更改Android Webview哈希而不重新加载页面

问题描述

我有一个自定义的Webview设置，该设置运行良好，但我希望能够:

I'm got a custom webview setup which is working pretty well, but I'd like to be able to either:

1，更改url哈希，而不会在webview重新加载页面(这会丢失我的js应用程序的状态)

1, change the url hash without the webview reloading the page (it would lose the state of my js app)

2，从android内调用一些位于我网页内的js.不幸的是，我无法更改网站内的任何JS，因此无法自定义编写任何JS来放置在网站上，尤其是针对这份工作，我唯一能控制的就是Android应用程序.

2, call some js that sits within my web page from within android. I can't change any JS within the site, unfortunately, so can't custom write any js to put on the site especially for the job, the only stuff I have control over is the Android app.

有人能想到一种方法来做这两种方法吗?

Can anyone think of a way of doing either of these?

谢谢.

推荐答案

对于#2，您的Activity可以调用JavaScript方法.您所要做的就是通过适当的JavaScript调用来调用loadUrl方法:

For #2, your Activity can invoke JavaScript methods. All you have to do is call the loadUrl method with the appropriate JavaScript call:

mWebView.loadUrl("javascript:wave()");
