我是编程的新手，我正在制作一个只有基本功能的非常简单的二十一点游戏。当我在模拟器上运行程序时，它可能只运行一只手，两只，有时是5只或更多，但是当我点击三个按钮之一时，它总是在某个阶段停止响应。有一个启动画面，运行三秒钟，并有一个线程从该活动开始，启动此菜单活动。任何人都可以告诉为什么会这样吗？它通常发生在我按下其中一个按钮时，即使没有太多的计算机

在eclipse中使用调试器找出它被冻结的位置。
即使使用快速PC，Android模拟器也非常慢。
答案 1 :(得分：0)
尝试使用低分辨率模拟器。
从android-sdk \ tools打开DDMS，检查哪个方法或线程需要更多时间来执行。
当有功能（计算）事情在运行时使用AsyncTask或Handler。
