webview加载网页时,网页里有打电话的需求

private class webViewClient extends WebViewClient {
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if (url.startsWith("tel:")) {
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse(url));
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);
            }else
            view.loadUrl(url);
            return true;
        }
