Recyclerview Changing Items During Scroll


Please try this

  1. If you are using ListView - override the following methods.

     @Override public int getViewTypeCount() {         return getCount(); } @Override public int getItemViewType(int position) {         return position; }
  2. If you are using RecyclerView - override only getItemViewType() method.

     @Override public int getItemViewType(int position) {         return position; }


Add setHasStableIds(true); in your adapter constructor and Override these two methods in adapter. It also worked if anyone using a RecyclerView inside a ViewPager which is also inside a NestedScrollView.

@Overridepublic long getItemId(int position) {            return position;}@Overridepublic int getItemViewType(int position) {       return position;}


As the name implies, the views in a RecyclerView are recycled as you scroll down. This means that you need to keep the state of each item in your backing model, which in this case would be a Historyitem, and restore it in your onBindViewHolder.

1) Create position, max, and whatever other variables you need to save the state of the ProgressBar in your model.

2) Set the state of your ProgressBar based on the data in your backing model; on click, pass the position of the item to your FileDownload/StartMediaPlayer methods.

public void onBindViewHolder(final RecyclerView.ViewHolder viewHolder, int position) {    final Historyitem dataItem = stethitems.get(position);    final MyViewHolder myViewHolder = (MyViewHolder) viewHolder;    myViewHolder.progressplay.setMax(dataItem.getMax());    myViewHolder.progressplay.setProgress(dataItem.getPosition());    ...    myViewHolder.stethstreamplay.setOnClickListener(new View.OnClickListener() {        @Override        public void onClick(View view) {               FileDownload(dataItem.getmsg(), position);        }    });

3) Update the progress bar by updating the backing model and notifying that it was changed.

stethitems.get(position).setPosition(mPlayer.getCurrentPosition());notifyItemChanged(position);
