问题 This question already has answers here : JavaScript: document.getElementById slow performance? (10 answers) Closed 3 years ago . I often use the method getElementById("id1"); in my methods.

Is there a way to override the behavior of WebView?

由 岁酱吖の 提交于 2019-12-21 05:18:08
问题 I get the WebView from my layout: WebView webView = (WebView) rootView.findViewById(R.id.myWebView); I want to override the behavior of onKeyDown . Normally, I can override it by subclassing. WebView webView = new WebView(this) { @Override public boolean onKeyDown (int keyCode, KeyEvent event) { // Do my stuff.... } } However, since I got the WebView by using findViewById , is there a way to override the method? P.S: It is actually a much more complicated case, and I can't Override onKeyDown

由 南笙酒味 提交于 2019-12-21 04:28:15
问题 I am facing a strange problem with Tomcat 8 and CORS. I am developing a Hybrid web app using ionicframework, AngularJS, Cordova as front end and Tomcat 8 and Spring 3 as back-end. For easy development I am testing the functionality in chrome , where things are working fine. I added CORS filter with standard configuration to allow CROSS ORIGIN requests from browser. Today I converted my app into Android App and started making AJAX calls to tomcat server. To my surprise things stopped working .
