How can I retrieve all data from these keys and display it in recycle view. Each key has a value that I want to display.

Simply adding a ValueEventListener to correct child

database.child("user details").addValueEventListener(...

would do it. You might want to consider changing "user details" to one word, eg. "userDetails".

  • If it must be `User details` with a space and it's only for android you can use the @PropertyName(String) to name the variable something different, or just use a Map. – Torewin May 02 '18 at 04:17
