android - 无法访问 PercentRelativeLayout

Question

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

感谢您的帮助。聊天

我已经使用 Android Tools 24.4.1 将 SDK Manager 更新到 Android 6.0 (API 23)，并安装了 Android Support Lib 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

关键错误是: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，所以如果我可以改进它，请告诉我。

再次感谢。

主.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:

不确定你是否可以让它与 ant 一起工作。

您可以尝试切换到 Gradle，然后您需要将以下依赖项添加到应用程序 build.gradle 文件中:

“编译‘com.android.support:percent:23.1.2’”
