How to extract the value of "text" by using GSON/Retrofit?

    {
       code: 200,
       lang: "en-ms",
       text: [
           "Burung"
       ]
    }

1 Create your model class

public class ResponseItem {

/**
 * code : 200
 * lang : en-ms
 * text : ["Burung"]
 */

private int code;
private String lang;
private List<String> text;

public int getCode() {
    return code;
}

public void setCode(int code) {
    this.code = code;
}

public String getLang() {
    return lang;
}

public void setLang(String lang) {
    this.lang = lang;
}

public List<String> getText() {
    return text;
}

public void setText(List<String> text) {
    this.text = text;
}

}

2 inside your Retrofit method response :

 if (response.isSuccessful()) {
  ResponseItem responseItem;
  responseItem = response.body(); }

and you can call text by saying responseitem.Get("whatever u want from the model class")

回答2:

text there like Map. You need to create pojo with

@SerializedName("code")
    @Expose
    private int mCode;

@SerializedName("lang")
    @Expose
    private String mLang;

@SerializedName("text")
    @Expose
    private Map <String, List<String> mText;

Create Retrofit with factory (GsonFactory). And instantiate this pojo.

p.s: also you can make serializator and deserializator for your objects

回答3:

make POJO class of given response and register this in retrofit callback and get values with the help of getters and setters.

回答4:

you can get all of object in a json and put to a array with this code:

JSONArray texts = new JSONObject(json).getJSONArray("text");
