这周学会了安卓checkbox的用法，用法代码如下。

package com.dongnaoedu.chapter05;

 

import androidx.appcompat.app.AppCompatActivity;

 

import android.os.Bundle;

import android.widget.CheckBox;

import android.widget.CompoundButton;

 

public class CheckBoxActivity extends AppCompatActivity implements CompoundButton.OnCheckedChangeListener {

 

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_check_box);

        CheckBox ck_system = findViewById(R.id.ck_system);

        CheckBox ck_custom = findViewById(R.id.ck_custom);

 

        ck_system.setOnCheckedChangeListener(this);

        ck_custom.setOnCheckedChangeListener(this);

    }

 

    @Override

    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

        String desc = String.format("您%s了这个CheckBox", isChecked ? "勾选" : "取消勾选");

        buttonView.setText(desc);

    }

}
