Answer 1

试试这个，希望这会对你有帮助......

@Override
public void onListItemClick(ListView list, View v, int position, long id) {
       String hotline = (String) myListData.get((int) id)
                        .values().toArray()[1];

       Log.d("hotline", hotline);
       callHotline(hotline);
    }
}
private void callHotline(String hotlineStr){ 
   Intent callIntent = new Intent(Intent.ACTION_CALL);
   callIntent.setData(Uri.parse("tel:"+hotlineStr));
   startActivity(callIntent);
}

Answer 2

@覆盖 public void onListItemClick（ListView列表，View v，int position，long id） { String hotline = myListData.get（position）;

          Intent tocall = new Intent(Intent.ACTION_CALL);
         tocall.setData(Uri.parse("tel:"+hotline ));
          startActivity(tocall);
    }
}

Answer 3

OnItemClickListener：

@Override
public void onListItemClick(ListView list, View v, int position, long id) {

    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:" + hotlines[position]));
    startActivity(callIntent);

    }
}
