使用android解析多个Json数组中的Json数组

如何使用多个数组创建JSON对象

我以前从未使用过JSON，所以我不熟悉它的语法。 问题是我不知道下一个数组名是什么。是否有可能解析来自所有数组的数据，而无需名称，也无需更改其结构？如何使用Volley解析多个JSON数组

JSON字符串由一个数组组成，其中包含数组，数组中包含对象。所以

// parse json to an array
JSONArray array = new JSONArray(jsonString);
// loop through that array and get nested arrays
for (int i = 0; i < array.length(); i++) {
     JSONArray subArray = array.getJSONArray(i);
     // loop trhough those nested arrays to retrieve the objects
     for (int j = 0; j < subArray.length(); j++) {
           JSONObject obj = subArray.getJsonObject(j);
           // parse the object properties...

     }
}
