Android 在片段的dialogfragment中未调用OnCreateView

我有一个片段，单击按钮后执行或显示对话框片段。这个对话框片段显示了一个由代码生成的表，但是当我尝试单击该对话框上的按钮时，它会显示出来

当我在LogCat中跟踪它时，不会调用对话框片段onCreateView。有人能帮我解释一下吗？。我还不太擅长android编程，我知道我还有很多东西要学

下面是调用对话框片段的片段代码

而且一定要读


您可以实现onCreateDialog（Bundle）来创建自己的自定义对话框对象，而不是（或除了）实现onCreateView（LayoutInflater、ViewGroup、Bundle）来生成对话框内部的视图层次结构

因此，您应该使用：

@Override
public Dialog onCreateDialog(Bundle savedInstanceState)

取代：

public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState)

而不是

public static DialogFragment newInstance(...) {
    DialogFragment f = new DialogFragment();
    return f;
}

写

也可以使用Bundle和setArguments，getArguments来传递参数。
将此
对话框片段f=new DialogFragment（）；
更改为
ShowLstDialog f=new ShowLstDialog（）
@Raghunandan，为什么不将其作为答案发布？视图在哪里？如果要使用
