Robolectric Issue with ProgressBar

问题

I keep getting a RuntimeException from Robolectric when it tries to invoke an onCreate for an activity that has a ProgressBar. I've localized the issue to this block in the layout xml file. As soon as I remove this and re-run the test, things work fine.

<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"/>

Here is the full stack trace:

I'm working of the github head (1.0-RC2) because I thought the ShadowProgressBar would help me out but it doesn't seem to have, but I might not be using it correctly.

I also thought the id or the style were causing the issue but removing them in the XML didn't stop the Exception.

Any help would be appreciated.

UPDATE

I changed the progress bar xml to this:

<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" />

And it worked.

回答1:

change

android:id="@+android:id/progress_large"

to

android:id="@+id/progress_large"
