您可以使用示例代码。您希望了解关于ClickableSpan的详细信息。请检查这份文件

  SpannableString myString = new SpannableString("This is example");
            
            ClickableSpan clickableSpan = new ClickableSpan() {
                    @Override
                    public void onClick(View textView) {
                        ToastUtil.show(getContext(),"Clicked Smile ");
                    }
                };
        
        //For Click
         myString.setSpan(clickableSpan,startIndex,lastIndex,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        
        //For UnderLine
         myString.setSpan(new UnderlineSpan(),startIndex,lastIndex,0);
        
        //For Bold
        myString.setSpan(new StyleSpan(Typeface.BOLD),startIndex,lastIndex,0);
        
        //Finally you can set to textView. 
        
        TextView textView = (TextView) findViewById(R.id.txtSpan);
        textView.setText(myString);
        textView.setMovementMethod(LinkMovementMethod.getInstance());

您可以使用此方法设置可点击的值

public void setClickableString(String clickableValue, String wholeValue, TextView yourTextView){
    String value = wholeValue;
    SpannableString spannableString = new SpannableString(value);
    int startIndex = value.indexOf(clickableValue);
    int endIndex = startIndex + clickableValue.length();
    spannableString.setSpan(new ClickableSpan() {
                                @Override
                                public void updateDrawState(TextPaint ds) {
                                    super.updateDrawState(ds);
                                    ds.setUnderlineText(false); // <-- this will remove automatic underline in set span
                                }

                                @Override
                                public void onClick(View widget) {
                                    // do what you want with clickable value
                                }
                            }, startIndex, endIndex, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    yourTextView.setText(spannableString);
    yourTextView.setMovementMethod(LinkMovementMethod.getInstance()); // <-- important, onClick in ClickableSpan won't work without this
}

下面是如何使用它:

TextView myTextView = findViewById(R.id.myTextView);
setClickableString("stack", "Android is a Software stack", myTextView);

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。

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)

你可以像本文中描述的那样使用ClickableSpan

示例代码:

TextView myTextView = new TextView(this);
String myString = "Some text [clickable]";
int i1 = myString.indexOf("[");
int i2 = myString.indexOf("]");
myTextView.setMovementMethod(LinkMovementMethod.getInstance());
myTextView.setText(myString, BufferType.SPANNABLE);
Spannable mySpannable = (Spannable)myTextView.getText();
ClickableSpan myClickableSpan = new ClickableSpan() {
   @Override
   public void onClick(View widget) { /* do something */ }
};
mySpannable.setSpan(myClickableSpan, i1, i2 + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

参考

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))
    }))
