如何从适配器获取选中的复选框计数？

我在应用程序的中间有一个ListView，并且在底部添加了一个透明的RelativeLayout，其中包含一个TextView和一个按钮。在ListView中，每一行都有一个复选框。我的问题是，当单击一个项目时，我想用列表中选中项目的数量填充TextView。有没有办法做到这一点？这是我的布局：

<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>

这是我的适配器：

    public class CompareListAdapter extends ArrayAdapter<Restaurant>{
        private ArrayList<Restaurant> list = new ArrayList<Restaurant>();
        private Context context;
        private static int checkBoxCounter = 0;
        private static int checkBoxInitialized = 0;
        private int layoutResourceId;
        private TextView cCheckedItems;
        private final String INFORMATION_TEXT = "Select six companies to compare";

        public CompareListAdapter(Context context, int resource,
                List<Restaurant> objects,TextView textViewToEdit ) {
            super(context, resource, objects);
            this.context = context;
            this.layoutResourceId = resource;
            checkBoxCounter = 0;
            cCheckedItems = textViewToEdit;
            // We put the strings from the array in to the hash map for storing
            for (int i = 0; i < objects.size(); ++i) {
                list.add(objects.get(i));
            }
        }

        public View getView( final int position, View convertView, ViewGroup parent) {
            View view = null;
            if(convertView==null){

                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 {

                            element.setChecked(buttonView.isChecked());

        }
    }

更新：可以正常工作了。添加了我现在在IDE上进行的工作。我在构造函数中提出了TextView要求，并将该TextView保存在适配器中，然后在需要时调用它。设置日志以测试TextView是否存在。感谢@SagarPilkhwal指导解决方案。
