将支持库布局属性提取为样式 [英] Extract Support Library layout attributes into styles

问题描述

我正在提取支持库GridLayout中的视图的样式.

I am extracting styles for views which are inside Support Library's GridLayout.

因此，我拥有"android"命名空间中的两个属性，例如android:layout_marginLeft="8dp"和应用"中的属性( http://schemas.android.com/apk/res-auto )一个，例如app:layout_columnSpan="2".

Therefore, I have both attributes from the "android" namespace, e.g. android:layout_marginLeft="8dp" and attributes from the "app" (http://schemas.android.com/apk/res-auto) one, e.g. app:layout_columnSpan="2".

首先，当我尝试将属性提取为样式时，Android Studio无法识别应用"中的属性.其次，手动将它们提取到styles.xml中似乎不会对实际布局产生任何影响.因此，是否有可能将支持库属性提取为单独的样式，以及如何提取?

First, Android Studio doesn't recognize the attributes from "app" when I try to extract the attributes as a style. Second, it doesn't seem that extracting them into styles.xml manually brings any effect to the actual layout. So, is it possible to extract the Support Library attributes as a separate style, and how?

推荐答案

我找到了一个类似问题的答案 .相同的解决方案对我有用.

I have found this answer to a similar question. The same solution worked for me.

只需为非"android"属性省略名称空间前缀:

Just leave out the namespace prefix for the non-"android" attributes:

app:layout_columnSpan="2"变为

<item name="layout_columnSpan">2</item>样式，不

<item name="app:layout_columnSpan">2</item>
