ArrayAdapter requires the resource ID to be a TextView in Custom Adapter

I build custom arrayAdapter to show a progress bar into spinner, my xml for row be like this 

<ProgressBar
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/progressBar"
 style="?android:attr/progressBarStyle"
 android:layout_width="match_parent"
 android:layout_height="wrap_content" />

and my custom adapter 

public class CustomAdapter extends ArrayAdapter 
{

    private Context mContext;

    public CustomAdapter(@NonNull Context context, int resource,int textViewResourceId) {
        super(context, resource,textViewResourceId);
        mContext = context;
    }

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        LayoutInflater inflater = LayoutInflater.from(mContext);
        View row = inflater.inflate(R.layout.default_spinner_progress,parent,false);
        return row;
    }

    @Override
    public int getCount() {
        return 1;
    }
}

I initialize it 

transferSpinner.setAdapter(new CustomAdapter(getContext(),R.layout.default_spinner_progress,R.id.progressBar));

I got this error in stack trace 

E/AndroidRuntime: FATAL EXCEPTION: main
   Process: com..debug, PID: 9537
   java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView

use a BaseAdapter instead 

public class CustomAdapter extends BaseAdapter {

    private Context mContext;

    public CustomAdapter(@NonNull Context context) {
        this.mContext = context;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = convertView;
        if (view == null) {
            LayoutInflater inflater = LayoutInflater.from(mContext);
            view = inflater.inflate(R.layout.default_spinner_progress, parent, false);
        }
        return view;
    }

    @Override
    public int getCount() {
        return 1;
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }
}

call it using: transferSpinner.setAdapter(new CustomAdapter(this));
