Getting gaps between recyclerview items after scrolling down and then scrolling up again. Please see details

Question

I have a RecyclerView in which I'm loading some items from the database.

The problem is that I'm getting some gaps between the items after scrolling down and up again. The gaps then remain there until I restart the app. Like this:

Here's how I have set up recyclerview in xml layout:

<android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clipToPadding="false"
        android:scrollbars="vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

Here's how I have set it in MainActivity.java file:

recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerView.setAdapter(fastItemAdapter);

Here's the adapter:

public class HRequest extends AbstractItem<HRequest, HRequest.ViewHolder> {

        public String imageURL;

        public HRequest() {

        }

        public HRequest(String imageURL) {
            this.imageURL = imageURL;
        }

        // Fast Adapter methods
        @Override
        public int getType() {
            return R.id.recycler_view;
        }
        @Override
        public int getLayoutRes() {
            return R.layout.h_request_list_row;
        }
        @Override
        public void bindView(ViewHolder holder) {
            super.bindView(holder);

            holder.imageURL.setText(imageURL);

        }
        // Manually create the ViewHolder class
        protected static class ViewHolder extends RecyclerView.ViewHolder {

            TextView imageURL;

            public ViewHolder(View itemView) {
                super(itemView);
                imageURL = (TextView)itemView.findViewById(R.id.imageURL);

if (!imageURL.getText().toString().isEmpty()) {

if (imageURL.getText().toString().startsWith("https://firebasestorage.googleapis.com/") || imageURL.getText().toString().startsWith("content://")) {
                    Picasso.with(itemView.getContext())
                            .load(imageURL.getText().toString())
                            .into(homelessImage);
                } else {
                    Toast.makeText(itemView.getContext(), "some problem", Toast.LENGTH_SHORT).show();
                }

            } else {
                Toast.makeText(itemView.getContext(), "no imageUID found", Toast.LENGTH_SHORT).show();
            }

            }
        }

    }

What is wrong here?

Please let me know.

I don't see any problems in your code. Post code of base adapter class and item layout, maybe it contains some bugs. — Denis Sologub, Jun 23 '16 at 19:36
