Espresso Recyclerview滚动到结束 [英] Espresso Recyclerview scroll to end

问题描述

我有一个Android应用程序，该应用程序具有带有N个元素的RecyclerView，并且当滚动时该RecyclerView到达结尾时，会添加更多元素(因此，这是一个无限列表，当滚动到达底部时将加载数据).

我想测试一下，但是我还没有找到一种方法来测试.我使用具有scrollToPosition的RecyclerViewActions，但是即使我放置了最后一个位置，也没有达到终点(因为每个元素的高度都很高).

有人知道我该怎么做吗?

解决方案

我使用下面的内容滚动到我的RecyclerView的底部.

activity = mActivityTestRule.launchActivity(startingIntent);

onView(withId(R.id.recyclerView))
                .perform(RecyclerViewActions.scrollToPosition(activity.recyclerView.getAdapter().getItemCount() - 1));

然后，您将不得不使用闲置资源(或Thread.sleep())可在加载更多数据后再次调用.

I have an Android application which has a RecyclerView with N elements, and when this RecyclerView reaches to end when scrolling, then more elements are added (so, it's an infinite list which loads data when scroll reached the bottom).

I would like to test this, but I haven't found a way to do this. I use RecyclerViewActions which have scrollToPosition but even if I put the last position, the end is not reached (because the height of each element is high).

Anybody know how could I do this?

解决方案

I use the below to scroll to the bottom of my RecyclerView.

activity = mActivityTestRule.launchActivity(startingIntent);

onView(withId(R.id.recyclerView))
                .perform(RecyclerViewActions.scrollToPosition(activity.recyclerView.getAdapter().getItemCount() - 1));

You'll then have to use idling resources (or Thread.sleep()) to call this again when more data has loaded.
