a local service app with worker and user registration and log in and where the user can view different categories of the services being offered an can pay, write reviews and rate the workers in android studio using java. The app should connect to firebase where there will be two databases, for the user and for the worker. there should be a categories button at the home page that when pressed will give a list of the names of the workers in that category and each name will be clicked to give additional information such as name, email address, phone number and a place for the users to rate stars and write reviews

i tried connecting to firebase and creating a database but it didn’t work. i found it hard to modify the recyclerview to give a list of items
