Is there a XWalkView webviewclient?

Cross Walk API introduces its own names for every component. Not only the WebView is renamed to XWalkView, but also WebViewClient has its counterpart named XWalkResourceClient and WebChromeClient - XWalkUIClient. So, instead of setWebViewClient you should use setResourceClient method and pass XWalkResourceClient instance to it. In this object you can implement some required methods, for example onLoadFinished. Please, consult with Cross Walk API documentation for further details.

WebViewClient example:

    webView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            //Do stuff
        }
    });

Same thing but using XWalkView version:

xWalkView.setResourceClient(new XWalkResourceClient(xWalkView){
        @Override
        public void onLoadFinished(XWalkView view, String url) {
            super.onLoadFinished(view, url);
            //Do Stuff
        }
    });

you can use ResourceClient.

class ResourceClient extends XWalkResourceClient {
    public ResourceClient(XWalkView xwalkView) {
        super(xwalkView);
    }

    public void onLoadStarted(XWalkView view, String url) {
        mProgress = (ProgressBar) findViewById(R.id.progressBar);
        mProgress.setVisibility(View.VISIBLE);
        super.onLoadStarted(view, url);
        Log.d("INFO", "Load Started:" + url);
    }

    public void onLoadFinished(XWalkView view, String url) {
        super.onLoadFinished(view, url);
        Log.d("INFO", "Load Finished:" + url);
        bottomBar = (BottomBar) findViewById(R.id.bottomBar);
        mProgress = (ProgressBar) findViewById(R.id.progressBar);
        mProgress.setVisibility(View.GONE);
    }

    public void onProgressChanged(XWalkView view, int progressInPercent) {
        super.onProgressChanged(view, progressInPercent);
        Log.d("INFO", "Loading Progress:" + progressInPercent);
        mProgress = (ProgressBar) findViewById(R.id.progressBar);
        mProgress.setProgress(progressInPercent);
    }
