<强> Try This To Use Html.fromHtml() in all APIs ： -

     @SuppressWarnings("deprecation") 
       public static Spanned fromHtml(String html)
       { 
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        return Html.fromHtml(html, Html.FROM_HTML_MODE_LEGACY); 
        } else{ 
        return Html.fromHtml(html);
       }

使用它与标志参数
的 Flag Parameters Are ： -

public static final int FROM_HTML_MODE_COMPACT = 63; public static final int FROM_HTML_MODE_LEGACY = 0; public static final int FROM_HTML_OPTION_USE_CSS_COLORS = 256; public static final int FROM_HTML_SEPARATOR_LINE_BREAK_BLOCKQUOTE = 32; public static final int FROM_HTML_SEPARATOR_LINE_BREAK_DIV = 16; public static final int FROM_HTML_SEPARATOR_LINE_BREAK_HEADING = 2; public static final int FROM_HTML_SEPARATOR_LINE_BREAK_LIST = 8; public static final int FROM_HTML_SEPARATOR_LINE_BREAK_LIST_ITEM = 4; public static final int FROM_HTML_SEPARATOR_LINE_BREAK_PARAGRAPH = 1; public static final int TO_HTML_PARAGRAPH_LINES_CONSECUTIVE = 0; public static final int TO_HTML_PARAGRAPH_LINES_INDIVIDUAL = 1;

Answer 2

试试这个

    String errorString = "This field cannot be empty";  // Your custom error message.
    ForegroundColorSpan foregroundColorSpan = new ForegroundColorSpan(errorColor);
    SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder(errorString);
    spannableStringBuilder.setSpan(foregroundColorSpan, 0, errorString.length(), 0);
    editTextView.setError(spannableStringBuilder);

更改editText字段的setError方法的文本颜色
