在Android中使用上划线

Question

我试图在TextView中显示重复的小数，但在Html.fromHtml中使用HTML标记不起作用。有没有其他方法可以在数字上显示线条？

private static final StrikethroughSpan STRIKE_THROUGH_SPAN = new StrikethroughSpan();
...
tv.setText(s, TextView.BufferType.SPANNABLE);
Spannable spannable = (Spannable) tv.getText();
spannable.setSpan(STRIKE_THROUGH_SPAN, 0, s.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
