java如何在片段中的方法中膨胀布局

Question

实际上我有一个片段

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View promptView = inflater.inflate(R.layout.fragment_messages, container, false);

    sendRestoreRequest2();

    return promptView;
}


public void sendRestoreRequest2() {

     final TextView df=(TextView)promptView.findViewById(R.id.df);//this will give an error. I dont know how to inflate this one because this is a fragment.
    }

如何解决这个问题？因为在活动中，我们可以在方法中只使用final TextView df=（TextView）findviewbyd（R.id.df），它就会工作

Answer 1

试试这个：

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
   View promptView = inflater.inflate(R.layout.fragment_messages, container, false);
   sendRestoreRequest2(promptView);
   return promptView;
}

public void sendRestoreRequest2(View promptView) {
   final TextView df = (TextView) promptView.findViewById(R.id.df);
}
