Can you post your Activity code where you are implementing this fucntion? — Sanoop Surendran, Jun 24 '17 at 07:15
@Sanoop my activity have multiple fragment and i'm using `EventBus` for disable/enable view pager on parent activity by this code: `@Subscribe public void onEvent(EventChangeMainApplicationSwappableViewPagerStatus event) { AndroidUtilities.changeSwappableViewPagerStatus(viewPager, event.isStatus()); }` — tux-world, Jun 24 '17 at 07:55

For doing this you should make a subclass of viewpager like following and do it in onTouchEvent:

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.animation.DecelerateInterpolator;
import android.widget.Scroller;
import java.lang.reflect.Field;

public class NonSwipeableViewPager extends ViewPager {

    public NonSwipeableViewPager(Context context) {
        super(context);
        setMyScroller();
    }

public NonSwipeableViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
    setMyScroller();
}

@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;
}

//down one is added for smooth scrolling

private void setMyScroller() {
    try {
        Class<?> viewpager = ViewPager.class;
        Field scroller = viewpager.getDeclaredField("mScroller");
        scroller.setAccessible(true);
        scroller.set(this, new MyScroller(getContext()));
    } catch (Exception e) {
        e.printStackTrace();
    }
}

public class MyScroller extends Scroller {
    public MyScroller(Context context) {
        super(context, new DecelerateInterpolator());
    }

    @Override
    public void startScroll(int startX, int startY, int dx, int dy, int duration) {
        super.startScroll(startX, startY, dx, dy, 350 /*1 secs*/);
    }
}
}

using widget like with your code is not useful for my application, i'm trying to use java code to disable or enable that — tux-world, Jun 24 '17 at 07:01
