我们在每个活动中都嵌入了WebView。 在某个页面上，我们显示一个进度条，然后显示Webview，再次显示进度条，并最终加载内容。Calabash Android无法找到未找到Webviews
最后，我们使用查询方法触发Javascript查询。我们终于夹具看起来是这样的 -
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)
它无法在查询步说“不网页视图找到”。这之前的步骤通过（它获取WebView），但查询步骤失败。 有什么想法可能会出错？
在研究进入robotium来源，我们发现，查询方法在内部使用“getCurrentViews()”不仅着眼于知名度，也做了一些处理，以与高度。我们在这里的视角相当长。这可能会导致任何问题？
控制台输出如下 -
