Take a screenshot of RecyclerView in FULL length .. each item having a list

Question

I am using a recyclerView having lists of dynamic sizes...and when i use this method to take screenshot of each recyclerView item.. it taking the screenshot but each item containing only one list item each.. even if the list item size > 1.

public static Bitmap getRecyclerViewScreenshot(RecyclerView view) {
    int size = view.getAdapter().getItemCount();
    RecyclerView.ViewHolder holder = view.getAdapter().createViewHolder(view, 0);
    view.getAdapter().onBindViewHolder(holder, 0);
    ArrayList<Bitmap> bitmaps=new ArrayList<>();
    holder.itemView.measure(View.MeasureSpec.makeMeasureSpec(view.getWidth(),
            View.MeasureSpec.EXACTLY),
            View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
    holder.itemView.layout(0, 0, holder.itemView.getMeasuredWidth(), holder.itemView.getMeasuredHeight());
    Bitmap bigBitmap = Bitmap.createBitmap(view.getMeasuredWidth(), holder.itemView.getMeasuredHeight() * size,
            Bitmap.Config.ARGB_8888);
    Canvas bigCanvas = new Canvas(bigBitmap);
    bigCanvas.drawColor(Color.WHITE);
    Paint paint = new Paint();
    int iHeight = 0;
    holder.itemView.setDrawingCacheEnabled(true);
    holder.itemView.buildDrawingCache();
    bigCanvas.drawBitmap(holder.itemView.getDrawingCache(), 0f, iHeight, paint);
    holder.itemView.setDrawingCacheEnabled(false);
    holder.itemView.destroyDrawingCache();
    iHeight += holder.itemView.getMeasuredHeight();
    for (int i = 1; i < size; i++) {
        view.getAdapter().onBindViewHolder(holder, i);
        holder.itemView.setDrawingCacheEnabled(true);
        holder.itemView.buildDrawingCache();
        bitmaps.add(holder.itemView.getDrawingCache());
        bigCanvas.drawBitmap(holder.itemView.getDrawingCache(), 0f, iHeight, paint);
        iHeight += holder.itemView.getMeasuredHeight();
        holder.itemView.setDrawingCacheEnabled(false);
        holder.itemView.destroyDrawingCache();
    }
    return bigBitmap;
}



  Here is my screenshot attached (`of each item of recyclerView`)!! It should show `two items` but uniformly its showing `1 item` each ` I am facing problem with the `inner listView` 

Original is :-

Screenshot is :-

Its the case for each and every recycler item screenshot only 1 item is shown.

faced the same issue and resolved this by using this piece of code.

First of all, ask your view to calculate it's measurements and then ask view to give MeasuredHeight and all done.

recyclerView.measure(
        View.MeasureSpec.makeMeasureSpec(recyclerView.getWidth(), View.MeasureSpec.EXACTLY),
        View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));

Bitmap bm = Bitmap.createBitmap(recyclerView.getWidth(), recyclerView.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
recyclerView.draw(new Canvas(bm));

saveImage(bm);
ImageView im
          = new ImageView(getActivity());
im.setImageBitmap(bm);
 new AlertDialog.Builder(getActivity()).setView(im).show();
