어댑터에서 체크 박스 수를 확인하는 방법은 무엇입니까?

Question

내 애플 리케이션의 중간에 ListView가 있고 TextView와 버튼을 보유하고있는 하단에 투명한 RelativeLayout을 추가했습니다. ListView에는 각 행에 대한 확인란이 있습니다. 내 문제는 내가 클릭 한 항목으로 목록에서 선택한 항목의 양을 TextView 채울 싶습니다. 그렇게 할 수있는 방법이 있습니까? 이 내 레이아웃입니다 :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 
    <TextView 
     android:text="@string/compare_information" 
     android:textColor="#8F8F8F" 
     android:textSize="20sp" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" 
     android:background="@android:color/transparent" 
     android:layout_marginBottom="10dp" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/informationText" /> 
    <ListView 
     android:id="@+id/lvCompare" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:divider="@null" 
     android:layout_alignParentLeft="true" 
     android:layout_marginLeft="5dp" 
     android:layout_marginRight="5dp" 
     android:layout_below="@+id/informationText"> 

    </ListView> 
    <RelativeLayout 
     android:layout_width="fill_parent" 
     android:layout_height="75dp" 
     android:layout_alignParentBottom="true" 
     android:background="#90303030" > 
     <TextView 
      android:id="@+id/checkedItems" 
      android:text="0 of 10" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:textColor="#EEEEEE" 
      android:textSize="14sp" 
      android:gravity="center_vertical|left" 
      /> 
     <Button 
      android:id="@+id/compare" 
      android:background="@drawable/filter_button_layout" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:gravity="center_vertical|right" 
      android:text="@string/compare" 
      android:textColor="#FFFFFF" 
      android:textSize="18sp" 
      /> 
    </RelativeLayout> 
</RelativeLayout>

업데이트 : 작업 알았어요. 내가 지금 IDE에서 작업하고있는 것을 추가했습니다. 생성자에서 TextView 요구 사항을 만들고 필요한 경우 TextView를 어댑터에 저장했습니다. TextView가 존재하는지 테스트하기위한 로그를 설정합니다. @SagarPilkhwal에게 감사의 말을 전합니다.

private TextView cCheckedItems; 
.... 
cCheckedItems =(TextView) view.findViewById(R.id.checkedItems); 
.... 
    viewHolder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() { 
    @Override 
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
     if(isChecked && checkBoxCounter>=2){ 
      list.get(position).setChecked(false); 
      viewHolder.checkBox.setChecked(false); 
      viewHolder.cbBackground.setBackgroundResource(R.drawable.checkbox_background); 
     }else {

      cCheckedItems.setText(checkBoxCounter); //<-- ADD THIS 
      Toast.makeText(context, "there are " + checkBoxCounter + " items selected", Toast.LENGTH_LONG).show(); 
     }}});
