4 两个Activity间通过Bundle传递数据

------------------------------main.java------------------------------------

//Person是一个普通的javaBean

Person person = new Person(名字, 密码);

//创建一个Bundle对象

Bundle bundle = new Bundle();

bundle.putSerializable("person", person);

Intent intent = new Intent(MainActivity.this,
OtherActivity.class);

intent.putExtras(bundle);

startActivity(intent);

---------------------------------------OtherActivity.java--------------------------

//获取启动该Result的Intent

Intent intent = getIntent();

//直接通过Intent取出它所携带的Bundle数据包的数据

Person person = (Person) intent.getSerializableExtra("person");
