我需要这个应用程序的一些帮助。我不知道删除或更改了什么，以便在没有类别的情况下显示引号中的文字。我的意思是当我按下按钮时，show apper随机而不选择类别。我想删除那些类别。 我花了2个小时，但我是初学者，我没有找到好办法。

我真的不明白你的问题，但是，从我的理解来看。要使代码至少编译，您需要：
1）评论此行：
Start loading the ad in the background.
所以看起来应该是这样的：
//Start loading the ad in the background.
2）评论或删除代码中的所有loadCategory();
希望有所帮助

我评论了一行loadCateogy（）;但没有运气。如果未选中类别，则在按下按钮时不会显示文本。
