带有滑动标签的Android Navigationdrawer

我无法实现导航抽屉和滑动标签。 当我使用导航抽屉时，我点击一些项目，一个新的片段替换了我的项目中的FrameView（称为content_frame）。当我使用PageAdapter实现滑动选项卡时，问题变得明显。现在，当我单击导航抽屉并将新片段提交到content_frame时，它会与当前Tab重叠。 这是因为我使用content_frame替换Navigation抽屉中的片段，并使用pageadapter创建3个固定标签。有没有办法让它成为例如一个片段将取代当前的选项卡或选项卡只会动态加载到FrameLayout，如我的content_frame？它也有助于进一步发展。
