android - 如何整合日历事件

Question

我需要在我的应用程序中集成谷歌日历事件（CRUD 操作）。首先，我想到了使用内容提供程序从本地日历应用程序访问事件数据。但我发现只有 ICS(api 14) 支持日历提供程序。1）有没有办法在较低版本中访问日历提供程序？2）是否可以在android 中使用谷歌日历api（https://developers.google.com/google-apps/calendar/ ）？

Answer 1

要获取日历事件，下面的代码正在运行：

private void getCalenderEvents() {
        Cursor cursor = context.getContentResolver().query(Uri.parse("content://com.android.calendar/events"),
                new String[] { "calendar_id", "title", "description", "dtstart", "dtend", "eventLocation" }, null, null, null);
        cursor.moveToFirst();
        // fetching calendars name
        String CNames[] = new String[cursor.getCount()];

        for (int i = 0; i < CNames.length; i++) {

            rowDataEvents = new HashMap<String, String>();

            String eventTitle = cursor.getString(1);
            String eventStartDate = cursor.getString(3);
            String eventEndDate = cursor.getString(4);
            String eventDescription = cursor.getString(2);
            String eventLocation = cursor.getString(5);
            cursor.moveToNext();

        }
        cursor.close();
    }
