ Toast.makeText(getApplicationContext(), "Event already exists in Calendar", Toast.LENGTH_LONG).show(); found=true; //break; } }while(cur.moveToNext()); } cur.close(); if(found){ /*Event is found even if I remove it from the Calendar manually and even if I remove it programmatically using cr.delete()*/ } else{ values.put("calendar_id",1); /*I am using the same Calendar that I query, or is this wrong*/ values.put("title", name); /*More values are added*/ Uri calendarUri = cr.insert(cal, values); long eventID = Long.parseLong(calendarUri.getLastPathSegment()); String reminderUriString = "content://com.android.calendar/reminders"; ContentValues reminderValues = new ContentValues(); reminderValues.put("event_id", eventID); reminderValues.put("minutes", 5); reminderValues.put("method", 1); Uri reminderUri = getApplicationContext().getContentResolver().insert(Uri.parse(reminderUriString), reminderValues); } 为什么从日历应用程序中删除它们后仍然存在这些事件,为什么我甚至无法通过编程方式将其删除? 更新 问题仅在我使用calendar_id = 1插入和删除。其他calendar_ids工作正常。 更新2 我测试了三星Galaxy S1的代码,它的工作正常。这似乎是三星Galaxy S3的一个问题(我有我的问题,我认为这是S-planner应用程序中的一个错误) |
