java - 如何使用项目符号显示为输出？

Question

我通过复制项目符号并将其放置在字符符号中来使用。但问题是它显示项目符号 such blue color在手机中。我的要求是，它应该是 black arrow 。

这是我的代码:

 Spannable spannable = SpanUtils.createNestingParagraphsSpannable(strings,
'▶', mFirstLineIndent); //but this is not working as expected output.



 public static Spannable createNestingParagraphsSpannable(List<String> paragraphs,
                                                             char bulletSymbol, int indent) {

        List<ImprovedPair<Integer, Integer>> indexes = new ArrayList<>();

        StringBuilder builder = new StringBuilder();
        int count = CollectionUtils.emptyIfNull(paragraphs).size();
        for (int i = 0, last = count - 1; i < count; ++i) {
            int start = builder.length();
            if (i > 0) {
                builder.append(bulletSymbol); //here I am using the bullet symbol
                builder.append(" ");
            }

            builder.append(paragraphs.get(i));

            if (i < last) {
                builder.append("\n\n");
            }

            indexes.add(new ImprovedPair<>(start, builder.length()));
        }

尝试将“▶”替换为“\u2023”

这是您要查找的符号的 unicode。通过将此 unicode 放入字符串或字符中，将在打印时插入符号
