是 webView.loadUrl（）是异步的：它会立即返回，并不断的WebView在它自己的工作主题。

Yes, webView.loadUrl() is asynchronous: it returns immediately and WebView keeps working in it's own thread.

要监视的WebView页面加载使用WebViewClient.onPageFinished(..)$c$c>:

To monitor WebView page loading use WebViewClient.onPageFinished(..):

webview.setWebViewClient(new WebViewClient() {
    public void onPageFinished(WebView view, String url) {
        // do something here
    }
});
