@seveniruby

请问你们帮我看看上面的问题吗？

#1 楼 @daibiao83 switch_to.context 并不是你想象的真正的切进去，而是拿到和 webview 之间的调试通道，你拿不到的原因和 floating xxx 没有关系。要看你的 webview 能否调试。

@lihuazhang
非常感谢你的回复，我想请问一个问题，如何判断 webview 是否能够访问？
其次，我找开发把 floating action button 移除掉后，是可以切换到 webview 的

#3 楼 @daibiao83 关键我不知道你说的找不到 webview 是个什么样子的场景

我是用 python 写的 code

current_context = self.driver.contexts
print current_context

打印出来只有 [u"NATIVE_APP"]

@lihuazhang 同样的 python 脚本，当把 floating action button 移除后得到的结果是

[u'NATIVE_APP', u'WEBVIEW_com.contactexplorer']

@chenhengjie123 遇到过这种问题吗？

#7 楼 @lihuazhang 目前没遇到过。我找个 sample 试下先。

#8 楼 @chenhengjie123 用 testerhome 的 android 客户端就可以了。 帖子那里就是用的 floating action button

#9 楼 @lihuazhang
#6 楼 @daibiao83 手上没有 4.4+ 的真机。。。用 genymotion 试了下 testerhome app ，可以找到 webview 的 context：

[u'NATIVE_APP', u'WEBVIEW_com.testerhome.nativeandroid']

appium 版本：1.4.13

@chenhengjie123
非常感谢！我也用的是 1.4.13.1， 真机是 LG G2(4.4.2), 奇怪，为什么我不行？难道我们的 app 有什么特别？还是我自己做的有问题

#11 楼 @daibiao83 贴下你的代码吧。

#12 楼 @lihuazhang @chenhengjie123

sorry, 又打扰你们了,我的问题还没有解决，不过好像我们使用的是 layout 不是标准的 floating action button
请问可以给我一个邮箱什么的，我发一个简单的测试 app 给你们，帮忙看看可以吗？
非常感谢

#14 楼 @daibiao83
社区里找不到大家的信息吗？

@lihuazhang 谢谢，邮件已经发送，请查收

#16 楼 @daibiao83 1. 使用 markdown 格式来发帖子和回帖。2. 邮件已经收到，你代码写错了而已。

@lihuazhang , 请问帮忙指出错在哪些，非常感谢！

@lihuazhang 

上次我发给你的代码，其实第二和第三个find是没有执行，第一个就点击错误。

def test_test(self):
        print 'Start to record Launch time...'
        time.sleep(1)
        current_context = self.driver.contexts
        print current_context
        self.driver.find_element_by_class_name("android.widget.Button").click()
        self.driver.find_element_by_id("com.morningeast.layouttest:id/my_button").click()

下面两行是指的同一个操作, 两个都不是click 按钮“Click me”， 而都是点击了那个红色的图标。

self.driver.find_element_by_class_name("android.widget.Button").click()
self.driver.find_element_by_id("com.morningeast.layouttest:id/my_button").click()

#19 楼 @daibiao83 麻烦你自己研究下，排查方式就这么几种。另外请用真机试试看。另外描述问题，清晰一点，一步到位，不要浪费大家时间。

#19 楼 @daibiao83 话说。。。markdown 不是这样用的。。。。
