我正在尝试构建富文本,其中第一部分显示“正在查找:”并加粗,但其余部分未加粗。这是我的代码:

SpannableStringBuilder lookingForString = new SpannableStringBuilder("Looking for: ");
lookingForString.setSpan(new StyleSpan(Typeface.BOLD), 0, lookingForString.length(),
                                         0);
int start = (lookingForString.length() - 1);
for (int i = 0; i < looking_for_names.length(); ++i) {
// No comma before the first and after the last 'Looking for' value
    if (i > 0) {
        lookingForString.append(", ");
        lookingForString.setSpan(new StyleSpan(Typeface.NORMAL), start,
                                (lookingForString.length() - 1), 0);
        start += 2;
    }

    String lfItem = looking_for_names.optString(i);
    lookingForString.append(lfItem);
    lookingForString.setSpan(new StyleSpan(Typeface.NORMAL), start,
                            (lookingForString.length() - 1), 0);
    start += lfItem.length();
}
tvLookingFor.setText(lookingForString, BufferType.SPANNABLE);

然而,结果是整行都是粗体的。我尝试了很多变体,但我无法正确控制字体……无论我如何编码,它都倾向于保留第一个字体。

我怎样才能让“寻找:”只有粗体,但其余文本是常规的(非粗体)?

如果您只需要加粗部分文本,则只需使用 html 标签。

String htmlString="<b>Looking for: Bold</b> and Normal";
tvLookingFor.setText(Html.fromHtml(htmlString), TextView.BufferType.SPANNABLE);
