I am trying to achieve what should be a very simple task. Create a
ListView that allows multiple selection, set some initial values
selected, display the ListView and then retrieve the selected items
once the user has finished manipulating the list.
I have a custom dialog with a ListView and the following in the
constructor
ListView theList = (ListView)
findViewById(R.id.excluded_apps_list);
theList.setItemsCanFocus(false);
theList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
ArrayAdapter<String> arrayAdapter = new
ArrayAdapter<String>(context, R.layout.appspicker_itemview, test);
theList.setAdapter(arrayAdapter);
for (String s : _itemNames) {
arrayAdapter.add(s);
}
theList.setItemChecked(0, true);
The list displays fine and the first item is checked as expected.
Once the dialog closes I do the following to get the checked item
positions:
ListView theList = (ListView)
findViewById(R.id.excluded_apps_list);
SparseBooleanArray checked = theList.getCheckedItemPositions();
The problem is that even if I deselect the first item and then close
the dialog, getCheckedItemPositions() still indicates that the item is
checked. If I remove the call to setItemChecked(), everything works
fine but I really need the ability to set the inital checked state of
the list items.
Any ideas what I'm doing wrong?
