本文实例为大家分享了Android实现简单用户注册的具体代码，供大家参考，具体内容如下
目标： 设计一个用户注册案例。在主界面中对输入的手机号、密码、性别、爱好和城市后，可以在界面二中进行显示。
提示：
1、页面布局的元素用到TextView、EditText、Button、RadioButton、CheckBox、Spinner；
2、通过intent实现主界面跳转到界面二
3、涉及传递多个的数据时，使用Bundle对象作为容器，通过调用Bundle的putString先将数据存储到Bundle中，然后调用Intent的putExtras()方法将Bundle存入Intent中，然后获得Intent后， 调用getExtras()获得Bundle容器，然后调用其getString获取对应的数据！
Bundle bundle=new Bundle();
bundle.putString("phone",phone_str);
bundle.putString("paswd",paswd_str);
bundle.putString("sex",sex_str);
bundle.putString("hobby",hobby_str);
bundle.putString("city",city_str);
//为意图追加额外的数据，意图原来已经具有的数据不会丢失，但key同名的数据会被替换
intent.putExtras(bundle);
//取得启动该Activity的Intent对象
Intent intent=this.getIntent();
Bundle bundle=intent.getExtras();
/*取出Intent中附加的数据*/
String phOne=bundle.getString("phone");
String paswd=bundle.getString("paswd");
String sex=bundle.getString("sex");
String hobby=bundle.getString("hobby");
String city=bundle.getString("city");
界面显示如下：
实现如下：
activity_main.xml
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
activity_second.xml
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
MainActivity.java
package com.example.jinjin.applicationtest4;
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.IdRes;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.Spinner;
public class MainActivity extends AppCompatActivity implements View.OnClickListener,RadioGroup.OnCheckedChangeListener{
//定义字符串用来保存各个信息
private String phone_str="";
private String paswd_str="";
private String sex_str="男";
private String hobby_str="1";
private String city_str="";
//组件定义
EditText phone_edit,paswd_edit;
RadioGroup sex_group;
RadioButton nan_but,nv_but;
CheckBox play,read,music;
Button register;
Spinner spinner;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//初始化组件
phone_edit = (EditText) findViewById(R.id.phone);
paswd_edit=(EditText)findViewById(R.id.paswd);
sex_group=(RadioGroup)findViewById(R.id.sex);
//添加监听事件
nan_but=(RadioButton)findViewById(R.id.nan);
sex_group.setOnCheckedChangeListener(this);
read=(CheckBox)findViewById(R.id.read_book);
play=(CheckBox)findViewById(R.id.play_ball);
music=(CheckBox)findViewById(R.id.music);
register=(Button)findViewById(R.id.register);
//添加监听事件
register.setOnClickListener(this);
spinner=(Spinner)findViewById(R.id.spinner);
// 创建ArrayAdapter对象
final String[] city=new String[]{"南宁","桂林","百色","柳州","玉林","河池"};
ArrayAdapter adapter=new ArrayAdapter(this,android.R.layout.simple_list_item_1,city);
spinner.setAdapter(adapter);
//城市下拉单列表添加监听事件
spinner.setOnItemSelectedListener(new Spinner.OnItemSelectedListener(){
@Override
public void onItemSelected(AdapterView<&＃63;> adapterView, View view, int i, long l) {
city_str=city[i];
}
@Override
public void onNothingSelected(AdapterView<&＃63;> adapterView) {
//未选中状态
}
});
}
@Override
public void onClick(View view) {
switch (view.getId()){
case R.id.register:
//获取手机号和密码
phone_str=phone_edit.getText().toString();
paswd_str=paswd_edit.getText().toString();
//获取兴趣爱好即复选框的值
hobby_str="";//清除上一次已经选中的选项
if (read.isChecked()){
hobby_str+=read.getText().toString();
}if(play.isChecked()){
hobby_str+=play.getText().toString();
}if(music.isChecked()){
hobby_str+=music.getText().toString();
}
Intent intent=new Intent(this,SecondActivity.class);
Bundle bundle=new Bundle();
bundle.putString("phone",phone_str);
bundle.putString("paswd",paswd_str);
bundle.putString("sex",sex_str);
bundle.putString("hobby",hobby_str);
bundle.putString("city",city_str);
intent.putExtras(bundle);
startActivity(intent);
break;
}
}
@Override
public void onCheckedChanged(RadioGroup radioGroup, @IdRes int i) {
//根据用户选择来改变sex_str的值
sex_str=i==R.id.nan&＃63;"男性":"女性";
}
}
SecondActivity.java
package com.example.jinjin.applicationtest4;
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
/**
* Created by jinjin on 2020/5/23.
*/
public class SecondActivity extends AppCompatActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
Intent intent=this.getIntent();
Bundle bundle=intent.getExtras();
String phOne=bundle.getString("phone");
String paswd=bundle.getString("paswd");
String sex=bundle.getString("sex");
String hobby=bundle.getString("hobby");
String city=bundle.getString("city");
TextView show_text=(TextView)findViewById(R.id.show_content);
show_text.setText("手机号为："+phone+"\n"+"密码为："+paswd+"\n"+"性别是："+sex+"\n"+"爱好是："+hobby+"\n"+"城市是："+city);
}
}
巩固监听事件:如果要对register和spinne的监听事件改造方法，如何重新实现监听？
实现如下
package com.example.jinjin.applicationtest4;
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.IdRes;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.Spinner;
public class MainActivity extends AppCompatActivity implements RadioGroup.OnCheckedChangeListener,AdapterView.OnItemSelectedListener{
//定义字符串用来保存各个信息
private String phone_str = "";
private String paswd_str = "";
private String sex_str = "男";
private String hobby_str = "1";
private String city_str = "";
//组件定义
EditText phone_edit, paswd_edit;
RadioGroup sex_group;
RadioButton nan_but, nv_but;
CheckBox play, read, music;
Button register;
Spinner spinner;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//初始化组件
phone_edit = (EditText) findViewById(R.id.phone);
paswd_edit = (EditText) findViewById(R.id.paswd);
sex_group = (RadioGroup) findViewById(R.id.sex);
//添加监听事件
nan_but = (RadioButton) findViewById(R.id.nan);
sex_group.setOnCheckedChangeListener(this);
read = (CheckBox) findViewById(R.id.read_book);
play = (CheckBox) findViewById(R.id.play_ball);
music = (CheckBox) findViewById(R.id.music);
register = (Button) findViewById(R.id.register);
//添加监听事件
// register.setOnClickListener(this);
spinner = (Spinner) findViewById(R.id.spinner);
//直接new一个内部类对象作为参数
register.setOnClickListener(new mclick());
// final String[] city=new String[]{"南宁","桂林","百色","柳州","玉林","河池"};
// ArrayAdapter adapter=new ArrayAdapter(this,android.R.layout.simple_list_item_1,city);
// spinner.setAdapter(adapter);
// //城市下拉单列表添加监听事件
// spinner.setOnItemSelectedListener(new Spinner.OnItemSelectedListener(){
// @Override
// public void onItemSelected(AdapterView<&＃63;> adapterView, View view, int i, long l) {
// city_str=city[i];
// }
// @Override
// public void onNothingSelected(AdapterView<&＃63;> adapterView) {
// }
// });
//Spinner加载监听事件
spinner.setOnItemSelectedListener(this);
}
@Override
public void onItemSelected(AdapterView<&＃63;> adapterView, View view, int i, long l) {
city_str=MainActivity.this.getResources().getStringArray(R.array.city)[i];
}
@Override
public void onNothingSelected(AdapterView<&＃63;> adapterView) {
}
//定义一个内部类,实现View.OnClickListener接口,并重写onClick()方法
class mclick implements View.OnClickListener {
@Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.register:
//获取手机号和密码
phone_str = phone_edit.getText().toString();
paswd_str = paswd_edit.getText().toString();
//获取兴趣爱好即复选框的值
hobby_str = "";//清除上一次已经选中的选项
if (read.isChecked()) {
hobby_str += read.getText().toString();
}
if (play.isChecked()) {
hobby_str += play.getText().toString();
}
if (music.isChecked()) {
hobby_str += music.getText().toString();
}
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
Bundle bundle = new Bundle();
bundle.putString("phone", phone_str);
bundle.putString("paswd", paswd_str);
bundle.putString("sex", sex_str);
bundle.putString("hobby", hobby_str);
bundle.putString("city", city_str);
intent.putExtras(bundle);
startActivity(intent);
break;
}
}
}
@Override
public void onCheckedChanged(RadioGroup radioGroup, @IdRes int i) {
//根据用户选择来改变sex_str的值
sex_str = i == R.id.nan &＃63; "男性" : "女性";
}
}
在res/values下编写一个：array.xml文件，内容如下：
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>- 南宁
- 桂林
- 柳州
- 百色
- 河池
- 玉林
