У меня есть данные JSON, поступающие корректно с моего сервера, я просто хочу поместить его в следующий массив, но я не уверен, что данные JSON правильно вставляются в ArrayList.Ввод данных JSON в список
Вот массив
private List<ShopInfo> createList(int size) {
List<ShopInfo> result = new ArrayList<ShopInfo>();
for (int i = 1; i <= size; i++) {
ShopInfo ci = new ShopInfo();
ci.name = TAG_NAME+i;
ci.address = TAG_ADDRESS+i;
result.add(ci);
}
return result;
}
Мой JSON
{"success":1,"shops":[{"name":"Test_Shop","address":"1 Big Road Dublin"}
Файл
public class OrderCoffee extends Activity {
JSONParser jParser = new JSONParser();
ArrayList<HashMap<String, String>> shopList;
private static String url_all_products = "xxxxxxxxxx/ordercoffee.php";
// products JSONArray

// JSON Node names
private static final String TAG_SUCCESS = "success";

llm.setOrientation(LinearLayoutManager.VERTICAL);
recList.setLayoutManager(llm);
shopList = new ArrayList<HashMap<String, String>>();
ShopAdapter ca = new ShopAdapter(createList(3));
recList.setAdapter(ca);
}
class LoadAllProducts extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
// getting JSON string from URL
JSONObject json = jParser.makeHttpRequest(url_all_products, "GET", params);
// Check your log cat for JSON reponse
Log.d("All Products: ", json.toString());
try {
// Checking for SUCCESS TAG
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// products found
// Getting Array
shops = json.getJSONArray(TAG_SHOPS);

Что вы имеете в виду * "это, кажется, не входите в массив правильно для меня »*? – Rami
Я не уверен, что способ ввода данных JSON в список result = new ArrayList (); правильно, я не был уверен, как сформулировать вопрос, перефразировать. –

вы можете добавить этот метод к вашей асинхронной загрузке LoadAllProducts и напечатать свой массив: protected void onPostExecute (результат строки) {Log.d ("shopList", shopList.toString());} –
