Question

我正在尝试在HTML网页中加载一个部门，所以首先我开始使用带有分区的简单HTML代码...来提取我试图使用Jsoup.parse()方法解析HTML字符串的部门但是它不管用。我已经在项目中添加了Jsoup库。但每当我尝试使用

解析它

Document doc = Jsoup.parse(str);

或

 doc = Jsoup.connect(str).get();`

显示Application has unexpectedly stopped working。我不知道问题出在哪里。

Answer 1

请使用

showText.setText(Html.fromHtml(str));

而不是

showText.setText(str);

因为Html.fromHtml会给你你所期望的。

Android中的Jsoup，因NoClassDefFound错误而崩溃
