A simple solution is to create your own subclass of ViewPager that has a private boolean flag  isPagingEnabled  Then override the onTouchEvent and onInterceptTouchEvent methods  If isPagingEnabled equals true invoke the super method  otherwise return   public class CustomViewPager extends ViewPager        private boolean isPagingEnabled   true       public CustomViewPager Context context            super context              public CustomViewPager Context context  AttributeSet attrs            super context  attrs               Override     public boolean onTouchEvent MotionEvent event            return this isPagingEnabled  amp  amp  super onTouchEvent event               Override     public boolean onInterceptTouchEvent MotionEvent event            return this isPagingEnabled  amp  amp  super onInterceptTouchEvent event              public void setPagingEnabled boolean b            this isPagingEnabled   b            Then in your Layout XML file replace any  lt com android support V4 ViewPager gt  tags with  lt com yourpackage CustomViewPager gt  tags   This code was adapted from this blog post

There is an easy fix for this one   When you want to disable the viewpager scrolling then   mViewPager setOnTouchListener new OnTouchListener         public boolean onTouch View arg0  MotionEvent arg1          return true              And when you want to re-enable it then   mViewPager setOnTouchListener null     That will do the trick

The answer of slayton works fine   If you want to stop swiping like a monkey you can override a OnPageChangeListener with    Override public void onPageScrollStateChanged final int state             switch  state                 case ViewPager SCROLL STATE SETTLING                   mPager setPagingEnabled false                    break               case ViewPager SCROLL STATE IDLE                   mPager setPagingEnabled true                    break                      So you can only swipe side by side

The best solution that worked for me is   public class DeactivatedViewPager extends ViewPager        public DeactivatedViewPager  Context context            super context              public DeactivatedViewPager  Context context  AttributeSet attrs            super context  attrs               Override     public boolean canScrollHorizontally int direction            return false            After this the scroll will be disabled by touch and then you can still use setCurrentItem method to change page

I created a Kotlin version based on converting this answer from Java  https   stackoverflow com a 13437997 8023278 There is no built in way to disable swiping between pages of a ViewPager  what s required is an extension of ViewPager that overrides onTouchEvent and onInterceptTouchEvent to prevent the swiping action  To make it more generalised we can add a method setSwipePagingEnabled to enable disable swiping between pages  class SwipeLockableViewPager context  Context  attrs  AttributeSet   ViewPager context  attrs        private var swipeEnabled   false      override fun onTouchEvent event  MotionEvent   Boolean           return when  swipeEnabled                true - gt  super onTouchEvent event              false - gt  false                      override fun onInterceptTouchEvent event  MotionEvent   Boolean           return when  swipeEnabled                true - gt  super onInterceptTouchEvent event              false - gt  false                      fun setSwipePagingEnabled swipeEnabled  Boolean            this swipeEnabled   swipeEnabled          Then in our layout xml we use our new SwipeLockableViewPager instead of the standard ViewPager  lt mypackage SwipeLockableViewPager          android id  quot   id myViewPager quot           android layout height  quot match parent quot           android layout width  quot match parent quot    gt   Now in our activity fragment we can call myViewPager setSwipePagingEnabled false  and users won t be able to swipe between pages  UPDATE As of 2020 we now have ViewPager2  If you migrate to ViewPager2 there is a built in method to disable swiping  myViewPager2 isUserInputEnabled   false

How about this    I used CustomViewPager  and next  override scrollTo method I checked the movement when doing a lot of small swipes  it doesn t scroll to other pages   public class CustomViewPager extends ViewPager        private boolean enabled       public CustomViewPager Context context  AttributeSet attrs            super context  attrs           this enabled   true              Override     public boolean onTouchEvent MotionEvent event            if  this enabled                return super onTouchEvent event                      return false              Override     public boolean onInterceptTouchEvent MotionEvent event            if  this enabled                return super onInterceptTouchEvent event                      return false             public void setPagingEnabled boolean enabled            this enabled   enabled               Override     public void scrollTo int x  int y           if enabled              super scrollTo x  y

I suggest another way to solve to this problem  The idea is wrapping your viewPager by a scrollView  so that when this scrollView is non-scrollable  your viewPager is non-scrollable too   Here is my XML layout            lt HorizontalScrollView             android id    id horizontalScrollView              android layout width  match parent              android layout height  match parent              android fillViewport  true   gt                lt android support v4 view ViewPager                 android id    id viewPager                  android layout width  wrap content                  android layout height  match parent    gt            lt  HorizontalScrollView gt    No code needed   Works fine for me
