WebView-下载javascript，css和图像
[英]WebView - Download javascript, css and images
问题描述
I am saving the content of WebView so that I can show that content when I launch my app the next time. 
我正在保存WebView的内容，以便下次启动应用程序时可以显示该内容。 I followed this which works almost as I wanted. 我遵循了这个程序 ，几乎可以按照我的意愿工作。
@JavascriptInterface
public void setHtml(String html) {
SharedPreferences settings = getSharedPreferences("preferences", MODE_PRIVATE);
this.html = html;
SharedPreferences.Editor prefEditor = settings.edit();
prefEditor.putString("ActivityHtml", html);
prefEditor.commit();
Log.d("html", html);
setChanged();
notifyObservers(html);
}
And then : 接着 ：
view.loadDataWithBaseURL("", settings.getString("ActivityHtml", ""), "text/html", "UTF-8", "");
However, when I see the html in Log, the Javascript and CSS have server paths like : 但是，当我在Log中看到html时，Javascript和CSS的服务器路径如下：
<link href="/Content/Sass/style_sass.css?version=1.0.1.15" rel="stylesheet">
<img src="../Images/magnify_black.png" />
Now because of this, only the text content shows up while the images aren't shown. 现在，由于这个原因，只有文本内容显示，而没有显示图像。 Like this : 像这样 ：
How may I get the images, css and javascript in HTML ? 如何获取HTML中的图像，CSS和javascript？
Just to tell I already have following in place : 只是说我已经有以下位置：
view.getSettings().setLoadsImagesAutomatically(true);
view.getSettings().setJavaScriptEnabled(true);

I think you should load CSS from Assets or SDcard,just like this: 我认为您应该从Assets或SDcard加载CSS，就像这样：
WebView wv = new WebView(context);
StringBuilder html = new StringBuilder();
html.append("<html>");
html.append("<head>");
html.append("<link rel=stylesheet href='css/style.css'>");
html.append("</head>");
html.append("<body>");
html.append("<h1>Some Heading</h1>");
html.append("<p>Some HTML content</p>");
html.append("<p><img style='width: 100%;' src='spidermen.jpg' /></p>");
html.append("</body></html>");
wv.loadDataWithBaseURL("file:///android_asset/", html.toString(), "text/html", "UTF-8", "");
and put the files in the right place. 并将文件放在正确的位置。

Use 采用
view.getSettings().setJavaScriptEnabled(true);
view.getSettings().setBuiltInZoomControls(true);
view.getSettings().setDomStorageEnabled(true);
view.requestFocus(View.FOCUS_DOWN);
view.setWebChromeClient(new WebChromeClient());
view.loadDataWithBaseURL("file:///android_asset/",settings.getString("ActivityHtml", ""),"text/html", "utf-8", null);
and the CSS part you need to place it locally in your assets folder. 和CSS部分，您需要将其本地放置在资产文件夹中。
