从片段打开 DialogFragment - FragmentManager 出错

Question

嘿，我目前尝试将 DialogFragment 添加到 Fragment。当我点击 TextView 时它应该会打开：

片段：

public class FragmentOneRm extends Fragment {



 @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    myContext = (main_container)this.getActivity();

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) { mTextViewMaxWeight.setOnLongClickListener(new View.OnLongClickListener() {
 //other code         
        @Override
        public boolean onLongClick(View v) {
            DialogWeightConverter dialog = DialogWeightConverter.newInstance();
       // Problem with getFragmentManager() 
            dialog.show(getFragmentManager(), "fragmentDialog");

        }
    });


    return view; 

出现以下错误：Cannot resolve methode show(android.app.FragmentManager, java.lang.string)

是的，我知道这个问题已经存在，但解决方案对我不起作用：/

我的 DialogFragment：

公共类 DialogWeightConverter 扩展 DialogFragment {

Context mContext;

public DialogWeightConverter() {
    mContext = getActivity();
}


@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    Dialog dialog = builder.create();

    return dialog;
}

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

如果您需要更多来自项目的代码，我会添加它

感谢您的帮助和问候

您的DialogWeightConverter 扩展自android.support.v4.app.DialogFragment？试试getActivity().getSupportFragmentManager()
