java声明计算机每次都会获胜，尽管在Android应用程序中这不是正确的结果
我几乎在安卓上完成了一个tic-tac-toe应用程序（玩家对电脑），但我注意到我的游戏出现了一个小故障。不管结果如何，电脑总是赢。所以，若玩家连续三场或者是平局，它仍然表示计算机获胜，我不太确定我在代码中加入了什么错误导致了这一点。我怎样才能获得比赛的正确结果
以下是完整代码：

这是因为每当玩家一号通过调用
computerMove()打开时，你都会设置playerOneMove = false;（在if (playerOneMove) {），并且在该方法中，你会立即设置playeOneMove = false;如果不是这样的话，也请发布
switchPlayerTurn()方法此外，我认为你应该在
if(playerOneMove)之前提高你的获胜条件测试示例（我更改了您的条件，移动了测试获胜条件的代码，创建了其他方法……：
