How to disable or enable viewpager swiping in android

Question

What i am trying to do  I am trying to Enable disable swiping in pager programatically when the program is running   Ex  When on the flow if i check for a condition and if it returns true enable swiping  and if condition returns false disable swiping     Solution i am using is this one  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        Then select this instead of the builtin viewpager in XML   lt mypackage CustomViewPager  android id    id myViewPager   android layout height  match parent   android layout width  match parent    gt    You just need to call the  setPagingEnabled  method with  false  and users won t be able to swipe to paginate     Problem with above methodology  i cannot set the property on the flow  I e      I either can enable swiping or disable swiping  But i cannot do this based on condition    Question    Can i achieve my goal in some-other way  if so what is it   Or is this not possible

This worked for me      ViewPager OnPageChangeListener onPageChangeListener   new ViewPager OnPageChangeListener             public void onPageScrolled int position  float positionOffset  int positionOffsetPixels                   disable swipe             if  swipeEnabled                    if  viewPager getAdapter   getCount   gt 1                        viewPager setCurrentItem 1                       viewPager setCurrentItem 0                                                     public void onPageScrollStateChanged int state             public void onPageSelected int position                viewPager addOnPageChangeListener onPageChangeListener

I found another solution that worked for me follow this link  https   stackoverflow com a 42687397 4559365  It basically overrides the method canScrollHorizontally to disable swiping by finger  Howsoever setCurrentItem still works

In my case  the simplified solution worked fine  The override method must be in your custom viewpager adapter to override TouchEvent listeners and make em freeze    Override public boolean onTouchEvent MotionEvent event        return this enabled  amp  amp  super onTouchEvent event        Override public boolean onInterceptTouchEvent MotionEvent event        return this enabled  amp  amp  super onInterceptTouchEvent event

In your custom view pager adapter  override those methods in ViewPager    Override public boolean onInterceptTouchEvent MotionEvent event           Never allow swiping to switch between pages     return false      Override public boolean onTouchEvent MotionEvent event           Never allow swiping to switch between pages     return false      And to enable  just return each super method   super onInterceptTouchEvent event  and super onTouchEvent event

If you want to extend it just because you need Not-Swipeable behaviour  you dont need to do it  ViewPager2 provides nice property called   isUserInputEnabled

Best solution for me   -First  you create a class like this   public class CustomViewPager extends ViewPager     private Boolean disable   false    public CustomViewPager Context context          super context         public CustomViewPager Context context  AttributeSet attrs         super context attrs          Override   public boolean onInterceptTouchEvent MotionEvent event         return  disable  amp  amp  super onInterceptTouchEvent event           Override   public boolean onTouchEvent MotionEvent event         return  disable  amp  amp  super onTouchEvent event          public void disableScroll Boolean disable           When disable   true not work the scroll and when disble   false work the scroll       this disable   disable          -Then change this in your layout  lt android support v4 view ViewPager for this lt com mypackage CustomViewPager  -Finally  you can disable it view pager disableScroll true   or enable it  view pager disableScroll false    I hope that this help you
