How goto to specific vertical ittem

[leoperezdev]

Hello Julio is an interesting library. There is way to go to a certain position within the verticalPagers. For example I have a button that when pressed brings me to the last position of that verticalPager. It would like setCurrentItem method (int position) of ViewPager android. regards...

First I want to say thank you very match to Julio Gomez for this excellent code , you saved my day Bro.

Dear leoperezdev , To solve this issue you have to change the method : InstantiateItem(final ViewGroup container ,int position) in DoubleViewPagerAdapter.java.

This is what I did and It's perfectly working :

@OverRide

public Object instantiateItem(final ViewGroup container, int position) {

    VerticalViewPager childVP = new VerticalViewPager(mContext);

    childVP.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

    childVP.setAdapter(mAdapters.get(position));

    childVP.setOnPageChangeListener(new VerticalViewPager.OnPageChangeListener() {

        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {
            ((MainActivity)mContext).changeVerticalView(position);
        }

        @Override
        public void onPageScrollStateChanged(int state) {

        }
    });
    container.addView(childVP);
    return childVP;
}
