我试图让我的应用程序添加提醒用户的日历。 该代码将搜索title
和start date
,以检查事件的日历已经存在添加它(以免有重复)前。 我的问题是:如果我从日历中手动删除该事件(使用日历),该事件从日历(我看我所有的日历并不能看到它在日历应用程序),但不会从数据库中消失。 我不明白的一件事是,我试图以编程方式删除的事件,但他们仍然不会被删除。
这里是我的代码片段:
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);
}
为什么事件仍然存在从日历应用程序删除它们后为什么我不能够,甚至编程方式删除呢?
更新问题是唯一的,如果我使用calendar_id=1
的插入和删除。 其他calendar_id
的工作的罚款。
更新2我测试了三星Galaxy S1的代码,它工作正常。 这似乎是在三星Galaxy S3的问题(在那里我有我的问题,我认为这是在S-规划者应用程序中的错误)
