你可以使用Spannable应用效果到你的TextView:

这是我的例子，只是一个TextView文本的第一部分上色(同时允许您动态设置颜色，而不是硬编码成字符串与HTML的例子!)

    mTextView.setText("Red text is here", BufferType.SPANNABLE);
    Spannable span = (Spannable) mTextView.getText();
    span.setSpan(new ForegroundColorSpan(0xFFFF0000), 0, "Red".length(),
             Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

在这个例子中，你可以将0xFFFF0000替换为getResources().getColor(R.color.red)

试试这个:

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

最好使用strings文件中的字符串，如下所示:

    <string name="some_text">
<![CDATA[
normal color <font color=\'#06a7eb\'>special color</font>]]>
    </string>

用法:

textView.text=HtmlCompat.fromHtml(getString(R.string.some_text), HtmlCompat.FROM_HTML_MODE_LEGACY)

很棒的答案!我能够使用Spannable构建彩虹色的文本(所以这可以重复为任何颜色的数组)。这是我的方法，如果它能帮助到任何人的话:

private Spannable buildRainbowText(String pack_name) {
        int[] colors = new int[]{Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE, Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE, Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE, Color.RED, 0xFFFF9933, Color.YELLOW, Color.GREEN, Color.BLUE};
        Spannable word = new SpannableString(pack_name);
        for(int i = 0; i < word.length(); i++) {
            word.setSpan(new ForegroundColorSpan(colors[i]), i, i+1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
        return word;
    }

然后我只是setText(buildRainboxText(pack_name)); 注意，我传入的所有单词都在15个字符以下，这只是重复5种颜色3次-你需要根据你的使用调整数组的颜色/长度!

@Swapnil Kotwal回答的Kotlin版本。

Android Studio 4.0.1, Kotlin 1.3.72

val greenText = SpannableString("This is green,")
greenText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someGreenColor), null), 0, greenText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
yourTextView.text = greenText

val yellowText = SpannableString("this is yellow, ")
yellowText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someYellowColor), null), 0, yellowText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
yourTextView.append(yellowText)

val redText = SpannableString("and this is red.")
redText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someRedColor), null), 0, redText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
yourTextView.append(redText)

让普通函数转换你的字符串是可扩展的，像这样。

//pass param textviewid ,start,end,string
//R.color.Red it's your color you can change it as requirement

fun SpannableStringWithColor(view: TextView,start:Int,end:Int, s: String) {
    val wordtoSpan: Spannable =
        SpannableString(s)
    wordtoSpan.setSpan(
        ForegroundColorSpan(ContextCompat.getColor(view.context, R.color.Red)),
        start,
        end,
        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
    )
    view.text = wordtoSpan
    }

像这样的要求我们可以在任何地方使用。

 SpannableStringWithColor(tvMobileNo,0,14,"Mobile Number :   " + "123456789")

 SpannableStringWithColor(tvEmail,0,5,"Email :   " + "abc@gmail.com" "))

 SpannableStringWithColor(tvAddress,0,8,"Address :   " + "Delhi India")
