HtmlView

注意 开发中部分无法使用 Android Html富文本view,让TextView显示html,目前已经支持一些基本的标签。

软件截图

 

• 替换了android Html 类的html解析器（应该说是xml解析器,他的做法是先将html转换为xml然后再解析）
• 全标签支持自定义,源码中常用标签无法自定义,自定义的mTagHandler无法处理如 br p ul...等标签
• 属性解析器自定义,自带的属性解析器只能获取到color background-color text-align text-decoration等属性

附android.text.Html类中无法自定义的标签

private void handleStartTag(String tag, Attributes attributes) {
        if (tag.equalsIgnoreCase("br")) {
            // We don't need to handle this. TagSoup will ensure that there's a </br> for each <br>
            // so we can safely emit the linebreaks when we handle the close tag.
        } else if (tag.equalsIgnoreCase("p")) {
            startBlockElement(mSpannableStringBuilder, attributes, getMarginParagraph());
            startCssStyle(mSpannableStringBuilder, attributes);
        } else if (tag.equalsIgnoreCase("ul")) {
            startBlockElement(mSpannableStringBuilder, attributes, getMarginList());
