Android ---snake源代码分析代码结构分析：Snake ：主游戏窗口SnakeView ：游戏视图类，是实现游戏的主体类TileView ：一个处理图片或其它Coordinate ：这是一个包括两个参数，用于记录X轴和Y轴简单类，其中包括一个比较函数.RefshHandler ：用于更新视图Snake这个类是游戏的主游戏窗口，是框架容器，1.游戏的开始：oncreate此外的亮点是：setContentView(yout.snake_layout);设置窗口的布局文件，这里Android123给大家说明的是，这里的snake_layout使用了自定义资源标签的方式，大家注意学习:这里我们可以看到来自SnakeView这个派生类的名称，由于Android内部的R.资源不包含SnakeView类，所以我们必须写清楚Package，比如com.exmple.android.snake.SnakeView 然后和其他控件使用一样，都是一个id然后宽度、高度、以及自定义的标签tileSize（尾巴长度），如下:<com.example.android.snake.SnakeViewandroid:id="@+id/snake"android:layout_width="fill_parent"android:layout_height="fill_parent"tileSize="12"/>2.onPause:关于这点，大家可以参考下在我blog中关于active生命周期/admin/blogs/379826在玩游戏过程中，如果有来电或是其它事件中断，这时应该把当前状态保存。

以便返回时，还可以继续玩游戏。

这就使用onSaveInstanceState实现保存当前状态。

TileView注：此部分解析来自: Android示例程序Snake贪食蛇代码分析(三)TileView，从名称上不难看出这是一个方砖类，就是生成一个方块。

1游戏简介贪吃蛇游戏是一款手机游戏，同时也是一款比较需要耐心的游戏。

贪吃蛇游戏是一条蛇，不停地在手机屏幕上游走，吃在手机屏幕上出现的食物。

当蛇吃掉1个食物后会变长，并且吃完食物时食物会消失，并立即随机生成1个新的食物，只要蛇头碰到屏幕四周或者碰到自己的身子，蛇就立即毙命.1.2开发目的及意义通过本次课程设计，了解android软件的开发过程，熟悉并掌握JA V A语言，程序关键在于表示蛇的图形及蛇的移动。

用一个小矩形块表示蛇的一节身体，身体每长一节，增加一个矩形块，蛇头用一节表示。

移动时必须从蛇头开始，所以蛇不能向相反的方向移动，如果不按任意键，蛇自行在当前方向上前移，但按下有效方向键后，蛇头朝着该方向移动，一步移动一节身体，所以按下有效方向键后，先确定蛇头的位置，而后蛇的身体随蛇头移动。

意义是方便人们在休闲时通过玩手机游戏获得一点快乐,同时锻炼自己的大脑.1.3开发环境及工具在Window8下进行，采用eclipse开发工具,基于安卓2.2操作系统。

// proj_test.cpp : Defines the entry point for the console application./*设计思路：1、首先开辟单链表，内有3个节点表示蛇身2、蛇每移动一次，开辟新节点，加入链表头结点作为蛇头，释放尾部节点，形成移动效果3、随机产生食物，若在移动中吃到食物，则本次周期无需释放尾部节点，蛇身加长按键指示:上:W下:S左:A右:D加速: 1减速：2*///头文件定义#include "stdafx.h"#include<stdio.h>#include <graphics.h>#include <malloc.h>#include <conio.h>#include <stdlib.h>#include <time.h>#include <math.h>#include <windows.h>#define Hori_Len 30 //水平格数struct node *FindSecTailNode(struct node *Pnode);
