@anjandev thanks a lot for the PR!

Are these "Expand" links always shown, or only when the text exceeds a certain lenght?

[grote]

Why do we need to add this? I don't really understand the chinese on the libraries' page.

No problem. Thank you for reviewing.

Expand is only shown when text exceeds a certain length. See: https://user-images.githubusercontent.com/8602360/46909957-af371980-cf2a-11e8-926d-e9cf8cf58eee.png

I dont understand chinese either but this was the only library I could make work. Furthermore, this library allows us to have the simpliest code. I deleted the attr file and the code compiles and runs fine. I just made a new commit deleting the attr file. Thanks for the feedback.

@grote Is there any reason this was never merged and is there anything I can do to get it into a state that can be merged?

Where does the Expand text come from? Can it be localized into other languages by Transportr's translators?

What happens if some notices are expanded and some or not and you rotate the screen? Does this library maintain the expanded state across configuration changes?
