Recyclerview Changing Items During Scroll

Question

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

Answer 1

This is the expected behaviour of recyclerView. Since the view is recycled your items may get into random views. To overcome this you have to specify which item is put into which kind of view by yourself. This information can be kept in a SparseBooleanArray. what you can do is create a SparseBooleanArray in your adapter like this

SparseBooleanArray selectedItems = new SparseBooleanArray();

whenever your view changes, do:

selectedItems.put(viewItemIndex,true);

Now in your onBindViewHolder do

 if(selectedItems.get(position, false)){
    //set progress bar of related to the view to desired position
    }
    else {
        //do the default
    }

This is the basic to solve your problem. You can adjust this logic to any kind of similar problem in recyclerView.
