I am creating an android app and need a simple inputText that allows the user to type "tags" very similar to the field of questions here on the site. How do I implement this? Do I need some external library? I’ve reviewed everything and no solution worked 
Thank you very much, this documentation has helped me a lot. But I would like that, in addition to a list of tags already predefined, the user could enter their own freely in case there is n the desired tag in the list. How can I adapt to this feature??

seemed complex at first, but the documentation explains everything you needed.
