How to use the search bar in each recyclerview line

Question

I have a situation where I need to show the search bar in each line of recylerview to load media (audio). The file started successfully, but every time I click the downlaod button, only the last recylerview search bar does not work for the search associated with a particular line.

This is my adapter, where do I download audio from

Answer 1

Check out the concept of view tags that will help you. basically do seekbar.setTag ("UNIQUE ID FOR EVERY VIEW"); then when updating the search engine, use findViewWithTag ("UNIQUE ID FOR A SPECIFIC VIEW")

id, .
