安卓Android绘制一个信息填写页面，使用了三种事件监听方法

先上效果图片：

 

第一种，匿名内部类

//设置提交按钮监听
        submitButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                System.out.println("我是方法一");
                // 初始性别字符串
                String Sex = "";
                //循环单选组
                for (int i = 0; i < radioButton.getChildCount(); i++) {
                    RadioButton r = (RadioButton) radioButton.getChildAt(i);
                    if (r.isChecked()) {
                        Sex = r.getText().toString();
                        // 先LogCat测试一下
                        // System.out.println(Sex);
                        break;
                    }
                }

                // 初始化爱好字符串
                String userLove = "";
                if (checkBox1.isChecked()) {
                    userLove += (String) checkBox1.getText().toString() + " ";
                }
                if (checkBox2.isChecked()) {
                    userLove += (String) checkBox2.getText().toString() + " ";
                }
                if (checkBox3.isChecked()) {
                    userLove += (String) checkBox3.getText().toString() + " ";
                }
                System.out.println(userLove);

                // 广播
                Toast.makeText(MainActivity.this,
                        "你填写的信息如下\n" + "用户名：" + userName.getText()
                                + "\n密码：" + userPassword.getText()
                                + "\n性别：" + Sex
                                + "\n爱好:" + userLove,
                        Toast.LENGTH_LONG).show();
            }
        });

第二种，控件的事件属性绑定

            
                android:onClick="showInput"
                android:text="提交2" />

第三种，通过事件源所在类实现

 下面是完整的布局xml代码与主活动代码

package com.zt.myapplication;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;

/**
 * 2021.10.6
 * 设置提交按钮监听，点击按钮后，广播出用户填写的信息
 * Written by Zhong Tao
 */

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

    // 提交按钮
    Button submitButton;
    Button submitButton3;
    // 用户名输入框
    EditText userName;
    // 用户密码输入框
    EditText userPassword;
    // 性别单选框
    RadioGroup radioButton;
    // 爱好多选框
    CheckBox checkBox1;
    CheckBox checkBox2;
    CheckBox checkBox3;


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


        /**
         * 2021.10.6
         * 设置提交按钮监听，点击按钮后，广播出用户填写的信息
         * Written by Zhong Tao
         */

        //为对象赋值
        userName = findViewById(R.id.userNameInput);
        userPassword = findViewById(R.id.passwordInput);
        radioButton = (RadioGroup) findViewById(R.id.sexGroup);
        submitButton = findViewById(R.id.submit);
        submitButton3 = findViewById(R.id.submit3);
        //多选框数量
        int checkBoxNum = 3;
        checkBox1 = (CheckBox) findViewById(R.id.checkBox1);
        checkBox2 = (CheckBox) findViewById(R.id.checkBox2);
        checkBox3 = (CheckBox) findViewById(R.id.checkBox3);


        //设置提交按钮监听（内部类方式）
        submitButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                System.out.println("我是方法一");
                // 初始性别字符串
                String Sex = "";
                //循环单选组
                for (int i = 0; i < radioButton.getChildCount(); i++) {
                    RadioButton r = (RadioButton) radioButton.getChildAt(i);
                    if (r.isChecked()) {
                        Sex = r.getText().toString();
                        // 先LogCat测试一下
                        // System.out.println(Sex);
                        break;
                    }
                }

                // 初始化爱好字符串
                String userLove = "";
                if (checkBox1.isChecked()) {
                    userLove += (String) checkBox1.getText().toString() + " ";
                }
                if (checkBox2.isChecked()) {

                }
                if (checkBox3.isChecked()) {
                    userLove += (String) checkBox3.getText().toString() + " ";
                }
                System.out.println(userLove);

                // 广播
                Toast.makeText(MainActivity.this,
                        "你填写的信息如下\n" + "用户名：" + userName.getText()
                                + "\n密码：" + userPassword.getText()

                                + "\n爱好:" + userLove,
                        Toast.LENGTH_LONG).show();
            }
        });


        submitButton3.setOnClickListener(this);

    }


    //控件属性的事件监听方法
    public void showInput(View view) {
        System.out.println("我是方法二");
        // 初始性别字符串
        String Sex = "";
