如何在Android Studio中访问和连接两个SQLite数据库？

I have 2 SQLite databases in my android project, 1 is used to store profile details of users and another one stores book appointments. Currently the two do not link but work fine. I might sound a bit stupid, but is it possible to connect the two so when some clicks on the booked appointment of a certain user it will go to their profile. I cannot see a way how this can be possible and after spending quite a well I've not been proven right.I have 2 SQLite databases in my android project
