프래그먼트에 CustomDialog 띄우기 질문입니다!

Question

package com.duckcom.duckcal.Fragment;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import androidx.fragment.app.DialogFragment;
import androidx.fragment.app.Fragment;

import com.duckcom.duckcal.R;

public class FragmentDialog extends DialogFragment {


    private Fragment fragment;

    public FragmentDialog() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.dialog, container, false);

        Bundle args = getArguments();
        String value = args.getString("key");

     
        fragment = getActivity().getSupportFragmentManager().findFragmentByTag("tag");

        if (fragment != null) {
            DialogFragment dialogFragment = (DialogFragment) fragment;
            dialogFragment.dismiss();
        }
        return view;
    }
}

FragmentDialog.java 입니다.

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="400dp"
        android:orientation="vertical"
        android:gravity="center">
        <TextView
            android:text="DialogFragment"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </LinearLayout>
</layout>

<dialog.xml 입니다>

 

프래그먼트에서 커스텀 다이얼로그 띄우기를 하고 싶습니다.

인터넷에 있는 코드를 써서 실행했는데 아래와 같은 에러 로그가 뜹니다.

(라이브러리 에러는 빼고 적었습니다.)

at com.duckcom.duckcal.Fragment.FragmentDialog.onCreateView(FragmentDialog.java:23)

해당 코드도 붙입니다.

View view = inflater.inflate(R.layout.dialog, container, false);

대체 왜 에러가 나는 걸까요?

감사합니다.

Dialog xml이 잘 못 된것 같네요. 위와 같이 고쳐 보세요.
