我试过
{
final JSONObject output = response.getJSONObject("data");
if (output.getString("success").equalsIgnoreCase("true")) {
final JSONArray orderDetails = output.getJSONArray("orders");
for (int i = 0; i < orderDetails.length(); i++) {
// Get single order object
JSONObject orderData = orderDetails.getJSONObject(i);
// Get product details object
JSONArray products = orderData.getJSONArray("productDetails");
for (int k = 0; k < products.length(); k++) {
JSONObject productData = products.getJSONObject(k);
JSONObject optionData = productData.getJSONObject("optionDetails");
ProductDetailsModel product = new ProductDetailsModel(
productData.getString("productId"),
productData.getString("storeId"),
productData.getString("productName"),
productData.getString("quantity"),
productData.getString("productAmount"),
productData.getString("totalAmount"),
optionData.getString("optionId"),
optionData.getString("optionName"),
optionData.getString("optionAmount")
);
productsList.add(product);
//System.out.println(productsList);
for (int j =0; j< productsList.size(); j++){
System.out.println("Hey data: "+productsList.get(j).getQuantity());
}
}
// Get user address object
JSONObject userAddress = orderData.getJSONObject("userAddressDetails");
UserAddressDetailsModel addressModel = new UserAddressDetailsModel(
userAddress.getString("firstName"), userAddress.getString("middleName"),
userAddress.getString("lastName"), userAddress.getString("email"),
userAddress.getString("mobileNo"), userAddress.getString("address"),
userAddress.getString("landMark"), userAddress.getString("city"),
userAddress.getString("zipCode"), userAddress.getString("stateName"),
userAddress.getString("countryName"), userAddress.getString("latitude"),
userAddress.getString("longitude"));
ordersList.add(addressModel);
Order order = new Order(orderData.getString("tax"),
orderData.getString("shippingCharges"),
orderData.getString("amount"),
orderData.getString("subTotal"),
orderData.getString("discount"),
orderData.getString("prefix"),
orderData.getString("createdOn"),
orderData.getString("couponCode"),
orderData.getString("orderId"),
orderData.getString("deliveryCode"),
orderData.getString("shopId"),
orderData.getString("createdBy"),
orderData.getString("status"),
productsList, addressModel);
orders.add(order);
}
adapter.notifyDataSetChanged();
} else{
Toast.makeText(getActivity(), output.getString("message"), Toast.LENGTH_LONG).show();
}
}
它导致子（ productDetails ）嵌套父（订单）json数组的json数组中的重复条目。

试试这个
try {
JSONObject jsonObject= new JSONObject(readJSONFromAsset());
JSONObject mainJsonObject = jsonObject.getJSONObject("data");
String success = mainJsonObject.getString("success");

String shippingCharges=orderJsonObject.getString("shippingCharges");
String deliveryCode=orderJsonObject.getString("deliveryCode");
String shopId=orderJsonObject.getString("shopId");
String amount=orderJsonObject.getString("amount");
String subTotal=orderJsonObject.getString("subTotal");
String discount=orderJsonObject.getString("discount");

修改
您可以使用Gson来解析JSON
Gson是一个Java库，可用于将Java对象转换为JSON表示形式。它还可用于将JSON字符串转换为等效的Java对象。Gson可以处理任意Java对象，包括您没有源代码的预先存在的对象。
使用http://www.jsonschema2pojo.org/

使用
Gson解析，如下面的代码
String apiResponse = readJSONFromAsset();
Gson gson = new GsonBuilder().create();
Example resultObj = gson.fromJson(apiResponse, Example.class);
ArrayList<Order> orders = new ArrayList<>();
orders.addAll(resultObj.getData().getOrders());
Log.e("_SIZE", orders.size()+"_SIZE");
for (int i = 0; i < orders.size(); i++) {
Log.e("resultOb", orders.get(i).getAmount()+"amount");
Log.e("resultOb", orders.get(i).getCouponCode()+"getCouponCode");
Log.e("resultOb", orders.get(i).getDeliveryCode()+"getDeliveryCode");
for (int j=0;j<orders.get(i).getProductDetails().size();j++){
Log.e("resultOb", orders.get(i).getProductDetails().get(j).getTotalAmount() + "");
Log.e("resultOb", orders.get(i).getProductDetails().get(j).getProductId() + "");
Log.e("resultOb", orders.get(i).getProductDetails().get(j).getProductName() + "");
Log.e("resultOb", orders.get(i).getProductDetails().get(j).getQuantity() + "");
}
