android - 如何从日历中获取所有事件？

Question

您好，我可以使用此代码获取事件

cur = null;
    cr = getContentResolver();


    // Construct the query with the desired date range.
    Uri.Builder builder = Instances.CONTENT_URI.buildUpon();

    ContentUris.appendId(builder, 0);
    ContentUris.appendId(builder, endMillis);


    // Submit the query
    cur =  cr.query(builder.build(), 
        INSTANCE_PROJECTION, 
        null, 
        null, 
        null);

但是如您所见，我只能获得给定持续时间内的事件，但我需要所有事件(没有任何时间规范，不包括重复事件)这可能吗？如何 ？请帮助我。

cur =  cr.query(Uri.parse("content://com.android.calendar/events"), 
        INSTANCE_PROJECTION, 
        null, 
        null, 
        null);

它给出错误 java.lang.IllegalArgumentException:

试试这个代码...

public class Utility {

    public static ArrayList<String> nameOfEvent = new ArrayList<String>();
    public static ArrayList<String> startDates = new ArrayList<String>();
    public static ArrayList<String> endDates = new ArrayList<String>();
    public static ArrayList<String> descriptions = new ArrayList<String>();

    public static ArrayList<String> readCalendarEvent(Context context) {
        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()];

        // fetching calendars id
        nameOfEvent.clear();
        startDates.clear();
        endDates.clear();
        descriptions.clear();
        for (int i = 0; i < CNames.length; i++) {

            nameOfEvent.add(cursor.getString(1));
            startDates.add(getDate(Long.parseLong(cursor.getString(3))));
            endDates.add(getDate(Long.parseLong(cursor.getString(4))));
            descriptions.add(cursor.getString(2));
            CNames[i] = cursor.getString(1);
            cursor.moveToNext();

        }
        return nameOfEvent;
    }

    public static String getDate(long milliSeconds) {
        SimpleDateFormat formatter = new SimpleDateFormat(
                "dd/MM/yyyy hh:mm:ss a");
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(milliSeconds);
        return formatter.format(calendar.getTime());
    }
}
