How to display jsonObject parsed from jsonArray to TextView?

Hi, I have a data model Currency with 3 fields and getter/setters. How can I display a single jsonObject for example a "name" that I get from jsonArray to a textView in displayData() method?

private void displayData() {

    how to set "name" jsonObject to nName textview?

}


private Currency[] parsingJson(String data) throws JSONException {
    JSONArray jsonArray = new JSONArray(data);

    Currency[] currencies = new Currency[data.length()];

    for (int i = 0; i < jsonArray.length(); i++) {
        JSONObject jsonCurrency = jsonArray.getJSONObject(i);
        Currency currency = new Currency();

        currency.setmName(jsonCurrency.getString("name"));
        currency.setmSymbol(jsonCurrency.getString("symbol"));
        currency.setmPriceUsd(jsonCurrency.getDouble("price_usd"));

        Log.d("TAG", currency.getmName() +" " + currency.getmSymbol() + " " + currency.getmPriceUsd());

        currencies[i] = currency;

    }

    return currencies;
}
