Question

问题2： 单击另一个选项卡时，选项卡栏无法还原到原始位置（选项卡1带有非回收查看）。它粘在顶部，直到它可以使用将它发送到顶部的标签2向后滚动

我使用的是可重复使用的代码，无需每次都重写App Bar和Navigation Drawer。

问题1详细信息： 当滚动回收者视图时，应用栏可以滚动，但是标签栏隐藏在应用栏后面，直到应用栏向上滚出屏幕（标签栏无法移动并保持在0 y坐标）

问题1（已修复）： 解决方案：移动线＆＃34; app：layout_behavior =＆＃34; @ string / appbar_scrolling_view_behavior＆＃34;从viewpager到framelayout
