在Android中使用GSON解析一个复杂的JSON对象 [英] Using GSON in Android to parse a complex JSON object

问题描述

我是比较新的Java编程和需要解析跨线复杂的JSON对象。我一直在阅读上GSON文档过去一天，还没有多少运气能够完全分析这种类型的结构：

I'm relatively new to Java programming and need to parse a complex JSON object across the wire. I've been reading documentation on GSON the past day and Haven't had much luck being able to fully parse this type of structure:

{
  'Events' : [{
    'name' : 'exp',
    'date' : '10-10-2010',
    'tags' : ["tag 1", "tag2", "tag3"]
    },...more events...],
  'Contacts' : [{
    'name' : 'John Smith',
    'date' : '10-10-2010',
    'tags' : ["tag 1", "tag2", "tag3"]
    },...more contacts...],
}

我已经能够得到它的工作类似于这个的问题，但无法弄清楚如何获得附加阵列级的工作。

I've been able to get it to work similarly to this question but can't figure out how to get that additional array level to work.

推荐答案

在我找的格式使用GSON做正确的方法是：

The correct way to do it using GSON in the format I'm looking for is:

//somewhere after the web response:
Gson gson = new Gson();

Event[] events = gson.fromJson(webServiceResponse,  Event[].class);


//somewhere nested in the class:
static class Event{
    String name;
    String date;

    public String getName()
    {
        return name;
    }

    public String getDate()
    {
        return date;
    }

    public void setName(String name)
    {
        this.name = name;
    }

    public void setDate(String date)
    {
        this.date = date;
    }
}
