AutoCompleteTextView - disable filtering

Question

I\'m retrieving a list of strings from a webservice and I want to list them up on a AutoCompleteTextField regardless of the built-in AutoComp

Answer 1

I solved my problem by making a custom adapter extending ArrayAdapter class and overriding its getFilter() method. By doing this the list will not be filtered based on any text placed in the TextField and all items will be displayed.

public class MyAdapter extends ArrayAdapter{
    public MyAdapter(@NonNull Context context, int resource) {
        super(context, resource);
    }

    public MyAdapter(@NonNull Context context, int resource, int textViewResourceId) {
        super(context, resource, textViewResourceId);
    }

    public MyAdapter(@NonNull Context context, int resource, @NonNull Object[] objects) {
        super(context, resource, objects);
    }

    public MyAdapter(@NonNull Context context, int resource, int textViewResourceId, @NonNull Object[] objects) {
        super(context, resource, textViewResourceId, objects);
    }

    public MyAdapter(@NonNull Context context, int resource, @NonNull List objects) {
        super(context, resource, objects);
    }

    public MyAdapter(@NonNull Context context, int resource, int textViewResourceId, @NonNull List objects) {
        super(context, resource, textViewResourceId, objects);
    }

    @NonNull
    @Override
    public Filter getFilter() {
        return new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence constraint) {
                return null;
            }

            @Override
            protected void publishResults(CharSequence constraint, FilterResults results) {

            }
        };
    }
}
