                            {

I had the same problem.Finally I solved with this code. Hope It will help you :)

    //layout function
    public void lay_out(List<String> exp1,int k){
    LayoutInflater layoutInflater = 
                (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                container.removeAllViews();
                for(int i=0;i<exp1.size();i++){     
                    final View addView = layoutInflater.inflate(R.layout.row, null);
                    TextView tv=(TextView)addView.findViewById(R.id.textView1);
                    final CheckBox cb=(CheckBox) addView.findViewById(R.id.checkbox1);
                    if(k==0)
                        {
                            cb.setChecked(false);
                        }
                    else

Try this code to get all contacts with checkboxex:

    ma = new MyAdapter();
    lv.setAdapter(ma);
    lv.setOnItemClickListener(this);
    lv.setItemsCanFocus(false);
    lv.setTextFilterEnabled(true);
    // adding
    select = (Button) findViewById(R.id.button1);
    select.setOnClickListener(new OnClickListener() {

        @Override
