我做了这个helper方法，以防有人需要从字符串中开始和结束位置。

public static TextView createLink(TextView targetTextView, String completeString,
    String partToClick, ClickableSpan clickableAction) {

    SpannableString spannableString = new SpannableString(completeString);

    // make sure the String is exist, if it doesn't exist
    // it will throw IndexOutOfBoundException
    int startPosition = completeString.indexOf(partToClick);
    int endPosition = completeString.lastIndexOf(partToClick) + partToClick.length();

    spannableString.setSpan(clickableAction, startPosition, endPosition,
        Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

    targetTextView.setText(spannableString);
    targetTextView.setMovementMethod(LinkMovementMethod.getInstance());

    return targetTextView;
}

下面是你如何使用它

private void initSignUp() {
    String completeString = "New to Reddit? Sign up here.";
    String partToClick = "Sign up";
    ClickableTextUtil
        .createLink(signUpEditText, completeString, partToClick,
            new ClickableSpan() {
                @Override
                public void onClick(View widget) {
                    // your action
                    Toast.makeText(activity, "Start Sign up activity",
                        Toast.LENGTH_SHORT).show();
                }

                @Override
                public void updateDrawState(TextPaint ds) {
                    super.updateDrawState(ds);
                    // this is where you set link color, underline, typeface etc.
                    int linkColor = ContextCompat.getColor(activity, R.color.blumine);
                    ds.setColor(linkColor);
                    ds.setUnderlineText(false);
                }
            });
}

我的功能使TextView内的多个链接 更新2020:现在这个函数能够支持多个相同的文本链接在1 TextView，但记得把链接在正确的顺序

fun TextView.makeLinks(vararg links: Pair<String, View.OnClickListener>) {
    val spannableString = SpannableString(this.text)
    var startIndexOfLink = -1
    for (link in links) {
        val clickableSpan = object : ClickableSpan() {
            override fun updateDrawState(textPaint: TextPaint) {
                // use this to change the link color
                textPaint.color = textPaint.linkColor
                // toggle below value to enable/disable
                // the underline shown below the clickable text
                textPaint.isUnderlineText = true
            }

            override fun onClick(view: View) {
                Selection.setSelection((view as TextView).text as Spannable, 0)
                view.invalidate()
                link.second.onClick(view)
            }
        }
        startIndexOfLink = this.text.toString().indexOf(link.first, startIndexOfLink + 1)
//      if(startIndexOfLink == -1) continue // todo if you want to verify your texts contains links text
        spannableString.setSpan(
            clickableSpan, startIndexOfLink, startIndexOfLink + link.first.length,
            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
        )
    }
    this.movementMethod =
        LinkMovementMethod.getInstance() // without LinkMovementMethod, link can not click
    this.setText(spannableString, TextView.BufferType.SPANNABLE)
}

使用

my_text_view.makeLinks(
        Pair("Terms of Service", View.OnClickListener {
            Toast.makeText(applicationContext, "Terms of Service Clicked", Toast.LENGTH_SHORT).show()
        }),
        Pair("Privacy Policy", View.OnClickListener {
            Toast.makeText(applicationContext, "Privacy Policy Clicked", Toast.LENGTH_SHORT).show()
        }))

XML

<TextView
    android:id="@+id/my_text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Please accept Terms of Service and Privacy Policy"
    android:textColorHighlight="#f00" // background color when pressed
    android:textColorLink="#0f0"
    android:textSize="20sp" />

对于kotlin使用这个扩展

fun TextView.makeLinks(vararg links: Pair<String, View.OnClickListener>) {
val spannableString = SpannableString(this.text)
for (link in links) {
    val clickableSpan = object : ClickableSpan() {
        override fun onClick(view: View) {
            Selection.setSelection((view as TextView).text as Spannable, 0)
            view.invalidate()
            link.second.onClick(view)
        }
    }
    val startIndexOfLink = this.text.toString().indexOf(link.first)
    spannableString.setSpan(
        clickableSpan, startIndexOfLink, startIndexOfLink + link.first.length,
        Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
    )
    spannableString.setSpan(
        ForegroundColorSpan(Color.parseColor("#46C2CC")),
        startIndexOfLink,
        startIndexOfLink + link.first.length,
        Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
    )
}
this.movementMethod =
    LinkMovementMethod.getInstance() // without LinkMovementMethod, link can not click
this.setText(spannableString, TextView.BufferType.SPANNABLE)

}

像这样调用它

binding.agreeText.makeLinks(Pair(getString(R.string.terms_conditionsClick),View.OnClickListener {
        startActivity(TermsAndConditionActivity.getIntent(this))
    }))

它对文本的某些部分的可点击部分非常有帮助。

点是正则表达式中的一个特殊字符。如果你想要分隔圆点，需要将圆点转义为\\。而不是仅仅将"."传递给可扩展的文本方法。或者，也可以使用正则表达式[。在Java中通过一个点来分隔字符串。

android.text.style.ClickableSpan可以解决你的问题。

SpannableString ss = new SpannableString("Android is a Software stack");
ClickableSpan clickableSpan = new ClickableSpan() {
    @Override
    public void onClick(View textView) {
        startActivity(new Intent(MyActivity.this, NextActivity.class));
    }
    @Override
    public void updateDrawState(TextPaint ds) {
        super.updateDrawState(ds);
        ds.setUnderlineText(false);
    }
};
ss.setSpan(clickableSpan, 22, 27, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

TextView textView = (TextView) findViewById(R.id.hello);
textView.setText(ss);
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setHighlightColor(Color.TRANSPARENT);

在XML:

<TextView 
  ...
  android:textColorLink="@drawable/your_selector"
/>

提供的解决方案相当不错。然而，我通常使用更简单的解决方案。

这是一个linkify效用函数

/**
 * Method is used to Linkify words in a TextView
 *
 * @param textView TextView who's text you want to change
 * @param textToLink The text to turn into a link
 * @param url   The url you want to send the user to
 */
fun linkify(textView: TextView, textToLink: String, url: String) {
    val pattern = Pattern.compile(textToLink)
    Linkify.addLinks(textView, pattern, url, { _, _, _ -> true })
    { _, _ -> "" }
}

使用这个函数非常简单。这里有一个例子

    // terms and privacy
    val tvTerms = findViewById<TextView>(R.id.tv_terms)
    val tvPrivacy = findViewById<TextView>(R.id.tv_privacy)
    Utils.linkify(tvTerms, resources.getString(R.string.terms),
            Constants.TERMS_URL)
    Utils.linkify(tvPrivacy, resources.getString(R.string.privacy),
            Constants.PRIVACY_URL)
