Android Checkbox doesn't return right value

I'm using custom listview that has checkbox. And I want to know checkbox is checked or not. So I used getCheckedItemPositions() to get checked_info. If I set "android:clickable = "true" ", checkboxs don't return result. However if I set "android:clickable = "false" ", nothing changes in view but checkboxs return their checked information. What is problem? Bottom codes are my method that use getCheckedItemPostions() and XML code of custom listiview.

public void deleteButton(View v)
{
    int i,count;
    count = mMyAdapter.mItems.size();
    SparseBooleanArray checked = mListView.getCheckedItemPositions();
}
