ArrayAdapter: getView argument variable changed to final

I'm developing an Android 3.1 application and I'm very very new on Android development.

Here is a custom array adapter to use in a ListView:

public class FormAdapter extends ArrayAdapter<Form>
 {
     private Context context;
     private int layoutResourceId;
     private List<Form> forms;
     public ArrayList<String> checkedItems;
     private Button downloadButton;
 
     public ArrayList<String> getCheckedItems()
     {
         return checkedItems;
     }
 
     public FormAdapter(Context context, int textViewResourceId,
             List<Form> objects, Button downloadButton)
     {
         super(context, textViewResourceId, objects);
 
         this.context = context;
         this.layoutResourceId = textViewResourceId;
         this.forms = objects;
         this.checkedItems = new ArrayList<String>();
         this.downloadButton = downloadButton;
     }
 
     @Override
     public View getView(final int position, View convertView, ViewGroup parent)
     {
         View row = convertView;
         if (row == null)
         {
             LayoutInflater inflater = ((Activity)context).getLayoutInflater();
             row = inflater.inflate(layoutResourceId, parent, false);
         }
 
         Form f = forms.get(position);
         if (f != null)
         {
             CheckBox checkBox = (CheckBox)row.findViewById(R.id.itemCheckBox);
             if (checkBox != null)
             {
                 checkBox.setText(f.Name);
                 checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener()
                 {
                     public void onCheckedChanged(CompoundButton buttonView,
                             boolean isChecked)
                     {
                         Form f = forms.get(position);
                         if (isChecked)
                         {
                             checkedItems.add(f.FormId);
                         }
                         else
                         {
                             checkedItems.remove(checkedItems.indexOf(f.FormId));
                         }
                         downloadButton.setEnabled(checkedItems.size() > 0);
                     }
                 });
             }
         }
 
         return row;
     }
 }
 

On public View getView(int position, View convertView, ViewGroup parent) I have to change to final position argument. I have done it because I need to use it on public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) method.

Is there any problem if I change position to final?
Is there any other way to use position on onCheckedChanged?
