多个Activity如何通过Intent传递Arraylist<object>

点击mainActivity中的按钮，把Arraylist<Person> mList传递给MainActivity2并在TextView显示出来。直接看代码：

public class Person implements Parcelable{//实现 Parcelable
    String name;
    int age;
    public Person(String name, int age) {
        super();
        this.name = name;
        this.age = age;
    }
//下面三个方法才是关键
    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    public static final Parcelable.Creator<Person> CREATOR = new Creator<Person>() 
            { 
                public Person createFromParcel(Parcel source) 
                { 
                    Person person = new Person("ccc", 12); 
                    person.name = source.readString(); 
                    person.age = source.readInt(); 
                    return person; 
                } 
                public Person[] newArray(int size) 
                { 
                    return new Person[size]; 
                } 
            }; 
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeInt(age);
                                                             
    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + age;
        result = prime * result + ((name == null) ? 0 : name.hashCode());
        return result;
    }
    @Override
    public String toString() {
        return "Person [name=" + name + ", age=" + age + "]";
    }
    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        Person other = (Person) obj;
        if (age != other.age)
            return false;
        if (name == null) {
            if (other.name != null)
                return false;
        } else if (!name.equals(other.name))
            return false;
        return true;
    }
    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;
    }
}

public class MainActivity extends Activity {
    private ArrayList<Person> mList;
    @Override

        Person person1 = new Person("aaa", 12);
        Person person2 = new Person("bbb", 21);
        mList.add(person1);
        mList.add(person2);
    }
    public void btnClick(View v) {//button点击事件
        Intent intent = new Intent(this, MainActivity2.class);
        Bundle bundle = new Bundle();
        bundle.putParcelableArrayList("mList", mList);

        mText = (TextView) findViewById(R.id.tv2);
        ArrayList<Person> serializable = (ArrayList<Person>) getIntent().getExtras().getSerializable("mList");
        mText.setText(serializable.toString());
    }
