Google Places API的GSON解析

Question

I need a little help with creating classes which will be filled with GSON parser. This is the output od autocomplete Google Places API:

{
   "predictions" : [
  {
     "reference" : "CjQtAA",
     "terms" : [
        {
           "offset" : 0,
           "value" : "Ladimirevci"
        },
        {
           "offset" : 13,
           "value" : "Hrvatska"
        }
     ],
     "types" : [ "locality", "political", "geocode" ]
  },
  {
     "reference" : "CjQtAAA",
     "terms" : [
        {
           "offset" : 0,
           "value" : "Ladimirevci"
        },
        {
           "offset" : 13,
           "value" : "Hrvatska"
        }
     ],
     "types" : [ "locality", "political", "geocode" ]
  }
],
  "status" : "OK"
}

SOLUTION thanks to MikO

Classes are:

public class GPlacesAPIResults {

    @SerializedName("predictions")
    public List<GPlacesAPILocation> predictions;

    @SerializedName("status")
    public String status;

}

Second:

public class GPlacesAPILocation implements Serializable {

    private static final long serialVersionUID = 4509808527882750586L;

    @SerializedName("reference")
    private String reference;

    @SerializedName("terms")
    private List<GPlacesAPIAddress> terms;

    @SerializedName("types")
    private List<String> types;

    }

Third:

public class GPlacesAPIAddress implements Serializable {

    private static final long serialVersionUID = -6916297127791361853L;

    @SerializedName("value")
    public String value;

    }

In app I call it like this

InputStreamReader in = new InputStreamReader(conn.getInputStream()); //results from places api

GPlacesAPIResults lcs = new Gson().fromJson( in , GPlacesAPIResults.class);

Thank you for the effort :-)

Answer 1

Your Result class with an attribute locations doesn't make any sense... in fact I don't understand why you came up with that, since there's no locations element anywhere in your JSON!

Try something like this (following your particular notation ):

Results
List<Locations> predictions;
String status;

Locations
String reference;
List <Addresses> terms;

Addresses
String value;
