But I am getting this error:
但我收到此错误：
Error:(566, 26) error: cannot find symbol method getSupportFragmentManager()
After searching I find out that I can make this go away by extending from FragmentActivity
搜索后我发现我可以通过从 FragmentActivity 扩展来消除它
But currently my MainActivity is extending from public class Main extends ListActivitydue to some earlier requirements.
