这是我的解决方案，
LinearLayoutManager当 所有项目的尺寸都相同 并且 只有一种类型的项目时
。此解决方案基于此答案。
注意 ：这可能会导致内存不足错误。
public static Bitmap getRecyclerViewScreenshot(RecyclerView view) { int size = view.getAdapter().getItemCount(); RecyclerView.ViewHolder holder = view.getAdapter().createViewHolder(view, 0); view.getAdapter().onBindViewHolder(holder, 0); 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(); bigCanvas.drawBitmap(holder.itemView.getDrawingCache(), 0f, iHeight, paint); iHeight += holder.itemView.getMeasuredHeight(); holder.itemView.setDrawingCacheEnabled(false); holder.itemView.destroyDrawingCache(); } return bigBitmap; }注意2： 它最初是用Kotlin编写的。这是我使用的原始代码。
