webviewclient

问题 is there any possibility to intercept when a user clicks on a html button? I ve an webviewclient that load a login page with two buttons. Allow and Deny.

问题 I've got a very basic WebView which works until I try to add a custom webViewClient where it stops processing JavaScript. Am I doing something wrong? Is there another way to get rid of the address bar and menu options in the WebView? browser = (WebView) findViewById(R.id.webkit); WebSettings webSettings = browser.getSettings(); webSettings.setJavaScriptEnabled(true); // uncommenting this line will remove address bar, but also stop JavaScript from loading //browser.setWebViewClient(new
