shouldOverrideUrlLoading不工作/捕获链接点击，而页面加载 [英] shouldOverrideUrlLoading does not work/catch link clicks while page is loading

问题描述

我使用的<一个href="http://developer.android.com/reference/android/webkit/WebViewClient.html#shouldOverrideUrlLoading%28android.webkit.WebView,%20java.lang.String%29">WebViewClient.shouldOverrideUrlLoading捕捉任何链接的点击次数在web视图。这工作约95％的时间，但有时它只是不叫。

I am using WebViewClient.shouldOverrideUrlLoading to catch any link clicks in the WebView. This works about 95% of the time, but sometimes it is simply not called.

我已经在这三种情况下注意到了这一点：

I have noticed it in these three circumstances:

1. 当链接指向的网页，他们已经在。这个人是不是一个真正的大问题，而且有报道为它错误。
2. 当页面仍在加载，如果用户点击一个链接，它很少捕获它。它只是将打开该链接而没有调用 shouldOverrideUrlLoading 。
3. 随机。虽然这个实验在过去的几个月我已经注意到，有时它只是没有抓住它。这是罕见的，但它确实发生了。

1. When the link points to the page they are already on. This one isn't a really big deal, and there is a bug reported for it.
2. While the page is still loading, if the user clicks a link, it rarely catches it. It will just open the link without ever calling shouldOverrideUrlLoading.
3. Randomly. While experimenting with this over the last couple months I have noticed that sometimes it just doesn't catch it. It is rare but it does happen.

现在我的问题主要是如何解决问题2，既然别人都少了一个大问题。但是，如果有人已经解决了1或3我很想听到它。

Now my question is mostly how to fix problem 2, since the others are less of a big deal. However, if someone has solved either 1 or 3 I would love to hear about it.

另外，我要指出，我在 shouldOverrideUrlLoading 尝试不同的返回值和我注意到，总是返回true，似乎有最好的结果，但上面仍是问题发生了。

Also, I should mention that I have tried different return values in shouldOverrideUrlLoading and I have noticed that always returning true seems to have the best result, but the issues above still happen.

推荐答案

如果HTML是你自己的，你可以替换调用自己的Java对象，注入的WebView 通过 addJavascriptInterface（）。然后，你将不再依赖于 shouldOverrideUrlLoading（）。

If the HTML is your own, you can replace all traditional links with calls to your own Java object, injected into the WebView via addJavascriptInterface(). Then you will no longer be reliant upon shouldOverrideUrlLoading().

否则，也许尝试prevent用户从与页面交互，直到 onPageFinished（）。

Otherwise, perhaps try to prevent the user from interacting with the page until onPageFinished().

我还没有遇到这个问题，但我还没有广泛使用的WebView 与任意内容，无论是。

I have not run into this problem, but I have not made extensive use of WebView with arbitrary content, either.
