method

in

androidx.viewpager.widget.ViewPager

@Override
public boolean onTouchEvent(MotionEvent event) {
  if (this.enabled) {
    return super.onTouchEvent(event);
  }

    viewPager.onTouchEvent(fixedEvent);
  } else {
    isViewPagerInterceptedScroll = viewPager.onInterceptTouchEvent(fixedEvent);
  }
  // If ViewPager intercepted touch it will settle itself automatically,
  // but if touch was not intercepted we should settle it manually
  if (!isViewPagerInterceptedScroll && hasViewPagerX()) {
    settleViewPagerIfFinished(viewPager, event);
  }
  // Hack: ViewPager has bug when endFakeDrag() does not work properly. But we need to ensure
  // ViewPager is not in fake drag mode after settleViewPagerIfFinished()
  try {
    if (viewPager != null && viewPager.isFakeDragging()) {
      viewPager.endFakeDrag();
    }
  } catch (Exception ignored) {
  }
