如何在函数中将两个参数从1个类传递给另一个？

This is one of the class where i assign data to the item and it return one parameter back to the other class. How should i write it to return two parameter instead? For this case it return final price, how should i write it to return final price and subtotal as well?

这是我将数据分配给项目的类之一,它将一个参数返回给另一个类。我该如何写它来返回两个参数呢?对于这种情况,它返回最终价格,我应该如何写它以返回最终价格和小计?

public static String Final_Price = " ";
public static String subtotal = " ";
protected String doInBackground(String... arg0) {
Final_Price = co.price;
subtotal = co.subtotal;
return Final_Price;
}
@Override
protected void onPostExecute(String result){

   String search = Final_Price;
    ((ReceiptActivity)activity).get_data(search);
}

This is the receipt activity where there is a function to get the data i pass.

这是收据活动,其中有一个函数来获取我传递的数据。

public void get_data (String c)
{
shippingfeeTextView.setText("Shipping fee: " + c);
}

If you want only two parameters, you can use Pair. Source: http://developer.android.com/reference/android/util/Pair.html
