如何在Espresso中单击SimpleCursorAdapter ListFragment项目

Question

使用通过xml:从"活动"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

当尝试在具有SimpleCursorAdapter和自定义listview行的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());

出现以下错误：

Finish

我也试过：

onData(allOf(is(instanceOf(SimpleCursorAdapter.class)))).check(matches(isDisplayed()));

但这也没用。

Answer 1

我可以让onView处理以下内容：

onView(allOf(withId(R.id.ib_contact_details), hasSibling(withText("Blah Blah"))))
            .perform(click());

Answer 2

我使用的最简单的解决方案是：

 onData(CursorMatchers.withRowString("NAME", "hbhj"))
            .perform(click());

在这里，NAME：是的列。

hbhj：显示在listview元素上的名称。
