Answer 1

So I guess I found the solution by my self:

First of all: Pinterest indeed uses a ViewPager with a custom Page Transformer like @frozenkoi has mentioned in his answer. You can see the oversroll edge effect of the view pager in the pinterest app.

@Amit Gupta has pointed to library that let the activity slide. Its pretty the same concept like various Navigation drawers does and sets also the theme to translucent. They slide the layout. But thats not exactly what I was looking for, because it slides the top activity to the right and than simply calls finish(). But the underneath activity will not be animated in.

The solution is (and I guess this is was Tumblr does) to write your very own Animation with Animation Objects and animate it step by step. This can be done with ActivityOptions. In my opinion this will be the solution.
