import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.CheckBox;

import android.widget.CompoundButton;

import android.widget.Toast;

public class CheckBoxActivity extends AppCompatActivity {

private CheckBox mCb4,mCb5,mCb6;//声明

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_check_box);

mCb4 = findViewById(R.id.Cb_4);//绑定

mCb5 = findViewById(R.id.Cb_5);//绑定

mCb6 = findViewById(R.id.Cb_6);//绑定

mCb4.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

@Override

public void onCheckedChanged(CompoundButton compoundButton, boolean b) {

//设置监听事件

Toast.makeText(CheckBoxActivity.this, b?"4选中":"4未选中", Toast.LENGTH_SHORT).show();

}

});

mCb5.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

@Override

public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
