如何使用多个数组制作 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称是什么。是否可以从所有数组中解析数据而无需名称且不更改其结构?如何使用 Volley 解析多个 JSON 数组?

您的 JSON String 由一个 array 组成,其中包含包含对象的数组。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...
}
}
