How to disable image reloading in recyclerview

Question

In my recyclerview, if I scroll up/down images are reloaded again. it spoils user experience.

I know its default behavior of recyclerview. But I want to implement same like Whatsapp. They do not reload image if already loaded. Anyone suggest to me.

My Glide library code:

   BitmapTypeRequest glideRequestmgr = Glide.with(context).load(getGlideURL(path, context)).asBitmap();

        glideRequestmgr.diskCacheStrategy(DiskCacheStrategy.ALL)
                .dontTransform()
                .dontAnimate()
                .into(new SimpleTarget<Bitmap>() {

                    @Override
                    public void onResourceReady(Bitmap arg0, GlideAnimation<? super Bitmap> arg1) {
                        imageView.setImageBitmap(arg0);
                    }
                });

Finally I fixed that issue by put the recyclerview inside NestedScrollView

Step 1:

<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</android.support.v4.widget.NestedScrollView>

Step 2:

recyclerView.setNestedScrollingEnabled(false);
