如何把在Parcelable Location对象 [英] how to put a Location object in Parcelable

问题描述

我在实现Parcelable我的其他场馆对象的一个​​Location对象。如何在我的writeToParcel方法实现正确序列化呢？因此，这里的一些code：

 公共类场馆实现Parcelable {
    公共字符串ID;
    公共字符串名称;
    公共字符串的地址;
    公共场所的位置;
    公共字符串的城市;
    公共字符串状态;
    公共字符串的国家;
    公共字符串邮政code;

    @覆盖
    公众诠释describeContents（）{
        // TODO自动生成方法存根
        返回0;
    }

    @覆盖
    公共无效writeToParcel（宗地递减，INT标志）{
        desc.writeString（ID）;
        desc.writeString（州）;
        desc.writeString（名称）;
        desc.writeString（地址）;
        desc.writeString（邮政code）;
        desc.writeString（国家）;
        desc.writeString（市）;
        //我仍然失踪的方式在这里连载我的地址对象
    }
}
 

解决方案

在这里，你有一个片段如何parcable对象序列化到自己的包裹。

 地点的位置;

公共无效writeToParcel（宗地递减，INT标志）{
    location.writeToParcel（DESC，旗）;
    / *在这里做你的其他包裹的东西* /
}

公共无效readFromParcel（包裹中）{
    位置= Location.CREATOR.createFromParcel（中）;
    / *在这里做你的其他包裹的东西* /
}
 

I have a Location object in one of my other Venue object that implements Parcelable. How do I serialize this correctly in my writeToParcel method implementation? So here's some code:

public class Venue implements Parcelable{
    public String id;
    public String name;
    public String address;
    public Location location;
    public String city;
    public String state;
    public String country;
    public String postalCode;

    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public void writeToParcel(Parcel desc, int flags) {
        desc.writeString(id);
        desc.writeString(state);
        desc.writeString(name);
        desc.writeString(address);
        desc.writeString(postalCode);
        desc.writeString(country);
        desc.writeString(city);
        //I am still missing on a way to serialize my Location object here
    }
}

解决方案

Here your have a snippet how to serialize parcable objects into your own parcel.

Location location;

public void writeToParcel(Parcel desc, int flags) {
    location.writeToParcel(desc, flags);
    /* do your other parcel stuff here */
}

public void readFromParcel(Parcel in) {
    location=Location.CREATOR.createFromParcel(in);
    /* do your other parcel stuff here */
}
