How can we handle multiple exo player in a recycler view? I saw many posts and videos like this and this but that all use a custom recycler view class. I could continue with that. But, I wanted to make a complete Insta clone where I can send gif and image and videos. Now, when I use the custom recycler view class, I dont have any idea of how to play the video with the gif and images. This is my recycler view item code:

I got it. I got it. AND I GOT IT. I just made a class where I created an static var? of ExoPlayer class which looked like this:
import android.annotation.SuppressLint
import com.google.android.exoplayer2.ExoPlayer
@SuppressLint("StaticFieldLeak", "Deprecation")
class ExoPlayerPlaybackHelper {
companion object{
var playerView : ExoPlayer? = null
}
}
Then, I used this in my model(data class) to create an object of ExoPlayer with a play function in it and in the end, my model looked like this:
import com.google.android.exoplayer2.ExoPlayer
import com.sambhav2358.facebookclone.utils.ExoPlayerPlaybackHelper
data class Post(my params, var playerView: ExoPlayer?){
fun playVideo(playerView : ExoPlayer) {
ExoPlayerPlaybackHelper.playerView?.pause()
ExoPlayerPlaybackHelper.playerView = playerView
playerView.play()
}
constructor() : this(my params, null)
}
Now, in the adapter, I pass my exo player to my data class's object like this:
post.playerView = binding.videoView.player as ExoPlayer
The last task was to stop and play the video according to the scroll position using the OnScrollListener. I used this code and it did the task for me:
binding.recyclerView.addOnScrollListener(object : RecyclerView.OnScrollListener() {
override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
val pos = (recyclerView.layoutManager as? LinearLayoutManager)?.findLastCompletelyVisibleItemPosition()
if (pos == -1) return
Log.d(TAG, "onScrolled: Scrolled $pos")
if (posts[pos!!].messageType == "video" || posts[pos].messageType == "messageVideo") { // you might remove this line If you only use video players. But, I needed it.
posts[pos].playVideo(posts[pos].playerView!!)
Log.d(TAG, "onScrolled: played")
}
Log.d(TAG, "onScrolled: startCheckPauseTask")
for (position in posts.indices){
if (position == pos) continue
posts[position].playerView?.pause()
}
Log.d(TAG, "onScrolled: finishCheckPauseTask")
}
})
