初学Android，这是一个用户登录界面，想把里面的值传递到另一个Activity中，先不说其他，上代码：
主界面（登录界面的Activity）：MainActivity.java
package com.zhoujunwen.widget;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.content.Intent;
import android.view.View.OnClickListener;
import android.widget.*;
public class MainActivity extends Activity {
//声明按钮Button
private Button register,cancle;
//声明ToggleButton
private ToggleButton marriged;
//声明单选按钮
private RadioButton male,female;
//声明文本编辑框
private EditText username,password;
//声明下拉列表
private Spinner position;
//声明多选按钮
private CheckBox reading,swimming;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//设置Activity页面布局
setContentView(R.layout.activity_main);
//通过findViewById获得EditText对象
username = (EditText)findViewById(R.id.username);
password = (EditText)findViewById(R.id.password);
//通过findViewById方法获得RadioButton
male = (RadioButton)findViewById(R.id.male);
female =(RadioButton)findViewById(R.id.female);
//通过findViewById获得ChechBox
reading =(CheckBox)findViewById(R.id.reading);
swimming =(CheckBox)findViewById(R.id.swimming);
//通过findViewById获得ToggleButton实例
marriged =(ToggleButton)findViewById(R.id.marriged);
//通过findViewById获得Spinner实例
position =(Spinner)findViewById(R.id.position);
//下拉列表选项
String[] str = {"CEO","CFO","PM"};
//数组下拉列表适配器
ArrayAdapter aa= new ArrayAdapter(this,android.R.layout.simple_spinner_item,str);
//设置下拉列表适配器
position.setAdapter(aa);
//通过findViewById方法获得Button的实例
register = (Button)findViewById(R.id.register);
cancle =(Button)findViewById(R.id.cancle);
//添加按钮的单击事件监听器
register.setOnClickListener(new OnClickListener(){
//点击事件方法
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Bundle b= new Bundle();
//在Bundle中添加用户名称和用户密码
b.putString("username", "用户名称："+username.getText().toString());
b.putString("password", "用户密码："+password.getText().toString());
//在Bundle中添加性别
if(male.isChecked()){
b.putString("gender","性别：男");
}else{
b.putString("gender","性别：女");
}
String temp= "爱好：";
if(reading.isChecked()){
temp+=" ";
temp+="阅读";
}
if(swimming.isChecked())
{
temp+=" ";
temp+="游泳";
}
//在Bundle中添加爱好
b.putString("hobby",temp);
//在Bundle中添加婚否
if(marriged.isChecked()){
b.putString("marriged","婚否：已婚");
}else{
b.putString("marriged","婚否：未婚");
}
//在Bundle添加职位
b.putString("position","职位："+position.getSelectedItem().toString());
//实例化Intent,跳转到ResultActivity
Intent intent = new Intent(MainActivity.this,ResultActivity.class);
//讲Bundle添加到Intent
intent.putExtra("data", b);
//启动Activity
startActivity(intent);
}
});
}
}
步骤：①获取Spinner的实例
②产生下拉列表数组
③数组适配器
④设置下拉列表适配器
代码：
//通过findViewById获得Spinner实例
position =(Spinner)findViewById(R.id.position);
//下拉列表选项
String[] str = {"CEO","CFO","PM"};
//数组下拉列表适配器
ArrayAdapter aa= new ArrayAdapter(this,android.R.layout.simple_spinner_item,str);
//设置下拉列表适配器
position.setAdapter(aa);步骤：①实例化Bundle对象，保存属性
②调用Bundle的putString(key,value)方法，把属性保存到key里面
③实例化Intent，这是Android传递值得信使，没有它不行
④调用Intent的putExtra(key,value),这儿value换成Bundle的实例
⑤启动该Activity。调用方法startActivity(③中实例化Intent的对象)
代码：
Bundle b= new Bundle();
//在Bundle中添加用户名称和用户密码
b.putString("username", "用户名称："+username.getText().toString());
b.putString("password", "用户密码："+password.getText().toString());
//在Bundle中添加性别
if(male.isChecked()){
b.putString("gender","性别：男");
}else{
b.putString("gender","性别：女");
}
String temp= "爱好：";
if(reading.isChecked()){
temp+=" ";
temp+="阅读";
}
if(swimming.isChecked())
{
temp+=" ";
temp+="游泳";
}
//在Bundle中添加爱好
b.putString("hobby",temp);
//在Bundle中添加婚否
if(marriged.isChecked()){
b.putString("marriged","婚否：已婚");
}else{
b.putString("marriged","婚否：未婚");
}
//在Bundle添加职位
b.putString("position","职位："+position.getSelectedItem().toString());
//实例化Intent,跳转到ResultActivity
Intent intent = new Intent(MainActivity.this,ResultActivity.class);
//讲Bundle添加到Intent
intent.putExtra("data", b);
//启动Activity
startActivity(intent);package com.zhoujunwen.widget;

import java.util.List;
import android.app.Activity;

public class ResultActivity extends Activity{
//声明ListView
private ListView listView;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//设置当前Activity界面布局
setContentView(R.layout.result);
//通过findViewById方法获得ListView对象
listView=(ListView)findViewById(R.id.ListView01);
//获得Intent

//从Intent中获得Bundle

list.add(b.getString("password"));
