您可以找到JSON教程在Android

you can find "json tutorials" on android

你要做的第一件事就是获得响应文本。

first thing you have to do is to get the response text.

private String getResponseText(String stringUrl) throws IOException
{
    StringBuilder response  = new StringBuilder();

    URL url = new URL(stringUrl);
    HttpURLConnection httpconn = (HttpURLConnection)url.openConnection();
    if (httpconn.getResponseCode() == HttpURLConnection.HTTP_OK)
    {
        BufferedReader input = new BufferedReader(new InputStreamReader(httpconn.getInputStream()),8192);
        String strLine = null;
        while ((strLine = input.readLine()) != null)
        {
            response.append(strLine);
        }
        input.close();
    }
    return response.toString();
}

在这之后，你将采取的应对文本，并解析它作为一个JSON根对象，像这样

In which after that you will take the response text and parse it as a json root object like so

String responseText = GetResponseText(requestUrl);
JSONObject mainResponseObject = new JSONObject(responseText);

和然后根据你以下类解析的JSONObject的数据的结构：
    的JSONObject JSONArray

and then according to the structure of the data you parse the JSONObject with the following classes: JSONObject JSONArray

和使用的类中定义的get方法获取值，检查他们的文件上。

and get the values using the get methods defined on the classes, check them on the documentation.

http://developer.android.com/reference/org/json/ JSONObject.html

有很多在网上例子并搜寻他们。

there are a lot of examples on the net do search for them..
