如何运用surfaceviewAndroid进行2d游戏贪吃蛇的开发，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
我们先看一下这个同步框架，看看骚年你能不能自己领悟。
GameView.java(继承自SurfaceView)
package com.next.eatsnake;import android.content.Context;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.view.MotionEvent;import android.view.SurfaceHolder;import android.view.SurfaceView;import android.view.View;import android.view.View.OnTouchListener;import java.util.Random;/** * Created by Next on 2016/3/24 0024. */public class GameView extends SurfaceView implements SurfaceHolder.Callback,OnTouchListener,Runnable { enum GameState{ Menu, Playing, Over; } GameState gameState;//游戏状态 Thread thread;//游戏线程 Boolean flag;//游戏循环控制标志 Canvas canvas;//画布 Paint paint;//画笔 SurfaceHolder holder;//SurfaceView控制句柄 Random random;//随机数 NextEvent nextEvent;//游戏输入事件 int scrW,scrH;//屏幕的宽和高 public GameView(Context context) { super(context); gameState = GameState.Menu; flag = true; paint = new Paint(); paint.setAntiAlias(true);//笔迹平滑 thread = new Thread(this); random = new Random(); nextEvent = new NextEvent(); holder = this.getHolder(); holder.addCallback(this); this.setOnTouchListener(this); setKeepScreenOn(true); scrW = ((MainActivity)context).getWindowManager().getDefaultDisplay().getWidth(); scrH = ((MainActivity)context).getWindowManager().getDefaultDisplay().getHeight(); } @Override public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN) { nextEvent.setDownX((int) event.getX()); nextEvent.setDownY((int) event.getY()); }else if (event.getAction() == MotionEvent.ACTION_UP) { nextEvent.setUpX((int) event.getX()); nextEvent.setUpY((int) event.getY()); } return true; } private void mLogic(){ switch (gameState){ case Menu: menuLogic(); break; case Playing: playingLogic(); break; case Over: overLogic(); break; } nextEvent.init();//每次逻辑循环后，清空事件 } private void menuLogic(){ if(nextEvent.getUpX() > 0){ gameState = GameState.Playing; } } private void playingLogic(){ if(nextEvent.getDir() == NextEvent.DOWN){ gameState = GameState.Over; } } private void overLogic(){ if(nextEvent.getDir() == NextEvent.RIGHT){ gameState = GameState.Menu; } } private void mDraw(){ try { canvas = holder.lockCanvas(); canvas.drawColor(Color.WHITE); switch (gameState){ case Menu: menuDraw(canvas); break; case Playing: playingDraw(canvas); break; case Over: overDraw(canvas); break; } }catch (Exception e){ e.printStackTrace(); }finally { holder.unlockCanvasAndPost(canvas); } } private void menuDraw(Canvas canvas){ paint.setColor(Color.RED); paint.setTextSize(50); canvas.drawText("I am in menu.Touch me to next scence",100,100,paint); } private void playingDraw(Canvas canvas){ paint.setColor(Color.RED); paint.setTextSize(50); canvas.drawText("I am in playing,Slide down to next scence ",100,100,paint); } private void overDraw(Canvas canvas){ paint.setColor(Color.RED); paint.setTextSize(50); canvas.drawText("I am in over,Slide right to next scence",100,100,paint); } //这里就是同步触发机制了 //每一个时钟周期，执行一次逻辑方法和绘图方法 @Override public void run() { while(flag){ mLogic(); mDraw(); try { Thread.sleep(500); }catch (Exception e){ e.printStackTrace(); } } } //SurfaceView创建时调用 @Override public void surfaceCreated(SurfaceHolder holder) { thread.start(); } //SurfaceView发生改变时调用 @Override public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { } //SurfaceView销毁时调用 @Override public void surfaceDestroyed(SurfaceHolder holder) { flag = false; }}这只是一个游戏框架，还没有往里写任何内容，但根据我的经验（虽然我也没有很多经验），这里已经包括了所有游戏（这里特指小游戏-_-）的主体框架代码，有了这个框架，我们就只需要写游戏的逻辑和绘图方法了，不用纠结怎么搭建游戏框架了。
这里我还加了一个NextEvent的方法，在里面我封装了上个游戏用到的滑动手势，在这个挨踢圈里，人们最常说的一句话就是：不要重复造轮子。当我们看到写了很多重复代码时，就是我们需要精简的时候了。
上代码：
NextEvent.java
package com.next.eatsnake;/** * Created by Next on 2016/3/24 0024. */public class NextEvent { public static final int LEFT = 1; public static final int RIGHT = 2; public static final int UP = 3; public static final int DOWN = 4; public static final int QUIET = -1;//没有滑动 private int dir; private int downX,downY,upX,upY; public NextEvent() { init(); } public void init(){ this.dir = QUIET; this.downX = -1; this.downY = -1; this.upX = -1; this.upY = -1; } public int getDir(){ float offsetX,offsetY; offsetX = upX - downX; offsetY = upY - downY; if (Math.abs(offsetX) > Math.abs(offsetY)) { if (offsetX > 5 ) { dir = RIGHT; }else if (offsetX < -5) { dir = LEFT; } }else { if (offsetY > 5) { dir = DOWN; }else if (offsetY < -5) { dir = UP; } } return dir; } public int getDownX() { return downX; } public void setDownX(int downX) { this.downX = downX; } public int getDownY() { return downY; } public void setDownY(int downY) { this.downY = downY; } public int getUpX() { return upX; } public void setUpX(int upX) { this.upX = upX; } public int getUpY() { return upY; } public void setUpY(int upY) { this.upY = upY; }}这个NextEvent是用来存储用户输入事件的，我们只是存储，而没有直接触发游戏逻辑。那么什么时候用到读取这个NextEvent呢？如果你仔细看了第一段代码，应该已经知道了--在每一个时钟周期的逻辑方法里判断NextEvent，并由此改变游戏逻辑。这种就是同步机制，而用户输入事件游戏逻辑就随之改变的就是异步机制。
下面我们用这个框架做一个贪吃蛇游戏，效果图如下：
