Hi, guys
I'm now developing an application that uses a ListView with a
CheckedTextView on every item that managed by an ArrayAdapter to
support multiple chooses. The contents in my ListView are dynamic, that
means, can be changed during runtime. Now I try to use
ListView.getCheckedItemPositions() to get all checked items, Because I want
to save all the checked positions and auto-check them when user go back to
this page again. So I need to save checked results for every page.
Here is code that I uses to retrieve the checked item positions:
public void addDirSel(String dir, ListView lv) {
List<Integer> l = null;
SparseBooleanArray positions = lv.getCheckedItemPositions();
for(int index =0 ; index < lv.getCount(); index++) {
if (positions.get(index, false) == true) {
if (l == null) {
l = new ArrayList<Integer>();
}
l.add(index);
}
}
addDirSel(dir, l);
}
My questions is:
For the first page everything works fine as expected. But when user goes to
another page and make some chooses, the result array that ListView returned
contains some positions that are never checked. I don't why ListView has
this strange behavior. Even for a page that in fact no checked happens but
ListView gives me a result that indicates there's one item has been checked.
Thanks for your help
Alex,
