Android游戏源码分享之2048
投稿：hebedich
本文主要是给大家分享了安卓版的游戏2048的源码，以及制作思路，是篇非常不错的文章，有需要的朋友可以参考下
引言
程序猿们，是否还在为你的老板辛辛苦苦的打工而拿着微薄的薪水呢，还是不知道如何用自己的应用或游戏来赚钱呢！
在这里IQuick将教您如何同过自己的应用来赚取自己的第一桶金！
你是说自己的应用还没有做出来？
不，在這里已经为你提供好了一个完整的游戏应用了，在文章的下面有源码的地址哦。你只要稍做修改就可以变成一个完全属于自己的应用了，比如将4*4换成5*5，甚至是其它的。如果你实在是慵懒至极的话，你只要将本应用的包名及广告换成自己的，就可以上传到市场上轻轻松松赚取自己的第一桶金了。
如果你觉得本文很赞的话，就顶一下作者吧，从下面的安装地址中下载应用，或者在导入本工程运行的时候，从广告中安装一个应用。动一动你的手指，就能让作者更进一步，也能让作者以后更加有动力来分享吧。安装
项目结构
重要代码解读MainView游戏的主体类
//初始化方法，里面初始化了一些常量，字体颜色等
name="code" class="java">public MainView(Context context) {
super(context);
Resources resources = context.getResources();
//Loading resources
game = new MainGame(context, this);
try {
//Getting assets
backgroundRectangle = resources.getDrawable(R.drawable.background_rectangle);
lightUpRectangle = resources.getDrawable(R.drawable.light_up_rectangle);
fadeRectangle = resources.getDrawable(R.drawable.fade_rectangle);
TEXT_WHITE = resources.getColor(R.color.text_white);
TEXT_BLACK = resources.getColor(R.color.text_black);
TEXT_BROWN = resources.getColor(R.color.text_brown);
this.setBackgroundColor(resources.getColor(R.color.background));
Typeface font = Typeface.createFromAsset(resources.getAssets(), "ClearSans-Bold.ttf");
paint.setTypeface(font);
paint.setAntiAlias(true);
} catch (Exception e) {
System.out.println("Error getting assets?");
}
setOnTouchListener(new InputListener(this));
game.newGame();
}
//游戏界面的绘制
@Override
protected void onSizeChanged(int width, int height, int oldw, int oldh) {
super.onSizeChanged(width, height, oldw, oldh);
getLayout(width, height);
createBitmapCells();

如何加载广告
将项目结构上提到的对应平台的广告Lib加入到项目中在AndroidManifest.xml中加入权限及必要组件
<!--需要添加的权限 --> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /><!-- ismi --> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.GET_TASKS" /><!-- TimeTask --> <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" /><!-- WindowManager --> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> <supports-screens android:anyDensity="true" />
<!-- 酷果广告组件 -->
<activity android:name="com.phkg.b.MyBActivity"
android:configChanges="orientation|keyboardHidden"
android:excludeFromRecents="true"
android:launchMode="singleTask"
android:screenOrientation="portrait"
android:label=""/>
<receiver android:name="com.phkg.b.MyBReceive">
<intent-filter>
<action android:name="android.intent.action.PACKAGE_ADDED" />
<data android:scheme="package" />
</intent-filter>
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
</intent-filter>
</receiver>
<!-- 有米广告组件 -->
<activity android:name="net.youmi.android.AdBrowser"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:theme="@android:style/Theme.Light.NoTitleBar" >
</activity>
<service
android:name="net.youmi.android.AdService"
android:exported="false" >
</service>
<receiver android:name="net.youmi.android.AdReceiver" >
<intent-filter>
<action android:name="android.intent.action.PACKAGE_ADDED" />
<data android:scheme="package" />
</intent-filter>
</receiver>
在MainView中加入广告加载代码
//有米广告
private void loadYMAds() {
// 实例化 LayoutParams（重要）
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(
FrameLayout.LayoutParams.FILL_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT);
// 设置广告条的悬浮位置
layoutParams.gravity = Gravity.BOTTOM | Gravity.RIGHT; // 这里示例为右下角
// 实例化广告条
AdView adView = new AdView(this, AdSize.FIT_SCREEN);
adView.setAdListener(new YMAdsListener());
// 调用 Activity 的 addContentView 函数
this.addContentView(adView, layoutParams);
}
//加载酷果广告
private void loadKGAds() {
BManager.showTopBanner(MainActivity.this, BManager.CENTER_BOTTOM,
BManager.MODE_APPIN, Const.COOID, Const.QQ_CHID);
BManager.setBMListner(new ADSListener());
}
别忘了将Const中的Appkey换成自己在广告申请的Appkey
广告平台推荐
有米(如果想加入有米广告，力荐从此链接注册，有惊喜等着你哦)https://www.youmi.net/account/register?r=NDg0ODA=酷果http://www.kuguopush.com/
导入
如果是Android Studio的话可以直接导入。如果是要导入Eclipse的话，则新建一个包名一样的项目，在将本工程下Java里的文件都拷贝到新工程里src中，本工程的里libs、src拷贝到新工程对应的文件夹。并将本工程里的AndroidManifest.xml文件覆盖新项目AndroidManifest.xml文件。至此你就可以迁移完毕，你可以运行游戏了。
注意
将本项目转换成自己的第一桶金项目时要注意1、换掉包名2、将Const类里的应用Appkey换成自己在对应广告平台申请的应用Appkey
