我有一个字符串
1 Friend | O Reviews | 0 Coupons
我正在使用以下代码
SpannableString hashText = new SpannableString(TextUtils.concat(
friendsText,
" | ",
reviewsText,
" | ",
couponsText
).toString());
Matcher matcher = Pattern.compile("\\s* | \\s*").matcher(hashText);
while (matcher.find())
{
hashText.setSpan(new ForegroundColorSpan(getResources().getColor(R.color.blue)), matcher.start(), matcher.end(), 0);
}
detailsText.setText(hashText);
我想改变|的颜色从TextView原始灰色到蓝色。 上面的代码什么也没做。我做错了什么。

试试这个,
Spannable spannable = new SpannableString(text);
int index = text.indexOf(“|”);
while ( index >= 0) {
spannable.setSpan(new ForegroundColorSpan(Color.BLUE), index, index + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
index = text.indexOf(“|”, index + 1);
}

试试这个
String text = TextUtils.join(" | ", Arrays.asList(new String[]{"1 Friend", "1 Review", "1 Coupons"}));
Spannable spannable = new SpannableString(text);
int index = text.indexOf('|');
while (index >= 0) {
spannable.setSpan(new ForegroundColorSpan(Color.BLUE), index, index + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
index = text.indexOf('|', index + 1);
}
detailsText.setText(hashText);

即使这里是接受的答案,但我想为用户分享最简单的方法。
public void setHighLightedText(TextView tv, String textToHighlight) {
String tvt = tv.getText().toString();
int ofe = tvt.indexOf(textToHighlight, 0);
Spannable wordToSpan = new SpannableString(tv.getText());
for (int ofs = 0; ofs < tvt.length() && ofe != -1; ofs = ofe + 1) {
ofe = tvt.indexOf(textToHighlight, ofs);
if (ofe == -1)
break;
else {
// you can change or add more span as per your need
wordToSpan.setSpan(new RelativeSizeSpan(2f), ofe,ofe + textToHighlight.length(), 0); // set size
wordToSpan.setSpan(new ForegroundColorSpan(Color.RED), ofe, ofe + textToHighlight.length(), 0);// set color
tv.setText(wordToSpan, TextView.BufferType.SPANNABLE);
}
}
}
将此方法称为
textView.setText("1 Friend | O Reviews | 0 Coupons");
setHighLightedText(textView,"|");
