Android日历活动

Question

我只是在使用日历内容提供程序进行操作,现在我无法显示特定日期的事件.

我知道<2.1版本和2.2版本的事件URI,如下所示:

eventsUri = Uri.parse("content://calendar/events");    // < Android 2.1 version

eventsUri = Uri.parse("content://com.android.calendar/events");  // For Android Froyo 2.2 and later version

我的怀疑是:

1. 我如何获取所有事件？
2. 如何获取特定日期的事件？

所以,有关日历知识的人请帮助我并分享您对此的了解.

感谢名单

Answer 1

这些例子适用于<= 2.1版本;

第一; 找出存在哪些日历

Cursor cursor = cr.query(Uri.parse("content://calendar/calendars"), new String[]{ "_id",  "displayname" }, null, null, null);
cursor.moveToFirst();
String[] CalNames = new String[cursor.getCount()];
int[] CalIds = new int[cursor.getCount()];
for (int i = 0; i < CalNames.length; i++) {
    CalIds[i] = cursor.getInt(0);
    CalNames[i] = cursor.getString(1);
    cursor.moveToNext();
}
cursor.close();

通过指定范围来获取所有事件和特定事件
ContentResolver contentResolver = getContentResolver();

Uri.Builder builder = Uri.parse(getCalendarUriBase() + "/instances/when").buildUpon();
        long now = new Date().getTime();
        ContentUris.appendId(builder, now - DateUtils.MILLIS_PER_DAY*10000);
        ContentUris.appendId(builder, now + DateUtils.MILLIS_PER_DAY * 10000);

然后假设您希望从ID = 1的日历中记录事件ID

Cursor eventCursor = contentResolver.query(builder.build(),
                new String[] { "event_id"}, "Calendars._id=" + 1,
                null, "startDay ASC, startMinute ASC"); 
        // For a full list of available columns see http://tinyurl.com/yfbg76w
        while (eventCursor.moveToNext()) {
            String uid2 = eventCursor.getString(0);
            Log.v("eventID : ", uid2);

        }
