从日历获取事件

我的问题是，我不得不做一个演示应用程序，其中我想读取谷歌日历的事件，因为我已经手动插入事件的标题，事件的时间和整个事件的细节事件。 现在我需要只是那些日历forms的事件。 为此，我试图使用提供日历api类的gcode（google code）api。 但仍然无法读取这些事件

Answer 1

上面的代码是非常糟糕的（它似乎并没有在ICS中工作 – 绝对列名称是不同的）

这里的网页： http : //developer.android.com/guide/topics/providers/calendar-provider.html

提供了一个更好的概述。 检索日历的（很简单）代码：

public class CalendarContentResolver { public static final String[] FIELDS = { CalendarContract.Calendars.NAME, CalendarContract.Calendars.CALENDAR_DISPLAY_NAME, CalendarContract.Calendars.CALENDAR_COLOR, CalendarContract.Calendars.VISIBLE }; public static final Uri CALENDAR_URI = Uri.parse("content://com.android.calendar/calendars"); ContentResolver contentResolver; Set<String> calendars = new HashSet<String>(); public CalendarContentResolver(Context ctx) { contentResolver = ctx.getContentResolver(); } public Set<String> getCalendars() { // Fetch a list of all calendars sync'd with the device and their display names Cursor cursor = contentResolver.query(CALENDAR_URI, FIELDS, null, null, null); try { if (cursor.getCount() > 0) { while (cursor.moveToNext()) { String name = cursor.getString(0); String displayName = cursor.getString(1); // This is actually a better pattern: String color = cursor.getString(cursor.getColumnIndex(CalendarContract.Calendars.CALENDAR_COLOR)); Boolean selected = !cursor.getString(3).equals("0"); calendars.add(displayName); } } } catch (AssertionError ex) { /*TODO: log exception and bail*/ } return calendars; } } 

希望这可以帮助！

好吧，我find了这个整个概念的答案，如何使用谷歌日历应用程序与Android手机的集成。

码： –

首先你要设置这一行来读取日历事件forms的其他类forms你的类当前是ApplicationSettings.java。

ReadCalendar.readCalendar(ApplicationSettings.this);

 package com.mycalendarevents.android; import java.util.Date; import java.util.HashSet; import java.util.regex.Pattern; import android.content.ContentResolver; import android.content.ContentUris; import android.content.Context;

// Fetch a list of all calendars synced with the device, their display names and whether the cursor = contentResolver.query(Uri.parse("content://com.android.calendar/calendars"), (new String[] { "_id", "displayName", "selected"}), null, null, null); HashSet<String> calendarIds = new HashSet<String>(); try { System.out.println("Count="+cursor.getCount()); if(cursor.getCount() > 0) { System.out.println("the control is just inside of the cursor.count loop"); while (cursor.moveToNext()) { String _id = cursor.getString(0); String displayName = cursor.getString(1); Boolean selected = !cursor.getString(2).equals("0"); System.out.println("Id: " + _id + " Display Name: " + displayName + " Selected: " + selected); calendarIds.add(_id); } } } catch(AssertionError ex) { ex.printStackTrace(); } catch(Exception e) { e.printStackTrace(); } // 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://com.android.calendar/instances/when").buildUpon(); //Uri.Builder builder = Uri.parse("content://com.android.calendar/calendars").buildUpon(); long now = new Date().getTime(); ContentUris.appendId(builder, now - DateUtils.DAY_IN_MILLIS * 10000); ContentUris.appendId(builder, now + DateUtils.DAY_IN_MILLIS * 10000); Cursor eventCursor = contentResolver.query(builder.build(), new String[] { "title", "begin", "end", "allDay"}, "Calendars._id=" + 1, null, "startDay ASC, startMinute ASC"); System.out.println("eventCursor count="+eventCursor.getCount());

} } break; } } } 

这里是整个代码将被发布，它将简单地读取每个事件forms的日历与该回发url为2.2和以上版本的帮助：

 Uri.parse("content://com.android.calendar/instances/when").buildUpon(); 

PLfind在那些版本低于2.2在Android下，并使用这些事件，因为你需要的地方…

Answer 3

我知道这是一个旧的post，但是我发现如果有人在不久的将来需要解决scheme的话，我会find灵感来优化Akash Takkar给出的答案。

问题

---

具体来说，我在原始代码中发现了一些问题：

1. 检索日历事件的循环不成熟
   • 因此，只有第一个日历的事件才被检索到
2. 每个日历中的第一个事件通过使用eventCursor.moveToFirst（）; 之后直接转到while循环中的下一个事件
3. eventCursor中的日历ID未正确设置
   • “Calendars._id =”+ 1，应该是“Calendars._id =”+ id，
4. 别人很难指定自己的时间范围
5. 目前的解决scheme不是面向对象的，这将具有许多优点
6. 可读性和文档不是最好的

解决scheme

---

我在这里创build了一个Github库，它返回一个指定时间范围内的事件对象列表，可以在这里find：

https://github.com/david-laundav/CalendarService

源文件可以在“CalendarService / src / dk / CalendarService”下find。

用例

解决scheme本身包含两个不同的方法用于不同的目的

第一个用例：

 CalendarService.readCalendar(class.this) // where class.this is either your class or the context 

此方法将返回+/- 1天的事件列表

第二个用例：

您也可以指定自己的时间范围：

 CalendarService.readCalendar(class.this, int days, int hours) 

一个例子可能是：

 CalendarService.readCalendar(class.this, 2, 5) 

这样做会返回一个+/- 2天和+/- 5小时的事件列表。

该服务已经过testing，但请告诉我，如果您遇到任何问题。

Answer 4

这篇文章有点旧了，但这里是另一个简单的解决scheme，用于获取Android中与Calendar内容提供者相关的数据：

使用这个lib： https ： //github.com/EverythingMe/easy-content-providers

现在，获取所有日历：

 CalendarProvider calendarProvider = new CalendarProvider(context); List<Calendar> calendars = calendarProvider.getCalendars().getList(); 

每个日历都有所有的字段，所以你可以得到你需要的任何信息： id，name，calendarColor，ownerAccount，accountName，calendarAccessLevel，…

或者，获取特定日历的所有事件 ：

 List<Event> calendars = calendarProvider.getEvents(calendar.id).getList(); 

也有select提醒，参加者，实例 。

它适用于列表或光标，并有一个示例应用程序，看看它的外观和工作。 事实上，所有的Android内容提供商都支持： Contacts（联系人），SMS（短信），Calls（电话）…具有所有选项的全文档： https ： //github.com/EverythingMe/easy-content-providers/wiki/Android-providers

希望它帮助:)

Answer 5

使用此代码获取一天的日历事件。

 public static void readCalendarEvent(Context context) throws ParseException { ContentResolver contentResolver = context.getContentResolver(); Calendar calendar = Calendar.getInstance(); String dtstart = "dtstart"; String dtend = "dtend"; SimpleDateFormat displayFormatter = new SimpleDateFormat("MMMM dd, yyyy (EEEE)"); stime=displayFormatter.format(calendar.getTime()); SimpleDateFormat startFormatter = new SimpleDateFormat("MM/dd/yy"); String dateString = startFormatter.format(calendar.getTime()); long after = calendar.getTimeInMillis(); SimpleDateFormat formatterr = new SimpleDateFormat("hh:mm:ss MM/dd/yy"); Calendar endOfDay = Calendar.getInstance(); Date dateCCC = formatterr.parse("23:59:59 " + dateString); endOfDay.setTime(dateCCC); cursor = contentResolver.query(Uri.parse("content://com.android.calendar/events"), (new String[] { "calendar_id", "title", "description", "dtstart", "dtend","eventTimezone", "eventLocation" }), "(" + dtstart + ">" + after + " and " + dtend + "<" + endOfDay.getTimeInMillis() + ")", null, "dtstart ASC"); /*String[] COLS={"calendar_id", "title", "description", "dtstart", "dtend","eventTimezone", "eventLocation"}; cursor = contentResolver.query( CalendarContract.Events.CONTENT_URI, COLS,null, null, null);*/ gCalendar = new ArrayList<GoogleCalendar>(); try { if (cursor.getCount() > 0) { while (cursor.moveToNext()) { GoogleCalendar googleCalendar = new GoogleCalendar(); gCalendar.add(googleCalendar); int calendar_id = cursor.getInt(0); googleCalendar.setCalendar_id(calendar_id); String title = cursor.getString(1); googleCalendar.setTitle(title); String description = cursor.getString(2); googleCalendar.setDescription(description); String dtstart1 = cursor.getString(3); dt=convertDate(dtstart1,"hh:mm:ss"); googleCalendar.setDtstart(dt); String dtend1 = cursor.getString(4); googleCalendar.setDtend(dtend1); String eventTimeZone=cursor.getString(5); googleCalendar.setEventTimeZone(eventTimeZone); String eventlocation = cursor.getString(6); googleCalendar.setEventlocation(eventlocation); } } } catch (AssertionError ex) { ex.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } } }
