一、实现效果图

二、代码

1、bottom_popwindoow.xml中的代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <Button
        android:id="@+id/btn_01"
        android:onClick="btn_01"
        android:layout_height="55dp"
        android:layout_width="match_parent"
        android:textAlignment="textStart"
        style="?android:attr/borderlessButtonStyle"
        android:text="    从相册选择"/>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_height="1dp"

        android:background="#F4F2F2"
        >
    </LinearLayout>
    <Button
        android:id="@+id/btn_02"

        android:layout_height="55dp"
        android:layout_width="match_parent"
        android:textAlignment="textStart"
        style="?android:attr/borderlessButtonStyle"
        android:text="    拍照"/>
<LinearLayout
    android:layout_width="match_parent"

    android:layout_height="4dp"

    android:background="#F8F5F5"
    >


</LinearLayout>
    <Button
        android:id="@+id/btn_03"
        android:layout_height="55dp"
        android:layout_width="match_parent"
        style="?android:attr/borderlessButtonStyle"
        android:text="取消"/>

</LinearLayout>

2、在MainActivity.java中的代码

package com.guozijun.bottomsheet;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import com.google.android.material.bottomsheet.BottomSheetDialog;

public class MainActivity extends AppCompatActivity {
    private View bottom_popwindoow;
    private BottomSheetDialog mBottomSheetDialog;
    private Button btn;
    private Button btn_01;
    private Button btn_02;
    private Button btn_03;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        bottom_popwindoow = LayoutInflater.from(this).inflate(R.layout.bottom_popwindoow, null);
        mBottomSheetDialog = new BottomSheetDialog(this);
        mBottomSheetDialog.setContentView(bottom_popwindoow);
//show按钮
        btn = findViewById(R.id.mainButton1);
        btn.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View p1)
            {
                mBottomSheetDialog.show();
            }
        });
//从相册中选择按钮
        btn_01 =  mBottomSheetDialog.findViewById(R.id.btn_01);
        btn_01.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View p1)
            {
                Toast.makeText(MainActivity.this, "从相册选择", Toast.LENGTH_SHORT).show();
            }
        });
//拍照按钮
        btn_02 =  mBottomSheetDialog.findViewById(R.id.btn_02);
        btn_02.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View p1)
            {
                Toast.makeText(MainActivity.this, "拍照", Toast.LENGTH_SHORT).show();

            }
        });
//取消按钮
        btn_03 =  mBottomSheetDialog.findViewById(R.id.btn_03);
        btn_03.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View p1)
            {
                mBottomSheetDialog.dismiss();
            }
        });


    }

    }
