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))
    }))

 t= (TextView) findViewById(R.id.PP1);

 t.setText(Html.fromHtml("<bThis is normal text </b>" +
                "<a href=\"http://www.xyz-zyyx.com\">This is cliclable text</a> "));
 t.setMovementMethod(LinkMovementMethod.getInstance());

这是一个kotlin扩展(不工作，如果文本重复)

textView.makeTextClickable(
    contentText = "Hello world",
    clickableText = "world",
    isBoldText = true,
    onClick = {
        openPageInBrowser(BuildConfig.PRIVACY_POLICY_URL)
    }
)



   internal fun TextView.makeTextClickable(
    contentText: String,
    clickableText: String,
    onClick: () -> Unit,
    isUnderlineText: Boolean = false,
    isBoldText: Boolean = false
) {
    val spannableString = SpannableString(contentText)

    val clickableSpan = object : ClickableSpan() {
        override fun onClick(widget: View) {
            onClick()
        }

        override fun updateDrawState(ds: TextPaint) {
            super.updateDrawState(ds)
            ds.isUnderlineText = isUnderlineText
            ds.isFakeBoldText = isBoldText
        }
    }

    val clickableTextStartIndex = text.indexOf(clickableText)
    val clickableTextEndIndex = clickableTextStartIndex + clickableText.length

    spannableString.setSpan(
        clickableSpan,
        clickableTextStartIndex,
        clickableTextEndIndex,
        Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
    )

    this.text = spannableString
    this.movementMethod = LinkMovementMethod.getInstance()
}

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

使用URLSpan类获取url

val spans: Array<URLSpan> = result.getSpans(0, result.length, URLSpan::class.java)

方法

fun TextView.createClickable(string: String, action:(String)->Unit ) {
      text = HtmlCompat.fromHtml(string, HtmlCompat.FROM_HTML_MODE_LEGACY)
      val result = SpannableString(text)
      val spans = result.getSpans(0, result.length, URLSpan::class.java)
      for (span in spans) {
          val link:Pair<String, View.OnClickListener> = Pair(span.url, View.OnClickListener {
              action(span.url)
          })
          val start = result.getSpanStart(span)
          val end = result.getSpanEnd(span)
          val flags = result.getSpanFlags(span)
          result.removeSpan(span)
          val clickableSpan: ClickableSpan = object : ClickableSpan() {
              override fun onClick(textView: View) {
                  textView.invalidate()
                  link.second.onClick(textView)
              }
              override fun updateDrawState(textPaint: TextPaint) {
                  super.updateDrawState(textPaint)
                  textPaint.isUnderlineText = false
              }
          }
          result.setSpan(clickableSpan, start, end, flags)
          this.movementMethod = LinkMovementMethod.getInstance()
          this.setText(result, TextView.BufferType.SPANNABLE)
      }
  }

Use

示例文本:Android是一个软件堆栈，它非常棒

包装你的可点击的文本内锚标签

比如:Android是一个软件<a href='https://example.com/stack'> Stack </a>和它' <a href='https://example.com/awesome'> Awesome </a>。

 val str = "Android is a Software <a href='https://example.com/stack'> Stack </a> and it' <a href='https://example.com/awesome'> Awesome </a>."

textView.createClickable(str) {
    when(it) {
        "https://example.com/stack"->{
  startActivity(Intent(this,StackActivity::class.java))
                  }
        "https://example.com/awesom"->{
            startActivity(Intent(this,AwesomeActivity::class.java))
        }
    }
}

对于那些正在寻找Kotlin解决方案的人来说，这里是对我有用的:

private fun setupTermsAndConditions() {
    val termsAndConditions = resources.getString(R.string.terms_and_conditions)
    val spannableString = SpannableString(termsAndConditions)
    val clickableSpan = object : ClickableSpan() {
        override fun onClick(widget: View) {
            if (checkForWifiAndMobileInternet()) {
                // binding.viewModel!!.openTermsAndConditions()
                showToast("Good, open the link!!!")

            } else {
                showToast("Cannot open this file because of internet connection!")
            }

        }

        override fun updateDrawState(textPaint : TextPaint) {
            super.updateDrawState(textPaint)
            textPaint.color = resources.getColor(R.color.colorGrey)
            textPaint.isFakeBoldText = true
        }
    }

    spannableString.setSpan(clickableSpan, 34, 86, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
    binding.tvTermsAndConditions.text = spannableString
    binding.tvTermsAndConditions.movementMethod = LinkMovementMethod.getInstance()
    binding.tvTermsAndConditions.setHighlightColor(Color.TRANSPARENT);

}
