第一步：创建好surfaceView模版第二步:在网上载取了一个小鸟的图片，大小为60*38第三步:点击屏幕，控制小鸟向上飞，然后自动下落，按差屏幕不放手时，小鸟旋停不动gameView代码：//自定义的mySurfaceView类，继承sufaceView实现surfaceHolder.clllback和线程Runnablepublic class MyGameView extends SurfaceView implements SurfaceHolder.Callback,Runnable{ private SurfaceHolder sh;//SurfaceView控制器 private Canvas iCanvas;//画布 private Paint ipaint;//画笔 private Path ipath;//路径 private boolean isRunning=true;//布尔参数，死循环提交绘图方法，直到退出false private float screenWidth, screenHeight;// 屏幕宽/高 float x,y;//小鸟出现时的x,y坐标 Bitmap bitmap_Bird; BirdManager birdManager; Context mContext; //带上下文参的构造方法，在里面实例化组件 public MyGameView(Context context) { super(context); mContext = context; sh=this.getHolder();//获到surfaceHolder控制器 ipaint=new Paint();//获取画笔 ipath=new Path();//获到路径 ipaint.setColor(Color.RED);//设置画笔颜色 ipaint.setStyle(Style.STROKE);//设置画笔样式() ipaint.setStrokeWidth(5);//设置画笔的宽度 sh.addCallback(this);//监听控制器(添加回调函数) this.setFocusable(true);//设置当前焦点 bitmap_Bird = BitmapFactory.decodeResource(context.getResources(), R.drawable.bird60); } //死循环每隔100毫秒调用自定义具体画的方法，直到退出设为false @Override public void run() { while(isRunning){ drawView();//调用自定义具体画的方法 try { Thread.sleep(100); } catch (InterruptedException e) { e.printStackTrace(); } } } //自定义画法 private void drawView() { try { if(sh!=null){ iCanvas=sh.lockCanvas();//获取画布 //设置画笔和位图没有锯齿 iCanvas.setDrawFilter(new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG)); iCanvas.drawColor(Color.WHITE); birdManager.drawBird(iCanvas); //iCanvas.drawBitmap(bitmap_Bird, x, y, null); } } catch (Exception e) { }finally{ if(iCanvas!=null){ sh.unlockCanvasAndPost(iCanvas);//解锁画布并提交 } } } //触屏事件 @Override public boolean onTouchEvent(MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN://按下去 System.out.println("down"); //birdManager.moveUp(); //如果在这加setIsMove(false)，当按着屏幕不放手时，小鸟玄停不动 birdManager.setIsMove(false); break; case MotionEvent.ACTION_UP://放开 System.out.println("up"); //如果加下面注释掉的代码，小鸟会不停的向下掉// birdManager.setIsMove(false);// try {// Thread.sleep(50);// } catch (InterruptedException e) {// // TODO 自动生成的 catch 块// e.printStackTrace();// } birdManager.setIsMove(true); new Thread(){ public void run() { birdManager.moveUp(); }; }.start(); break; case MotionEvent.ACTION_MOVE://移动 break; default: break; } //invalidate();//立刻重绘 return true;//返回true，提交给当前视图 } @Override public void surfaceCreated(SurfaceHolder holder) { new Thread(this).start();//启动线程 } @Override public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { screenWidth = (float) getWidth(); screenHeight = (float) getHeight(); System.out.println("screenWidth="+screenWidth); System.out.println("screenHeight="+screenHeight); x = screenWidth/8; y = screenHeight*3/4; birdManager = new BirdManager(mContext,x,y,screenHeight); } @Override public void surfaceDestroyed(SurfaceHolder holder) { //退出界面，先设循环参数为false，等线程停了，再睡个300毫秒，再真正退出 isRunning=false; try { Thread.sleep(300); } catch (InterruptedException e) { e.printStackTrace(); } }}
