Its too late but may help some one.

set your listview choice mode to single choice and declare global integer variable with value -1.

int cPos=-1;

listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

    listView.setOnItemClickListener(new OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> parent, View view,
                        int position, long id) {
                    // TODO Auto-generated method stub

                    if (cPos == position) {
                        if(listView.isItemChecked(cPos)){
                            listView.setItemChecked(position, false);   
                        }else{
                            listView.setItemChecked(position, true);
                        }
                    } else {
                        listView.setItemChecked(position, true);
                    }
                    cPos = listView.getCheckedItemPosition();

                }
            });
