android how to dynamically bind checkboxes with custom listview

I create checkboxes dynamically & i want to bind that checkboxes to listview.

How can I do that?

Here i give my code--


public class HomeActivity extends ListActivity{
    CheckBox[] chk;
    ListView lv1;
public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        lv1=(ListView)findViewById(R.id.listTasks);
        tv1=(TextView) findViewById(R.id.tvMsg);

The database section:

         db = new DBAdapter(HomeActivity.this);
            db.open();//int[] id=new int[]{Integer.parseInt(DBAdapter.ID)};
    Cursor cr=db.getUncompletedTask();//my database function to retrieve values to create checkboxes
            if (cr.moveToFirst()) {
                do {
                    String[] str=new String[2];
                    str[0]=cr.getString(0);
                    str[1]=cr.getString(1);
                    al.add(str);
                } while (cr.moveToNext());
            }
            startManagingCursor(cr);
            String[] tasks = new String[] { DBAdapter.KEY_TODO };

Creation of checkbox:

    int[] idchk=new int[al.size()];//here i am creating checkbox dynamicaly
    if (al.size() != 0) {
        chk = new CheckBox[al.size()];
        System.out.println(al.size());
        for (int i = 0; i < al.size(); i++) {
            String[] s = (String[]) al.get(i);
            System.out.println("ID: "+s[0]);
            Task_Id = Integer.parseInt(s[0]);
            Task_Nm = s[1];
            chk[i] = new CheckBox(HomeActivity.this);
            System.out.println(i +"task id"+Task_Id +"parseint"+Integer.parseInt(s[0]+chk[i].getText().toString()));
            chk[i].setId(Task_Id);
            idchk[i]=Task_Id;
            chk[i].setText(Task_Nm);
            //lv1.addView(chk[i]);         
            //setContentView(lv1); 
        }}}

Here what can i write here so that this dynamically created checkboxes will be bind to listview

You can use customized ListView whose rows contains CheckBox. Create your own adapter extending ArrayAdapter and it's overridden method getView create your checkboxes.

What if you use the default listview of android with checkbox. By using :

setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_checked, COUNTRIES));

where COUNTRIES is static final string array that contains the item to show..
