Подгружаю данные с сервера.
public class ServerTask extends AsyncTask<Void,Void,ArrayList<Map<String, String>>> {
protected void onPreExecute(){}
@Override
protected ArrayList<Map<String, String>> doInBackground(Void... voids) {
return ServerRequest.getRecipesList();
}
@Override
protected void onPostExecute(ArrayList<Map<String, String>> list) {
super.onPostExecute(list);
}
}
Ещё у меня есть свой адаптер.
RecipeListAdapter(Context context, ArrayList<Map<String, String>> list) {
//...code...
}
Приложение создано по шаблону с выезжающим меню (NavigationDrawerFragment).
В "R.layout.fragment_main" есть ListView для которого нужно создать и передать Adapter, не могу сообразить как это сделать. Вот весь код Activity, на всякий случай.
Помогите пожалуйста =(
