我正在使用自己的属性测试（工作）复合控件（也称为自定义视图）并尝试使用RoboAttributeSet来配置视图的属性。我还没有找到关于此功能的全面示例或文档，以及在使用构造函数时我的属性创建使用的值。我确定它很容易解决，但我无法找到它。
我已经审核了这些问题：RoboAttributeSet，Custom view inflation error和Shadowing custom views ......以及其他互联网无济于事。
注意：我的完整软件包名称为：com.colabug.local.food
注意：我使用的文件名不是attrs.xml，如Android教程中所述。
CoverViewTest.java
public class CoverViewTest
{
private Activity activity;
private CoverView coverView;
// Data
private Delicacy data;
// UI
private RatingBar ratingBar;
@Before
public void setUp() throws Exception
{
activity = createActivity();
coverView = getCoverView( activity, null );
data = createDummyData( false, 2, false );
coverView.setData( data );
ratingBar = (RatingBar) coverView.findViewById( R.id.cover_view_rating_bar );
}
private CoverView getCoverView( Activity activity,
RoboAttributeSet attributeSet )
{
CoverView view;
view = new CoverView(Robolectric.application.getApplicationContext(), attributeSet);
// view = (CoverView) LayoutInflater.from( activity )
// .inflate( R.layout.cover_view,
// new CoverView( activity ),
// true );
return view;
}
@Test
public void showRatingBarAttribute_shouldShowRatingBar() throws Exception
{
ArrayList<Attribute> attributes = new ArrayList<Attribute>();
attributes.add( new Attribute( "com.colabug.local.food:cover_attrs/showRatingBar", String.valueOf( true ), "com.colabug.local.food") );
RoboAttributeSet attributeSet = new RoboAttributeSet( attributes,
Robolectric.application.getResources(),
CoverView.class );
CoverView view = getCoverView( activity, attributeSet );
view.setData( createDummyData( false, 2, false ) );
assertViewIsVisible( view.findViewById( R.id.cover_view_rating_bar ) );
}
}

答案 0 :(得分：3)
对于那些仍然想知道如何在版本3中配置的人：查看Roboelectric的样本。找我这么久就找到了。
答案 1 :(得分：0)
尽管命名文件cover_attrs.xml，但在那里声明的资源类型仍然是attr，看起来这就是Robolectric在抛出异常时试图强制实施的内容（{{3} }）。
您可以尝试将attributes.add来电中的属性更改为"com.colabug.local.food:attr/showRatingBar"并查看其是否有效吗？
