Question

I am trying to add the items from my array into the listview but i always get an exception.

below is the code of how i add the items:

items.add(new SectionItem("President"));
                for(int a = 0; a <= presList.size(); a++)
                {
                    String name = presList.get(a);
                    String companyName = presList.get(a + 1);
                    Log.d("company name:", companyName);
                    items.add(new EntryItem(name,companyName));
                }

Logcat Output:

Answer 1

use

for(int a = 0; a <= presList.size()-1; a++)

OR

for(int a = 0; a < presList.size(); a++)

instead of

for(int a = 0; a <= presList.size(); a++)
