ProgressBar 的 Robolectric 问题

Question

当 Robolectric 尝试为具有 ProgressBar 的活动调用 onCreate 时，我不断收到 RuntimeException。我已将问题定位到布局 xml 文件中的此块。一旦我删除它并重新运行测试，一切就正常了。

<ProgressBar android:id="@+android:id/progress_large"
  style="?android:attr/progressBarStyleLarge"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_centerInParent="true"
  android:visibility="invisible"/>

这是完整的堆栈跟踪：

我正在使用 github head (1.0-RC2)，因为我认为 ShadowProgressBar 会帮助我，但它似乎没有，但我可能没有正确使用它。

我还认为 id 或样式导致了问题，但在 XML 中删除它们并没有阻止异常。

任何帮助将不胜感激。

更新

我将进度条 xml 更改为：

<ProgressBar 
  android:id="@+id/circle_progress_bar"
  style="@android:style/Widget.ProgressBar.Large.Inverse"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_centerInParent="true"
  android:visibility="invisible" />

并且它有效。
