How to retrieve data from the firebase and show inside the CardView nicely

I have created the CreateEvent.java module to upload the data to firebase. But how to retrieve the data and show in the Cardlist? For example show in the xml file below. And also if there was more than 1 data in firebase, how to show in with multiple cardlist that I have created in the xml file?
