我正在尝试为Android制作TicTacToe游戏。但我有以下问题。 首先，我想 实现线程 到我的应用程序，但我没有成功（几乎尝试过任何事情）。 其次我想知道如何处理这两个错误（我不知道它们是否被称为错误）： 将堆（frag case）增长到65.24 MB，用于2567824字节分配 ， 跳过118帧！ applcation可能在其主线程上做了太多工作 （虽然我认为这可以通过线程实现来解决）
public class DrawClass extends View {
int index;
int x, y, RectX, RectY;

public Rect[] rectangles = new Rect[9];
// it will be our reference array as to what does each rectangle hold

Skipped 118 frames ! The applcation may be doing too much work on its main thread你正在做很多关于UI线程的工作。创建线程或使用asynctask来完成繁重的工作将解决此错误。看一下这个http://www.vogella.com/articles/AndroidBackgroundProcessing/article.html，就会有很好的解释。

为了帮助您解决线程和异步行为问题，您必须更加具体，但要找到性能问题的位置，您可以使用Android的profiling tools。
