Try to do like this. hope it will help you...

editsearch.addTextChangedListener(new TextWatcher() {

    @Override
    public void afterTextChanged(Editable arg0) {
        // TODO Auto-generated method stub
    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1,
            int arg2, int arg3) {
        // TODO Auto-generated method stub
    }

    @Override
    public void onTextChanged(CharSequence arg0, int arg1, int arg2,
            int arg3) {
        // TODO Auto-generated method stub
        editsearch.requestFocus();
        final ArrayList<Item> itemArray = new ArrayList<Item>();
        int textlength = 0;
        textlength = editsearch.getText().length();
        itemArray.clear();
        for (int i = 0; i < item.size(); i++)
        {
            String itemTitle = item.get(i).name();
            String compareItemTitle = "";
            if (textlength <= item.length())
            {
               compareItemTitle = (String) itemTitle.toLowerCase().subSequence(0, textlength);
               if(compareItemTitle.contentEquals(editsearch.getText().toString().toLowerCase()))
               {
                    itemArray.add(item.get(i));
               }
            }
        }
        adapter = new MyAdapter(AddToOutlet.this, R.layout.addtooutlet_list_item, itemArray);
        lv.setAdapter(adapter);
}

    }
});

Try this way, this is exactly what you looking for

   @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // adds item to action bar
        getMenuInflater().inflate(R.menu.search_main, menu);

        // Get Search item from action bar and Get Search service
        MenuItem searchItem = menu.findItem(R.id.action_search);
        SearchManager searchManager = (SearchManager) MainActivity.this.getSystemService(Context.SEARCH_SERVICE);
        if (searchItem != null) {
            searchView = (SearchView) searchItem.getActionView();
        }
        if (searchView != null) {
            searchView.setSearchableInfo(searchManager.getSearchableInfo(MainActivity.this.getComponentName()));
            searchView.setIconified(false);
        }

        return true;
    }
