Custom array super method not accepting the list

I have created a custom list adapter, i have two constructors, passing two different lists to super methods of constructor. One super method taking list, the other super method doesn't take the list, i am getting swiggly red line. Hovering on it doesn't explain anything, error image snapshot is attached.

List adapter code

public class ListAdapter extends ArrayAdapter<Cats> {

    //the list values in the List of type hero
    List<PlantTags> tags;
    List<Cats> categories;

    boolean childFragment;
    int categoryId;

    //activity context
    Context context;

    //the layout resource file for the list items
    int resource;

    //constructor initializing the values
    public ListAdapter(Context context, int resource, List<PlantTags> tags, boolean childFragment) {
        super(context, resource, tags);
        this.context = context;
        this.resource = resource;
        this.childFragment = childFragment;
        this.tags = tags;
    }

    //constructor initializing the values
    public ListAdapter(Context context, int resource, List<Cats> cats, boolean childFragment, int categoryId) {
        super(context, resource, cats);
        this.context = context;
        this.resource = resource;
        this.childFragment = childFragment;
        this.categories = cats;
        this.categoryId = categoryId;
    }

    //this will return the ListView Item as a View
    @NonNull
    @Override
    public View getView(final int position, @Nullable View convertView, @NonNull ViewGroup parent) {

        //we need to get the view of the xml for our list item
        //And for this we need a layoutinflater
        LayoutInflater layoutInflater = LayoutInflater.from(context);

        //getting the view
        View view = layoutInflater.inflate(resource, null, false);

        //getting the view elements of the list from the view
        ImageView imageView = view.findViewById(R.id.imageView);
        TextView textViewName = view.findViewById(R.id.category_name);

        if (!childFragment) {
            //getting the hero of the specified position
            Cats hero = categories.get(position);
            //adding values to the list item
            textViewName.setText(hero.getTitle());

        } else {
            //getting the hero of the specified position
            PlantTags tag = tags.get(position);
            //adding values to the list item
            if (tag.getCategoryId() == categoryId) {
                textViewName.setText(tag.getTitle());
            }
        }

        return view;
    }

}

** Pojo model for PlantTags **

public class PlantTags {

    @Expose
    @SerializedName("Title")
    private String Title;
    @Expose
    @SerializedName("CategoryId")
    private int CategoryId;
    @Expose
    @SerializedName("Id")
    private int Id;
    @Expose
    @SerializedName("$id")
    private String $id;

    public String getTitle() {
        return Title;
    }

    public void setTitle(String Title) {
        this.Title = Title;
    }

    public int getCategoryId() {
        return CategoryId;
    }

    public void setCategoryId(int CategoryId) {
        this.CategoryId = CategoryId;
    }

    public int getId() {
        return Id;
    }

    public void setId(int Id) {
        this.Id = Id;
    }

    public String get$id() {
        return $id;
    }

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

error enter image description here

Simple ArrayAdapter does not accept two lists as far as i know. I have opted for RecycleView adapter and replaced adapter and i can now pass as many lists as i want in the constructor of recycleview. There are many code available for that. So just suggestion an alternate solution here.

Your superclass constructor has to take either four or five parameters being:

public ListAdapter(Context context, int resource, List<PlantTags> tags, boolean childFragment)

or

public ListAdapter(Context context, int resource, List<Cats> cats, boolean childFragment, int categoryId)

You need to fill all four-five parameters or create a new constructor with less.

super(context, resource, tags)

Will never work since the constructor that you are trying to call (one with three parameters) does not exist.
