RecyclerView项目布局截取当前ItemLayout的屏幕截图

Question

我是Android开发的新手，我有一个recyclerview，其中我正在膨胀不同的自定义视图，如Need Employee，NeedCofounder等。 我正在尝试添加一项功能，以便在社交媒体上分享这些帖子，我无法弄清楚如何获取用户选择分享的当前视图。谢谢

每个布局都有不同的xml文件

我想尝试这样的截图

public Bitmap takeScreenshot() {

        // Cannot figure out how to get the current view 
        View rootView = ????
        rootView.setDrawingCacheEnabled(true);
        return rootView.getDrawingCache();
    }

SharePost按钮

 holder.sharePost.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Bitmap bitmap = takeScreenshot();
        }
    });

Answer 1

   holder.sharePost.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Bitmap bitmap = takeScreenshot();
//getAdapterPosition() will return position of a listview, from that list you can take holder.rootview
            }
        });

Answer 2

<强> RecyclerViewAdapter.class

private View.OnClickListener globalClickListener = new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int selectedPosition = (int) v.getTag();
                // Save selectedPositions on list or do something              
                Bitmap bitmap = takeScreenshot();
            }
        }

<强> RecyclerViewAdapter.onBindViewHolder

holder.sharePost.setTag(position);
holder.sharePost.setOnClickListener(globalClickListener);
