需求:MainActivity跳转到TestActivity并将ArrayLis作为参数传递。

1）类Student的代码如下：

package com.example.testa;import android.os.Parcel;import android.os.Parcelable;public class Student implements Parcelable{public Student(){}public Student (int _id, String _name){setId(_id);setName(_name);}private int id;private String name;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getId() {return id;}public void setId(int id) {this.id = id;}@Overridepublic int describeContents() {return 2;}@Overridepublic void writeToParcel(Parcel dest, int flags) {dest.writeInt(id);dest.writeString(name);}public static final Parcelable.Creator<Student> CREATOR =new Creator<Student>() {@Overridepublic Student createFromParcel(Parcel source){Student student = new Student();student.id=source.readInt();student.name=source.readString();return student;}@Overridepublic Student[] newArray(int size){return new Student[size];}};}

2）MainActivity跳转页面并传递参数的代码如下

/*生成参数对象*/ArrayList<Student> items=new ArrayList<Student>();Parcel parcel=Parcel.obtain();Student item1=Student.CREATOR.createFromParcel(parcel);item1.setId(1);item1.setName("chad.cao");items.add(item1);Student item2=Student.CREATOR.createFromParcel(parcel);item2.setId(2);item2.setName("catherine.yu");items.add(item2);parcel.recycle();    Intent intent=new Intent(MainActivity.this, TestActivity.class);    intent.putParcelableArrayListExtra("students", items);    this.startActivity(intent);

3）TestActivity中获取参数的代码如下

Bundle bundle=this.getIntent().getExtras();    ArrayList<Student> items=bundle.getParcelableArrayList("students");
