如何在WebView中进行字符编码？(How to do Character Encoding in a WebView?)

我有一个应用程序，其中有几个WebViews，每个显示一段描述文本。 几乎所有的人都在其中出现乱码，通常是单引号或双引号。

例如，一个字符串应该如下所示：

身体'N'空间

结束在WebView中看起来像这样：

身体ÂN空间

这是我第一次尝试：

textWebView.loadData(getHtmlDescription(), "text/html", "UTF-8");

我最终尝试了许多解决方案，包括以下内容：

在loadData之前添加：

WebSettings webSettings = textWebView.getSettings(); webSettings.setDefaultTextEncodingName("UTF-8");

将loadData更改为loadDataWithBaseURL ：

WebSettings webSettings = textWebView.getSettings(); webSettings.setDefaultTextEncodingName("UTF-8"); textWebView.loadDataWithBaseURL(null, getHtmlDescription(), "text/html", "UTF-8", null);

将"text/html"改为"text/html; charset=UTF-8" ：

WebSettings webSettings = textWebView.getSettings(); webSettings.setDefaultTextEncodingName("UTF-8"); textWebView.loadDataWithBaseURL(null, getHtmlDescription(), "text/html; charset=UTF-8", "UTF-8", null);

不幸的是，这些解决方案中没有任何一个能解决问题

I have an app in which there are several WebViews, each displaying a paragraph of description text. Almost all of them have garbled characters in them, usually where there are single quotes or double quotes.

For example, a string which should look like the following:

Body ‘N’ Space

Ends up looking like this in the WebView:

Body ÂNÂ Space

Here's what I first tried:

textWebView.loadData(getHtmlDescription(), "text/html", "UTF-8");

I ended up trying many solutions, including the following:

Adding this before loadData:

WebSettings webSettings = textWebView.getSettings(); webSettings.setDefaultTextEncodingName("UTF-8");

Changing loadData to loadDataWithBaseURL:

WebSettings webSettings = textWebView.getSettings(); webSettings.setDefaultTextEncodingName("UTF-8"); textWebView.loadDataWithBaseURL(null, getHtmlDescription(), "text/html", "UTF-8", null);

Changing "text/html" to "text/html; charset=UTF-8":

WebSettings webSettings = textWebView.getSettings(); webSettings.setDefaultTextEncodingName("UTF-8"); textWebView.loadDataWithBaseURL(null, getHtmlDescription(), "text/html; charset=UTF-8", "UTF-8", null);

And unfortunately, none of those solutions did the trick!

最满意答案

在尝试了所有这些解决方案之后，我终于试图找到并替换所有可以看到的坏字符。 这太繁琐而且效率低下，但不知何故，我偶然发现了以下两行解决方案，它们完成了所有工作！

在我的getHtmlDescription()方法中，我添加了这两行：

description = description.replace("Â", ""); description = Html.fromHtml(description, Html.FROM_HTML_MODE_LEGACY).toString(); return description;

After trying all those solutions without success, I ended up trying to just find and replace all the bad characters I could see. That was just too cumbersome and inefficient, but somehow I stumbled on the following two-line fix that did the job for all of it!

In my getHtmlDescription() method, I added these two lines:

description = description.replace("Â", ""); description = Html.fromHtml(description, Html.FROM_HTML_MODE_LEGACY).toString(); return description;
