I've implemented a Recycler view of video players implemented using a texture view and media player.
If I scroll down through the list I can click on the item and the video plays. However, with the recycler view once the view goes off screen it is then recycled for reuse. If I scroll back up all the views are now blank (black).
I am looking to add functionality that when the user scrolls the video off screen that it will pause and keep reference to that video so that if they scroll back to that video it will play from that point.
I have checked this out however I don't want to download the video, I just want to stream. I am not looking for someone to do this for me, I'm just looking for some pointers and hoping someone could share their knowledge on this... Thanks in advance
This is what I have done so far:
