Serializable的基本使用:

新建對(duì)象: 使用serializable的接口
public class 類名 implements Serializable
{
     private static final long serializableVersionUID=9092013023902193012930L;
     .....
 }

調(diào)用:

//序列化過(guò)程:
類  新建一個(gè)對(duì)象;
ObjectOutputStream os=new ObjectOutputStream(new FileOutputStream(path));
os.writeObject(對(duì)象);
os.close();

//反序列化
ObjectInputStream in=new ObjectInputStream(new FileInputStream(path));
對(duì)象=in.readObject();
in.close();

在android中,Serializable可以用于Intent的對(duì)象傳遞。

public class User implements Serializable
{
     private static final long serializableVersionUID=328379124090932959045094095L;
    public int age;
    public String name;
    public int id;
}
  
private Button button;
private User ololee=new User();
 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button=(Button)findViewById(R.id.button);
        //ololee->init....balabala
        button.setOnClickListerner(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(MainActivity.this,SecondActivity.class);
                intent.putExtra("user",ololee);
                startActivity(intent);
            }
        });
    }

Intent傳遞數(shù)據(jù)有四種方式:

0x01:常用類型數(shù)據(jù)使用Intent.putExtra();使用相應(yīng)的getIntent().getExtra()方法得到數(shù)據(jù)
0x02:Bundle傳遞
0x03:Serializable傳遞
0x04:Parcelable傳遞
