Android(安卓)使用Parcelable接口

package com.example.AndroidStudy;import android.os.Parcel;import android.os.Parcelable;public class Person  implements Parcelable{  private String name;  private   int age;  public Person(String name, int age) {    this.name = name;    this.age = age;  }  public String getName() {    return name;  }  public void setName(String name) {    this.name = name;  }  public int getAge() {    return age;  }  public void setAge(int age) {    this.age = age;  }  //重写下面两个方法  @Override  public int describeContents() {    return 0;  }  @Override  public void writeToParcel(Parcel dest, int flags) {    //把数据写入Parcel    dest.writeString(name);    dest.writeInt(age);  }  //还必须含有一个名称为CREATOR的静态成员，该成员对象要求实现Parcelable.Creator接口及其方法  public static final  Creator<Person>CREATOR=new Creator<Person>() {    @Override    public Person createFromParcel(Parcel source) {      //读取时返回Person对象---根据Parcel写入的数据生成Person返回      return new Person(source.readString(), source.readInt());    }    @Override    public Person[] newArray(int size) {      return new Person[size];    }  };}

使用 Bundle.putParcelable()方法把自定义Person数据放入Bundle内

Intent intent1=new Intent(MyActivity.this,SecondActivity.class);Bundle bundle=new Bundle();bundle.putString("title","Activity 2");bundle.putParcelable("person",new Person("小白",20));intent1.putExtras(bundle);startActivity(intent1);

//获取bundle数据 Bundle bundle=getIntent().getExtras(); String text=bundle.getString("title");//根据key来获取 Person person=(Person)bundle.getParcelable("person");
