how to handle checkbox in listview android?

Question

I am using checkbox with ListView.Code is working fine. I strucked to get all the list checked Items. I used below code for getting checked items. But it is giving result of focused area of list.

int firstPosition = list.getFirstVisiblePosition();

        for(int i = firstPosition; i < list.getCount(); i++){
            View v = list.getChildAt(i);
            if(v != null){
                cbx = (CheckBox)v.findViewById(R.id.c_checkbox);
                if(cbx.isChecked()){
                                        //adding this check box to one sub list
                }
            }
        }

But it is giving only focusable list items result only.Depending on sublist I want to populate my menu that's why I am using this code in onPrepareOptionsMen() method and clicking on menu item delete this list from database. I found another solution that is

long checkedPos[] =list.getCheckedItemIds();

But it is giving

01-31 12:07:16.042: WARN/dalvikvm(294): VFY: unable to resolve virtual method 808: Landroid/widget/ListView;.getCheckedItemIds ()[J 01-31 12:07:16.042: WARN/dalvikvm(294): VFY: rejecting opcode 0x6e at 0x0024

This error. After searching on Google I found another solution that is

but I want to use SparseBooleanArray into my activity onPrepareOptionMenu().How to get back this result into my activity from my adapter.Please give me advice?

At last i used SparseBooleanArray.Now it is working fine. Regards, Android developer

D'you set choiceMode to something defferent than CHOICE_MODE_NONE (see setChoiceMode docs) — Olegas
