与众不同 windows phone (1) - Hello Windows Phone

作者：webabcd

介绍
与众不同 windows phone 7.5 (sdk 7.1)

• 使用 Silverlight 开发 Windows Phone 应用程序
• 使用 XNA 开发 Windows Phone 应用程序
• 使用 Silverlight 和 XNA 组合开发 Windows Phone 应用程序（在 Silverlight 中融入 XNA）

示例
1、使用 Silverlight 开发 Windows Phone App 的 Demo
MainPage.xaml

<phone:PhoneApplicationPage

    x:Class="Silverlight.MainPage"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"

    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

    mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768"

    FontFamily="{StaticResource PhoneFontFamilyNormal}"

    FontSize="{StaticResource PhoneFontSizeNormal}"

    Foreground="{StaticResource PhoneForegroundBrush}"

    SupportedOrientations="Portrait" Orientation="Portrait"

    shell:SystemTray.IsVisible="True">

    <StackPanel>

        <!--按钮-->

        <Button Name="btn" Content="hello webabcd" />

    </StackPanel>

</phone:PhoneApplicationPage>

MainPage.xaml.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Net;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;

using Microsoft.Phone.Controls;

namespace Silverlight

{

    public partial class MainPage : PhoneApplicationPage

    {

        public MainPage()

        {

            InitializeComponent();

            this.Loaded += new RoutedEventHandler(MainPage_Loaded);

        }

        void MainPage_Loaded(object sender, RoutedEventArgs e)

        {

            // 弹出 MessageBox 信息

            btn.Click += delegate { MessageBox.Show("hello webabcd"); };

        }

    }

}

2、使用 XNA 开发 Windows Phone App 的 Demo
Game1.cs

using System;

using System.Collections.Generic;

using System.Linq;

using Microsoft.Xna.Framework;

using Microsoft.Xna.Framework.Audio;

using Microsoft.Xna.Framework.Content;

using Microsoft.Xna.Framework.GamerServices;

using Microsoft.Xna.Framework.Graphics;

using Microsoft.Xna.Framework.Input;

using Microsoft.Xna.Framework.Input.Touch;

using Microsoft.Xna.Framework.Media;

namespace XNA

{

    // 启动时先 Initialize，再 LoadContent，退出时 UnloadContent

    public class Game1 : Microsoft.Xna.Framework.Game

    {

        // 图形设备（显卡）管理器，XNA 在游戏窗口上做的所有事情都要通过此对象

        GraphicsDeviceManager graphics;

        // 精灵绘制器

        SpriteBatch spriteBatch;

        // 2D 纹理对象

        Texture2D sprite;

        public Game1()

        {

            graphics = new GraphicsDeviceManager(this);

            // 指定游戏窗口的宽和高，不设置的话会花屏

            graphics.PreferredBackBufferWidth = this.Window.ClientBounds.Width;

            graphics.PreferredBackBufferHeight = this.Window.ClientBounds.Height;

            Content.RootDirectory = "Content";

            // 两次绘制的间隔时间，本例为每 1/30 秒绘制一次，即帧率为 30 fps。此属性默认值为 60 fps

            TargetElapsedTime = TimeSpan.FromSeconds(1f / );

            // 当禁止在锁屏状态下运行应用程序空闲检测（默认是开启的）时，将此属性设置为 1 秒钟，可减少锁屏启动应用程序时的耗电量。此属性默认值为 0.02 秒

            InactiveSleepTime = TimeSpan.FromSeconds();

        }

        /// <summary>

        /// 游戏运行前的一些初始化工作

        /// </summary>

        protected override void Initialize()

        {

            base.Initialize();

        }

        /// <summary>

        /// 加载游戏所需用到的资源，如图像和音效等

        /// </summary>

        protected override void LoadContent()

        {

            spriteBatch = new SpriteBatch(GraphicsDevice);

            // 将图片 Image/Son 加载到 Texture2D 对象中

            sprite = Content.Load<Texture2D>("Image/Son");

        }

        /// <summary>

        /// 手工释放对象，游戏退出时会自动调用此方法

        /// 注：XNA 会自动进行垃圾回收

        /// </summary>

        protected override void UnloadContent()

        {

        }

        /// <summary>

        /// Draw 之前的逻辑计算

        /// </summary>

        /// <param name="gameTime">游戏的当前时间对象</param>

        protected override void Update(GameTime gameTime)

        {

            // 用户按返回键则退出应用程序

            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)

                this.Exit();

            base.Update(gameTime);

        }

        /// <summary>

        /// 在游戏窗口上进行绘制

        /// </summary>

        /// <param name="gameTime">游戏的当前时间对象</param>

        protected override void Draw(GameTime gameTime)

        {

            // 清除游戏窗口上的所有对象，然后以 CornflowerBlue 颜色作为背景

            GraphicsDevice.Clear(Color.CornflowerBlue);

            // SpriteBatch.Draw() - 用于绘制图像，其应在 SpriteBatch.Begin() 和 SpriteBatch.End() 之间调用

            spriteBatch.Begin();

            spriteBatch.Draw(sprite, new Vector2((this.Window.ClientBounds.Width - sprite.Width) / , (this.Window.ClientBounds.Height - sprite.Height) / ), Color.White);

            spriteBatch.End();

            base.Draw(gameTime);

        }

    }

}
