Android SlidingTableout在更改选项卡时平滑过渡/动画不会'；不能在碎片中工作

我正在使用谷歌的Slidengtablayout类。我的问题是，在我使用标签的活动中，在更改标签时有一个平稳的过渡。但是，如果我在片段中切换这些相同的选项卡，则不会发生相同的情况（.问题可能是什么

在我的Fragment类中，我使用此代码初始化SlidingTab

SlidingTabLayout slidingTabLayout = (SlidingTabLayout) view.findViewById(R.id.sliding_tabs);
        slidingTabLayout.setCustomTabView(R.layout.tab_layout, R.id.tab_layout_icon);
        slidingTabLayout.setSelectedIndicatorColors(getResources().getColor(R.color.mycolor));
        slidingTabLayout.setDistributeEvenly(true);
        slidingTabLayout.setViewPager(mPager);

这是我的幻灯片展示课
