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

这是一个帮助函数。当你有多种语言的时候非常有用!

private void setColor(TextView view, String fulltext, String subtext, int color) {
    view.setText(fulltext, TextView.BufferType.SPANNABLE);
    Spannable str = (Spannable) view.getText();
    int i = fulltext.indexOf(subtext);
    str.setSpan(new ForegroundColorSpan(color), i, i + subtext.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}

create textview in ur layout paste this code in ur MainActivity TextView textview=(TextView)findViewById(R.id.textviewid); Spannable spannable=new SpannableString("Hello my name is sunil"); spannable.setSpan(new ForegroundColorSpan(Color.BLUE), 0, 5, Spannable.SPAN_INCLUSIVE_EXCLUSIVE); textview.setText(spannable); //Note:- the 0,5 is the size of colour which u want to give the strring //0,5 means it give colour to starting from h and ending with space i.e.(hello), if you want to change size and colour u can easily

只是补充一个公认的答案，因为所有的答案似乎都在谈论android.graphics.Color only:如果我想要的颜色是在res/values/colors.xml中定义的呢?

例如，考虑colors.xml中定义的材质设计颜色:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="md_blue_500">#2196F3</color>
</resources>

(android_material_design_colors .xml是你最好的朋友)

然后使用contextcompast . getcolor (getContext()， R.color.md_blue_500)，在这里您将使用Color。蓝色，所以:

wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

就变成:

wordtoSpan.setSpan(new ForegroundColorSpan(ContextCompat.getColor(getContext(), R.color.md_blue_500)), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

我发现:

在Android中使用跨度- Michael Spitsin - Medium

这里有些答案不是最新的。因为，您将(在大多数情况下)在链接上添加一个自定义的clic操作。

此外，正如文档帮助所提供的，您的跨接字符串链接颜色将有一个默认颜色。 默认的链接颜色是主题的强调色或android:textColorLink(如果这个属性是在主题中定义的)。

这里有一种安全的方法。

 private class CustomClickableSpan extends ClickableSpan {

    private int color = -1;

    public CustomClickableSpan(){
        super();
        if(getContext() != null) {
            color = ContextCompat.getColor(getContext(), R.color.colorPrimaryDark);
        }
    }

    @Override
    public void updateDrawState(@NonNull TextPaint ds) {
        ds.setColor(color != -1 ? color : ds.linkColor);
        ds.setUnderlineText(true);
    }

    @Override
    public void onClick(@NonNull View widget) {
    }
}

然后使用它。

   String text = "my text with action";
    hideText= new SpannableString(text);
    hideText.setSpan(new CustomClickableSpan(){

        @Override
        public void onClick(@NonNull View widget) {
            // your action here !
        }

    }, 0, text.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    yourtextview.setText(hideText);
    // don't forget this ! or this will not work !
    yourtextview.setMovementMethod(LinkMovementMethod.getInstance());

希望这对你有很大帮助!
