为什么在布局XML中定义<shape>时会出现ClassNotFoundException？

Question

我试图绘制一个矩形,包括/layout/myactivity.xml:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
  <corners
      android:radius="2dp"
      android:topRightRadius="0dp"
      android:bottomRightRadius="0dp"
      android:bottomLeftRadius="0dp" />
  <stroke
      android:width="1dp"
      android:color="@android:color/white" />
</shape>

当我尝试运行项目时,我得到:

05-12 23:37:14.090: E/AndroidRuntime(541): Caused by: java.lang.ClassNotFoundException: android.view.shape

我错过了什么吗？

您的XML代码很好,位置就是问题.res/layout您可能希望将其保存在res/drawable特定的可绘制文件夹中,而不是将此文件放在您的文件夹中res/drawable-xhdpi.
