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);

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="@{}" />

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)

我不知道，因为这是可能的，但你可以简单地添加<font> </font>到你的string.xml，这将自动改变每个文本的颜色。不需要添加任何额外的代码，如可扩展的文本等。

例子

<string name="my_formatted_text">
    <font color="#FF0707">THIS IS RED</font>
    <font color="#0B132B">AND NOW BLUE</font>
</string>

使用Kotlin和扩展，您可以添加彩色文本非常简单和干净:

创建一个TextViewExtensions文件。Kt和这个含量

fun TextView.append(string: String?, @ColorRes color: Int) {
    if (string == null || string.isEmpty()) {
        return
    }

    val spannable: Spannable = SpannableString(string)
    spannable.setSpan(
        ForegroundColorSpan(ContextCompat.getColor(context, color)),
        0,
        spannable.length,
        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
    )

    append(spannable)
}

现在很容易添加文本的颜色

textView.text = "" // Remove old text
textView.append("Red Text", R.color.colorAccent)
textView.append("White Text", android.R.color.white)

基本上与@Abdul Rizwan的答案相同，但使用Kotlin，扩展，一些验证和在扩展内部获得颜色。

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)
