将图像添加到主视图/布局时出现运行时错误（我尝试了两者）。
代码从一个活动开始，我创建游戏板没问题，完成后游戏开始，一切顺利。当我按下按钮将图像添加到屏幕时会出现此问题，在将视图添加到主视图时出现运行时错误。在我的代码中，我只保留所有 Java，我避免使用 XML 文件，我想知道这是否可能是问题的一部分。我一直在阅读一些类似问题的解决方案，人们建议使用布局充气方法，但是如果没有 XML 文件，我找不到使用这种方法的参考。
这是我的代码
（PS 抱歉，我在预览窗口中看到它在某些时候中断了多么奇怪......错误日志在最后

非常感谢您的帮助，如果有人能看到我做错了什么或不理解。这是一个范围问题。我是否使用了正确类型的容器...我不知道 :(
