Thank You

For those who are getting an error when you create an instance of ArtistList adapter = new ArtistList(MainActivity.this, artistList);

If you have a fragment you can just replace MainActivity.this to getActivity()

After many frustrating hours search for a simple list view you have given me the perfect answer which is easy to follow. Thank you so much for your interesting series

Hey guys.. i want to thank u all from simplified coding ..u guys helps me alot in my project! Thank you so much !! 😊

Very nice explanation of all the codes. Awesome. But I have a query, if we are making a chat application using these same features how can we send notifications to all the devices when any new data is added to the database. Please help.

[Bluemoonredwine]

this is an awesome tutorial. I am a beginner and was able to follow all the steps very clearly and it works!
an added question if you have time: how would i make it so that the list can be shown reversed (with the most recent added item on top?)

[zuhairhd]

thank you ... your explanation is clear and easy to follow ... good luck in your career

[akshil]

This was what i specifically looking for thank you :)

Thank you sir, you're a life savior😇 may god bless you

[mervinlee]

Another good tutorial but how can you make the spinner scroll smoothly?

[hubertmikulowskinjuacha]

It might be preferable to attach a "ChildEventListener" than "ValueEventListener". The former has more precise override functions that would reduce lines of code and probably the amount of data downloaded.

What if you want to list your artists on a different screen? Not on the same screen you're adding artists?

good video, a question i have: why use an array adapter? what is the purpose

[malhartanksale]

Great Video... I have one question regarding this and that is"If i have to display the retrieved data on the other activity then how it will be possible?" Please let me know

[kamranahmed]

very nicely explained. it will be great if each thing like parameters, constructors their linkage is elaborated. Thanks

[pengyouglobalsystems]

Thnakyou so much for your videos... its working perfectly and more helpful...

Note, that instead of creating new ArtistList adapter each time new artist is added, you could add a method to your ArtistList adapter, that would change the underlying data array and notify the View that the data has been changed, so that the view redraws the list anew. This way you re-use the already bound instance of the adapter. It would be even better to tell the adapter that new item is to be added, and let it handle the underlying data storage (encapsulation), and notification to the view such that you optimise the drawing of the ListView to only re-draw what is needed (new item), instead of re-drawing the entire list.

thanks, , ., .nice tutorial, , can you tell me how can i show update item in the top of list view.

[tabishkhan]

Is that possible to store data from one application and Retrieving data into another application?
