如何更改列表视图的背景颜色？

Question

my array list data:
John
John
Jack
Peter
Parker

the repeated names must have different background in the list view

how to do that?

ArrayList<listitem> data=
(ArrayList<listitem>)bundle.getSerializable("value");

sentItems = data; //names John,John,Jack....

final List<listitem> duplicates = new ArrayList<listitem>();
Set<listitem> listitemSet = new TreeSet<listitem>(new Comparator<listitem>() {
@Override
public int compare(ListItem o1, ListItem o2) {
return o1.getTitle().compareTo(o2.getTitle());
}
});
for(ListItem c : sentItems)
{
if(!listitemSet.add(c))
{
duplicates.add(c); //similar names added to the new list
}
}
