尝试使用新的支持设计库。在我的布局中,我希望ToolBar保持在屏幕的顶部,但是当用户向下滚动时,TabLayout会离开屏幕。但看起来ViewPager位于AppBarLayout下面。我用这篇博文作为参考 https://medium.com/ribot-labs/exploring-the-new-android-design-support-library-b7cda56d2c32

这是包含回收者视图的ViewPager保留Fragments内的布局

不要忘记在viewpager中设置它:

app:layout_behavior="@string/appbar_scrolling_view_behavior"
