main.xml中

Question

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

感谢您的帮助。 chatt

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 Support Lib的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：没有为属性＆＃39; layout_marginTopPercent＆＃39;找到资源标识符。在包裹＆＃39; com.Chatterton.Peter.ChessClock＆＃39;

这是我在这里发表的第一篇文章，所以如果我能对其进行改进，请告诉我。

再次感谢。

main.xml中

<?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：

不确定你是否可以使用ant。

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

“编译'com.android.support:percent:23.1.2'”

无法访问PercentRelativeLayout
