How to build query to diplay data in descending order i.e. last node first please help

nice tutor brother.. :)

Hello Sir nice tutorial. I just have a question, I plan on writing over my Listview into a recycler view like yours. I was having some trouble with my list view in that it changes the order whenever I get back to the activity after being in the background. Does the recycler view take care of that problem? I read around I heard that these types of views reloads data from the cache which can cause a problem with the ordering...and I was wondering if your method takes care of that situation.

I need to put a search button. Can you help me?

How do I do a searchview? Thank you ...

hi, can you please make a firebase-ui pagination adapter tutorial..? i successfully implemented firebase-ui recyclerAdapter. getting snapshots was easy on this using adapter position and getSnapshots().getsnapshot() methods . but unfortunately they don't have this methods on paginationAdapter.. please help i need this to implement on item clicks on each documents and modify them according their doc id.

can you implement Collections.shuffle() in your code to shuffle the data in recycler view and if so how to? :)

hi how can i implement that pagination if i use firebaseui because i dont have a list items in my codes or should i switch back to firebase instead

You dont have to pass context, you can get context from the view by doing view.getContext();

Hi Eddy, i have this error trying to test: Default FirebaseApp is not initialized in this process com.ffrowies.firebaserecyclerviewpaging. Make sure to call FirebaseApp.initializeApp(Context) first. (same problem in project Firebase Recylcer View Item Multiple Type).

Instead of making a Query to get last key then creating an IF statement after FOR loop comparing lastNode and lastKey, I would suggest you create 2 fixed lines after FOR loop:

take last item in ArrayList and set its key as a value for lastNode variable.
next line, remove last item from ArrayList

Your concept is not working on fragments. open other activity and them come back to that fragment list goes blank. Same thing is happening on activity. If I start another activity and then come back to the activity list goes blank. Fix this

sorry before
i want to ask something different.
how to get id from json? ive put my json with my own id just like '1' '2' '3' to firebase
and i want to get the id for the new activity based on its id.
hope you answer my question.

link to database is not working

Damn it. Scrolling is infinite now...

Awesome! Works fine

RecyclerView: No adapter attached; skipping layout
