Android WebView，如何在应用程序中处理重定向而不是打开浏览器 [英] Android WebView, how to handle redirects in app instead of opening a browser

问题描述

所以现在在我的应用程序中，我正在访问的 URL 有一个重定向，当发生这种情况时，WebView 将打开一个新的浏览器，而不是留在我的应用程序中.有没有办法可以更改设置，以便视图像平常一样重定向到 URL，但留在我的应用程序中而不是打开新浏览器?

So right now in my app the URL I'm accessing has a redirect, and when this happens the WebView will open a new browser, instead of staying in my app. Is there a way I can change the settings so the View will redirect to the URL like normal, but stay in my app instead of opening a new browser?

我想要重定向 URL，我只是不知道如何创建它，所以访问该 URL 的唯一方法是通过一个会导致重定向到我想要的 URL.

I want the redirecting URL, I just don't know how to create it, so the only way to get to that URL is through one that will cause a redirect to the one I want.

例如:当您访问这里时:http://www.amazon.com/gp/aw/s/ref=is_box_/k=9780735622777 注意它如何将 URL 重定向到实际产品.在我的应用程序中，如果我在新浏览器中打开它，它会做得很好，但是如果我将它与 WebView 一起保存在我的应用程序中，它将显示为好像在搜索 k=9780735622777，如下所示:http://www.amazon.com/gp/aw/s/ref=is_s_?k=k%3D9780735622777&x=0&y=0.或者，它将在浏览器中打开视图并显示合适的内容.但是，我想将所有内容保留在我的应用中.

For example: When you go here: http://www.amazon.com/gp/aw/s/ref=is_box_/k=9780735622777 notice how it will redirect the URL to the actual product. In my app, if I open it in a new browser, it will do that just fine, however if I keep it in my app with a WebView, it will show up as though it's doing a search for k=9780735622777, like this: http://www.amazon.com/gp/aw/s/ref=is_s_?k=k%3D9780735622777&x=0&y=0 . OR, it will open the view in the browser and show what is appropriate. However, I want to keep everything in my app.

推荐答案

创建一个 WebViewClient，并覆盖 shouldOverrideUrlLoading 方法.

Create a WebViewClient, and override the shouldOverrideUrlLoading method.

webview.setWebViewClient(new WebViewClient() {
    public boolean shouldOverrideUrlLoading(WebView view, String url){
        // do your handling codes here, which url is the requested url
        // probably you need to open that url rather than redirect:
        view.loadUrl(url);
        return false; // then it is not handled by default action
   }
});
