Question

我正在使用SpannableStringBuilder在textview上设置文本，但是在不同的设备上却给我不同的结果。

这是spannableString构建器的代码

 SpannableStringBuilder builder = new SpannableStringBuilder();
        SpannableString first = new SpannableString("Directions to Send or Clear Alert:\n\n" +
                "Option 1 of 2: To Send Alert, click the \"");
        first.setSpan(new ForegroundColorSpan(Color.BLACK), 0, first.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
        first.setSpan( new StyleSpan(Typeface.BOLD), 0,  first.length()-27, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

        SpannableString second = new SpannableString("Match / STOP!");
        second.setSpan(new ForegroundColorSpan(Color.RED), 0, second.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);

        SpannableString third = new SpannableString("\" button next to the matching person.\n" +
                "Option 2 of 2: To Clear Alert, you can choose either of these 2 options:\n");
        third.setSpan(new ForegroundColorSpan(Color.BLACK), 0, third.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
        third.setSpan( new StyleSpan(Typeface.BOLD), 38,  53, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

        SpannableString third1 = new SpannableString("A) Click any of the \"");
        third1.setSpan(new ForegroundColorSpan(Color.BLACK), 0, third1.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
        third1.setSpan( new StyleSpan(Typeface.BOLD), 0,  1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

        SpannableString four = new SpannableString("No Match / CONTINUE");
        four.setSpan(new ForegroundColorSpan(Color.parseColor("#008000")), 0, four.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);

        SpannableString five = new SpannableString("\" buttons.\n" +
                "B) Click on the \"X\" (clear) button at the top right of this message screen.");
        five.setSpan(new ForegroundColorSpan(Color.BLACK), 0, five.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
        five.setSpan( new StyleSpan(Typeface.BOLD), 11,  12, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

        builder.append(first);
        builder.append(second);
        builder.append(third);
        builder.append(third1);
        builder.append(four);
        builder.append(five);

        headingTv.setText(builder);

在某些设备上，这样显示的文本是正确的，

但是在像google pixel2这样的某些设备中，它看起来像这样，太可怕了。

有人可以帮助我解决这个问题的原因吗？

试一下

String first = "Directions to Send or Clear Alert:\n\n" + "Option 1 of 2: To Send Alert, click the \"";
String second = "Match / STOP!";
String third = "\" button next to the matching person.\n" + "Option 2 of 2: To Clear Alert, you can choose either of these 2 options:\n";
String third1 = "A) Click any of the \"";
String four = "No Match / CONTINUE";
String five = "\" buttons.\n" + "B) Click on the \"X\" (clear) button at the top right of this message screen.";


int blackColor = ContextCompat.getColor(mContext,R.color.black);
Spanned third1Spanned = setSpanColor(third1, blackColor);
headingTv.setText(TextUtils.concat(
        first,
        " " ,
        second,
        " " ,
        third,
        " " ,
        third1Spanned,
        " " ,
        four,
        " " ,
        five));


public static Spanned setSpanColor(String s, int color) {
    SpannableString ss = new SpannableString(s);
    ss.setSpan(new ForegroundColorSpan(color), 0, s.length(), 0);
    ss.setSpan(new StyleSpan(android.graphics.Typeface.BOLD),0,s.length(),SPAN_EXCLUSIVE_EXCLUSIVE);
    return ss;
}

我试图从complete语句中读取字符串的开始和结束位置，然后将其设置为Color或font style。

    String completeStatement = "A) Click any of the No Match / CONTINUE";//complete statement /line
                String search = "No Match / CONTINUE";



                Pattern word = Pattern.compile(search);

                Matcher match = word.matcher(completeStatement);
                int start = -1;
                int end = -1;

                while (match.find()) {
                    start = match.start();
                    end = match.end();
                }


                SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder(offerExpiredStatement);
                spannableStringBuilder.setSpan(new android.text.style.StyleSpan(android.graphics.Typeface.BOLD),
                        start, end,
                        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
  spannableStringBuilder.setSpan(new ForegroundColorSpan(color), start, end, 0);
                textView.setText(spannableStringBuilder);

可跨越的字符串在不同的设备上给出不同的结果
