您好，我无法对来自 Nodejs 服务器的以下多维 JsonArray 数据进行循环。

只要有更多数据进入，即使 jsonarray 的索引值也会动态增加。请帮我实现for循环来动态获取数据。

我从服务器得到的响应是:-

你可以试试这个方法

JSONArray array = yourJsonArrayFromServer;

for(int i = 0 ; i < array.length(); i++){
    // get current object with: array.getJSONObject(i)
    // do something
}

如果我很好地理解你的问题。
