Android 在某些手机上，使用Spanable字符串更改阿拉伯语发音符号的颜色不起作用

我使用此代码更改阿拉伯字母的颜色：

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);

                            }

                        }

List arabicV=Arrays.asList（“ؘ”、“ؙ”、“ؚ”、“ؐ”、“ؑ”、“ؒ”、“ؓ”、“ؔ”、“ؕ”、“ؖ”、“ؗ”、“ؗ”、“ؗ”等）ﹰﹰ","ﹲ","ﹴ","ﹸ","ﹼ","ﹾ",
"ٍ","ً","ُ","ِ","َ","ّ","ٓ","ٔ","ْ","ِ","َّ","َ","َْ","َ","ً","ٌ","َ","ُ","ٍ"
,"َ","ْ","ِ","ُ","ّ","ً");
对于（int j=0；j

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。如下所示：

是否有人知道如何解决此问题或任何其他替代方法？

我找到了我的答案，有一种方法可以在所有设备上实现：

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);
            }
