如何在Android和IOS应用程序中正确显示来自MySQL数据库的选项卡（空白）？

Question

I have following data in my db row:

Espresso:                           7,00

Double Espresso:                    8,00

Ristretto:                          7,00

Espresso Machiato:                  8,00

Espresso Con Panna:                 8,00

I write it on Word, then copy & paste to MySQL editor. When I save it, my IOS and Android apps cannot show the prices aligned because of the tab characters.

What is the best way to do that?

Answer 1

The best way- those 2 things are different data and are in different columns in your database, I would expect (if not, you need to fix your schema). So put the 2 strings in separate TextViews, and align the text view in xml.

Answer 2

First you can split the data from tab character and use formatting like below in java. I believe in objective-c it should be similar.

    String ehe = String.format("%-20s : \t %4dTL \n","ehemehe",23);
    String ehe2 = String.format("%-20s : \t %4dTL \n","ehemeheadawd",44);
    System.out.println(ehe);
    System.out.println(ehe2);

Output it produces is

ehemehe              :     23TL 

ehemeheadawd         :     44TL

Answer 3

replace the "/t" chars with "" before you display the text. by using

String.replace("/t","");

Answer 4

如果您预先计算了空格数，请使用固定宽度的字体。
