我正在Android版本4中顯示日曆事件,它可以爲這樣的事件的標題和其他詳細信息給出數組列表,但無法顯示。
我收到錯誤爲日曆未找到。在特定日期獲取ICS android版本4的日曆事件
public void readCalendar1()
{
ContentResolver contentResolver = this.getContentResolver();
// Fetch a list of all calendars synced with the device, their display names and whether the
// user has them selected for display.
Cursor cursor;
cursor = contentResolver.query(CalendarContract.Calendars.CONTENT_URI, new String[]
{ CalendarContract.Calendars._ID, CalendarContract.Calendars.CALENDAR_DISPLAY_NAME },
null, null, CalendarContract.Calendars.CALENDAR_DISPLAY_NAME + " ASC");
HashSet<String> calendarIds1 = new HashSet<String>();
while (cursor.moveToNext())
{
final String _id = cursor.getString(0);
final String displayName = cursor.getString(1);
System.out.println("Id: " + _id + " Display Name: " + displayName);
calendarIds1.add(_id);
}
// For each calendar, display all the events from the previous week to the end of next week.
for (String id : calendarIds1)
{
Uri builder = CalendarContract.Events.CONTENT_URI;
System.out.println("str in read cal1 "+strconvert+"str2 in read cal1 "+strconvert1);
//strconvert and strconvert1 are string which have the particular dates
Cursor eventCursor = contentResolver.query(builder,
new String[] { CalendarContract.Events.TITLE, strconvert,
strconvert1, CalendarContract.Events.ALL_DAY,CalendarContract.Events.EVENT_LOCATION,
CalendarContract.Events.HAS_ALARM,CalendarContract.Events.DESCRIPTION},
"calendar_id=" + id,null,"dtstart ASC");
// For a full list of available columns see http://tinyurl.com/yfbg76w
int n=eventCursor.getCount();
System.out.println("No. of rows is="+n);
while(eventCursor.moveToNext())
{
title = eventCursor.getString(0);
begin = new Date(eventCursor.getLong(1));
end = new Date(eventCursor.getLong(2));
allDay = !eventCursor.getString(3).equals("0");
loc=eventCursor.getString(4);
hasalarm = !eventCursor.getString(5).equals("0");

titlestr.add(title);
sdatestr.add(begin.toString());

這兩個版本是它做工精細豆形軟糖中讀?獲取異常:android.database.sqlite.SQLiteException:沒有這樣的列:Calendars._id(code 1): –
是的,它是因爲你試圖讓一個colum沒有創建..請檢查你是否錯過了任何逗號或任何東西碼? –
錯誤消息說** Calendars._id **不存在。在JellyBean上測試它 –
