How to recognize the last page of viewpager and automatically redirect to first page when swiped












0















My title is my problem, I have 3 pages in a viewPager. How do I redirect to first page when I swipe on the last page in viewPager?



ViewPager.OnPageChangeListener viewPagerPageChangeListener = new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
int x = position;
Log.i("ON Possition",Integer.Tostring(x));
if(x == 3){
viewPager.setCurrentItem(x);
Log.i("ON last Possition",Integer.Tostring());
}
}

@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {

}

@Override
public void onPageScrollStateChanged(int arg0) {

}
};

          you can't move to first page smoothly from last page.



          read below code. we should fake item count.

          @Override

          if (tList != null && tList.size() > 1) {
          return tList.size() * MAX_PAGE; // simulate infinite by big number of products
          } else {
          return tList.size();
