Android隐性传值初识

public void go(View view) {
Intent intent = new Intent();
Bundle bundle =  new Bundle();
User user = new User();
user.setAge(99);
user.setName("Li");
//  intent.putExtra("name","zhang");
//  intent.putExtra("age",100);

intent.setAction("user1");
bundle.putSerializable("user",user);
intent.putExtras(bundle);
startActivity(intent);
}

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
//Intent intent = this.getIntent();
//  String name = intent.getStringExtra("name");
// int age =    intent.getIntExtra("age", 120);
// Log.i("dong", "onCreate....main2..."+name+".."+age);
Intent intent =  this.getIntent();
User user = (User)intent.getSerializableExtra("user");
Log.i("dong", "onCreate....main2..."+user.getName()+".."+user.getAge());

}
