安卓2048游戏开发
不多说的直接效果图超清效果图了解一下，看完觉得可以下面是代码可以试着写写。。想要源码可以私聊我
这是文件结构

5.最后贴一下AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.game">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity"
//就加了一行这个，效果是程序只能在竖屏运行。。
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
上面就是全部代码。注释不是特别好，还请多包涵，新手不习惯加注释。希望能给你们帮助。。
