使用Robolectric测试ActionBarActivity时出错

Question

我正在使用Robolectric来测试我的应用程序中的活动。该Activity继承自ActionBarActivity。当我测试这个活动时，我会遇到以下错误：

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

我的测试环境如下:

- Android Studio 0.8.6 - Robolectric 2.4-SNAPSHOT - support-v4库版本20.0 - appcompat-v7版本20.0

现在来看这些类。这个活动：

public class FilterActivity extends ActionBarActivity

测试类如下：

@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()
    {

    }
}

我的styles.xml文件位于values文件夹中：

<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.

你的AndroidManifest中application元素的android:theme属性指向什么？ - iamreptar

Answer 1

我遇到了同样的问题，我相信这是由于使用 @style/Theme.AppCompat.Light.DarkActionBar 而不是 Theme.AppCompat.Light.DarkActionBar 导致的。

<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>

此外，可能值得一提的是，当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。

如果您正在使用较旧的目标 SDK，则可能适用于您： ActionBarCompat:java.lang.IllegalStateException：您需要使用Theme.AppCompat
