这就是我的测试方法的样子：
@RunWith(RobolectricTestRunner.class)
public class TestMyApplication{
private About aboutActivity;
@Test
public void AboutActivityTest() throws Exception{
aboutActivity = new About();
aboutActivity.onCreate(null);
TextView aboutInfo = (TextView) sobreActivity.findViewById(R.id.text_version);
assertThat(sobreInfo.getText().toString(), equalTo("My Application v1.0"));
}
}
关于Activity.onCreate(null); 的行 运行此测试时引发以下异常

只有当我从 about.xml 布局文件中评论以下视图（自定义 RelativeLayout）时，我的测试才能完美运行：
<br.com.componente.ActionBar
android:id="@+id/actionbar"
style="@style/ActionBar"
android:layout_alignParentTop="true"/>
我无法从 xml 文件中删除此视图，因为我也需要对其进行测试。有谁知道如何解决它？
谢谢
