sorry for my bad english:

CursorAdapter class:

public class MyAdapter extends CursorAdapter {

    Context b;   
    LayoutInflater inflater;
    @SuppressWarnings("deprecation")
    public MyAdapter(Context context, Cursor c) {
        super(context, c);
        inflater = LayoutInflater.from(context);
        b= (Context) context;
    }

    @SuppressWarnings("unused")
    @Override
    public void bindView(View view, Context context, final Cursor cursor) {
        // TODO Auto-generated method stub

        TextView tv1 = (TextView)view.findViewById(R.id.txt_name);
        TextView tv2 = (TextView)view.findViewById(R.id.txt_numer);

        tv1.setText(cursor.getString(2));
        tv2.setText(cursor.getString(3));

        final int pos = cursor.getPosition();

        final CheckBox repeatChkBx = (CheckBox)view.findViewById(R.id.favorite_check);

        String me = cursor.getString(cursor.getColumnIndex("like"));

        if (me.equals("yes")) {
            repeatChkBx.setChecked(true);
        } else {
            repeatChkBx.setChecked(false);
        }

        repeatChkBx.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View view) {
                MyDatabase MyDatabase = new MyDatabase(b);
                SQLiteDatabase mydb = MyDatabase.getWritableDatabase();
                cursor.moveToPosition(pos);

                if (repeatChkBx.isChecked()) {                   
                    mydb.execSQL("update list set like = 'yes' where id = " + cursor.getString(1));

                }else{
                    mydb.execSQL("update list set like = 'no' where id = " + cursor.getString(1));           

                }
            }
        });

        }

        protected Context getActivity() {
            // TODO Auto-generated method stub
            return null;
        }

        @Override
        public View newView(Context context, Cursor cursor, ViewGroup parent) {
            return inflater.inflate(R.layout.item, parent, false);
        }
    }

problem is when you update your database just database going to update not cursor that adapt your cursor adapter ,so you have to use

 changeCursor(newcursor);

in your adapter after updating your database. hope this help you.
