通过Intent传递对象

Serializable序列化

只需要继承Seriablizable这个接口即可

person.java
自定义的对象，用来被intent传输

public class person implements Serializable {
    private String name;


    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

MainActivity.java

public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        person p = new person();
        p.setName("小明");
        Intent intent = new Intent("secondactivity");
        intent.putExtra("person_data", p);
        startActivity(intent);
    }
}

secondactivity.java

        person p = (person) getIntent().getSerializableExtra("person_data");
        Log.e("name", p.getName());

Parcelable

将自定义的对象进行拆分，拆成每个部分intent都支持传输即可
