Traverse array IN JSONArray

Question

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.

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

Example of JSON:

[{"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"]}]

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

i have this 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");
}

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

I try

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

but no works because are incompatible types.

I need the array to make later a Spinner

Thank you.

Calling respJSON.getJSONArray("factoresDeVenta") doesn't work? — Ken Wolf

JSONArray Factores = respJSON.getJSONArray("factoresDeVenta") and than iterate the JSONArray to transform it String[] — Kamen Goranchev

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
 }

You can store in ArrayList<String>

ArrayList<String> arrStr = new ArrayList<String>();

JSONArray jArray = respJSON.optJSONArray("factoresDeVenta");

for (int i = 0; i < jArray.length(); i++) {
     arrStr.add(jArray.getString(i));    
}

And then you can convert arraylist to string array

String[] Factores = arrStr.toArray(new String[arrStr.size()]);

JSONArray jArray = respJSON.getJSONArray("factoresDeVenta");

It would give you the array of data stored in factoresDeVenta, which you can again traverse to get the individual elements from that array.

within elements are varying, so I want to pick automatic mode and not the "getString ()", I can?

jArray.get(n) would give you the nth element of jArray.
