我正在android studio上做一个项目。问题是我无法将片段类添加到我的项目中。开始执行此项目时,我能够添加两个片段类。但是,在完成大约一半的项目之后,现在无法添加第三个片段类。当我添加第三个片段类并运行项目时,将弹出此异常:

我尝试了android.app.Fragmentandroid.support.v4.app.Fragment。两者都不起作用.....

最佳答案

试试这个,制作一个Java类并从Fragment扩展它。
这是片段类的基本结构。

public class MyFragment extends Fragment{

@Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.<your xml layout>, container, false);

        //Do your work here
        return view;
    }
}


并确保您从android.support.v4.app.Fragment对其进行了扩展
