Android实现简单用户注册案例

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:

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<String> adapter=new ArrayAdapter<String>(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<?> adapterView, View view, int i, long l) {

city_str=city[i];

}

@Override

public void onNothingSelected(AdapterView<?> 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?"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?

  • register可使用内部类,并重写onClick()方法 。
  • spinner可使用实现接口的监听事件。

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<String> adapter=new ArrayAdapter<String>(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<?> adapterView, View view, int i, long l) {

// city_str=city[i];

// }

// @Override

// public void onNothingSelected(AdapterView<?> adapterView) {

// }

// });

//Spinner加载监听事件

spinner.setOnItemSelectedListener(this);

}

@Override

public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {

city_str=MainActivity.this.getResources().getStringArray(R.array.city)[i];

}

@Override

public void onNothingSelected(AdapterView<?> 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 ? "男性" : "女性";

}

}

在res/values下编写一个:array.xml文件,内容如下:

<?xml version="1.0" encoding="utf-8"?>

<resources>

<string-array name="city">

<item>南宁</item>

<item>桂林</item>

<item>柳州</item>

<item>百色</item>

<item>河池</item>

<item>玉林</item>

</string-array>

</resources>
