Android webView shouldOverrideUrlLoading for iframes [英] Android webView shouldOverrideUrlLoading for iframes

问题描述

我有一个受Javascript控制的本地网站，并将其加载到WebView中。该网站实际上是一个带有iframe的主页面，其内容根据用户输入而变化。主页上有一个下一步按钮，用于运行一些javascript函数，并决定在iframe中加载哪个页面（通过document.getElement（...）。src =）

I have a local website that is Javascript controlled and am loading it in a WebView. The website is really one main page with an iframe whose content changes based on user input. There is a "Next" button on the main page that runs some javascript functions and decides which page to load in the iframe (via document.getElement(...).src = )

在Android 2.1中，一切都运行良好 - 模拟和手机。 webview正在正确加载所有页面。
我在2.2手机上测试了它，每当我点击Next，页面（应该在iframe中加载）都会在默认浏览器中加载。

In Android 2.1 things were working fine - simulated and on phone. The webview was loading all the pages properly. I tested it on a 2.2 phone and whenever I click Next the page (that should be loaded in the iframe) is loaded in the default browser.

I定义了一个意图过滤器

I defined an intent filter

   <intent-filter>
     <action android:name="android.intent.action.VIEW" />
     <category android:name="android.intent.category.DEFAULT" />
     <category android:name="android.intent.category.BROWSABLE" />
     <data
       android:scheme="file"
       android:host="*"
       android:pathPrefix="sdcard/Android/data/android.website/files/pages"
     />
    </intent-filter>

希望它将页面请求重定向到活动，但它不起作用。网址仍然由浏览器加载。

hoping that it would redirect the page requests to the activity, but it doesn't work. The url is still loaded by the browser.

使用shouldOverredeUrlLoading不能正常工作，因为加载的链接是内部框架之一。我尝试加载javascript代码，将该url设置为iframe的src，但无法正常工作。

Using shouldOverredeUrlLoading doesn't work well because the link that is loaded is the one of the internal frame. I tried loading instead javascript code that sets that url as the src of the iframe, but didn't work.

奇怪的是，这只发生在2.2手机上。在2.2模拟器中它工作正常。

It's weird that this only happens on the 2.2 phone. In a 2.2 emulator it works fine.

任何想法？

推荐答案

尝试向WebView提供您自己的 WebViewClient 。你应该覆盖 shouldOverrideUrlLoading（..） 并返回 false 。

Try providing your own WebViewClient to WebView. You should override shouldOverrideUrlLoading(..) and return false.
