android - 第一个 setSpan 不起作用

Question

final StyleSpan bss = new StyleSpan(android.graphics.Typeface.BOLD);
final SpannableString ss = new SpannableString("How to " + text + " in " + type);
ss.setSpan(bss, 7, text.length() + 7, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
ss.setSpan(bss, 7 + text.length() + 4, ss.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
textView.setText(ss);

我想制作 text 和 type BOLD。但只有字体是粗体。

我错过了什么？

Answer 1

根据文档:

setSpan(Object what, int start, int end, int flags) Attach the specified markup object to the range start…end of the text, or move the object to that range if it was already attached elsewhere.

StyleSpan 只能在 Spannable 中使用一次。您需要为每个 text 和 type

创建一个 StyleSpan
