我在向Calendar添加条目时遇到问题.我尝试了很多测试,但没有成功.

源代码：

String calName;

String calId = null;

String[] projection = new String[] { "_id", "name" };

Uri calendars = Uri.parse("content://com.android.calendar/calendars");

Cursor managedCursor = managedQuery(calendars, projection, "selected=1", null, null);

ContentValues event = new ContentValues();

DateFormat date = new SimpleDateFormat("dd/MM/yyyy hh:mm");

long time = System.currentTimeMillis();

String StartTime = date.format(time);

String EndTime = "13/4/2011 15:30";

Log.d(TAG, "Value of timeStr: " + StartTime);

if (managedCursor.moveToFirst()) {

int nameColumn = managedCursor.getColumnIndex("name");

int idColumn = managedCursor.getColumnIndex("_id");

do{

calName = managedCursor.getString(nameColumn);

calId = managedCursor.getString(idColumn);

event.put("calendar_id", calId);

event.put("title", "Event Title");

event.put("description", "Description");

event.put("eventLocation", "New York");

event.put("dtstart", StartTime );

event.put("dtend", EndTime);

Uri eventsUri = Uri.parse("content://com.android.calendar/events");

Uri calUri = getContentResolver().insert(eventsUri, event);

}

while (managedCursor.moveToNext());

}

}

}

错误：
