QUESTION
I want to display recyclerview items after every 10 seconds. For instance, I have 8 items in my arraylist. Initially I want to display 3 items, then after waiting for 10 seconds first three visible items will disappear and next 3 items will show. how to achieve it ?
...ANSWER
Answered 2021-Jun-14 at 14:12Interesting scenario. I think instead of adding time delays in adapter you should do that stuff in your class where you are passing data to adapter. Try to load first 3 items which you want to show then use handler to make delay of 10 seconds.

QUESTION
I have a song lyrics app with a list of song names and numbers that opens lyrics of selected song. It's list of more than 1000 songs names with numbers that are read by a BufferedReader from a file and placed to ArrayList that is used to make a RecyclerView width CardWidgets. Is there a way to store the genereted ArrayList in internal memory of the phone so the app wouldn't repeat the same process on the start? (Without using a database) Here is some sample code:
ANSWER
Answered 2020-Apr-29 at 00:12No, you cannot continue to use memory after your Java app terminates. All the memory allocated to your app is reclaimed. And if your JVM is terminating as well, its memory is reclaimed.
Even if you were able to maintain data in memory, RAM is completely cleared when the computer or device is shutdown.
Writing data as a file to use later when your app runs again is exactly the purpose of persisting to storage.
In an ideal world, RAM and storage would be one and the same. But we do not live in that world. In our world, RAM is very fast but volatile and expensive while non-volatile storage is cheap but slow.
Reading a thousand short rows from local storage is very fast, imperceptible to the user. That is not a performance problem to be worried about. Beware of premature optimization.
By the way, a library such as Apache Commons CSV can help with the chore of reading/writing tab-delimited or comma-separated values text files.
If you are frequently rewriting the data, then you may want to consider using a database engine such as H2. If you are modifying the data while accessing across threads, then you should definitely be using a database engine such as H2. You would have to research how well H2 works in a memory-constrained device such as Android (I have no experience there).
