在j2me中处理文本html [英] handle text html in j2me

问题描述

我试图制作应用程序的RSS新闻，它可以给用户提供详细的新闻。

当我进入细节时，正文文本显示html标记。

这是我的照片申请：

我没有想要显示html标签。

这是我的代码，显示详细信息页面：

  private void detailScreen（News news）{
 Form form = new Form（news.getTitle（））; 
 
 StringItem detail = new StringItem（，news.getBody（）。toString（））; 
 mBackCommand = new Command（Back，Command.BACK，0）; 
 
 form.append（detail）; 
 form.addCommand（mBackCommand）; 
 form.setCommandListener（this）; 
 
 // Canvas c = new MyCanvas（this，news）; 
 
 mDisplay.setCurrent（form）; 
} 
  

请有人告诉我我在这里做错了什么？

解决方案

使用 jsoup

使用它：

  Jsoup.parse（htmlText ）.text（）
  

如果你有这个库，你的代码现在可以写成：

  private void detailScreen（News news）{
 Form form = new Form（news.getTitle（））; 
 
 StringItem detail = new StringItem（，Jsoup.parse（news.getBody（）。toString（））。text（））; 
 mBackCommand = new Command（Back，Command.BACK，0）; 
 
 form.append（detail）; 
 form.addCommand（mBackCommand）; 
 form.setCommandListener（this）; 
 
 // Canvas c = new MyCanvas（this，news）; 
 
 mDisplay.setCurrent（form）; 
} 
  

更新

其他解析器选项：

http://jericho.htmlparser.net/docs/index.html
http://jericho.htmlparser.net/docs/javadoc/net/htmlparser/jericho/TextExtractor.html

但即使在这种情况下，完整的库可能无法编译，您可能需要提取所需的类。这在使用j2me时总是如此。

这也许是有用的：

I tried to make application RSS news, and it can give detail news to user.

When I go to detail, the body text is show the html tag.

This is picture of my application:

I don't want to show html tags.

This is my code to show detail page:

private void detailScreen(News news){
    Form form = new Form(news.getTitle());

    StringItem detail = new StringItem("", news.getBody().toString());
    mBackCommand = new Command("Back", Command.BACK, 0);

    form.append(detail);
    form.addCommand(mBackCommand);
    form.setCommandListener(this);

    //Canvas c = new MyCanvas(this, news);

    mDisplay.setCurrent(form);
}

Please can someone tell me what's I'm doing wrong here?

解决方案

Its quite simple to do with jsoup

using it:

Jsoup.parse(htmlText).text()

if you have that library your code can now be written as:

private void detailScreen(News news){
    Form form = new Form(news.getTitle());

    StringItem detail = new StringItem("",Jsoup.parse(news.getBody().toString()).text());
    mBackCommand = new Command("Back", Command.BACK, 0);

    form.append(detail);
    form.addCommand(mBackCommand);
    form.setCommandListener(this);

    //Canvas c = new MyCanvas(this, news);

    mDisplay.setCurrent(form);
}

UPDATE

Other parser options:

http://jericho.htmlparser.net/docs/index.html http://jericho.htmlparser.net/docs/javadoc/net/htmlparser/jericho/TextExtractor.html

But even in this case complete library may not compile and you may have to extract the classes you need. This is always the case when working with j2me.
