viewpager2上下滑动时极易触发左右滑动

viewpager2 + tablayout 上下滑动时极易触发左右滑动

解决方式:

try {
    final Field recyclerViewField = ViewPager2.class.getDeclaredField("mRecyclerView");
    recyclerViewField.setAccessible(true);
    final RecyclerView recyclerView = (RecyclerView) recyclerViewField.get(viewPager);
    final Field touchSlopField = RecyclerView.class.getDeclaredField("mTouchSlop");
    touchSlopField.setAccessible(true);
    final int touchSlop = (int) touchSlopField.get(recyclerView);
    touchSlopField.set(recyclerView, touchSlop * 6);//6 is empirical value
} catch (Exception ignore) {
}
