What do you mean by output? This is just an Android XML Layout file. It doesn't generate any text output that I can post.
The only thing that I could post is a screenshot/video of what this does. But to be honest, I'm not 100% sure that I even have a project laying around that uses this piece of code (I kind forgot about it). But if that's want you need I can make a quick search to see if I can find anything.

Also, if it helps, I think that this snippet was taken from here: https://github.com/takahirom/webview-in-coordinatorlayout
More specifically the activity_scrolling.xml file in this folder: https://github.com/takahirom/webview-in-coordinatorlayout/tree/master/app/src/main/res/layout

And as you can see they have a GIF that shows the effect: https://cloud.githubusercontent.com/assets/1386930/13979570/b7235d0a-f11c-11e5-80e0-5ab6faa683e2.gif

Output means the screenshot of the emulator after running this piece of code...
Any way Thank you,I understood it.
Can you tell me how to get the fragment as a tabbed activity in a tabbed activity ?
