Android：使用WebView组件回调？ [英] Android: Callbacks with WebView component?

问题描述

我正在使用第三方网站进行身份验证，该网站应通过auth令牌（OAUTH）重定向回我的应用。

I am doing authentication with a third-party site that's supposed to redirect back to my app with auth token (OAUTH).

我有回调可正常工作if我通过

I have the callback working properly if I open the 3rd party site in a separate browser process via

this.startActivity(new Intent(Intent.ACTION_VIEW, uri));

但是，如果我在我的布局中嵌入一个WebView组件，并打开url，不工作。 Webview说你没有权限打开myapp：// callback？token = ....并快速刷新为网页不可用...暂时下来... blah blah

but, if I embed a WebView component in my layout, and open the url in that, the callback does not work. Webview says "You do not have permission to open myapp://callback?token=...." and quickly refreshes to "Web page not available...temporarily down...blah blah"

任何想法？

推荐答案

您需要实现 WebViewClient 在加载自定义URI之前拦截自定义URI。 Hello，WebView教程显示了一个简单的示例。他们有：

You need to implement a WebViewClient to intercept the custom URI before it is loaded. The Hello, WebView tutorial shows a simple example. Where they have:

private class HelloWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
}

您可以更改view.loadUrl（url）以检查该网址是否为您的自定义网址，并根据需要处理。

You can change "view.loadUrl(url)" to check if the URL is your custom URL and handle it however you want.
