PercentRelativeLayout百分比值缺少XML资源类型? [英] Missing XML resource type for PercentRelativeLayout Percentage value?

问题描述

似乎发布了新的百分比支持库，但不允许在维度xml文件中引用百分比值.

It seems that the new Percent Support Library was released without allowing to reference a Percentage value in a dimension xml file.

也就是说，而不是:

 <android.support.percent.PercentRelativeLayout
         xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:app="http://schemas.android.com/apk/res-auto"
         android:layout_width="match_parent"
         android:layout_height="match_parent"/>
     <ImageView
         app:layout_widthPercent="50%"
         app:layout_heightPercent="50%"
         app:layout_marginTopPercent="25%"
         app:layout_marginLeftPercent="25%"/>
 </android.support.percent.PercentFrameLayout/>

能够编写类似的代码:

 <android.support.percent.PercentRelativeLayout
     xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:app="http://schemas.android.com/apk/res-auto"
     android:layout_width="match_parent"
     android:layout_height="match_parent"/>
 <ImageView
     app:layout_widthPercent="@percent/myWidthPercent"
     app:layout_heightPercent="@percent/my/HeightPercent"
     app:layout_marginTopPercent="@percent/myMarginTophPercent"
     app:layout_marginLeftPercent="@percent/myMarginLeftPercent"/>

其中myWidthPercent在资源文件中定义.

where myWidthPercent is defined in a resource files.

我错了吗(我想念另一个名字吗)还是我们可以发送给Google的功能请求?

Am i wrong (did i miss it with another name) or is it a feature request that we could send to google?

推荐答案

使用分数代替百分比

<resources>
    <fraction name="myWidthPercent">50%</fraction>
...
</resources>

并引用它

<ImageView
    app:layout_widthPercent="@fraction/myWidthPercent"
    app:layout_heightPercent="@fraction/my/HeightPercent"
    app:layout_marginTopPercent="@fraction/myMarginTophPercent"
    app:layout_marginLeftPercent="@fraction/myMarginLeftPercent"/>
