我是android编程的新手。我一直在使用eclipse并尝试开发两个玩家的tic tac toe游戏，但是只要有玩家获胜，该应用就会不断崩溃。我尝试打开一个新活动-一个对话框，提示玩家x获胜，两个按钮提示再次播放或退出。 PlayerOne和PlayerTwo类仅将内容视图设置为对话框。我试着试着赶上startActivity方法，但随后却什么也没发生，我连续得到三个X或O，游戏一直在运行，没有任何对话框显示。有人可以帮我吗？这是我的代码：

最佳答案
两件事，当您初始化意图时，您使用的是Intent（String action）作为构造函数。 com.rohan.tictactoe.PlayerOne是动作吗？是你的班吗？如果是一堂课，那您真的不应该那样做。
尝试这个：
public void winner(){
Intent i = new Intent(this, PlayerOne.class);
Intent x = new Intent(this, PlayerTwo.class);
//blahblah rest of your code
}
其次，您需要将活动添加到您的AndroidManifest.xml中以使其正常运行。在您的AndroidManifest.xml中，必须在应用程序标记之间添加以下代码：
<activity android:name=".PlayerOne"/>
<activity android:name=".PlayerTwo"/>
