添加依赖：

compile 'com.google.code.gson:gson:2.2.4'

通过将获取的json数据解析

httputil封装：

public static String sendGet( String code,String time) {
    String url="https://way.jd.com/jisuapi/query3";
    String result = "";
    BufferedReader in = null;
    try {
        String urlNameString = "https://way.jd.com/jisuapi/query3?caipiaoid=13&issueno=2014127&appkey=d3a62ea686a062d5a5ba1b91fda4f1df";
        URL realUrl = new URL(urlNameString);
        // 打开和URL之间的连接
        URLConnection connection = realUrl.openConnection();
        // 设置通用的请求属性
        connection.setRequestProperty("accept", "*/*");
        connection.setRequestProperty("connection", "Keep-Alive");
        connection.setRequestProperty("user-agent",
                "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
        // 建立实际的连接
        connection.connect();
        // 获取所有响应头字段
        Map<String, List<String>> map = connection.getHeaderFields();
        // 遍历所有的响应头字段
        for (String key : map.keySet()) {
            System.out.println(key + "--->" + map.get(key));
        }
        // 定义 BufferedReader输入流来读取URL的响应
        in = new BufferedReader(new InputStreamReader(
                connection.getInputStream()));
        String line;
        while ((line = in.readLine()) != null) {
            result += line;
        }
    } catch (Exception e) {
        System.out.println("发送GET请求出现异常！" + e);
        e.printStackTrace();
    }
    // 使用finally块来关闭输入流
    finally {
        try {
            if (in != null) {
                in.close();
            }
        } catch (Exception e2) {
            e2.printStackTrace();
        }
    }
    return result;
}

获取的json数组：{"code":"10000","charge":false,"msg":"查询成功","result":{"msg":"ok","result":{"number":"05 07 10 18 19 21 27","refernumber":"28","saleamount":"7482530","caipiaoid":"13","opendate":"2014-10-29","totalmoney":"","issueno":"2014127","deadline":"2014-12-27","prize":[{"num":"0","singlebonus":"0","require":"中7+0","prizename":"一等奖"},{"num":"9","singlebonus":"27603","require":"中6+1","prizename":"二等奖"},{"num":"245","singlebonus":"2028","require":"中6+0","prizename":"三等奖"},{"num":"773","singlebonus":"200","require":"中5+1","prizename":"四等奖"},{"num":"8165","singlebonus":"50","require":"中5+0","prizename":"五等奖"},{"num":"14423","singlebonus":"10","require":"中4+1","prizename":"六等奖"},{"num":"95000","singlebonus":"5","require":"中4+0","prizename":"七等奖"},{"num":"0","singlebonus":"0","require":"中4+0","prizename":""}]},"status":"0"}}

使用GsonFormat格式，生成Bean类

AS里面有插件，这里不做多述

开始解析：

private void getData(final String code, final String time) {
    new Thread(new Runnable() {
        @Override
        public void run() {
            json = HttpUtil.sendGet(code, time).replace("\\", "");
            runOnUiThread(run);
        }
    }).start();
}

Runnable run = new Runnable() {
    @Override
    public void run() {
        Gson gson = new Gson();
        CaiPiao resultBeanX1 = gson.fromJson(json, CaiPiao.class);
        Log.i("TAG==========", json);
        qishu.setText(resultBeanX1.getResult().getResult().getIssueno());
        haoma.setText(resultBeanX1.getResult().getResult().getNumber());
        xiaoshoujine.setText(resultBeanX1.getResult().getResult().getSaleamount());
        jiangchijine.setText(resultBeanX1.getResult().getResult().getTotalmoney());
    }
};

坑来了：Gson解析Json数据首先得从最外层进行解析，否则会看不到数据
