这两天重写了sample下面的LunarLander代码，忽然不明白为啥在 LunarView 下面要自己new一个线程来处理呢?既然都是通过while(true){}来画图，那直接在SurfaceView里面搞个循环有啥不可?

对比自己写的一个俄罗斯方块，就是直接继承了SurfaceView，通过Handler做动画处理，没觉得需要new一个线程来处理。

有人能指点迷津或者一起讨论讨论...

Java代码

/**

* View that draws, takes keystrokes, etc. for a simple LunarLander game.

*

* Has a mode which RUNNING, PAUSED, etc. Has a x, y, dx, dy, ... capturing the

* current ship physics. All x/y etc. are measured with (0,0) at the lower left.

* updatePhysics() advances the physics based on realtime. draw() renders the

* ship, and does an invalidate() to prompt another draw() as soon as possible

* by the system.
