如何知道哪个单词有下划线？

我可以使用以下方法在编辑文本框中的单词下划线：

contentText.getEditableText().setSpan(new UnderlineSpan(), position, endLen, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

在我给单词划下划线后，是否有任何方法可以让我知道哪个单词被下划线？这是因为我需要知道有多少个单词以及下划线的单词是什么。预先感谢您回答我的问题。

您可以使用
getSpanEnd（对象标签）和 getSpanStart(Object tag) 来确定跨度的开始和结束。唯一的事情是您需要引用原始 UnderlineSpan 对象。

我将这样做。

UnderlineSpan span = new UnderlineSpan();
contentText.getEditableText().setSpan(span, 0, 5, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

Log.d("Span", "___Start___"+contentText.getEditableText().getSpanStart(span));
Log.d("Span", "___End___"+contentText.getEditableText().getSpanEnd(span));

You can use
getSpanEnd(Object tag) and getSpanStart(Object tag) to determine the start and end of the span. The only thing is u need to have reference to original UnderlineSpan Object.

Here is how I would do it.

UnderlineSpan span = new UnderlineSpan();
contentText.getEditableText().setSpan(span, 0, 5, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

Log.d("Span", "___Start___"+contentText.getEditableText().getSpanStart(span));
Log.d("Span", "___End___"+contentText.getEditableText().getSpanEnd(span));
