How delete Row from list view on "onMenuItemSelected" ?

@Override
   public boolean onMenuItemSelected(int featureId, MenuItem item) {
       // TODO Auto-generated method stub

       switch (item.getItemId())
       {
           case Menu.FIRST:
               // getting values from selected ListItem
               String URL = ((TextView) findViewById(R.id.txt_link)).getText().toString();

               // Starting new intent
               Intent i = new Intent(getApplicationContext(), ShowNewsActivity.class);
               i.putExtra("URLname", URL);
               startActivity(i);
               break;
           case Menu.FIRST + 1:
               Toast.makeText(this, "Exit Clicked for context menu", Toast.LENGTH_LONG).show();

               break;
       }
       return super.onMenuItemSelected(featureId, item);
   }
