芬兰湾的科特林:

@JvmStatic
    @BindingAdapter(
        "app:txt1",
        "app:txt2",
        "app:color1",
        "app:color2",
        requireAll = false
    )
    fun setColors(
        txtView: AppCompatTextView,
        txt1: String,
        txt2: String,
        color1: Int,
        color2: Int
    ) {
        txtView.setColors(txt1 = txt1, txt2 = txt2, color1 = color1, color2)
    }


fun AppCompatTextView.setColors(txt1: String, txt2: String, color1: Int, color2: Int) {


        val word: Spannable = SpannableString(txt1)

        word.setSpan(
            ForegroundColorSpan(ContextCompat.getColor(this.context, color1)),
            0,
            word.length,
            Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
        )

        this.text = word
        val wordTwo: Spannable = SpannableString(txt2)

        wordTwo.setSpan(
            ForegroundColorSpan(ContextCompat.getColor(this.context, color2)),
            0,
            wordTwo.length,
            Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
        )
        this.append(wordTwo)

    }


<androidx.appcompat.widget.AppCompatTextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:txt1="@{}"
            app:txt2="@{}"
            app:color1="@{}"
            app:color2="@{}" />

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);

你可以在没有HTML的情况下打印多种颜色的行:

TextView textView = (TextView) findViewById(R.id.mytextview01);
Spannable word = new SpannableString("Your message");        

word.setSpan(new ForegroundColorSpan(Color.BLUE), 0, word.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

textView.setText(word);
Spannable wordTwo = new SpannableString("Your new message");        

wordTwo.setSpan(new ForegroundColorSpan(Color.RED), 0, wordTwo.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.append(wordTwo);

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!

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)

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)
