Android Question Explode comma seperated string into a list

tufanv · Jan 10, 2021

Hello,

What is the best way to create a list from a string with values seperated by comma? If the lengths was always same I could use substring2. I can still use substring2 but it won't be a good code. Is there a better way to explode this string into a list ?
For example
s= "USD,TR,MOON"
I want to add all these words into a list

Thanks
