我正在使用Robolectric来测试我的应用程序中的活动.该活动扩展了ActionBarActivity.当我测试活动时,我得到错误：“IllegalStateException：你需要在这个活动中使用Theme.AppCompat主题(或后代).”
我的测试环境是：Android Studio 0.8.6,Robolectric 2.4-SNAPSHOT,support-v4库版本20.0,appcompat-v7版本20.0.
现在为班级.活动 ：
public class FilterActivity extends ActionBarActivity
测试类：
@Config(emulateSdk = 18,manifest = "src/main/AndroidManifest.xml")
@RunWith(RobolectricTestRunner.class)
public class FilterActivityTest
{
private FilterActivity activity;
@Before
public void setUp() throws Exception
{
activity = Robolectric.buildActivity(FilterActivity.class).create().get();
}
@After
public void tearDown() throws Exception
{
activity.finish();
}
@Test
public void testOnCreate()
{
}
}
我从values文件夹中的styles.xml：
<style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar"> </style>
堆栈跟踪：

谢谢您的帮助.
解决方法
我有同样的问题,我相信这是由使用@ style / Theme.AppCompat.Light.DarkActionBar vs Theme.AppCompat.Light.DarkActionBar引起的.
<style name="Theme.MyApp" parent="Base.Theme.MyApp">
</style>
<style name="Base.Theme.MyApp" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">@color/charcoal_gray</item>
<item name="colorPrimaryDark">@color/black</item>
<item name="colorAccent">@color/white</item>
<item name="android:windowBackground">@color/black</item>
</style>
另外,可能值得一提的是,在使用较新版本的支持库时,建议将ActionBarActivity切换为AppCompatActivity,因为前者现已弃用.
如果您使用较旧的目标sdk,这可能适用于您：ActionBarCompat: java.lang.IllegalStateException: You need to use a Theme.AppCompat
