问题描述
我是Android Espresso库的新手。尝试在 ViewPager 中单击 RecyclerView 项目。我搜索了互联网，但没有发现任何有关ViewPager的信息。所以我的问题是：如何使用Espresso在 ViewPager 中访问 RecyclerView 来执行点击？
I am new to Android Espresso library. Trying to test click on RecyclerView item inside the ViewPager. I've searched the Internet but found nothing about ViewPager. So my question is: how to access RecyclerView inside a ViewPager using Espresso to perform click?
推荐答案
假设您想点击 buttonClick ，这是您的RecyclerView中按钮的ID。
Let's suppose you want to tap on buttonClick, which is the id of a button inside your RecyclerView.
我使用此代码：
onView(allOf(withId(R.id.buttonToClick), isCompletelyDisplayed()))
.perform(click());
这将获取当前显示的此ID并执行单击的视图。
This gets the view with this id which is currently displayed and performs a click on it.
希望这会有所帮助。
PS：此外，在 espresso-contrib 上还有 RecyclerViewActions 您可以使用： actionOnHolderItem ， actionOnItem 和 actionOnItemAtPosition 。您可以执行以下操作：
P.S.: Also, on espresso-contrib there are RecyclerViewActions that maybe you can use: actionOnHolderItem, actionOnItem and actionOnItemAtPosition. You can do something like:
onView(withId(R.id.recyclerView))
.perform(RecyclerViewActions.actionOnItemAtPosition(0, click()));
