android - 使用可跨越字符串更改阿拉伯语变音符号颜色在某些手机上不起作用

Question

我使用这段代码来改变阿拉伯语变音符号的颜色:

List<String> arabicV = Arrays.asList("ؘ","ؙ","ؚ","ؐ","ؐؑ","ؒ","ؓ","ؔ","ؕ","ؖ","ؗ","ؗ","ﹰﹰ","ﹲ","ﹴ","ﹸ","ﹼ","ﹾ",
            "ٍ","ً","ُ","ِ","َ","ّ","ٓ","ٔ","ْ","ِ","َّ","َ","َْ","َ","ً","ٌ","َ","ُ","ٍ"
            ,"َ","ْ","ِ","ُ","ّ","ً");

    for (int j = 0; j < myString.length; j++) {
        if (arabicV.contains(myString.substring(j, j + 1))) {
             wordtoSpan.setSpan(new ForegroundColorSpan(Color.parseColor("#FF0000")),
                                        j, j+1 , Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

                            }

                        }

它在我的设备上运行良好，如下所示:

但在某些设备(如 LG-G5)上它不起作用。像这样:

有谁知道如何解决这个问题或任何其他替代方法？

我找到了我的答案，有一种方法可以让它在所有设备上都正确:

SpannedString result = new SpannedString("");
            for (int j=0;j<myString.length();j++){
                Spannable wordtoSpan = new SpannableString(myString.substring(j,j+1));
                if (arabicV.contains(myString.substring(j,j+1))) {
                    wordtoSpan.setSpan(new ForegroundColorSpan(Color.parseColor("#FF0000")),
                            0, 1, 0);

                }
                else
                {
                    wordtoSpan.setSpan(new ForegroundColorSpan(Color.parseColor( "#000000")),
                            0, 1, 0);
                }
                result = (SpannedString) TextUtils.concat(result,"",wordtoSpan);
            }
