multiple-select

I have this vector v = (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,18,19,20) I want to remove the multiples of 2 and 3. How would I do this?

I'm beginner in Django/Python and I need to create a multiple select form. I know it's easy but I can't find any example.

I have a ListView with a custom adapter. The ListView allows multiple select, but somehow it's not recognising when an item is selected. I've already made the adapter items extend Checkable, but still the getCheckedItemPositions() returns an array of falses. I guess there's something fundamental I'm doing wrong, but I have been unable so far to find examples of multiple select ListViews where the adapter was not an ArrayAdapter using the default layout for multiple selects. Any help would be much appreciated. Code is below: Main class: listView = (ListView) findViewById(R.id.cardlist); tca =
