Android隐性传值初识

1、传送端代码

 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);    }

2、接收端接受全送过来的值

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());    }

3、注意选择serializable接口可以传送一对象
4、隐性传值必须在xmlz这样写

<activity android:name=".Main2Activity">            <intent-filter>                <action android:name="user1"></action>                <category android:name="android.intent.category.DEFAULT"></category>            </intent-filter>        </activity>

上面是今天自己下课摸索的，晚上回去再写点其他难一点的。
