如何从字符串html中添加样式以在android文本视图中显示？

String htmlString = "<b>Bold Text</b> <i>Italic Text</i>";
Spanned spannedString = Html.fromHtml(htmlString);

TextView textView = findViewById(R.id.text_view);
textView.setText(spannedString);

String htmlString = "<span style=\"color:#FF0000;\">Red Text</span>";
Spanned spannedString = Html.fromHtml(htmlString, null, new Html.TagHandler() {
    @Override
    public void handleTag(boolean opening, String tag, Editable output, XMLReader xmlReader) {
        if (tag.equalsIgnoreCase("span")) {
            if (opening) {
                // 处理<span>标签的开始
                String style = xmlReader.getAttributeValue(null, "style");
                if (style != null) {
                    // 解析CSS样式并应用到文本
                    String[] styleItems = style.split(";");
                    for (String styleItem : styleItems) {
                        String[] keyValue = styleItem.split(":");
                        if (keyValue.length == 2) {
                            String key = keyValue[0].trim();
                            String value = keyValue[1].trim();
                            if (key.equalsIgnoreCase("color")) {
                                output.setSpan(new ForegroundColorSpan(Color.parseColor(value)), output.length(), output.length(), Spannable.SPAN_MARK_MARK);
                            }
                            // 其他CSS样式的处理
                        }
                    }
                }
            } else {
                // 处理<span>标签的结束
                int spanStart = output.getSpanStart(Spannable.SPAN_MARK_MARK);
                output.removeSpan(Spannable.SPAN_MARK_MARK);
                if (spanStart >= 0) {
                    int spanEnd = output.length();
                    if (spanEnd > spanStart) {
                        // 应用样式到文本
                        output.setSpan(new StyleSpan(Typeface.BOLD), spanStart, spanEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                    }
                }
            }
        }
    }
});
