TextView inside nested ViewGroup in the pager cannot be updated properly

[hrhktkbzyy]

I just modified Emil Sjölander's demo code. I add a RelativeLayout inside the page.xml. Inside this RelativeLayout, I added in a TextView, id is textViewQuizNo.

In the getView() of FlipAdapter, I set the position no to this TextView, the same as the original TextView(id is text) which is not inside a RelativeLayout, but directly inside the FrameLayout. When I run the code, the weird thing happened: The textViewQuizNo's text is 0,1,2,0,1,2,0,1,2... when I flip the page, while the text's text is 0, 1, 2, 3, 4, 5...

I dug into Emil's code for a while, and I found a solution, please refer the detailed explanation in StackOverflow: http://stackoverflow.com/questions/32194851/emil-sj%C3%B6landers-flipview-textview-inside-nested-viewgroup-in-the-pager-cannot
