Android：如何使用Html.TagHandler？

所以，我终于自己弄清楚了。

public class MyHtmlTagHandler implements TagHandler {    public void handleTag(boolean opening, String tag, Editable output, XMLReader xmlReader) {        if(tag.equalsIgnoreCase("strike") || tag.equals("s")) { processStrike(opening, output);        }    }    private void processStrike(boolean opening, Editable output) {        int len = output.length();        if(opening) { output.setSpan(new StrikethroughSpan(), len, len, Spannable.SPAN_MARK_MARK);        } else { Object obj = getLast(output, StrikethroughSpan.class); int where = output.getSpanStart(obj); output.removeSpan(obj); if (where != len) {     output.setSpan(new StrikethroughSpan(), where, len, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); }        }    }    private Object getLast(Editable text, Class kind) {        Object[] objs = text.getSpans(0, text.length(), kind);        if (objs.length == 0) { return null;        } else { for(int i = objs.length;i>0;i--) {     if(text.getSpanFlags(objs[i-1]) == Spannable.SPAN_MARK_MARK) {         return objs[i-1];     } } return null;        }    }}

对于您的TextView，您可以这样称呼：

myTextView.setText (Html.fromHtml(text.toString(), null, new MyHtmlTagHandler()));

如果有人需要它。
