Custom TypeAdapter(Retrofit2.x)

[Manu-Bhardwaj]

Is there any way to add multiple custom type adapters to a single client builder using addConverterFactory

Not much information to go off of, but if you are asking about registering multiple TypeAdapters in Gson and then using it in Retrofit you could do the following:

Gson gson = new GsonBuilder()
            .registerTypeAdapter(Type1.class, new Type1Adapter())
            .registerTypeAdapter(Type2.class, new Type2Adapter())
            .build();
Api api =  new Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create(gson))
            .baseUrl(url)
            .build()
            .create(Api.class);

I am parsing a json response whose structure is as follows: ->query(object)

results(object) scorecard(can be a list of objects or a single object) pastIngs(can be list or object)

Here are the POJO classes and custom type adapters.Plz check if anything is wrong

`public class Results {

private List<com.test.cric.live_model.all_matches_summary.Scorecard> Scorecard= new ArrayList<com.test.cric.live_model.all_matches_summary.Scorecard>();
/**
 *
 * @return
 *     The Scorecard
 */
public List<com.test.cric.live_model.all_matches_summary.Scorecard> getScorecard() {
    return Scorecard;
}

/**
 *
 * @param Scorecard
 *     The Scorecard
 */
public void setScorecard(List<com.test.cric.live_model.all_matches_summary.Scorecard> Scorecard) {
    this.Scorecard = Scorecard;
}

} public class Scorecard {

public void set_past_ing(Past_ing ... p) {
    past_ings = Arrays.asList(p);
}
public void set_teams(Team ... t) {
    teams = Arrays.asList(t);
}

private String mid;
private Series series;
private String mn;
private List<Team> teams = new ArrayList<Team>();
private List<Past_ing> past_ings = new ArrayList<Past_ing>();
private Result result;

//Getters and setters

}`

`public class ResultsTypeAdapter extends TypeAdapter {

private Gson gson = new Gson();

@Override
public void write(JsonWriter jsonWriter, Results results) throws IOException {
    gson.toJson(results, Results.class, jsonWriter);
}

@Override
public Results read(JsonReader jsonReader) throws IOException {
    Results results=new Results();

    jsonReader.beginObject();
    jsonReader.nextName();

    if (jsonReader.peek() == JsonToken.BEGIN_ARRAY) {
        results = new Results((Scorecard[]) gson.fromJson(jsonReader, Scorecard[].class));
    } else if(jsonReader.peek() == JsonToken.BEGIN_OBJECT) {
        results = new Results((Scorecard) gson.fromJson(jsonReader, Scorecard.class));
    } else {
        throw new JsonParseException("Unexpected token " + jsonReader.peek());
    }

    jsonReader.endObject();
    return results;
}
