android - Get all ListView items(rows)

How may I get all children of an item of ListView ?
There are methods to get child at position but I was not able to find any method which returns collection of all children in an item of ListView.

Update : I just found out that I need ListView items(rows) instead. How may I achieve this ?
What I am doing is, comparing the selected ListView item with all items.

You get all list item from list adapter through iteration as below

for (int i=0;i<adapter.getCount();i++){
     adapter.getItem(i);
}

Update : You can compare specific item using index with list adapter all items as below :

for (int i=0;i<adapter.getCount();i++){
    if(adapter.get(selectedIndex)==adapter.getItem(i)){
       // TODO : write code here item match 
       break; // after match is good practice to break loop instead compare rest of item even match
    }
}
