User tagging View/EditText android


I’ve been searching online or maybe i do not know the right keywords for it, but is there a custom EditText view where when user types the ‘@’ sign, a list of suggestions / usernames displays (More like user tagging in comments for Facebook and Stackoverflow)? All I could find online are the ‘tags’ view where words are placed inside a view with corner radius and an ‘x’ close button. If there isn’t I’m thinking of creating my own EditText, but I want to save time creating one if there already exists a resource online. Pardon for a noob question. Thanks in advance
