Items disappears while scrolling Gridview very fast. Also the image dimension changes while scrolling fastly

Items disappears while scrolling Gridview very fast. Also the image dimension changes while scrolling fastly. Here is my code :

 public View getView(final int position, View gridView, ViewGroup parent) {

            final ViewHolder holder;

            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            if (gridView == null) {
                holder = new ViewHolder();

                gridView = new View(context);
                gridView = inflater.inflate( R.layout.view_initial_gallery, null);
                holder.dirname = (TextView) gridView.findViewById(R.id.fname);
                holder.dirimg = (ImageView) gridView.findViewById(R.id.folder);
                holder.tick = (ImageView) gridView.findViewById(R.id.tick);

                File file=folders.get(position).getFilelist().get(0);
                holder.dirname.setText(folders.get(position).getFoldername());
                Picasso.with(context)
                        .load(new File(file.getPath()))
                        .resize(300, 300)
                        .centerCrop()
                        .into(holder.dirimg);

                gridView.setTag(holder);

            }
            else
            {
                holder = (ViewHolder)gridView.getTag();
            }
            return gridView;
        }

I have fixed the issue with notifyDataSetChanged(). Hope it will work for you also.

mGridView.setOnScrollListener(new AbsListView.OnScrollListener() {
   //     Boolean isScrollStop=false;
        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {

            if (scrollState == AbsListView.OnScrollListener.SCROLL_STATE_IDLE) {
                  mAdapter.notifyDataSetChanged();
            } 
        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                             int visibleItemCount, int totalItemCount){

        }
    });

I had the same issue, except that I used Glide instead of Picasso for image loading. I'm guessing your ImageView's dimensions are set to wrap_content. Try setting height and width to explicit values in dp's, it worked for me.
