我是JSON的新手，请尝试使用本教程：http : //p-xr.com/android-tutorial-
how-to-parse-read-json-data-into-a-android-
listview/#comments

我是JSON，C语言，Java和Android的新手，但我正在学习。本教程使用的是我所说的命名数组，但是我将在我的android项目中使用的所有JSON将使用没有命名数组的简单表行。我正在使用的JSON和教程中的地震json的示例如下。

本教程遍历地震数组，并使用以下代码将其转换为JAVA哈希图列表：

JSONArray  earthquakes = json.getJSONArray("earthquakes");
    for(int i=0;i<earthquakes.length();i++){                        
        HashMap<String, String> map = new HashMap<String, String>();    
        JSONObject e = earthquakes.getJSONObject(i);

        map.put("id",  String.valueOf(i));
        map.put("name", "Earthquake name:" + e.getString("eqid"));
        map.put("magnitude", "Magnitude: " +  e.getString("magnitude"));
        mylist.add(map);            
}

我的问题是，json.getJSONArray("")如果我的JSON如下所示，该如何使用？我可以转换其余的代码，getJSONArray("strJsonArrayName")如果我没有，我只需要知道如何使用来加载JSON
strJsonArrayName。

我的JSON（未命名数组）

[
  {
    "cnt":1,
    "name":"American",
    "pk":7
  },
  {
    "cnt":2,
    "name":"Celebrities",
    "pk":3
  },
  {
    "cnt":1,
    "name":"Female",
    "pk":2
  },
  {
    "cnt":1,
    "name":"Language",
    "pk":8
  },
  {
    "cnt":1,
    "name":"Male",
    "pk":1
  },
  {
    "cnt":1,
    "name":"Region",
    "pk":9
  }
]

教程的JSON（命名数组）

在本教程中，基于@MДΓΓБДLL和@Cody
Caughlan的答案，我能够将JSONFunctions.getJSONFromURL格式化为JSONArray而不是JSONObject。这是我修改后的工作代码，谢谢！

public class JSONfunctions {
public static JSONArray getJSONfromURL(String url){
    InputStream is = null;
    String result = "";
    JSONArray jArray = null;

            HttpClient httpclient = new DefaultHttpClient();
            HttpGet httpget = new HttpGet(url);
            HttpResponse response = httpclient.execute(httpget);
            HttpEntity entity = response.getEntity();
            is = entity.getContent();

            BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                    sb.append(line + "\n");
            }
            is.close();
            result=sb.toString();

        jArray = new JSONArray(result);            
    return jArray;
}
}
