测试场景等待启动屏幕完成，滚动浏览 RecyclerView，然后单击其中的随机项目。您的 XML 布局包括一个 CollapsingToolbarLayout 和一个名为 mainAdsRecyclerView 的 RecyclerView，其中似乎包含广告项。
您的 UI 测试类 BaselineProfileGenerator 包含测试场景每个步骤的方法：
这个设置看起来很全面，涵盖了等待时间、滚动操作以及与 RecyclerView 的交互。但是，如果您遇到任何问题或需要进一步帮助，请随时询问！

我也试过这个
@RunWith(AndroidJUnit4::class)
class RecyclerViewActivityBaselineProfileGenerator : BaselineProfileGenerator() {
override fun MacrobenchmarkScope.profileBlock() {
// Start into the RecyclerViewActivity
startActivityAndWait()
device.waitForIdle(20_000)
// Scrolling RecyclerView journey
device.findObject(By.res("com.camelan.main", "mainAdsRecyclerView")).also {
it.setGestureMargin(device.displayWidth / 10)
it.fling(Direction.DOWN)
it.fling(Direction.UP)
}
}
}
但是我收到了这个错误
