如何在webview里实现唤起QQ

[qq_31919421]

用webview浏览网页时我发现不可以打开QQ临时会话网页，其他浏览器打开可以唤起QQ，但我的工程显示这样，如图。

在shouldOverrideUrlLoading中处理。

public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if (URLUtil.isNetworkUrl(url)){
                view.loadUrl(url);
                return true;
            } else {
                try {
                    startActivity(Intent.parseUri(url, Intent.URI_INTENT_SCHEME));
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
                return true;
            }
        }
