And if I go to the next tab say 3rd tab then the method present in the 4th fragment gets called and so on. I don't understand this behavior.

问题 Is it possible to change color of selected tab on v4 ViewPager? I need to use v4 ViewPager, but I don't find any source to customize it. Just to clarify I need to change the blue color to another one: 回答1: This is the tab indicator. You can change its color by applying different styles.
