android怎样实现日历年视图?

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 = "困亏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工程命名为拆衫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:修改主旅尺腔核心程序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：

==========================

Include MonthPager in your layout XML.

目前来看 相比于Dialog选择日历 我的控件更适合于Activity/Fragment在Activity的 onCreate或者Fragment的 onCreateView 你需要实现这两个方法来启动日历并装填进数据

使用此方法回调日历点冲扰击事件

使逗判橘用此方法初始化日历标记数据

使用此方法给MonthPager添加上相关山团监听

Gradle:

Step 1. Add it in your root build.gradle at the end of repositories:

Step 2. Add the dependency
