Iterate through JSONObject in java (android)

Assuming your JSON is in a string form, you can iterate over the attribute-value pairs as follows:

Below String jsonstring is the string of json.

String jsonstring = "{ "child": { "something": "value", "something2": "value" } }";
JSONObject resobj = new JSONObject(jsonstring);
Iterator<?> keys = resobj.keys();
while(keys.hasNext() ) {
    String key = (String)keys.next();
    if ( resobj.get(key) instanceof JSONObject ) {
        JSONObject xx = new JSONObject(resobj.get(key).toString());
        Log.d("res1",xx.getString("something"));
        Log.d("res2",xx.getString("something2"));
    }
}
