取值

public class PersonView extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  TextView text = new TextView(this);
  Person person = (Person)getIntent().getSerializableExtra("person");
  text.setText("name:"+person.getName()+"/nage:"+person.getAge()+"/n");
  setContentView(text);
 }
}
 

取值

public class BookView extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  TextView text = new TextView(this);
  Book book = (Book) getIntent().getParcelableExtra("book");
  text.setText("name:"+book.getName()+"/nautor:"+book.getAuthor()+"/ntime:"+book.getTime());
  setContentView(text);
 }
