我用navigation drawer实现了我的导航应用程序,但其中一个条目用两个选项卡打开片段。
我实现的选项卡是“fragmenttabhost”,因为Roman Nurik不建议将“viewPager”与“NavigationDrawer”一起使用。

一切正常我的问题是,fragmenttabhost是否可以在选项卡之间实现水平滑动?
附加代码:

可以用fragmenttabhost实现水平滑动吗?
我搜索了一些信息,但都说是为了更好地使用viewpager。
最佳答案
所以他完整的回答是
不应该使用带有操作栏选项卡的导航抽屉。如果你是
针对类似于google play music的用户界面,您应该
手动实现制表符(注意在平板电脑上的外观
不希望平板电脑上有全宽标签栏)。还要确保检查
在今年的安卓应用程序设计会议上
google i/o,用于各种界面的详细运行
可用于公开应用程序层次结构的模式。
所以基本上他建议重新考虑用户界面…我想这是不推荐的,因为拉出抽屉和在标签之间滑动实际上是用同样的手势。
编辑:如果你真的想手动刷tabhost,我想唯一的方法是使用flipper和手势检测器(实现gesturelister)。这是您需要实现的一点代码,但我希望this example of Swipe Action and ViewFlipper in Android可以帮您一点忙。;)
edit2:还有一个例子(就像作者知道我们昨天在谈论它一样;)
