Android游戏开发之SurfaceView动画

start()启动循环，并通过适当的方式结束循环进而结束整个线程。还要注意一点，所有对

Surface 的操作都必须要保证同步，因此我们会使用Synchronized 关键字，同步SurfaceHolder。

增加了GameThread 后的代码如下：

public class GameView extends SurfaceView implements Callback {

public static final String tag = "GameView";

//声明GameThread类实例

GameThread gameThread;

public GameView(Context context) {

super(context);

// TODO Auto-generated constructor stub

//获取SurfaceHolder

SurfaceHolder surfaceHolder = getHolder();

//添加回调对象

surfaceHolder.addCallback(this);

//创建GameThread类实例

gameThread = new GameThread(surfaceHolder);

}

public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2,

int arg3) {

// TODO Auto-generated method stub

Log.v(tag, "surfaceChanged");

}

public void surfaceCreated(SurfaceHolder arg0) {

// TODO Auto-generated method stub

Log.v(tag, "surfaceCreated");

//启动gameThread

gameThread.start();

}

public void surfaceDestroyed(SurfaceHolder arg0) {

// TODO Auto-generated method stub

Log.v(tag, "surfaceDestroyed");

//通过结束run()函数的方法结束gameThread，详见GameThread类的定义

gameThread.run = false;

}

/**

class GameThread extends Thread {

SurfaceHolder surfaceHolder;

//run()函数中控制循环的参数。

boolean run = true;

public GameThread(SurfaceHolder surfaceHolder) {

this.surfaceHolder = surfaceHolder;

}

@Override

public void run() {

// TODO Auto-generated method stub
