推荐答案
好吧，我发现这个整体的概念，即如何使用谷歌日历应用集成与Android手机的答案。
Ok i found the answer of this whole of the concept that how to use the google calendar application integration with the android phone.
code： -
首先，你设置这行，将去读取日历活动构成其他类构成的类，它是当前是ApplicationSettings.java。
first you set this line which will goes to read the calendar events form the other class form your class which is current is the ApplicationSettings.java .
calendar.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;
import android.database.Cursor;
import android.net.Uri;
import android.text.format.DateUtils;
public class ReadCalendar
{
static Cursor cursor;
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
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());

下面是整个的code是要贴这将只读取每一个事件形成你的日历与回发网址这是2.2及以上版本的帮助：
here is the whole of the code is to be posted which will simply reads each and every events form your calendar with the help of that postback url which is for 2.2 and above version:
Uri.parse("content://com.android.calendar/instances/when").buildUpon();
PL找到下这些版本低则2.2的Android和使用这些事件，你需要的地方......
pl find the under those version lower then 2.2 in android and use those events as you required place...
这篇关于从日历中获取事件的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
