在浏览该页面后，您是否尝试过此操作

String url=myWebView.getUrl().toString();

        String[] spli = url.split("/");
        if (spli[spli.length-1]!=null){
            String data = spli[spli.length-1];
            Toast.makeText(getApplicationContext(), ""+data, Toast.LENGTH_SHORT).show();
        }

或者你可以试试这个。

WebView webview = new WebView(context);
webview.setWebViewClient(new WebViewClient()
        {
            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);

                Log.d("WebView", "your current url when webpage loading.." + url);
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                Log.d("WebView", "your current url when webpage loading.. finish" + url);
                super.onPageFinished(view, url);
            }

            @Override
            public void onLoadResource(WebView view, String url) {
                // TODO Auto-generated method stub
                super.onLoadResource(view, url);
            }
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                System.out.println("when you click on any interlink on webview that time you got url :-" + url);
                return super.shouldOverrideUrlLoading(view, url);
            }
        });
