这个错误使我发疯，我尝试使用诸如JsonArrayRequest和JsonObjectRequest之类的不同Volley请求，但是没有运气！
com.google.gson.JsonSyntaxException：java.lang.IllegalStateException：预期为BEGIN_ARRAY，但位于第1行第2列路径的BEGIN_OBJECT $

片段内的请求方法

requestQueue = Volley.newRequestQueue(getActivity());
StringRequest jRequest = new StringRequest(Request.Method.GET, ENDPOINT, onPostsLoaded, onPostsError);
requestQueue.add(jRequest);
}
private final Response.Listener<String> onPostsLoaded = new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Gson gson = new Gson();
Type listType = new TypeToken<List<Order>>() {}.getType();
modelData = gson.fromJson(response, listType);
adapter = new OrdersDataAdapter((ArrayList<Order>) modelData, getActivity());
recyclerView.setAdapter(adapter);
adapter.setMode(Attributes.Mode.Single);
}
};
private final Response.ErrorListener onPostsError = new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("PostActivity", error.toString());
}
};
最佳答案
在这里，您的问题是orders对象。您不反序列化orders。你可以解决这个问题
public class OrderHolder{
private List<Order> orders;
public List<Order> getOrders(){ return orders; }
}
OrderHolder holder = new Gson().fromJson(response, OrderHolder.class);
modelData = holder.getOrders();
要么
JsonElement jelement = new JsonParser().parse(response);
JsonObject jobject = jelement.getAsJsonObject();
String ordersString = jobject.get("orders").getAsString();
Gson gson = new Gson();
Type listType = new TypeToken<List<Order>>() {}.getType();
modelData = gson.fromJson(ordersString, listType);
