单击链接时，从Android WebView中的锚标记获取href值

我正在WebView中加载一个网页。网页中有一个链接，桌面上会下载文件，但在应用程序中，该链接应该显示Toast，表示该链接已被应用程序禁用。

当单击链接时，我不知道如何从锚点标记的href中获取值。

<a class="btn btn-primary" download="http://xx.xxx.com/wp-content/uploads/2015/11/abc-27-15.mp3" href="http://xx.xxx.com/wp-content/uploads/2015/11/abc-27-15.mp3">
<i class="fa fa-download"></i> Download Audio</a>

有人能分享一个关于如何做到这一点的想法或任何示例代码吗。

以下是我目前正在做的事情：

private static final String URL = "http://xx.xxx.com/wp-content/uploads/";
webView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    WebView.HitTestResult hr = ((WebView) v).getHitTestResult();
                    String extra = hr.getExtra();
                    if (extra != null && extra.startsWith(URL) && extra.endsWith(".mp3")) {
                        Log.d("WebviewActivity", "Extra: " + extra);
                        Log.d("WebviewActivity", "Contains URL");
                        return true;
                    } 
                }
                return false;
            }
        });

这种方法的问题在于：当我点击链接时，我会得到额外的网址。直到这里都很好用。但是，从下一次开始，无论我在哪里点击网络视图，都会返回相同的额外内容。所以，即使我在点击网址后点击了一张图片，我也会在额外的网址中得到相同的网址。不确定我是否做错了什么。或者这是正确的方法。

如果你需要任何细节，请告诉我。

private Handler mHandler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            // Get link-URL.
            String url = (String) msg.getData().get("url");
            // Do something with it.
            if (url != null) {
                Log.d(TAG, "URL: "+url);
            }
        }
    };

        webView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    WebView.HitTestResult hr = ((WebView) v).getHitTestResult();

                    if (hr.getType() == WebView.HitTestResult.SRC_ANCHOR_TYPE) {
                        Message msg = mHandler.obtainMessage();
                        webView.requestFocusNodeHref(msg);
                    }

                }
                return false;
            }
        });

        webView.loadUrl(mUrl);
    }

现在，我得到了在最后一个action_down事件中单击的URL。如何获取当前URL？

编辑3(尝试使用webviewclient：

 private class MyWebViewClient extends WebViewClient {
        private static final String URL = "xx.xxx.com/wp-content/uploads/";
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            if (!isFinishing())
                mProgressDialog.show();
        }
        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            mProgressDialog.dismiss();
        }
        @Override
        public void onReceivedError(WebView view, int errorCode,
                                    String description, String failingUrl) {
            super.onReceivedError(view, errorCode, description, failingUrl);
            Toast.makeText(WebviewActivity.this,
                    "Please check your internet " + "connection and try again",
                    Toast.LENGTH_SHORT).show();
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            Log.d("xxx", "Url: " + url);
            if(url.contains(URL)) {
                Log.d("xxx", "Url Contains: " + URL);
                return true;
            }
            return false;
        }
    }

mMyWebViewClient = new MyWebViewClient();
        webView.setWebViewClient(mMyWebViewClient);

点击链接时在logcat中的输出：
