android list elements from an array list

Question

I have the followig list:

List<String> item = new ArrayList<String>();

It contains a list with fruites. How to filter the list after the first 1 or 2 or three characters from an element (startsWith()) and display the first element from the list after it is filtered?

Can someone please give me an example?

Appreciate!!

you can use collection for this

 Collections.sort(item, new Comparator<String>() {
    @Override
    public int compare(String s1, String s2) {
        return s1.compareToIgnoreCase(s2);
    }
});

those are the strings from your list. Please take a look at the sources of Collections.sort method if you want to get more details on that – Ram kiran Pachigolla Jul 23 '12 at 11:02

This can help you.

Add TextWatcher to EditText#addTextChangedListener
In onTextChanged add or remove items from your ListView's adapter.
