从一个活动转移目标到另一个活动

问题描述

我有一个类EmployeeInfo如下：

I am having a class EmployeeInfo as the following :

 public class EmployeeInfo {
        private int id; // Employee ID
        private String name; // Employee Name
        private int age;// Employee Age

        public int getEmployeeID() {
            return id;
        }

        public void setEmployeeID(int id) {
            this.id = id;
        }

        public String getEmployeeName() {
            return name;
        }

        public void setEmployeeName(String name) {
            this.name = name;
        }
        public int getAge() {
            return age;
        }

        public void setAge(int age) {
            this.age= age;
        }
    }


ArrayList<EmployeeInfo> employeeInfo object contains the emplyoyee info data for multiple employees.

我想从活动1中的数据（ArrayList中employeeInfo）转移到活性2。

I want to transfer the data( ArrayList employeeInfo ) from Activity1 to Activity2.

时使用Parcelable的数据传输活动1至活性2的唯一途径？如果不是，有什么办法。

Is using Parcelable the only way to transfer the data from Activity1 to Activity2?If not , what are the alternatives.

如果是，请连同有关如何将目标数据传输活动1至活性2样品code提供Parcelable的原型code。

If yes ,kindly provide the prototype code of Parcelable along with the sample code on how to transfer the object data from Activity1 to Activity2.

在此先感谢。

亲切问候，

推荐答案

下面是我实现Parceleble的：

Here is my implementation of Parceleble:

public class ProfileData implements Parcelable {

private int gender;
private String name;
private String birthDate;

public ProfileData(Parcel source) {
    gender = source.readInt();
    name = source.readString();
    birthDate = source.readString();
}

public ProfileData(int dataGender, String dataName, String dataBDate) {
    gender = dataGender;
    name = dataName;
    birthDate = dataBDate;
}

// Getters and Setters are here

@Override
public int describeContents() {
return 0;
}

@Override
public void writeToParcel(Parcel out, int flags) {
out.writeInt(gender);
out.writeString(name);
out.writeString(birthDate);
}

public static final Parcelable.Creator<ProfileData> CREATOR
      = new Parcelable.Creator<ProfileData>() {

public ProfileData createFromParcel(Parcel in) {
    return new ProfileData(in);
}

public ProfileData[] newArray(int size) {
    return new ProfileData[size];
}

};

}

和我是如何传输的数据：

and how I transfer data:

Intent parcelIntent = new Intent().setClass(ActivityA.this, ActivityB.class);
ProfileData data = new ProfileData(profile.gender, profile.getFullName(), profile.birthDate);
parcelIntent.putExtra("profile_details", data);
startActivity(parcelIntent);

和获取数据：

    Bundle data = getIntent().getExtras();
    ProfileData profile = data.getParcelable("profile_details");
