?在那本書用的是GameCanvas，我就用surfaceView實現(xiàn)了和實例2相同的效果

效果圖:

下面給出MainView 的代碼

    package com.wjh.demon_3;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.view.KeyEvent;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.SurfaceHolder.Callback;

public class MainView extends SurfaceView implements Callback,Runnable{
	int keyCode = 0;
	String keyAction = "";
	Thread gameThread = null;
	boolean isGame = true;
	SurfaceHolder holder = null;
	public MainView(Context context) {
		super(context);
		// TODO Auto-generated constructor stub
		setFocusable(true);
		getHolder().addCallback(this);
		holder = this.getHolder();
		
	}
	@Override
	public void run() {
		// TODO Auto-generated method stub
		while(isGame)
		{
			input();
			logic();
			doDraw();
			try {
				Thread.sleep(100);
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}		
		}
		
	}
	//開始游戲主線程
	public void start()
	{
		if(gameThread == null)
		{
		gameThread = new Thread(this);
		gameThread.start();
		}
	}
	//停止游戲主線程
	public void stop()
	{
		isGame = false;
		if(gameThread != null)
		{
			try {
				gameThread.join();
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
	}
	//輸入判斷
	public void input()
	{
		
	}
	//邏輯判斷
	public void logic()
	{
		
	}
	public void doDraw()
	{
		Canvas c = null;
		try
		{
		c = holder.lockCanvas();
		synchronized (holder) {
			paint(c);
		}
		}finally{
			if(c != null)
			{
			holder.unlockCanvasAndPost(c);
			}
		}
	}
	//畫圖
	public void paint(Canvas canvas)
	{
		Paint backGround = new Paint();
		backGround.setColor(Color.BLACK);
		//清屏
		canvas.drawRect(0, 0, getWidth(), getHeight(), backGround);
		//設(shè)置畫筆顏色
		Paint cPaint = new Paint();
		cPaint.setColor(Color.BLUE);
		cPaint.setTextSize(20);
		//輸出按鍵的設(shè)備碼
		canvas.drawText("KeyCode:", 10, 20,cPaint);
		canvas.drawText(""+keyCode,120,20,cPaint);
		//輸出按鍵的設(shè)備名
		canvas.drawText("KeyAction:", 10, 80, cPaint);
		canvas.drawText(keyAction, 120, 80, cPaint);
	}
	@Override
	public void surfaceChanged(SurfaceHolder holder, int format, int width,
			int height) {
		// TODO Auto-generated method stub
		
	}
	@Override
	public void surfaceCreated(SurfaceHolder holder) {
		// TODO Auto-generated method stub
		start();
		
	}
	@Override
	public void surfaceDestroyed(SurfaceHolder holder) {
		// TODO Auto-generated method stub
		stop();
		
	}
	
	public boolean onKeyDown(int keyCode, KeyEvent event) {
		// TODO Auto-generated method stub
		this.keyCode = keyCode;
		switch(keyCode)
		{
		case KeyEvent.KEYCODE_DPAD_UP:
			this.keyAction = "UP";
			break;
		case KeyEvent.KEYCODE_DPAD_DOWN:
			this.keyAction = "DOWN";
			break;
		case KeyEvent.KEYCODE_DPAD_LEFT:
			this.keyAction = "LEFT";
			break;
		case KeyEvent.KEYCODE_DPAD_RIGHT:
			this.keyAction = "RIGHT";
			break;
		case KeyEvent.KEYCODE_DPAD_CENTER:
			this.keyAction = "CENTER";
			break;		
		default:
			this.keyAction="NONE";
			break;
		}
		return super.onKeyDown(keyCode, event);
	}

}
