通过http://blog.youkuaiyun.com/vincent_czz/article/details/7333977，找到了自己所需要的，--->写的更全面，我写的是自己需要的部分 -----android菜鸟

json 语句：{
"state": "OK",
"type": [
{
"add_time": "2015-10-14",
"attr_id": "86",
"attr_name": "五金工具",
"image": "http://www.layib.com/data/files/marchine_type/9155151.jpg",
"parent_id": "79",
"sort_order": "255"
},
{
"add_time": "2015-10-26",
"attr_id": "87",
"attr_name": "市政园林",
"image": "http://www.layib.com/data/files/marchine_type/7042480.jpg",
"parent_id": "79",
"sort_order": "255"
},
{
"add_time": "2015-10-26",
"attr_id": "88",
"attr_name": "起重机械",
"image": "http://www.layib.com/data/files/marchine_type/7828002.jpg",
"parent_id": "79",

},
{

"attr_id": "90",
"attr_name": "路面设备",

"attr_id": "91",
"attr_name": "能源设备",

"parent_id": "79",
"sort_order": "255"
},
{
"add_time": "2015-10-26",
"attr_id": "92",
"attr_name": "路面设备",

使用的xutils获取的json语句

private List<String> getWuZiShaiXuanData(){
    List<String> wuziShaiXuanData = new ArrayList<>();

    HttpUtils httpUtils = new HttpUtils();

    httpUtils.send(HttpRequest.HttpMethod.GET, Utils.WUZI_ZULIN, new RequestCallBack<String>() {
        @Override
        public void onSuccess(ResponseInfo<String> responseInfo) {
            String result = responseInfo.result;

            try {
                JSONObject jsonObject = new JSONObject(result);

                JSONArray typeList = jsonObject.getJSONArray("type");

                int length = typeList.length();

                for (int i = 0;i<length;i++){
                    JSONObject oj = typeList.getJSONObject(i);

                    String name = (String) oj.get("attr_name");	

                    wuziShaiXuanData.add(name);
                }

                Toast.makeText(BaseActivity.this,wuziShaiXuanData.toString(),Toast.LENGTH_SHORT).show();

            } catch (JSONException e) {
                e.printStackTrace();
            }
        }

        @Override
        public void onFailure(HttpException e, String s) {

        }
    });

    return wuziShaiXuanData;
}

二.碰到的另一种json语句

{
    "state": "OK",
        "type": {
    "100": "xx组",
            "101": "xx组",
            "102": "xx组",
            "103": "xx组",
            "104": "xx组",
            "105": "xx组",
            "65": "xx组",
            "66": "xx组",
            "97": "xx组",
            "98": "xx组",
            "99": "xx组"
	}
}

我自己的解析方式：

httpUtils.send(HttpRequest.HttpMethod.GET, Utils.BANZU_TYPE, new RequestCallBack<String>() {
    @Override
    public void onSuccess(ResponseInfo<String> responseInfo) {

        String result = responseInfo.result;

        try {
            JSONObject jsonObject = new JSONObject(result);

            String result_type = jsonObject.getString("type");

            jsonObject = new JSONObject(result_type);

            Iterator<String> iterator = jsonObject.keys();

            while (iterator.hasNext()) {

                String key = iterator.next();

                String value = jsonObject.getString(key);

                banzuData.add(value);      // List<String> banzuData


                banzuDataTypeHashMap.put(value,key);

            }

        } catch (JSONException e) {
            e.printStackTrace();
        }

    }

    @Override
    public void onFailure(HttpException e, String s) {

    }
});
