Xamarin WebView 中tel:链接点击问题解决方案

Android 平台处理方式

自定义WebViewClient，重写ShouldOverrideUrlLoading方法，识别tel:开头的链接并唤起拨号应用：

public class CustomWebViewClient : WebViewClient
{
    public override bool ShouldOverrideUrlLoading(WebView view, IWebResourceRequest request)
    {
        var url = request.Url.ToString();
        if (url.StartsWith("tel:"))
        {
            var intent = new Intent(Intent.ActionDial, Android.Net.Uri.Parse(url));
            view.Context.StartActivity(intent);
            return true;
        }
        return base.ShouldOverrideUrlLoading(view, request);
    }
}

给WebView绑定这个自定义Client：

webView.SetWebViewClient(new CustomWebViewClient());

iOS 平台处理方式

自定义WKNavigationDelegate，在DecidePolicy方法中拦截tel:链接并触发拨号：

public class CustomNavigationDelegate : WKNavigationDelegate
{
    public override void DecidePolicy(WKWebView webView, WKNavigationAction navigationAction, Action<WKNavigationActionPolicy> decisionHandler)
    {
        var url = navigationAction.Request.Url;
        if (url.Scheme.Equals("tel", StringComparison.OrdinalIgnoreCase))
        {
            UIApplication.SharedApplication.OpenUrl(url);
            decisionHandler(WKNavigationActionPolicy.Cancel);
            return;
        }
        decisionHandler(WKNavigationActionPolicy.Allow);
    }
}

将代理绑定到WebView：

webView.NavigationDelegate = new CustomNavigationDelegate();

通用检查项

确认WebView已开启JavaScript支持（若网页依赖JS处理链接跳转）：

// Android
webView.Settings.JavaScriptEnabled = true;

// iOS
var config = new WKWebViewConfiguration();
var webView = new WKWebView(View.Frame, config);
