editsearch.setOnKeyListener(new OnKeyListener()
{
    public boolean onKey(View v, int keyCode, KeyEvent event)
    {
        if (event.getAction() == KeyEvent.ACTION_DOWN)
        {
            switch (keyCode)
            {
                case KeyEvent.KEYCODE_DPAD_CENTER:
                case KeyEvent.KEYCODE_ENTER:
                    String text = editsearch.getText().toString()
                    .toLowerCase(Locale.getDefault());
                    adapter.filterstd(text);
                    return true;
                default:
                    break;
            }
        }
        return false;
    }
});
