在具有非静态片段的布局上有效地使用布局编辑器 [英] Use layout editor effectively on layouts with non-static fragments

问题描述

所有的Android开发工具都非常出色，尤其是在版本21之前，图形布局编辑器是一个功能强大的工具，可以对每个配置和区域设置的片段进行视图控制。我知道典型的活动的布局XML将包含静态片段标签，其中嵌入了布局编辑器的信息，例如 tools：layout =@ layout / book_collection_view_window_list。

With all the Android development tools greatness, especially as of version 21, the graphical layout editor is a powerful tool to have visual control over a layout with fragments for every configuration and locale. I'm aware that a typical Activity's layout XML will contain static fragment tags with info embedded for the layout editor, for example tools:layout="@layout/book_collection_view_window_list".

然而，因为我需要替换片段在我的窗口动态，我不能使用静态片段标签，而是需要提供容器，如 FrameLayout ，我可以在 replace（）中引用它。有什么像工具：布局或工具：上下文我可以在这个容器上使用，所以在布局编辑器中有不仅仅是黑色空洞，所以我可以利用它会给我的设计和验证功能。

However, because I need to replace the Fragments in my window dynamically, I cannot use the static fragment tags, and instead need to provide containers, such as FrameLayout, to which I can refer in replace(). Is there something like tools:layout or tools:context I can use on this container so in the layout editor there is more than just black emptyness, and so I can leverage the design and verification features it would give me?

推荐答案

至 FrameLayout的文档 ，就像您可以在 FrameLayout 标签上使用的属性在ViewGroup的前台放置一个可绘制的。

It looks, according to the documentation for FrameLayout, like there is an attribute you can use on the FrameLayout tag to put a drawable in the foreground of the ViewGroup.

您可以在设置视图时使用它来查看FrameLayout。我经常只是放一个颜色，所以我可以看到它是相对于背景和其他查看 s。

You could use this to see the FrameLayout whilst you are setting up your view. I often just put a colour in so I can see where it is relative to the background and other Views.
