Heyo,我正在使用the appearance of each track is updated
更改单词的每个字符颜色。这就是我使用它的方式:
SpannableStringBuilder
问题是,SpannableStringBuilder specialSpan = new SpannableStringBuilder();
specialSpan.append(context.getResources().getString(R.string.asdf));
specialSpan.setSpan(new ForegroundColorSpan(context.getResources().getColor(R.color.blue)), 0, 0, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
specialSpan.setSpan(new ForegroundColorSpan(context.getResources().getColor(R.color.purple)), 1, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
specialSpan.setSpan(new ForegroundColorSpan(context.getResources().getColor(R.color.orange)), 2, 2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
specialSpan.setSpan(new ForegroundColorSpan(context.getResources().getColor(R.color.green)), 3, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
userSpecialText.setText(specialSpan);
的颜色不会改变。我在这里错过了什么吗?
更新:
我正在使用另一个可用于添加TextView
Emojis
并更改检测到的用户别名的颜色
for (String part :
partofContent){
if (part.contains(":")){
int firstEq = sb.length();
Typeface font = FontCache.getTypeface("emojione-android.ttf", context);
String convertPart = Emojione.shortnameToUnicode(part, true);
sb.append(convertPart + " ");
int lastEq = sb.length();
sb.setSpan(new CustomTypefaceSpan("", font), firstEq, lastEq, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
} else {
sb.append(part + " ");
}
}
效果也很好,它在int aliasStart = sb.length();
sb.append("@" + alias + " ");
int aliasEnd = sb.length();
sb.setSpan(new MyClickableSpan("@" + alias + " "), aliasStart, aliasEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
sb.setSpan(new ForegroundColorSpan(context.getResources().getColor(R.color.miBlue)), aliasStart, aliasEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
sb.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), aliasStart, aliasEnd, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
中使用相同的ForegroundColorSpan
。
答案 0 :(得分:0)
试试这个
SpannableStringBuilder specialSpan = new SpannableStringBuilder();
specialSpan.append(context.getResources().getString(R.string.asdf));
specialSpan.setSpan(new ForegroundColorSpan(context.getResources().getColor(R.color.blue)), 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
specialSpan.setSpan(new ForegroundColorSpan(context.getResources().getColor(R.color.purple)), 1, 2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
specialSpan.setSpan(new ForegroundColorSpan(context.getResources().getColor(R.color.orange)), 2, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
specialSpan.setSpan(new ForegroundColorSpan(context.getResources().getColor(R.color.green)), 3, 4, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
userSpecialText.setText(specialSpan);
您为开始和结束指定相同意味着您指定的长度为0,而不是长度为1的跨度。
