在某些情况下可以使用的另一种方法是在接受Spannable的视图的属性中设置链接颜色。

例如，如果你的Spannable将用于TextView，你可以在XML中设置链接颜色:

<TextView
    android:id="@+id/myTextView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textColorLink="@color/your_color"
</TextView>

你也可以在代码中使用:

TextView tv = (TextView) findViewById(R.id.myTextView);
tv.setLinkTextColor(your_color);

有一个用于创建Spannable的工厂，并避免强制转换，就像这样:

Spannable span = Spannable.Factory.getInstance().newSpannable("text");

从开发人员文档中，更改一个可伸缩对象的颜色和大小:

1-创建类:

    class RelativeSizeColorSpan(size: Float,@ColorInt private val color: Int): RelativeSizeSpan(size) {

    override fun updateDrawState(textPaint: TextPaint?) {
        super.updateDrawState(textPaint)
        textPaint?.color = color
    } 
}

2 .使用该类创建你的spannable:

    val spannable = SpannableStringBuilder(titleNames)
spannable.setSpan(
    RelativeSizeColorSpan(1.5f, Color.CYAN), // Increase size by 50%
    titleNames.length - microbe.name.length, // start
    titleNames.length, // end
    Spannable.SPAN_EXCLUSIVE_INCLUSIVE
)

下面的内容非常适合我

    tvPrivacyPolicy = (TextView) findViewById(R.id.tvPrivacyPolicy);
    String originalText = (String)tvPrivacyPolicy.getText();
    int startPosition = 15;
    int endPosition = 31;

    SpannableString spannableStr = new SpannableString(originalText);
    UnderlineSpan underlineSpan = new UnderlineSpan();
    spannableStr.setSpan(underlineSpan, startPosition, endPosition, Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

    ForegroundColorSpan backgroundColorSpan = new ForegroundColorSpan(Color.BLUE);
    spannableStr.setSpan(backgroundColorSpan, startPosition, endPosition, Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

    StyleSpan styleSpanItalic  = new StyleSpan(Typeface.BOLD);

    spannableStr.setSpan(styleSpanItalic, startPosition, endPosition, Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

    tvPrivacyPolicy.setText(spannableStr);

以上代码的输出

另一个答案将非常相似，但不需要设置TextView的文本两次

TextView TV = (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);

TV.setText(wordtoSpan);

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);
