当onBindViewHolder多次调用时，如何防止在RecyclerView中多次加载位图？

Question

我有使用GridLayoutManager的recyclerView， recyclerView项目由ImageView和自定义进度组成，随着时间的推移更新，但我不需要每次都加载位图，只需要进度。这就是我使用magazineId的原因，当它只是在那种情况下是空的加载位图，但无论如何它会不时地加载位图，这与我在使用LinearLayoutManager时没有相同。

 @Override
public SimpleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.library_item, parent, false);
    SimpleViewHolder viewHolder = new SimpleViewHolder(view);
    viewHolder.id = "NONE";
    return viewHolder;
}


@Override
public void onBindViewHolder(final SimpleViewHolder viewHolder, final int position) {
    final Magazine magazineItem = magazines.get(position);
    String magazineId = magazineItem.getId();

    if (!viewHolder.magazineId.equals(magazines.get(position).getId())) {
        viewHolder.layoutCoverContainer.setLayoutParams(new LinearLayout.LayoutParams(200, coverHeigth));
        gDisplayImage(new GlideImage(magazines.get(position).getFirstPage(), true), viewHolder.glideView);
        viewHolder.magazineId = magazines.get(position).getId();
    }
viewHolder.customProgress.setPercent(percent);
}
    public void setMagazines(List<Magazine> allMagazines) {

    if (allMagazines != null) {
        if (magazines == null) {
            magazines = new ArrayList<Magazine>();
        } else {
            magazines.clear();
        }
        if (allMagazines != null) {
            magazines.addAll(allMagazines);

        } else {
            magazines.clear();
        }
    }
    notifyDataSetChanged();
}
 public class SimpleViewHolder extends RecyclerView.ViewHolder  {
    GlideViewglideView;
    String magazineId;}

 <android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:clipToPadding="false" />



    private void setUpSwipRecyclerView() {
    mRecyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);

    mRecyclerView.setLayoutManager(new GridLayoutManager(getContext(),2));
    mRecyclerView.setAdapter(libraryAdapter);
}
