我是这样做的:

通过传递String和Color在文本上设置颜色:

private String getColoredSpanned(String text, String color) {
    String input = "<font color=" + color + ">" + text + "</font>";
    return input;
}

通过调用下面的代码设置TextView / Button / EditText等文本:

TextView:

TextView txtView = (TextView)findViewById(R.id.txtView);

获取彩色字符串:

String name = getColoredSpanned("Hiren", "#800000");
String surName = getColoredSpanned("Patel","#000080");

在TextView上设置两个不同颜色的字符串的文本:

txtView.setText(Html.fromHtml(name+" "+surName));

Done

尽可能使用SpannableBuilder类而不是HTML格式，因为它比HTML格式解析更快。 在Github上查看我自己的基准测试“SpannableBuilder vs HTML” 谢谢!

是的，如果你用html的font-color属性格式化字符串，然后把它传递给方法html . fromhtml(你的文本在这里)

String text = "<font color=#cc0029>First Color</font> <font color=#ffcc00>Second Color</font>";
yourtextview.setText(Html.fromHtml(text));

fun setTextColor(tv:TextView, startPosition:Int, endPosition:Int, color:Int){
    val spannableStr = SpannableString(tv.text)

    val underlineSpan = UnderlineSpan()
    spannableStr.setSpan(
        underlineSpan,
        startPosition,
        endPosition,
        Spanned.SPAN_INCLUSIVE_EXCLUSIVE
    )

    val backgroundColorSpan = ForegroundColorSpan(this.resources.getColor(R.color.agreement_color))
    spannableStr.setSpan(
        backgroundColorSpan,
        startPosition,
        endPosition,
        Spanned.SPAN_INCLUSIVE_EXCLUSIVE
    )

    val styleSpanItalic = StyleSpan(Typeface.BOLD)
    spannableStr.setSpan(
        styleSpanItalic,
        startPosition,
        endPosition,
        Spanned.SPAN_INCLUSIVE_EXCLUSIVE
    )

    tv.text = spannableStr
}

之后，调用上述函数。你可以拨打多个电话:

setTextColor(textView, 0, 61, R.color.agreement_color)
setTextColor(textView, 65, 75, R.color.colorPrimary)

输出: 你可以看到下划线和不同的颜色。

试试这个:

mBox = new TextView(context);
mBox.setText(Html.fromHtml("<b>" + title + "</b>" +  "<br />" + 
      "<small>" + description + "</small>" + "<br />" + 
      "<small>" + DateAdded + "</small>"));

使用SpannableStringBuilder

SpannableStringBuilder builder = new SpannableStringBuilder();

SpannableString str1= new SpannableString("Text1");
str1.setSpan(new ForegroundColorSpan(Color.RED), 0, str1.length(), 0);
builder.append(str1);

SpannableString str2= new SpannableString(appMode.toString());
str2.setSpan(new ForegroundColorSpan(Color.GREEN), 0, str2.length(), 0);
builder.append(str2);

TextView tv = (TextView) view.findViewById(android.R.id.text1);
tv.setText( builder, TextView.BufferType.SPANNABLE);
