如何使用 java 获取 json 中的数组?

How to get array in json using java?

请帮助我如何获取 xy 的值我已经尝试了下面的代码但它不起作用。我下面的代码错了吗?请帮我。提前致谢

Json 下面的例子

{"name":"room ko","lights":["3","2"],"type":"Room","state":{"all_on":true,"any_on":true},"recycle":false,"class":"Living room","action":{"on":true,"bri":254,"hue":34704,"sat":198,"effect":"none","xy":[0.3228,0.3291],"ct":167,"alert":"none","colormode":"xy"}

这里是我目前试过的代码。

  String message="";
  JSONArray jsonArray = null;
  try {
       JSONObject jsonObject = new JSONObject(s);
       message = jsonObject.getString("name");
       jsonArray = jsonObject.getJSONArray("xy");

       Log.d(TAG,jsonArray);//error in here

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

我猜你想:

jsonArray = jsonObject.getJSONObject("action").getJSONArray("xy");
