<적용 방법>

1. Bottom Sheet Dialog 사용을 위한 라이브러리 추가

implementation 'com.google.android.material:material:1.1.0'

2. Bottom Sheet Dialog 레이아웃 생성

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

    <data>

        <variable
            name="dialog"
            type="com.android.example.BSDialog" />
    </data>

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <TextView
            android:id="@+id/titleTv"
            style="@style/BSDialogTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="안내"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

        <TextView
            android:id="@+id/contentTv"
            style="@style/BSDialogContent"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/title_tv" />


        <View
            android:id="@+id/view"
            android:layout_width="match_parent"
            android:layout_height="0.1dp"
            android:layout_marginTop="20dp"
            android:background="#8A8A8A"
            app:layout_constraintTop_toBottomOf="@+id/contentTv" />


        <androidx.constraintlayout.widget.ConstraintLayout
            android:id="@+id/button_layout"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/view">

            <ImageView
                android:layout_width="50dp"
                android:layout_height="50dp"
                android:padding="12dp"
                android:src="@drawable/ic_submit"
                app:layout_constraintBottom_toBottomOf="@+id/accept_btn"
                app:layout_constraintEnd_toEndOf="@+id/accept_btn"
                app:layout_constraintStart_toStartOf="@+id/accept_btn"
                app:layout_constraintTop_toTopOf="@+id/accept_btn" />

            <Button
                android:id="@+id/acceptBtn"
                android:layout_width="0dp"
                android:layout_height="match_parent"
                android:background="?attr/selectableItemBackground"
                android:textColor="@color/BlueText"
                android:textSize="14sp"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toStartOf="parent" />

        </androidx.constraintlayout.widget.ConstraintLayout>
    </androidx.constraintlayout.widget.ConstraintLayout>
</layout>

3. BottomSheetDialogFragment 클래스 생성

package com.android.example;

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

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.databinding.DataBindingUtil;

import com.comms.user.shift.R;
import com.comms.user.shift.databinding.BsdialogBtn1Binding;
import com.google.android.material.bottomsheet.BottomSheetDialogFragment;

public class BSDialog extends BottomSheetDialogFragment {

    private BsdialogBinding binding;
    private Context context;
    private String content;
    private View.OnClickListener cl;

    public BSDialog(Context context,
                        String content,
                        View.OnClickListener cl
    ) {
        this.context = context;
        this.content = content;
        this.cl = cl;
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        binding = DataBindingUtil.inflate(inflater, R.layout.bsdialog, container, false);

        // 다이얼로그 내용
        binding.contentTv.setText(content);
        // 확인 버튼
        binding.acceptBtn.setOnClickListener(cl);

        return binding.getRoot();
    }
}
