我也有同样的问题。 @Dano的回答绝对正确。但这对我没用。 之后，我发现问题，我已经添加ClickableSpan。它会把我的颜色改成另一种颜色(强调色)

问题

当你在ForegroundColorSpan或UnderlineSpan后添加ClickableSpan时，SpannableStringBuilder将不会改变颜色和undline。

解决方案

1. 与ClickableSpan

你可以覆盖ClickableSpan内部的updateDrawState方法。 在updateDrawState方法中，您应该删除超级回调。 之后，你应该根据需要修改你的文本绘制。

2. 没有ClickableSpan

添加ForegroundColorSpan来改变文本颜色 Add UnderlineSpan在文本中添加下划线。

使用kotlin-ktx，您可以轻松实现这一点

        bindView?.oneTimePasswordTitle?.text = buildSpannedString {
        append("One Time Password ")
        inSpans(
            ForegroundColorSpan(ContextCompat.getColor(bindView?.oneTimePasswordTitle?.context!!,R.color.colorPrimaryText))
        ){
            append(" (As Registered Email)")
        }

    }

设置你的TextView的文本跨度，并为你的文本定义一个ForegroundColorSpan。

TextView textView = (TextView)findViewById(R.id.mytextview01);    
Spannable wordtoSpan = new SpannableString("I know just how to whisper, And I know just how to cry,I know just where to find the answers");          
wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);    
textView.setText(wordtoSpan);

create textview in ur layout paste this code in ur MainActivity TextView textview=(TextView)findViewById(R.id.textviewid); Spannable spannable=new SpannableString("Hello my name is sunil"); spannable.setSpan(new ForegroundColorSpan(Color.BLUE), 0, 5, Spannable.SPAN_INCLUSIVE_EXCLUSIVE); textview.setText(spannable); //Note:- the 0,5 is the size of colour which u want to give the strring //0,5 means it give colour to starting from h and ending with space i.e.(hello), if you want to change size and colour u can easily

String text = "I don't like Hasina.";
textView.setText(spannableString(text, 8, 14));

private SpannableString spannableString(String text, int start, int end) {
    SpannableString spannableString = new SpannableString(text);
    ColorStateList redColor = new ColorStateList(new int[][]{new int[]{}}, new int[]{0xffa10901});
    TextAppearanceSpan highlightSpan = new TextAppearanceSpan(null, Typeface.BOLD, -1, redColor, null);

    spannableString.setSpan(highlightSpan, start, end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    spannableString.setSpan(new BackgroundColorSpan(0xFFFCFF48), start, end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    spannableString.setSpan(new RelativeSizeSpan(1.5f), start, end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

    return spannableString;
}

输出:

如果你想要更多的控制，你可能想检查TextPaint类。下面是如何使用它:

final ClickableSpan clickableSpan = new ClickableSpan() {
    @Override
    public void onClick(final View textView) {
        //Your onClick code here
    }

    @Override
    public void updateDrawState(final TextPaint textPaint) {
        textPaint.setColor(yourContext.getResources().getColor(R.color.orange));
        textPaint.setUnderlineText(true);
    }
};
