My LoginActivity class and send class works fine if am running the application normally without ViewPager. So i didn’t add the code of those classes here. am just trying to make my app more stylish that’s why am using view pager
Thanks
I think LoginActivity is extending Activity class rather than Fragment class. That is why you are getting classcastException. The class needs to be a Fragment
