How to programmatically show next view in ViewPager?

AndroidAndroid Viewpager

Android Problem Overview

I created a ViewPager and everything is working fine, however I want to have a previous next button outside of ViewPager which can be used to navigate inside ViewPager. How can I go to next Item on ViewPager without swiping manually?

Solution 1 - Android

As blessenm answered viewpager.setCurrentItem(int index) is the way to go.

Solution 2 - Android

A complete implementation just for completeness:

public void MoveNext(View view) {
    //it doesn't matter if you're already in the last item
    pager.setCurrentItem(pager.getCurrentItem() + 1);
}

public void MovePrevious(View view) {
    //it doesn't matter if you're already in the first item
    pager.setCurrentItem(pager.getCurrentItem() - 1);
}

Solution 3 - Android

Easiest way is:

nextButton.setOnClickListener { pager.arrowScroll(View.FOCUS_RIGHT) }
prevButton.setOnClickListener { pager.arrowScroll(View.FOCUS_LEFT) }
