处理注册信息的小例子（bundle传递数据）

1.所包含的Activity共两个MainActivity，ResultActivity，一个Person类

package com.cbg.bundle;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.RadioButton;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button bn = (Button) findViewById(R.id.bn);
bn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
EditText name = (EditText) findViewById(R.id.name);
EditText pssword = (EditText) findViewById(R.id.password);
RadioButton male = (RadioButton) findViewById(R.id.male);
String gender = male.isChecked() ? "男" : "女";
Person p = new Person(name.getText().toString(), pssword
.getText().toString(), gender);
Bundle data = new Bundle();
data.putSerializable("person", p);
Intent intent = new Intent(MainActivity.this,
ResultActivity.class);
intent.putExtras(data);
startActivity(intent);

}
});

}
}

package com.cbg.bundle;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;

public class ResultActivity extends Activity {
TextView name, password, gender;

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.result);
name = (TextView) findViewById(R.id.name);
password = (TextView) findViewById(R.id.passwordo);
gender = (TextView) findViewById(R.id.gender);
// 获取启动该result的Internet
Intent intent = getIntent();
// 直接通过Intent去除他所携带的Bundle数据包中的数据
Person person = (Person) intent.getSerializableExtra("person");
name.setText("您的用户名为：" + person.getName());
password.setText("您的用户名为：" + person.getPassword());
gender.setText("您的用户名为：" + person.getGender());

}
}

package com.cbg.bundle;

import java.io.Serializable;

public class Person implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
/**
*
*/
String name;
String password;
String gender;

public Person(String name, String password, String gender) {
super();
this.name = name;
this.password = password;
this.gender = gender;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public String getGender() {
return gender;
}

public void setGender(String gender) {
this.gender = gender;
}

}

2,

a.创建person对象，用来存储数据注册信息;

b.创建bundle对象，用来存储person数据；

c.将person数据闯入bundle中并命名为person;

d.创建一个intent用作页面跳转;

e.将bundle传入intent中;

f.启动intent;

g.在ResultActivity中获取数据即可;

注意：ResultActivity不能忘了在Mainfest中注册;
