数据绑定中的开关盒 [英] Switch case in Data Binding

问题描述

假设我有3个条件，如

  value == 1然后打印A 
值== 2然后打印B 
值== 3然后打印C 
  

有没有办法使用数据绑定在xml中做这些东西？

我知道我们可以实现条件语句，如

  android：visibility =@ {age< 13？View.GONE：View.VISIBLE} 
  

但是我在搜索switch case语句。

解决方案

不，据我所知，这是不可能的，也会使xml文件真的不可读。我认为最好在业务逻辑中实现，而不是布局文件。

Is it possible to write switch case with android Data Binding?

Suppose i have 3 conditions like

value == 1 then print A
value == 2 then print B
value == 3 then print C

Does there any way to do this stuff in xml by using Data Binding?

I know we can implement conditional statement like

android:visibility="@{age < 13 ? View.GONE : View.VISIBLE}"

But here i am searching for switch case statement.

解决方案

No, as far as I know it is not possible and also would make the xml files really unreadable. I think it would be better to implement this in your business logic, not in layout files.
