半个小时移植Flash游戏到Android平台,flashandroid


网上有很多现成的Flash游戏,一直想在手机上玩,虽说Android2.2支持Flash,但是大多数游戏需要键盘控制,最多的就是方向键,而手机大多数没有键盘(有键盘的好像也不行),所以实际上就没办法玩了。
现在Rexsee提供了一个很简单的解决方案,可以迅速将Flash游戏移植到Android手机上(2.2以上)。(目前Rexsee已经开源,在社区可以查看全部的开发手册、API说明与源码, www.rexsee.com)

下面是一个例子,把经典的美羊羊卡丁车移植到了手机上,而且有两个版本,一个用虚拟键盘,一个用方向传感器。
所有代码是用HTML和JS写的,包括全部HTML,总共只有100多行。步骤如下:
  1. 准备键盘图片,这里用到了6个键,左、右、空格(跳跃)、退出、消息和Rexsee市场键,Rexsee提供了几套现成的键可以下载。将键的图片放到asset/keyboard/default/文件夹中,这样用"keyboard/default"来指定theme参数即可,否则要用放图片的文件夹的完整路径(本地SD卡或网络地址均可)来制定theme参数。文件名就是键值,后缀名是.png
  2. 将美羊羊卡丁车的swf文件放在asset/文件夹中
  3. 将横幅图片(这里是banner.png)和启动按钮图片(这里是startNow.png)放在asset/文件夹中
  4. 当然还有图标要放在res中,还要将string.xml中的首页地址设为file:///android_asset/index.html。这是唯一的一个程序文件,100多行。
  5. 这是离线版的,所以要下载Rexsee的JAR包,自己用Eclipse编译,如果嫌麻烦,可以在线编译一个首页地址指向服务器某个网页地址,然后将下面的index.html的代码放在这个文件中(有些路径要改,比如图片什么的),如果也想离线玩,可以在首次载入后将swf文件和图片自己或者用rexseeClient下载到本地。当然也可以不下载,就在线玩。

1.先看一下res/values/string.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">美羊羊卡丁车</string>
<string name="app_home">file:///android_asset/index.html</string>
<string name="rexsee_home">http://www.rexsee.com/flash/index.php</string>
</resources>

2.再看一下AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="MeiYangYangKaDingChe.rexsee" android:versionCode="1" android:versionName="1.0">
<supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" android:anyDensity="true" />
<application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar">
<activity android:name="rexsee.activity.RexseeActivity" android:configChanges="orientation|keyboardHidden" android:launchMode="singleTop">
<intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter>

</activity>
</application>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
</manifest>

3.最后是asset/index.html的源代码
