Save checkbox state from a listview in an ArrayList

I have been using a ListView with each item a CheckableLinearLayout as defined in

CheckableLinearLayout

I cannot check any row in the ListView, it does not even register the check in the UI. I do not believe there is a android:checkMark for the CheckableLinearLayout. Is it correct to nest the CheckedTextView inside my CheckableLinearLayout, would it be better if I used a CheckBox instead. Also, how can I put them in the ArrayList as soon as they are checked, instead of iterating over them in this manner.

This is my layout:

   <com.example.deltest.CheckableLinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 >
<CheckedTextView 
android:id="@android:id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:checkMark="?android:attr/listChoiceIndicatorMultiple"
 />
<TextView android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:id="@+id/txt_a"
          />
<TextView android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:id="@+id/txt_b"
    />

   </com.example.deltest.CheckableLinearLayout>

I have implemented the listActivity as follows:

    public class DeleteList extends ListActivity 
    {
    ArrayList<Integer> idList=new ArrayList<Integer>();
    Cursor  c;
    Handler handler;
    static final int WHAT=0;
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
    super.onCreate(savedInstanceState);
    final TumblrDB db=new TumblrDB(this);
    c=db.query();
    startManagingCursor(c);
    handler=new Handler();
    View v=getLayoutInflater().inflate(R.layout.layout_header, null,false);
    getListView().addHeaderView(v);
    getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    SimpleCursorAdapter adapter=new SimpleCursorAdapter(this,R.layout.layout_del,c,new String[] {TumblrDB.DATE,TumblrDB.DESC},new int[]{R.id.txt_a,R.id.txt_b});
    getListView().setAdapter(adapter);
    if(handler.hasMessages(WHAT))
    {
        c=db.query();
        ((SimpleCursorAdapter)getListView().getAdapter()).swapCursor(c);
    }

    Button btn_del=(Button)v.findViewById(R.id.btn_del);
    btn_del.setOnClickListener(new OnClickListener(){

        @Override
        public void onClick(View view) {
            // TODO Auto-generated method stub
            int count=getListView().getCount();
            SparseBooleanArray sparseBooleanArray=getListView().getCheckedItemPositions();
            for(int i=0;i<count;i++)
            {
                if(sparseBooleanArray.get(i))
                {
                    c.moveToPosition(i);
                    int _id=c.getInt(c.getColumnIndex(TumblrDB._ID));
                    Log.d("DeleteList", "The id has been added "+_id);
                    idList.add(_id);
                    new Thread()
                    {
                        public void run()
                        {
                            for(int i:idList)
                            {
                                db.delete(i);
                                Log.d("DeleteList", "The id has been deleted "+i);
                                handler.sendEmptyMessage(WHAT);
                            }
                        }
                    }.start();
                }
            }
        }

    });

}   

 }

EDIT Trying a different approach to solve the problem by extending SimpleCursorAdapter:

    if(row==null)
    {
        row=inflater.inflate(layout, null, false);
        holder=new ViewHolder(row,position);
        row.setTag(holder);
        holder.check_del.setTag(position);
    }
    else
    {
        holder=(ViewHolder)row.getTag();
        holder.check_del.setOnClickListener(null);
        holder.check_del.setTag(position);
        if(hitList.get(position))
            holder.check_del.setChecked(true);
        else
            holder.check_del.setChecked(false);
    }

Then I have implemented an OnClickListener for the CheckBox:

      OnClickListener cbl=new OnClickListener(){

        @Override
        public void onClick(View view) {
            // TODO Auto-generated method stub
            int position=(Integer)view.getTag();
            Log.d("CustomCursorAdapter", "The checkbox at postion "+position+" has been clicked");
            if(((CheckBox)view).isChecked())
            {
                hitList.set(position, true);
            }
            else 
            {
                hitList.set(position, false);
            }
        }
    };  

Now when I try to access the ArrayList that I am using,it throws an ArrayOutOfBoundsException:

    btn_del.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View view) {
            // TODO Auto-generated method stub
            new Thread()
            {
                public void run()
                {
                    int count=lv.getCount();
                    for(int i=0;i<count;i++)
                    {
                        if(adapter.hitList.get(i))
                        {
                            db.delete(c.getInt(c.getColumnIndex(TumblrDB._ID)));
                        }
                    }
                }
            }.start();
            adapter.notifyDataSetChanged();
        }
    });
