In my project I have used a viewpager with 3 pages in it. Now in the first page I have a next button. So first time when I am in first page, we should not allow swipe until next button is clicked. When next button is clicked we can come back to first page by swiping. So we should allow swipe from page 2 to page 1. Similarly i have a next button in page2. So there also first time when i am in page2, using swipe it should not allow to go to page 3. Only after clicking on next button in page2, then it will go to page3. From page 3 it should allow swipe to go to page 2 and page1. How can I achieve this. I am trying from past two weeks using some custom view pager classes available in internet tutorials but none of them worked for me as per the requirement.
My Code:
public class PagerFragment : Android.Support.V4.App.Fragment
{
public static ViewPager pager;
public override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your fragment here
}
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var view = inflater.Inflate(Resource.Layout.pager_layout, container, false);
pager = view.FindViewById<ViewPager>(Resource.Id.viewPager);
TabLayout tabLayout = view.FindViewById<TabLayout>(Resource.Id.tab_layout);
pager.Adapter = new PagerAdapter(ChildFragmentManager);
tabLayout.SetupWithViewPager(pager, true):
return view;
}
pagerlayout.axml:
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabBackground="@drawable/tab_selector"
app:tabIndicatorHeight="0dp" />
</LinearLayout>
</LinearLayout>
Please help me on this. Will be really thankful
