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

如果你想要更多的控制，你可能想检查TextPaint类。下面是如何使用它:

final ClickableSpan clickableSpan = new ClickableSpan() {
    @Override
    public void onClick(final View textView) {
        //Your onClick code here
    }

    @Override
    public void updateDrawState(final TextPaint textPaint) {
        textPaint.setColor(yourContext.getResources().getColor(R.color.orange));
        textPaint.setUnderlineText(true);
    }
};

    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);

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);

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);
