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();
            }
        });


    }

    }
