java - List in Android: Rename duplicated items -

i want create lists follows:

• list-item
• list-item-1
• list-item-2
• list-myitem
• list-myitem-1

as above list-item, if item's name same in next row, add suffix 1.

like done upto enter image description here

ok, want ask how implement this. simple solution can think of using map<string, int> keep track of item name. code this:

final map<string, integer> listnamemap = new hashmap<string, integer>();

when displaying list item name, you'll do:

final string displayedname; if (listnamemap.containskey(name)) {    integer newvalue = listnamemap.get(name).intvalue() + 1;    listnamemap.put(name, newvalue);    displayedname = name + "-" + string.valueof(newvalue); } else {    listnamemap.put(name, 0);    displayedname = name; } // use displayedname display
