I have a RecyclerView. Each row has a play button, textview and Progressbar. when click on the play button have to play audio from my sdcard and have to progress Progressbar The problem is when i scroll down the recyclerview change the Progressbar in next row.means I can fit 5 items on the screen at once. When I scroll to the 6th, 6th row seekbar changes suddenly.

Please try this
If you are using ListView
- override the following methods.
@Override
public int getViewTypeCount() {
return getCount();
}
@Override
public int getItemViewType(int position) {
return position;
}
If you are using RecyclerView
- override only getItemViewType()
method.
@Override
public int getItemViewType(int position) {
return position;
}
