我想在win10下使用Ant的命令行项目中使用PercentRelativeLayout。我是Android的新手，但具有Java背景（作为程序员）。我也是蚂蚁的新手。

谢谢你的帮助。闲聊

我已使用Android Tools 24.4.1将SDK Manager更新为Android 6.0（API 23），并安装了Android支持库v23.2。

我有以下内容：

C:\Users\chatt\AppData\Local\Android\sdk1\extras\android\support\percent

和

C:\Users\chatt\AppData\Local\Android\sdk1\extras\android\support\v14\preference\libs

严重错误是：在包'com.Chatterton.Peter.ChessClock'中找不到属性'layout_marginTopPercent'的资源标识符

这是我在这里的第一篇文章，因此，如果我可以改进的话，请告诉我。

再次感谢。

main.xml

<?xml version="1.0" encoding="utf-8"?>
<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_marginTopPercent="25%"
          app:layout_marginLeftPercent="25%"
          app:layout_widthPercent="50%"
          app:layout_heightPercent="50%" />
</android.support.percent.PercentRelativeLayout>

编译结果：
