[android-developers] wried UI issue..

[knocker]

I am facing weird UI behavior issue.
When I set *listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);*
onListItemClick behave incorrectly... Let me know if I am missing
anything here.

When I comment following line
    listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

This UI works fine as expected but following part of code doesn't work
    long[] idsList = getListView().getCheckedItemIds();
    Log.i(TAG,"number of rows selected"+idsList.length);

Expected UI change is when i click on one list item it should toggle
its checked state, which does not happen it toggles other list item..
Strange!!!!
