所以这可能是这个问题的重复：Testing custom Views with Robolectric 但是既然那个人没有接受答案，我会用自己的代码示例再次提问。 我使用Robolectric 2.3在一个项目上运行单元测试，该项目使用一个名为＆＃34; here_now.xml＆＃34;的文件中定义的自定义视图。为：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:weightSum="1">
<me.ambient.meetup.swiper.SwipeListView
xmlns:swipe="http://schemas.android.com/apk/res-auto"
android:id="@+id/nearbyPeopleList"
android:listSelector="#00000000"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
swipe:swipeFrontView="@+id/user_profile_layout"
swipe:swipeBackView="@+id/user_profile_bg"
swipe:swipeDrawableChecked="@drawable/plus"
swipe:swipeDrawableUnchecked="@drawable/minus"
swipe:swipeCloseAllItemsWhenMoveList="true"
swipe:swipeMode="both"/>
</LinearLayout>
那个＆＃39; SwipeListView＆＃39;是一个自定义视图，它具有这些自定义XML属性。现在，这在应用程序上编译并运行正常。但是当运行涉及实例化该视图的父活动的Robolectric测试时，我遇到了通胀错误：

我还将我的Robolectric测试放在Scala FWIW中：
@Config(manifest = "./src/main/AndroidManifest.xml")
@RunWith(classOf[RobolectricTestRunner])
class HereNowActivityTest extends Asserter with ThreadManipulator {
@Test
def testEditProfileMenuButton(): Unit = {
val activity: HereNowActivity = Robolectric.buildActivity(classOf[HereNowActivity]).create().start().get()
val editProfileItem = activity.findViewById(R.id.action_edit_profile).asInstanceOf[MenuItem]
activity.onOptionsItemSelected(editProfileItem)
val shadowActivity = Robolectric.shadowOf(activity)
val startedIntent = shadowActivity.getNextStartedActivity()
val shadowIntent = Robolectric.shadowOf(startedIntent)
assertEquals(shadowIntent.getComponent().getClassName(), "me.ambient.meetup.EditProfileActivity")
}
}
有没有人知道为什么我在运行Robolectric测试时无法充气自定义视图，以及无法设置任何自定义属性？
