java.lang.IllegalStateException：沒有在位置視野持有人：一箇中等大小的手機1

Question

點擊一個回收視圖列表項（含咖啡UI自動化測試）工作正常

onView(withId(R.id.rv_recycler_view)) 
       .perform(actionOnItemAtPosition(i, click()));

編輯

現在我看到堆棧跟蹤信息的一些重要的一點，但還是做在位置沒有觀點持有者：ES不能解決爲什麼平板電腦僅

onView(withId(R.id.rv_recycler_view)) 
       .perform(actionOnItemAtPosition(i, click()));
