I want to display hashtags in the android Edit-text when user types the keyword, and then hits "Space" then Edit-text takes that keyword automatically. here i have attached one screen shot. i need that kind of functionality.User can also remove the hashtag individually and all the hashtags by clicking cancel button.
Need functionality exactly same like when we entering the tags in the stackoverflow when asking a question.
Check this library - it provides basically the same functionality as you requested.
