Espresso - 单击单个列表视图项
Espresso - click a single list view item
我尝试执行以下操作：
onView(allOf(withId(R.id.single_row_text), withText("Item1"))).perform(click());
但我得到的只是：
android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: (with id: net.test.android:id/single_row_text and with text: is "Item1")
If the target view is not part of the view hierarchy, you may need to use Espresso.onData to load it from one of the following AdapterViews:android.widget.ListView@410d6ab0

我也尝试了很多 onData 的东西，但他们都失败了：
onData(allOf(is(AnyTextView.class), withText("Item1"))).perform(click());
onData(Matchers.allOf(Matchers.is(Matchers.instanceOf(ListView.class)), Matchers.hasToString(Matchers.startsWith("Item1")))).perform(ViewActions.click());
onData(anything()).inAdapterView(withContentDescription("menu_item_icon")).atPosition(0).perform(click());
onData(hasToString(startsWith("Item1")))
.inAdapterView(withId(R.id.browse_types_list))
.perform(click());
对此有什么建议吗？谢谢！
解决方案（已更新）
原来是时间问题。我在执行测试之前 运行 Thread.sleep(5000) 成功了。
试试这个。
onData(anything()).inAdapterView(withId(R.id.list_view)).atPosition(0).perform(click());
Espresso 的美妙之处在于无需处理所有这些 'timeout' 混乱。
你是否像 Espresso 文档中提到的那样禁用了动画：
On your device, under Settings->Developer options disable the following 3 settings:
Window animation scale
Transition animation scale
Animator duration scale
?
如果您不知道 ListView 的布局 ID，您仍然可以运行对其进行 Espresso 测试：
// Perform a click on the 5th item of a ListView.
// anything() is a hamcrest matcher that always matches.
// It's useful if you don't care what the object under test is.
onData(anything()).atPosition(5).perform(click());
这将适用于显示项目列表的 Dialogs 和 DialogFragments。而且您不需要指定 ListView ID。

注意：要快速添加这些方法的导入，请将闪烁的光标放在未解析的方法上，然后执行 Android Studio ➔ Help ➔ Find Action ➔ 搜索 "show context action" 或 "show intention action" ➔ 点击结果选项 ➔ 弹出 window 会出现 ➔ 点击 "Import static method ...".您还可以为 "Show Context Actions" 分配键盘快捷键。 More info here。另一种方法是在设置中启用 "Add unambiguous imports on the fly"。
