How to get json array values in android?

Question

JSON response value looks like this "types" : [ "sublocality", "political" ]. How to get the first value of the types or how to get the word sublocality?

Answer 1

String string = yourjson;

JSONObject o = new JSONObject(yourjson);
JSONArray a = o.getJSONArray("types");
for (int i = 0; i < a.length(); i++) {
    Log.d("Type", a.getString(i));
}

This would be correct if you were parsing only the line you provided above. Note that to access types from GoogleMaps geocode you should get an array of results, than address_components, then you can access object components.getJSONObject(index).

This is a simple implementation that parses only formatted_address - what I needed in my project.

private void parseJson(List<Address> address, int maxResults, byte[] data)
{
    try {
        String json = new String(data, "UTF-8");
        JSONObject o = new JSONObject(json);
        String status = o.getString("status");
        if (status.equals(STATUS_OK)) {

            JSONArray a = o.getJSONArray("results");

            for (int i = 0; i < maxResults && i < a.length(); i++) {
                Address current = new Address(Locale.getDefault());
                JSONObject item = a.getJSONObject(i);

                current.setFeatureName(item.getString("formatted_address"));
                JSONObject location = item.getJSONObject("geometry")
                        .getJSONObject("location");
                current.setLatitude(location.getDouble("lat"));
                current.setLongitude(location.getDouble("lng"));

                address.add(current);
            }

        }
    catch (Throwable e) {
        e.printStackTrace();
    }

}
