I am working on a quiz app basically. In my app there are many questions getting datas from Firebase Database with those areas (question, optionA,optionB,optionC,optionD and correctANS) but I want to improve my project. I want to add image questions instead of text questions. For this I added an area(urlImage) to my database on Firebase. Normally I can get data from Firebase except urlImage but I didn't see Image in ImageView in my app. What should i do? Please someone help me?

those are my QuestionsActivity codes:

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_questions);
        Toolbar toolbar=findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        question=findViewById(R.id.question);
        urlImage=findViewById(R.id.urlImage);
        noIndicator=findViewById(R.id.no_indicator);
        bookmarkBtn=findViewById(R.id.bookmark_btn);
        optionsContainer=findViewById(R.id.option_container);
        shareBtn=findViewById(R.id.share_btn);
        nextBtn=findViewById(R.id.next_btn);

        preferences=getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);
        editor=preferences.edit();
        gson=new Gson();

        getBookmarks();
        bookmarkBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (modelMatch()){
                    bookmarkslist.remove(matchedQuestionPosition);
                    bookmarkBtn.setImageDrawable(getDrawable(R.drawable.bookmark_border));
                }else{
                    bookmarkslist.add(list.get(position));
                    bookmarkBtn.setImageDrawable(getDrawable(R.drawable.bookmark));
                }
            }
        });


        setId=getIntent().getStringExtra("setId");

        loadingDialog=new Dialog(this);
        loadingDialog.setContentView(R.layout.loading);
        loadingDialog.getWindow().setBackgroundDrawable(getDrawable(R.drawable.rounded_corner2));
        loadingDialog.getWindow().setLayout(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);
        loadingDialog.setCancelable(false);

        list=new ArrayList<>();
        loadingDialog.show();
        myRef.child("SETS").child(setId).addListenerForSingleValueEvent(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                for (DataSnapshot dataSnapshot1 :dataSnapshot.getChildren()){
                    String id=dataSnapshot1.getKey();
                    String question= dataSnapshot1.child("question").getValue().toString();
                    String a= dataSnapshot1.child("optionA").getValue().toString();
                    String b= dataSnapshot1.child("optionB").getValue().toString();
                    String c= dataSnapshot1.child("optionC").getValue().toString();
                    String d= dataSnapshot1.child("optionD").getValue().toString();
                    String correctANS= dataSnapshot1.child("correctANS").getValue().toString();
                    String urlImage= dataSnapshot1.child("urlImage").getValue().toString();

                    list.add(new QuestionModel(id,question,a,b,c,d,correctANS,urlImage,setId));

those are my QuestionModel codes:

public class QuestionModel {

        this.id = id;
        this.question = question;
        A = a;
        B = b;
        C = c;
        D = d;
        this.answer = answer;
        this.set = set;
        this.urlImage=urlImage;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getQuestion() {
        return question;
    }

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

    public String getA() {
        return A;
    }

    public void setA(String a) {
        A = a;
    }

    public String getB() {
        return B;
    }

    public void setB(String b) {
        B = b;
    }

    public String getC() {
        return C;
    }

    public void setC(String c) {
        C = c;
    }

    public String getD() {
        return D;
    }

    public void setD(String d) {
        D = d;
    }

    public String getAnswer() {
        return answer;
    }

    public void setAnswer(String answer) {
        this.answer = answer;
    }

    public String getSet() {
        return set;
    }

    public void setSet(String set) {
        this.set = set;
    }

    public String getUrlImage() {

    }

    public void setUrlImage(String urlResim) {

    }
