By default, WebView doesn't support multiple windows. 默认情况下， WebView不支持多个窗口。 If you check, I believe the parent field actually isn't set and doesn't point to the parent window (or anything at all). 如果您进行检查，我相信实际上未设置parent字段，并且它不指向父窗口（或任何其他窗口）。 The same applies to other similar fields like opener and top . 这同样适用于其他类似字段，例如opener和top 。

You might be able to work through this by enabling support for multiple windows and then implementing onCreateWindow in your WebChromeClient . 您可以通过启用对多个窗口的支持，然后在WebChromeClient实现onCreateWindow来WebChromeClient 。 I think there's some more you have to do, but it's been a while and I don't recall the details. 我认为您还有更多要做的事情，但是已经有一段时间了，我不记得细节了。

One way I've hacked around this in the past is to use setJavascriptInterface and just set the name to parent or whichever field you want. 我过去解决此问题的一种方法是使用setJavascriptInterface ，并将名称设置为parent或所需的任何字段。 Implement the appropriate methods as necessary on your Java object. 根据需要在Java对象上实现适当的方法。 This can get a bit messy, but it works. 这可能会有点混乱，但是可以。
