Recyclerview将每个子视图创建为单独的位图

Question

我想为所有recyclerview项目创建位图。以下代码仅适用于可见项目。如果我手动滚动，那么它可以捕获。

我想不滚动。任何人都可以帮忙。

View u = holder.ll;
holder.ll.measure(View.MeasureSpec.makeMeasureSpec(595, View.MeasureSpec.EXACTLY), View.MeasureSpec.makeMeasureSpec(824, View.MeasureSpec.EXACTLY));
                u.setDrawingCacheEnabled(true);
                int totalHeight = holder.ll.getMeasuredHeight();
                int totalWidth = holder.ll.getMeasuredWidth();
                u.layout(0, 0, totalWidth, totalHeight);
                u.buildDrawingCache(true);
                Bitmap b = Bitmap.createBitmap(u.getDrawingCache());
                bitmaps.add(b);
                u.setDrawingCacheEnabled(false);
