自己还是小码畜 仍然有很多很多不懂得地方 所以这个博客只能说是作为一个个人笔记本的形式存在吧 刚好最近在实训Android 就记录一点自己认为有用的小知识吧 如果有幸能够帮助到别人 那是再好不过了 废话不多说吧 小码畜今天要记录的是一个简易版的猜数字游戏
搭建的环境具体如下所示 一个实体类 一个工具类 创建了Activity 以及分别对应的xml文件 实现后的运行界面如下
初始（开始）界面
游戏进入界面 时限为30秒 时间到了自动返回退出
好了 上代码吧
工具类：
package Utils; /** * Created by 4820 on 2017/6/6. */ public class AppConstants { private AppConstants(){} //标识返回方 public static final int RESULT_CODE_GAME_WIN = 11; public static final int RESULT_CODE_GAME_FAIL = 12; public static final String EXTRA_KEY_LEVEL="level"; }
实体类：
package Bussiness; import java.util.Random; /** * Created by 4820 on 2017/6/6. */ public class Game { public static final int LEVEL_NOEMAL = 50; public static final int LEVEL_HARD = 100; private int RandomNumber; private Random random; private String Tittle; private static final int REQUEST_CODE_MENU = 10; public String getTittle() { return Tittle; } public Game(int pLevel) { random = new Random(); RandomNumber = random.nextInt(pLevel); Tittle = "请输入0—" + pLevel + "的数字"; } public String guessNumber(int pInputNumber) { if (pInputNumber > RandomNumber) { return "Your number should be smaller!"; } if (pInputNumber < RandomNumber) { return "Your number should be bigger!"; } else { return "You got it!Congratulation!"; } } }

偷个懒吧 都是直接从项目里复制粘贴过来的 希望能帮助到大家吧
也希望自己能坚持写博 成为一个小习惯吧
