Selecting All Items in a Listview on checkbox select

I am using simple listView with

simple_list_item_multiple_choice

I have added a checkbox and on its checked event want all list items to get selected and on unchecked all items to get unselected..
Here is the code..

CheckBox select_all = (CheckBox) dialog.findViewById(R.id.chk_all);
arrayAdapter = new ArrayAdapter<String>
(ctx,android.R.layout.simple_list_item_multiple_choice,readyToDownload );
lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
lv.setAdapter(arrayAdapter);

select_all.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(select_all.isChecked())
{
// check all list items
}
if(!select_all.isChecked())
{
// unselect all list items
}

}
});

Answer
for ( int i=0; i < listview.getChildCount(); i++) {
   listview.setItemChecked(i, true);
}
