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

<mypackage.CustomViewPager 
android:id="@+id/myViewPager" 
android:layout_height="match_parent" 
android:layout_width="match_parent" />

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 ?

Would not it be possible to set the property on the flow with DataBinding ? — oldergod, Jan 25 '17 at 05:00

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 && super.onInterceptTouchEvent(event);
  }

  @Override
  public boolean onTouchEvent(MotionEvent event) {
     return !disable && 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:<android.support.v4.view.ViewPager for this<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 :)

Also don't forget to call **viewPager.invalidate()** method after calling disable scrolling method, because of that it instantly disable swipe over. – Ritesh Adulkar Dec 17 '18 at 05:45
With this solution the views inside ViewPager will not receive any input if `disable == true`. Overriding `onInterceptTouchEvent()` is not the correct solution. – Alex Semeniuk Jul 16 '19 at 14:19
instead of Boolean I'd rather use boolean here. – hgoebl Nov 09 '19 at 11:13
Thanks. Your answer helped me to improve a working feature. – AndyN Dec 05 '19 at 07:27
For Viewpager2 you don't need custom class you can simply disable scroll by using myViewPager2.setUserInputEnabled(false); – Khizar Hayat Aug 21 '21 at 11:04

Disable swipe progmatically by-

    final View touchView = findViewById(R.id.Pager); 
    touchView.setOnTouchListener(new View.OnTouchListener() 
    {         
        @Override
        public boolean onTouch(View v, MotionEvent event)
        { 
           return true; 
        }
     });

and use this to swipe manually

touchView.setCurrentItem(int index);

This still lets the viewpager to be partially swiped (like 1%) before it stops. It looks ugly. – IgorGanapolsky Sep 28 '15 at 20:23

His solution works, it is just incomplete. You should also override onInterceptTouchEvent(MotionEvent event) too. This will give you the look you desire without the 1% – portfoliobuilder Oct 03 '15 at 01:20

Unable to overide that method – Animesh Mangla Dec 13 '15 at 08:41
it works but when it enabled , swiping is very bad and slow – faeze saghafi Sep 03 '16 at 08:37
It not works, try to swipe your view pager repeatedly, and you can see your another view shown !!. you have to set onInterceptTouchEvent too. – FarshidABZ Oct 13 '16 at 20:54

this is absulutally wrong solution, why so many stars. It indeed looks ugly, with swipe of 1%. Probably, we should extend viewpager, and override onInterceptTouchEvent – Anton Kizema Apr 21 '17 at 15:45
If you override `onInterceptTouchEvent()` (return true, for example), the views inside ViewPager will not receive input. Which is __not__ what you want in most cases. – Alex Semeniuk Jul 16 '19 at 14:16

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).

For disabling swiping

mViewPager.beginFakeDrag();

For enable swiping

if (mViewPager.isFakeDragging()) mViewPager.endFakeDrag();

I try to use this solution, but it'll throw NullPointerException when calling endFakeDrag. – Mia Mar 19 '19 at 02:20
try to use a condition like. if (mViewPager.isFakeDragging()) mViewPager.endFakeDrag(); – Sanjay Bhalani Mar 19 '19 at 10:46
This doesn't stop swiping. It just makes it ugly – Harsha Bhadra Jul 22 '22 at 05:59

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

To disable swiping in viewpager2 use

viewPager2.setUserInputEnabled(false);

To enable swiping in viewpager2 Use

viewPager2.setUserInputEnabled(true);

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 && super.onTouchEvent(event);

}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    return this.enabled && super.onInterceptTouchEvent(event);

}

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.

The `canScrollHorizontally()` method has no effect in current scenario. It is not even called when swipe happens. – Alex Semeniuk Jul 16 '19 at 14:23

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()>1) {
                    viewPager.setCurrentItem(1);
                    viewPager.setCurrentItem(0);
                }
            }
        }
        public void onPageScrollStateChanged(int state) {}
        public void onPageSelected(int position) {}
    };
    viewPager.addOnPageChangeListener(onPageChangeListener);
