浓缩咖啡 - 单击gridview内的图像

Question

我有一个视图层次结构如下:

GridView{id=2131362110, res-name=item_list_grid, 
|
+----->RelativeLayout{id=2131362124, res-name=item_image_thumb_layout
|
+------------->ImageView{id=2131362125, res-name=item_image
|
+----->RelativeLayout{id=2131362124, res-name=item_image_thumb_layout
|
+------------->ImageView{id=2131362125, res-name=item_image
|
+------>RelativeLayout{id=2131362124, res-name=item_image_thumb_layout
|
+------------->ImageView{id=2131362125, res-name=item_image
|
GridView{id=2131362110, res-name=item_list_grid, ...etc

我想点击其中一个带有id = item_image的ImageView.

我不能像atPosition(x)一样使用onView,所以我使用了onData.我尝试了所有这些:

onData(allOf(anything(),withId(R.id.item_image))).atPosition(0).perform(click());

onData(anything()).atPosition(0).perform(click());

onData(allOf(atPosition(0),withId(R.id.item_image))).perform(click());

但所有结果都是

android.support.test.espresso.AmbiguousViewMatcherException: 'is assignable from class: class android.widget.AdapterView' matches multiple views in the hierarchy.

有什么建议吗？谢谢!

您的错误消息告诉您在您的活动中有多个视图,这些视图扩展了表单,AdapterView因此您有另一个ListView或GridView在您的布局中.

您可以选择AdapterView数据层.所以选择这个AdapterView类型的项目ItemModel

onData(is(instanceOf(ItemModel.class))).atPosition(0)
    .onChildView(withId(R.id.item_image)).perform(click());

或者您可以AdapterView按ID 选择特定的

onData(anything()).inAdapterView(withId(R.id.my_grid_view)).atPosition(0).
            onChildView(withId(R.id.item_image)).perform(click());
