填写注册信息页面:register.class
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button bn = (Button)findViewById(R.id.bn);
bn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
EditText name = (EditText)findViewById(R.id.name);
EditText pass = (EditText)findViewById(R.id.pass);
RadioButton male = (RadioButton)findViewById(R.id.male);
String gender = male.isChecked()?
"男":"女";
Bundle bundle = new Bundle();
person person = new person(name.getText().toString(), pass.getText().toString(), gender);
bundle.putSerializable("person", gender);
Intent intent = new Intent(MainActivity.this, sec.class);
intent.putExtras(bundle);
startActivity(intent);
}
});
}
获取注册信息页面sec.class

setContentView(R.layout.result);
TextView name = (TextView) findViewById(R.id.name);
TextView passwd = (TextView) findViewById(R.id.pass);
TextView gender = (TextView) findViewById(R.id.gender);
// 获取启动该Result的Intent
Intent intent = getIntent();
// 直接通过Intent取出它所携带的Bundle数据包中的数据
person p = (person) intent.getSerializableExtra("person");
name.setText("您的用户名为：" + p.getName());
passwd.setText("您的密码为：" + p.getPass());
gender.setText("您的性别为：" + p.getGender());
}

异常信息：
java,lang.runtimeexception:unable to start activity componentinfo{com.example,register/com.example,register.sec}:java.lang.classcastexception:java.lang.string cannot be cast to com.example.register.person
------解决思路----------------------
bundle.putSerializable("person", gender);这句改为bundle.putSerializable("person", person);
