public boolean dispatchTouchEvent(MotionEvent ev) {
  if(!onInterceptTouchEvent()){
    for(View child : children){
      if(child.dispatchTouchEvent(ev))
        return true;
    }
  }
  return super.dispatchTouchEvent(ev);
}

代码示例来源：origin: alexvasilkov/GestureViews

@SuppressLint("ClickableViewAccessibility") // Not needed for ViewPager
  @Override
  public boolean onTouch(View view, @NonNull MotionEvent event) {
    // ViewPager will steal touch events during settling regardless of
    // requestDisallowInterceptTouchEvent. We will prevent it here.
    if (!isTouchInProgress && event.getActionMasked() == MotionEvent.ACTION_DOWN) {
      isTouchInProgress = true;
      // Now ViewPager is in drag mode, so it should not intercept DOWN event
      view.dispatchTouchEvent(event);
      isTouchInProgress = false;
      return true;
    }
    // User can touch outside of child view, so we will not have a chance to settle
    // ViewPager. If so, this listener should be called and we will be able to settle
    // ViewPager manually.
    settleViewPagerIfFinished((ViewPager) view, event);
    return true; // We should skip view pager touches to prevent some subtle bugs
  }
};
