Question

我是Android开发的新手，我想制作一个tic tac toe游戏。

如何改进此代码以为计算机播放器制作随机选项？我想在这个tic tac toe游戏中添加一个单一的玩家功能。

我希望如果黄色玩家点击，那么红色玩家也会自动播放而不点击。

这里的代码是

据我了解你的问题，黄色玩家是玩游戏的玩家。红色播放器是汽车播放器。如果这是正确的，那么你可以通过回调方法实现这一目标。一旦黄色玩家轮到他（你必须要打任何方法来打转），在这个方法结束时给回叫红色玩家的召唤方法转为自动播放。（在回叫方法中你将调用的方法是红色球员的转身）。希望对你有所帮助。正如您所说，您是新的Android开发人员，对于回拨实施帮助您可以参考下面的帮助完整链接，
