我在android中是新手，尽管在数组中解析json数组时遇到问题。

我想解析此文件，但互联网上没有此类代码可通过GSON解析此文件。我使用以下代码：
JSONObject jsonObject = (JSONObject) new JSONTokener(response).nextValue();
JSONArray jsonArray = jsonObject.getJSONArray("menu");
String jsonString = jsonArray.toString();
Type type = new TypeToken<Map<String, String>>() {
}.getType();
Map<String, String> myMap = new Gson().fromJson(jsonString, type);
for (Map.Entry<String, String> entry : myMap.entrySet()) {
key = entry.getKey();
value = entry.getValue();
// do stuff
}
responseView.setText(value);
但是，它给出了String期望找到数组的错误。请帮我
使用以下代码来解析您的完整json数据。
try {
JSONObject jsonObject = new JSONObject(jsonArray);
JSONArray jsonArray1 = jsonObject.getJSONArray("menu");
Menu menu = new Menu();
if (jsonObject.has("name")) {
menu.setName(jsonObject.getString("name"));
} else {
menu.setName("");
}
List<MenuHeaders> menuHeadersList = new ArrayList<>();
for (int i = 0; i < jsonArray1.length(); i++) {
JSONObject jsonObject1 = jsonArray1.getJSONObject(i);
MenuHeaders menuHeaders = new MenuHeaders();
//Creating list to save all prices and item names
List<ItemDetails> list = new ArrayList<>();
JSONArray subHeaderJsonArray = null;
if (jsonObject1.has("Soups")) {
menuHeaders.setTitle("Soups");
subHeaderJsonArray = jsonObject1.getJSONArray("Soups");
}
if (jsonObject1.has("Starters")) {
menuHeaders.setTitle("Starters");
subHeaderJsonArray = jsonObject1.getJSONArray("Starters");
}
if (jsonObject1.has("Main Course")) {
menuHeaders.setTitle("Main Course");
subHeaderJsonArray = jsonObject1.getJSONArray("Main Course");
}
if (jsonObject1.has("Rice")) {
menuHeaders.setTitle("Rice");
subHeaderJsonArray = jsonObject1.getJSONArray("Rice");
}
if (jsonObject1.has("Breads")) {
menuHeaders.setTitle("Breads");
subHeaderJsonArray = jsonObject1.getJSONArray("Breads");
}
if (jsonObject1.has("Accompaniments")) {
menuHeaders.setTitle("Accompaniments");
subHeaderJsonArray = jsonObject1.getJSONArray("Accompaniments");
}
//Add all other sub menu items to menu object
if (jsonObject1.has("Lentils")) {
menuHeaders.setTitle("Lentils");
subHeaderJsonArray = jsonObject1.getJSONArray("Lentils");
}
if (subHeaderJsonArray != null) {
for (int index1 = 0; index1 < subHeaderJsonArray.length(); index1++) {
JSONObject subHeaderJsonObject = subHeaderJsonArray.getJSONObject(i);
ItemDetails itemDetails = new ItemDetails();
itemDetails.setName(subHeaderJsonObject.getString("name"));
itemDetails.setPrice(subHeaderJsonObject.getInt("price"));
itemDetails.setDescription(subHeaderJsonObject.getString("description"));
itemDetails.setVeg(subHeaderJsonObject.getBoolean("veg"));
itemDetails.setSpicy(subHeaderJsonObject.getString("spicy"));
list.add(itemDetails);
}
menuHeaders.setList(list);
}
menuHeadersList.add(menuHeaders);
menu.setMenuHeaders(menuHeadersList);
}
} catch (JSONException e) {
e.printStackTrace();
}
