Android DBFLOW With Retrofit

Question

I'm using DBFlow to save into the database and Retrofit to call my web service. My retrofit class is the same class as my database table. Here what I did so far, but I want to know how to save data and get data using this, please send me any ideas about this

Here is my model:

@Table(database = SimplifyaDatabase.class, name = "Question")
public class Question extends BaseModel {


@Column
@PrimaryKey
@SerializedName("question_id")
@Expose
private int questionId;

@Column
@SerializedName("question")
@Expose
private String question;

@Column
@SerializedName("question_answer_id")
@Expose
private String questionAnswerId;

@Column
@SerializedName("explanation")
@Expose
private String explanation;

@Column
@SerializedName("category_id")
@Expose
private String categoryId;


@SerializedName("citations")
@Expose
private List<Citation> citations = null;
@SerializedName("answers")
@Expose
private List<Answer> answers = null;


public int getQuestionId() {
    return questionId;
}

public void setQuestionId(int questionId) {
    this.questionId = questionId;
}

public String getQuestion() {
    return question;
}

public void setQuestion(String question) {
    this.question = question;
}

public String getQuestionAnswerId() {
    return questionAnswerId;
}

public void setQuestionAnswerId(String questionAnswerId) {
    this.questionAnswerId = questionAnswerId;
}

public String getExplanation() {
    return explanation;
}

public void setExplanation(String explanation) {
    this.explanation = explanation;
}

public String getCategoryId() {
    return categoryId;
}

public void setCategoryId(String categoryId) {
    this.categoryId = categoryId;
}

public List<Citation> getCitations() {
    return citations;
}

public void setCitations(List<Citation> citations) {
    this.citations = citations;
}

public List<Answer> getAnswers() {
    return answers;
}

public void setAnswers(List<Answer> answers) {
    This. answers = answers;
}
}

And this is my retrofit call

this.questionListSubscription = this.makeUIObservable(questionService.getAllQuestions(appointmentId, 1))
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(
                    questions -> {
                        //save data


                        this.hideProgress();

                    },
                    error -> this.hideProgress()
            );

Now I want to save data and get data from database after save, I am stuck with here, Please help me
