for a Map (HashMap), you may use JSONObject.keys() or JSONObject.names() for retrieving all keys eg: a, b, c..., and then JSONObject.getInt(String name) get each of their mapped values. for a List of values, just try JSONObject.getInt(int index), JSONObject.length() to get values in a loop in you case. and create an ArrayAdapter for your spinner. wenbo
