I have a ViewPager in my MainActivity and i am loading contents into it, which is working completely fine, but when i am setting onClickListener on the button to take the screenshot of that particular page, the screenshot is getting captured but of the next page, i have done debugging of the code but i am not able to find the exact reason for this. Here i am attaching the codes for the reference. Can somebody check where i am doing wrong?
I have tried searching the issue on this platform but none of them seems to have the solution to my problem.

I am unable to take the screenshot of the current viewpager item.
As @MikeM. suggested in the comment
Well, there are several different ways to do this. Assuming articleShareBtn is in each individual page, probably the simplest would be to articleShareBtn.setTag(rootView) after the rootView = ... line, then change your method to private Bitmap takeScreenshot(View root) { root.setDrawingCacheEnabled(true); ... }, and inside the onClick(), you would call it like Bitmap screenshotBitmap = takeScreenshot((View) view.getTag());. Follow me? Otherwise, you could keep a Map all the page Views, and use the current index to get the right one. There's a few other ways, too, if necessary.
I got it working. My updated Adapter code is
