Android Nested ViewPager Disable Touch Event

Question

In my app, I have a ViewPager. In one of the pages, I have another ViewPager, in which I have disabled the swipe gestures through a custom ViewPager implementation:

public class NonSwipeableViewPager extends ViewPager {

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

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

    @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;
    }
}

This works well; the swipe gestures in the child ViewPager are disabled. However, the parent ViewPager cannot be swiped unless the swipe starts from the very edge of the screen. How can I make the child ViewPager ignore all touch events/pass them on to the parent view?

The answer turned out to be very simple!

public class NonSwipeableViewPager extends ViewPager {

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

    }

    @Override
    public boolean canScrollHorizontally(int direction) {
        return false;
    }

}
