android 卡通片学习系列（一）

老师今天开始讲android的游戏，讲到了view和surfaceview

下面是view的演示部分

private Paint paint;	//游戏里很少用double,都是用long	private int x=10,y=10;	private Thread th;	//线程控制	private boolean flag;			public boolean isFlag() {		return flag;	}	public void setFlag(boolean flag) {		this.flag = flag;	}	public MyView(Context context) {		super(context);		paint=new Paint();		paint.setColor(Color.BLUE);				setFocusable(true);		setFocusableInTouchMode(true);				flag=true;		th=new Thread(this);		th.start();			}	@Override	protected void onDraw(Canvas canvas) {		super.onDraw(canvas);		canvas.drawText("点我", x, y, paint);	}		@Override	public boolean onKeyDown(int keyCode, KeyEvent event) {		if (keyCode==KeyEvent.KEYCODE_DPAD_DOWN) {			System.out.println("down");			y++;		}		//重绘方法		invalidate();		return super.onKeyDown(keyCode, event);	}		@Override	public boolean onTouchEvent(MotionEvent event) {		//必须改为true，否则就会执行一次		x=(int) event.getX();		y=(int) event.getY();		invalidate();		return true;	}	@Override	public void run() {				while (flag) {			System.out.println("run");			x++;			y++;			try {				Thread.sleep(50);			} catch (InterruptedException e) {				e.printStackTrace();			}			postInvalidate();		}	}
