I am trying to open a html/javascript webpage, hosted on my localhost for now, in my android application through a webview. The page is suppose to just close after 2 sec through the below code
我正在尝试通过 webview 在我的 android 应用程序中打开一个 html/javascript 网页，该网页目前托管在我的本地主机上。该页面假设通过以下代码在 2 秒后关闭
<script type="text/javascript">
alert('hello');
setInterval(function(){window.close();},2000);
</script>
I am able to get the hello alert by using WebChromeClient. But the window.close is still not working. Any help would be appreciated.
我可以通过使用 WebChromeClient 获得 hello 警报。但是 window.close 仍然无法正常工作。任何帮助，将不胜感激。

PS：这是我加载 URL 的方式：
WebSettings ws = webView.getSettings();
ws.setJavaScriptEnabled(true);
ws.setJavaScriptCanOpenWindowsAutomatically(true);
webView.loadUrl("http://192.168.1.137/abc.html");
webView.setWebChromeClient(new WebChromeClient());

Try this :
试试这个 ：
WebChromeClient webClient = new WebChromeClient(){
public void onCloseWindow(Window w){
super.onCloseWindow(w);
Log.d(TAG, "Window close");
}
};
Description :
描述 ：
public void onCloseWindow (WebView window)
Notify the host application to close the given WebView and remove it from the view system if necessary. At this point, WebCore has stopped any loading in this window and has removed any cross-scripting ability in javascript.
通知宿主应用程序关闭给定的 WebView 并在必要时将其从视图系统中删除。此时，WebCore 已停止在此窗口中加载任何内容，并删除了 javascript 中的任何跨脚本功能。

It's not possible on android version > KITKAT. But I have find solution. If android build version > KITKAT, I have detected message from js on server side in method onConsoleMessage of WebChromeClient class http://developer.android.com/reference/android/webkit/WebChromeClient.html. It works for me.
在 android 版本 > KITKAT 上是不可能的。但我已经找到了解决方案。如果android构建版本> KITKAT，我在WebChromeClient类http://developer.android.com/reference/android/webkit/WebChromeClient.html的onConsoleMessage方法中检测到来自服务器端js的消息。这个对我有用。
