$1 = std::vector of length 3, capacity 4 = {10, 20, 30}
To achieve above, you need to have gdb 7 (I tested it on gdb 7.01) and some python pretty-printer. Installation process of these is described on gdb wiki.

Prevent ViewPager from destroying off-screen views
...ify the number of offscreen pages to use, rather than the default which is 1.
In your case, you want to specify 2, so that when you are on the third page, the first one is not destroyed, and vice-versa.
