Android:WebView 组件的回调? [英] Android: Callbacks with WebView component?

问题描述

我正在使用第三方站点进行身份验证，该站点应该使用身份验证令牌 (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).

如果我通过

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

但是，如果我在布局中嵌入一个 WebView 组件，并在其中打开 url，则回调不起作用.Webview 显示您无权打开 myapp://callback?token=...."并快速刷新为网页不可用...暂时关闭...等等"

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"

有什么想法吗?

推荐答案

你需要实现一个 WebViewClient 在加载之前拦截自定义 URI.Hello, WebView 教程 展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 URL 是否是您的自定义 URL 并根据需要进行处理.

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