In your code on button click write this line,

startActivity(new Intent(CurrentActivity Name, TargetActivity.class).putExtras(tempBundle)

tempBundle is a Bundle argument for identify which position of the pager you want to display at current.

Then in your target Activity get the Bundle information, and set your ViewPager.

viewPager.setCurrentItem(0); //You can set your Bundle information 0 or 1 or 3

That time your ViewPager can set according to given position.

We have Two ways

  • Use Static Methods OR
  • Use interface to communicate between activities and fragments also

Communication through Interface
