In my Activity i have a EditText, ImageView and Button.I place a ImageView inside the GridView, When My Activity was loaded.

The Gridview First Image was Selected Default and i want to Enter the EditText name and pass both the EditText value and the Default selected image( user can also Choose his Own Image if he dont like the default image ) to the New Activity

My Problem is User Enter the edittext value and he press the Button it pass only the EditText value not the default Selected Image, If user Choose the other Images in the gridview it pass both the ImageView and the EditText value also if he Choose the default selected image manually then it works Fine .

    int imageRes;

    public NewListCreate() {
    }
         public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        
                 View view = inflater.inflate(R.layout.new_list_create, container, false);
        
                ImageButton done = view.findViewById(R.id.done);
                final EditText listname = (EditText) view.findViewById(R.id.listname);
                final GridView gridView = (GridView) view.findViewById(R.id.gridview);
        
                final CustomAdpter customAdpter = new CustomAdpter(images,getContext());
                gridView.setAdapter(customAdpter);
                gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                    @Override
                    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                        customAdpter.selectedImage = i;
                        customAdpter.notifyDataSetChanged();
                        imageRes = images[i];
       
                    }
                });
     done.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
    
    
                    String itemname = listname.getText().toString();
                    if (!TextUtils.isEmpty(listname.getText().toString())) {
    
                        startActivity(new Intent(getContext(), CheckslateHome.class).putExtra("data", itemname).putExtra("image",imageRes));
                        dismiss();
                    } else {
                        Toast.makeText(getContext(), "List Name not Empty ", Toast.LENGTH_SHORT).show();
                    }
    
                }
