遍历数组中的JSONArray [英] Traverse array IN JSONArray

问题描述

我正在做的Andr​​oid应用程序，这使得调用与Array返回一个JSON作为参数Web服务，我可以通过所有的设置，轻松地保存它们。

I'm making an app for android which makes a call to a webservice that returns a json with ARRAY as a parameter, I can go through all the settings and save them easily.

问题是，当我得到我的JSON对象中返回的数组。

The problem is when I get the array that I returned within the JSON object.

JSON的例子：

[{"codigoArticulo":"0001","nombreArticulo":"CHULETAS DE CORDERO","factorVentasDefecto":"KG","precio":21.95,"factoresDeVenta":["KG","UN"]},{"codigoArticulo":"0007","nombreArticulo":"FALDETA DE CORDERO","factorVentasDefecto":"KG","precio":11.95,"factoresDeVenta":["KG","FL"]}]

我能救codigoArticulo，nombreArticulo，factorVentasDefecto和preCIO容易，但我不知道我可以拯救factoresDeVenta。

I can save "codigoArticulo", "nombreArticulo", "factorVentasDefecto" and "precio easily, BUT i don't know how i can save "factoresDeVenta".

我有这个code：

JSONArray resparray = new JSONArray(JSONdevuelto);

        for (int i = 0; i < resparray.length(); i++) {
            JSONObject respJSON = resparray.getJSONObject(i);

            int IDArticulo = respJSON.getInt("codigoArticulo");
            String NombreArticulo =  respJSON.getString("nombreArticulo");
            String FactordeVenta =  respJSON.getString("factorVentasDefecto");
            int PrecioArticulo = respJSON.getInt("precio");
}

我怎么可以在一个阵列中节省factoresDeVenta？

How i can save in one array the variables on "factoresDeVenta"?

我尝试

String[] Factores = respJSON.getJSONArray("factoresDeVenta");

但没有工作，因为不兼容的类型。

but no works because are incompatible types.

我需要的数组后做出微调

I need the array to make later a Spinner

感谢您。

推荐答案

factoresDeVenta 里面的JSONObject一个JSONArray，所以你需要使用 getJSONArray 或 optJSONArray 并使用循环从JSONArray得到的值：

factoresDeVenta is an JSONArray inside JSONObject so you will need to use getJSONArray or optJSONArray and use loop for getting values from JSONArray:

 JSONArray jArray = respJSON.optJSONArray("factoresDeVenta");
 for (int i = 0; i < jArray.length(); i++) {
   String str_value=jArray.optString(i);  //<< jget value from jArray
 }
