android – 使用Robolectric测试ActionBarActivity时出错

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：

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

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
