如何在android设备中获取设备日历事件列表？

我想在android设备上获取最后七天的日历事件？我是初学者，所以请告诉我一步一步的解决方案。。！仅获取和读取日历，不更新和删除。有人帮我吗？我在下面使用了代码

public class Example {

    public static void readCalendar(Context context) {

        ContentResolver contentResolver = context.getContentResolver();

        // Fetch a list of all calendars synced with the device, their display names and whether the
        // user has them selected for display.

        final Cursor cursor = contentResolver.query(Uri.parse("content://calendar/calendars"),
                (new String[] { "_id", "displayName", "selected" }), null, null, null);
        // For a full list of available columns see http://tinyurl.com/yfbg76w

        HashSet<String> calendarIds = new HashSet<String>();

        while (cursor.moveToNext()) {

            final String _id = cursor.getString(0);
            final String displayName = cursor.getString(1);
            final Boolean selected = !cursor.getString(2).equals("0");

            Log.v("anim","Id: " + _id + " Display Name: " + displayName + " Selected: " + selected);
            calendarIds.add(_id);
        }

        // For each calendar, display all the events from the previous week to the end of next week.        
        for (String id : calendarIds) {
            Uri.Builder builder = Uri.parse("content://calendar/instances/when").buildUpon();
            long now = new Date().getTime();
            ContentUris.appendId(builder, now - DateUtils.WEEK_IN_MILLIS);
            ContentUris.appendId(builder, now + DateUtils.WEEK_IN_MILLIS);

            Cursor eventCursor = contentResolver.query(builder.build(),
                    new String[] { "title", "begin", "end", "allDay"}, "Calendars._id=" + id,
                    null, "startDay ASC, startMinute ASC"); 
            // For a full list of available columns see http://tinyurl.com/yfbg76w

            while (eventCursor.moveToNext()) {
                final String title = eventCursor.getString(0);
                final Date begin = new Date(eventCursor.getLong(1));
                final Date end = new Date(eventCursor.getLong(2));
                final Boolean allDay = !eventCursor.getString(3).equals("0");

                Log.v("anim","Title: " + title + " Begin: " + begin + " End: " + end +
                        " All Day: " + allDay);
            }
        }
    }


}

公共类示例{
公共静态void readCalendar（上下文）{
ContentResolver ContentResolver=context.getContentResolver（）；
//获取与设备同步的所有日历的列表、它们的显示名称以及
//用户已将其选中以显示。
最终游标=contentResolver.query（Uri.parse（“content://calendar/calendars"),
（新字符串[]{“\u id”，“displayName”，“selected”}），null，null，null；
//有关可用列的完整列表，请参见http://tinyurl.com/yfbg76w

while（cursor.moveToNext（））{
最终字符串_id=cursor.getString（0）；
最终字符串displayName=cursor.getString（1）；
选择的最终布尔值=！cursor.getString（2）.equals（“0”）；
Log.v（“动画”、“Id:+\U Id+”显示名称：“+displayName+”选定：“+Selected”）；
calendarID.add（_id）；
}
//对于每个日历，显示从上周到下周结束的所有事件。
用于（字符串id:CalendarID）{
Uri.Builder=Uri.parse（“content://calendar/instances/when）。buildon（）；
long now=new Date（）.getTime（）；
appendId（builder，now-DateUtils.WEEK_IN_MILLIS）；
appendId（builder，now+DateUtils.WEEK，单位：毫秒）；
Cursor eventCursor=contentResolver.query（builder.build（），
新字符串[]{“标题”、“开始”、“结束”、“全天”}，日历。\u id=“+id，
空，“开始日期ASC，开始分钟ASC”）；
//有关可用列的完整列表，请参见http://tinyurl.com/yfbg76w
while（eventCursor.moveToNext（））{
最终字符串标题=eventCursor.getString（0）；
最终日期开始=新日期（eventCursor.getLong（1））；
最终日期结束=新日期（eventCursor.getLong（2））；
最终布尔值全天=！eventCursor.getString（3）.equals（“0”）；
Log.v（“动画”，“标题：”+Title+“开始：”+Begin+“结束：”+End+
“全天：”+全天）；
}
}
}
}

我得到了空点异常。

我的问题解决了，我使用了下面的

code

-

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());
    }

非常感谢！ 然而，你只能从一个日历中获取所有事件，就像你的谷歌主帐户一样，你如何从所有可用日历中获取事件

请注意，在内置的日历小部件上，您可以看到来自Gmail、Exchange、Facebook等网站的事件 如何获得这些事件以及

对于日期或周的特定事件，我使用 查询语句中的selection子句和selection Args在特定日期如下所示：

以下是选择和参数定义：

Uri content = Uri.parse("content://com.android.calendar/events");
String[] vec = new String[] { "calendar_id", "title", "description", "dtstart", "dtend", "allDay", "eventLocation" };
String selectionClause = "(dtstart >= ? AND dtend <= ?) OR (dtstart >= ? AND allDay = ?)";
String[] selectionsArgs = new String[]{"" + dtstart, "" + dtend, "" + dtstart, "1"};

下面是一种获取所有日历事件列表的方法

public static void readCalendarEvent(Context context) {

       ContentResolver contentResolver = context.getContentResolver();
       cursor = contentResolver.query(Uri.parse("content://com.android.calendar/events"), (new String[] { "_id", "title", "organizer", "dtstart", "dtend"}), null, null, null);

       List<GoogleCalendar> gCalendar = new ArrayList<GoogleCalendar>();
        try {

            if (cursor.getCount() > 0) {
                while (cursor.moveToNext()) {
                    GoogleCalendar googleCalendar = new GoogleCalendar();
                    // event_ID: ID of tabel Event 
                    int event_ID = cursor.getInt(0);
                    googleCalendar.setEvent_id(event_ID);
                    // title of Event
                    String title = cursor.getString(1);
                    googleCalendar.setTitle(title);
                    String mOrganizer = cursor.getString(2);
                    googleCalendar.setOrganizer(mOrganizer);
                    // Date start of Event
                    String dtStart = cursor.getString(3);
                    googleCalendar.setDtstart(dtStart);
                    // Date end of Event
                    String dtEnd = cursor.getString(4);
                    googleCalendar.setDtend(dtEnd);
                    gCalendar.add(googleCalendar);
                    Log.d("CaledarM",googleCalendar.getTitle()+" name = "+googleCalendar.getOrganizer()+" dateStart = "+googleCalendar.getDtstart()+" Size = " + gCalendar.size());
                }
