因为日历是系统自带的，所以读写它一定要申请权限,也就是在AndroidManifest.xml加如下两行代码(一个读一个写):
<uses-permission android:name="android.permission.READ_CALENDAR"/>
<uses-permission android:name="android.permission.WRITE_CALENDAR"/>
Android中日历用了三个URL,分别是日历用户的URL,事件的URL，事件提醒URL,三个URL在Android2.1之前是如下的样子：
calanderURL = "content://calendar/calendars";
calanderEventURL = "content://calendar/events";
calanderRemiderURL= "content://calendar/reminders";
但是在Android2.2版本以后,三个URL有了改变，变成如下的样子:
calanderURL = "content://com.android.calendar/calendars";
calanderEventURL = "content://com.android.calendar/events";
calanderRemiderURL = "content://com.android.calendar/reminders";
简单的Demo,按照我的步骤一步一步的来:
第一步:新建一个Android工程命名为CalendarDemo.
第二步:修改main.xml布局文件,增加了三个按钮,代码如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<Button
android:id="@+id/readUserButton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Get a User"
/>
<Button
android:id="@+id/readEventButton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Get a Event"
/>
<Button
android:id="@+id/writeEventButton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Input a Event"
/>
</LinearLayout>
第三步:修改主核心程序CalendarDemo.java，代码如下:
package com.tutor.calendardemo;
import java.util.Calendar;
import android.app.Activity;
import android.content.ContentValues;
import android.database.Cursor;
import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class CalendarDemo extends Activity implements OnClickListener {
private Button mReadUserButton;
private Button mReadEventButton;
private Button mWriteEventButton;
private static String calanderURL = "";
private static String calanderEventURL = "";
private static String calanderRemiderURL = "";
//为了兼容不同版本的日历,2.2以后url发生改变
static{
if(Integer.parseInt(Build.VERSION.SDK) >= 8){
calanderURL = "content://com.android.calendar/calendars";
calanderEventURL = "content://com.android.calendar/events";
calanderRemiderURL = "content://com.android.calendar/reminders";
}else{
calanderURL = "content://calendar/calendars";
calanderEventURL = "content://calendar/events";
calanderRemiderURL = "content://calendar/reminders";
}
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setupViews();
}
private void setupViews(){
mReadUserButton = (Button)findViewById(R.id.readUserButton);
mReadEventButton = (Button)findViewById(R.id.readEventButton);
mWriteEventButton = (Button)findViewById(R.id.writeEventButton);
mReadUserButton.setOnClickListener(this);
mReadEventButton.setOnClickListener(this);
mWriteEventButton.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if(v == mReadUserButton){
Cursor userCursor = getContentResolver().query(Uri.parse(calanderURL), null,
null, null, null);
if(userCursor.getCount() > 0){
userCursor.moveToFirst();
String userName = userCursor.getString(userCursor.getColumnIndex("name"));
Toast.makeText(CalendarDemo.this, userName, Toast.LENGTH_LONG).show();
}
}else if(v == mReadEventButton){
Cursor eventCursor = getContentResolver().query(Uri.parse(calanderEventURL), null,
null, null, null);
if(eventCursor.getCount() > 0){
eventCursor.moveToLast();
String eventTitle = eventCursor.getString(eventCursor.getColumnIndex("title"));
Toast.makeText(CalendarDemo.this, eventTitle, Toast.LENGTH_LONG).show();
}
}else if(v == mWriteEventButton){
//获取要出入的gmail账户的id
String calId = "";
Cursor userCursor = getContentResolver().query(Uri.parse(calanderURL), null,
null, null, null);
if(userCursor.getCount() > 0){
userCursor.moveToFirst();
calId = userCursor.getString(userCursor.getColumnIndex("_id"));
}
ContentValues event = new ContentValues();
event.put("title", "与苍井空小-姐动作交流");
event.put("description", "Frankie受空姐邀请,今天晚上10点以后将在Sheraton动作交流.lol~");
//插入hoohbood@gmail.com这个账户
event.put("calendar_id",calId);
Calendar mCalendar = Calendar.getInstance();
mCalendar.set(Calendar.HOUR_OF_DAY,10);
long start = mCalendar.getTime().getTime();
mCalendar.set(Calendar.HOUR_OF_DAY,11);
long end = mCalendar.getTime().getTime();
event.put("dtstart", start);
event.put("dtend", end);
event.put("hasAlarm",1);
Uri newEvent = getContentResolver().insert(Uri.parse(calanderEventURL), event);
long id = Long.parseLong( newEvent.getLastPathSegment() );
ContentValues values = new ContentValues();
values.put( "event_id", id );
//提前10分钟有提醒
values.put( "minutes", 10 );
getContentResolver().insert(Uri.parse(calanderRemiderURL), values);
Toast.makeText(CalendarDemo.this, "插入事件成功!!!", Toast.LENGTH_LONG).show();
}
}
}
第四步:在AndroidManifest.xml中申请权限,代码如下:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.tutor.calendardemo"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".CalendarDemo"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.READ_CALENDAR"/>
<uses-permission android:name="android.permission.WRITE_CALENDAR"/>
</manifest>
第五步:运行上述Android工程,查看效果：

如果你想要查看日历的月视图、年视图，可以试试云便签
1、云便签中的日历日程也是可以通过微信提醒的
2、云便签的电脑桌面版和网页版都可以查看日历月视图
3、云便签中可以添加待办事项定时提醒、重复提醒和农历提醒等
4、我们在云便签中设置的日程提醒会直接同步到月视图中
