使用通过xml：
从Activity视图启动的片段 <fragment
android:id="@+id/listconversations"
android:contentDescription="my list fragment"
android:name="com.example.ui.MyListFragment"
android:layout_width="match_parent"
android:layout_height="0dp"
android:visibility="visible"
android:layout_below="@+id/linearLayout"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true" />
它有一个SimpleCursorAdapter支持的项目行的自定义列表适配器：

尝试使用SimpleCursorAdapter和自定义列表视图行在ListFragment上运行以下espresso测试时：
onData(allOf(is(instanceOf(ListFragment.class)))).check(matches(isDisplayed()));
onData(anything())
.inAdapterView(withId(R.id.listconversations))
.atPosition(0)
.perform(click());
发生以下错误：

Finish
我也尝试过：
onData(allOf(is(instanceOf(SimpleCursorAdapter.class)))).check(matches(isDisplayed()));
但这也不起作用。
答案 0 :(得分：0)
我可以使用onView来处理以下内容：
onView(allOf(withId(R.id.ib_contact_details), hasSibling(withText("Blah Blah"))))
.perform(click());
答案 1 :(得分：0)
我使用的最简单的解决方案是：
onData(CursorMatchers.withRowString("NAME", "hbhj"))
.perform(click());
在这里， NAME：是列中的。
hbhj：名称是否显示在listview元素上。
