I have a RecyclerView in which each item contains a button that plays sound from online url.
The problem is that I don't want the items to play sound at the same time and when you click on different sound, the previous one gets off but I don't know how can I do that ?
I would be appreciate if you could guide me through this problem

when i click on the each item it get expanded and previous sound gets off but the button still shows in pause mode not play mode and I don't want the sound gets off when I expand a new item and I want that it gets off when I click on the next button just in a case that you pause previous button it works but I want automatically it gets off when I click new play button and the previous one gets completely off I would be so grateful if you could help me to fix my code and show me how can I edit it
