解决方案
您是误会了JSON序列化方式的对象。基本上，（非常基本） {...} 是对象， [...，...] 是数组和键：值是对象的属性，所以是这样的：
{
responseData：{
结果：[]，
光标： {
moreResultsUrl：http://www.url.com，
searchResultTime：0,00
}
}，
responseDetails：空，
responseStatus：200
}
意味着你必须有3个属性的第一个目的： responseData （对象）， responseDetails （null对象）和 responseStatus （INT）。而 responseData 是一个对象，具有2个属性：结果（阵列），光标（对象）。而光标的属性 moreResultsUrl （串），而 searchResultTime （串）。
现在，来解析JSON，你可以尝试这样的：
- 您可以在您的code提供太克隆 - 从-教程头脑。你将不得不修改的东西多一点，以保持一定的等级参数命名的（你的变量谈论车和你对网络搜索的数据...）。你可以重命名ListAdapter适配器=新的简单的... 的方法，以满足您的需求，从
的一些数据。
**为了使用这些JSON方法，你需要包含简单的JSON库。

解决方案
You are misunderstanding the way json serializes objects. Basically (very basically) {...} are objects, [...,...] are arrays and key:value are object properties, so something like:
{
"responseData": {
"results": [],
"cursor": {
"moreResultsUrl": "http://www.url.com",
"searchResultTime": "0,00"
}
},
"responseDetails": null,
"responseStatus": 200
}
Means that you have a first object that has 3 properties: responseData(object), responseDetails(null object) and responseStatus(int). And responseData is an object with 2 properties: results (array) and cursor(object). And cursor's properties are moreResultsUrl(string), and searchResultTime(string).
and now, for parsing the json you can try something like this:
- Take in mind that your code provided was too cloned-from-tutorial. You will have to edit things a little bit more in order to maintain some grade of parameter naming (your variables talk about cars and your data about web searches...). And you may rename some data from
ListAdapter adapter = new Simple...method in order to fit your needs.
** In order to use these JSON methods, you need to include the simple json library.
