How to parse Json Array using gson in android

Question

I am developing an Android application and I am using gson to parse the json response. My json answer looks like

[{"customerid":"abc","customername":"abc","location":null} ,{"customerid":"xyz","customername":"xyz","location":null}] 

And the class to parse this answer is as follows:

 public class CustomerInfo { @SerializedName("customerid") public String customerid; @SerializedName("customername") public String customername; @SerializedName("location") public String location; public CustomerInfo() {} } 

I tried this as follows:

  Gson gson = new Gson(); List<CustomerInfo> customers = (List<CustomerInfo>)gson.fromJson(result,CustomerInfo.class); 

But it does not work for me. How to do it. Need help. Thanks.

Answer 1

First you create getters and setters for all your variables inside the CustomerInfo class ie for customerid, customername and location, then you can parse JSON using the code snippet below:

 Gson gson = new Gson(); JsonData gsonData = gson.fromJson(response, CustomerInfo.class); for (int j = 0; j < gsonData.getCount(); j++) { String customerid = gsonData.get(j).getCustomerId(); String customername = gsonData.get(j).getCustomerName(); String location = gsonData.get(j).getLocation(); }
