ArrayAdapter：getView參數變量更改爲最終

我正在開發Android 3.1應用程序，我對Android開發非常新。ArrayAdapter：getView參數變量更改爲最終

這裏是一個自定義的數組適配器在ListView使用：

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; 
    } 
}

在public View getView(int position, View convertView, ViewGroup parent)我必須要改變最終position說法。我已經這樣做了，因爲我需要在public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)方法上使用它。

如果我將position更改爲最後是否有任何問題？有沒有其他的方式可以使用position在onCheckedChanged？
