作为新手，写的博客一开始也没什么人看吧，看了一下浏览量最多还有留言的一篇是我思路写的最清晰和独特的一篇，看来用点心来写，对自己对大家都好，不能草草了事 。勤于学习，勤于总结归纳，勤于提高效率。在小项目中入手学习各种知识点可能效率更高，更能把知识点串联起来。
今天写的博客是2048，说实话我是开始要写2048的时候才下一个来玩一下，之前是不懂的，玩了之后发现简单易入迷。下面直入主题，
一开始，首先要熟悉2048这个游戏，最好写一下规则说明书，这里我就不列出来了。
效果图展示：开始界面——>功能选择界面——>游戏界面
功能介绍：
开始界面：五秒之后进入功能选择界面
功能选择界面：根据不同的按钮来选择游戏的模式，可以选择不同模式，对应会有不同的图片进入游戏界面就开始播放背景音乐
游戏界面：1.记录分数；2.保留最高分；3.游戏区域符合游戏规则；4.背景音乐的播放开始暂停和停止；5.移动合并的声音 ； 6.游戏重来； 7.赢或者输跳出对话框
核心思想：(可以看完代码再来体会，或者体会完能有所启发后自己写)
做完这个2048后，给我最大的感觉就是把游戏界面当做一个自定义组件来实现，就像是系统自给的组件，比如按钮，按钮有自己的颜色大小外观，你点击按钮会有点击事件（切换图片显示下按效果），那么一个游戏界面也是这样的，有自己的颜色大小外观，和响应事件，那么这些内容就要我们自己来实现。
其次就是2048的游戏逻辑，移动、合并、判断输赢，这些都要好好思考算法。经典地用到了二维数组来存储卡片位置，便于增删的链表来记录空位置。
再然后，如何打造个性化的2048，就是把数字变成自己喜欢的图片咯~数字逻辑转换为图像逻辑时，运用到了数组，算是比较笨的方法，但也是最容易想到的。
Last but not least,(莫名其妙想用到这个短语。。)，传参问题，一是方式，activity之间的跳转用intent来传参；一般的用getxx,setxx来传参；自定义组件上下文context不用传构造函数里有。二是先后顺序，一开始我把获取参数放在GameView的构造函数里，这样GameView在初始化时已经执行了获取参数，参数来不及传过来的。
实现流程：
java代码：
