У меня есть представление списка, заполненное из файла JSON (поскольку мое приложение будет отключено) с использованием пользовательского адаптера представления списка. Представление списка фильтруется в соответствии с категорией, когда я запускаю свое приложение, лог-кот не дает мне ошибок, но представление списка заполняется только элементом каждой категории. Вот пример моего кода и файла JSON. Код немного беспорядочный, и это гигантский цикл.
Intent intent = CategoryItemsActivity.this.getIntent();
String category = (String) intent.getExtras().get("categoryName");
int destinationId = intent.getExtras().getInt("destinationID");
String feed = loadJSONFromAsset();
try {
JSONObject mJsonObj = new JSONObject(feed);
JSONArray jsonArray = mJsonObj.getJSONArray("partners");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String name = jsonObject.getString("name");
String categoryname = jsonObject.getString("category_name");
Double lat = jsonObject.getDouble("lat");
Double lng = jsonObject.getDouble("lang");
String address = jsonObject.getString("address");
int destid = jsonObject.getInt("destination_id");
String thumbnail_image = jsonObject
.getString("thumbnail_image");
compare.put(name, destid);
hashmapNames.put(categoryname, name);
hashmapAddress.put(name, address);
thumbnailimages.put(name, thumbnail_image);
latitudes.put(name, lat);
longitudes.put(name, lng);
}
} catch (Exception e) {
e.printStackTrace();
}
for (Entry<String, Integer> entry1 : compare.entrySet()) {
String key1 = entry1.getKey();
