我們在每個活動中都嵌入了WebView。 在某個頁面上，我們顯示一個進度條，然後顯示Webview，再次顯示進度條，並最終加載內容。Calabash Android無法找到未找到Webviews
最後，我們使用查詢方法觸發Javascript查詢。我們終於夾具看起來是這樣的 -
performAction('wait_for_no_progress_bars')
performAction("wait_for_view_by_id", 'webView')
performAction('wait_for_no_progress_bars')
performAction("wait_for_view_by_id", 'webView')
result =query("webView, css:"+locator)
它無法在查詢步說「不網頁視圖找到」。這之前的步驟通過（它獲取WebView），但查詢步驟失敗。 有什麼想法可能會出錯？
在研究進入robotium來源，我們發現，查詢方法在內部使用「getCurrentViews()」不僅着眼於知名度，也做了一些處理，以與高度。我們在這裏的視角相當長。這可能會導致任何問題？
控制檯輸出如下 -
