android – 带有ActionBarActivity的ActivityUnitTestCase的NameNotFoundException

但是,如果测试中的活动是ActionBaractivity,则会出现以下异常：

我的测试类如下所示：

public class MyActivityTest extends ActivityUnitTestCase<MyActivity> {

    ...

    public MyActivitytest() {
        super(MyActivity.class);
    }

    private Context context;

    private TestBaseApplication application;

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        context = new ContextThemeWrapper( getInstrumentation().getTargetContext(),R.style.Theme_AppCompat){
            @Override
            public Context getApplicationContext() {
                return application;
            }
        };
        application = new TestBaseApplication( context);
        setApplication(application);

        ...
    }

    public void test() throws InterruptedException {
        setActivityContext( context);
        Intent intent = new Intent( context,MyActivity.class);
        startActivity(intent,null,null);
        ...
    }
}

该活动出现在AndroidManifest中,如下所示：

<activity
            android:name=".view.activity.MyActivity"
            android:icon="@drawable/actionbar_logo"
            android:screenorientation="portrait"
            android:parentActivityName="mypackage.ParentActivity">
            <Meta-data android:name="android.support.PARENT_ACTIVITY"
                android:value="mypackage.ParentActivity"/>
        </activity>

经过一些故障排除后,我尝试在上面的链接上运行示例,它工作正常,即使我更改活动以扩展ActionBaractivity.

由于我无法找到问题的原因,我也玩了清单,build.gradle等.现在,我只是坚持这个,我想不出别的什么.

This post也可能与问题有关,但也没有任何评论.并且this post似乎也有类似的问题,但那里的解决方案不起作用,因为我不希望真正的应用程序与活动一起启动.

编辑：

我创建了一个简单的单独项目,以便隔离问题.

首先,我为一个扩展ActionBaractivity的Activity编写了一个ActivityUnitTestCase.它工作正常.

在那之后,我尝试添加更多的活动,使它们成为彼此的父级.(因此它看起来像我的实际项目).这也很好.

最后,我添加了更多ActivityUnitTestCase类,其中包含与我的实际项目不同的活动,所有活动都扩展了ActionBaractivity,并为所有活动设置了相同的设置,并在两个设备上运行测试,一个是模拟器(Genymotion),另一个是我的物理设备. (Nexus 4)

测试都在模拟器上给出了NameNotFoundException.除了其中一项测试外,所有测试都在物理设备上传递,这让我更加困惑.
