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());

kotlin中更通用的答案

   fun setClickableText(view: TextView, firstSpan: String, secondSpan: String) {
    val context = view.context
    val builder = SpannableStringBuilder()
    val unClickableSpan = SpannableString(firstSpan)
    val span = SpannableString(" "+secondSpan)

    builder.append(unClickableSpan);
    val clickableSpan: ClickableSpan = object : ClickableSpan() {
        override fun onClick(textView: View) {
            val intent = Intent(context, HomeActivity::class.java)
         context.startActivity(intent)
        }

        override fun updateDrawState(ds: TextPaint) {
            super.updateDrawState(ds)
            ds.isUnderlineText = true
            ds.setTypeface(Typeface.create(Typeface.DEFAULT, Typeface.ITALIC));
        }
    }
    builder.append(span);
    builder.setSpan(clickableSpan, firstSpan.length, firstSpan.length+secondSpan.length+1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)

    view.setText(builder,TextView.BufferType.SPANNABLE)
    view.setMovementMethod(LinkMovementMethod.getInstance());


}

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))
    }))

Phan Van Linh回答的版本。

请注意它有一些小的改动。

fun makeLinks(textView: TextView, links: Array<String>, clickableSpans: Array<ClickableSpan>) {
    val spannableString = SpannableString(textView.text)

    for (i in links.indices) {
        val clickableSpan = clickableSpans[i]
        val link = links[i]

        val startIndexOfLink = textView.text.indexOf(link)

        spannableString.setSpan(clickableSpan, startIndexOfLink, startIndexOfLink + link.length,
                Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
    }

    textView.movementMethod = LinkMovementMethod.getInstance()
    textView.setText(spannableString, TextView.BufferType.SPANNABLE)
}

fun setupClickableTextView() {
    val termsOfServicesClick = object : ClickableSpan() {
        override fun onClick(p0: View?) {
            Toast.makeText(applicationContext, "ToS clicked", Toast.LENGTH_SHORT).show()
        }
    }

    val privacyPolicyClick = object : ClickableSpan() {
        override fun onClick(p0: View?) {
            Toast.makeText(applicationContext, "PP clicked", Toast.LENGTH_SHORT).show()
        }
    }

    makeLinks(termsTextView, arrayOf("terms", "privacy policy"), arrayOf(termsOfServicesClick, privacyPolicyClick))
}

大胆的,

mySpannable.setSpan(new StyleSpan(Typeface.BOLD),termStart,termStop,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

这里有一个Kotlin解决方案，与本地化工作得更好:

data class LinkedText(@StringRes val textRes: Int, val clickListener: View.OnClickListener? = null)

fun TextView.setPartiallyLinkedText(vararg texts: LinkedText) {
    this.text = texts.joinToString(" ") { context.getString(it.textRes) }
    val spannableString = SpannableString(this.text)
    var startIndexOfLink = -1
    texts.forEach { text ->
        val string = context.getString(text.textRes)
        if (text.clickListener != null) {
            val clickableSpan = object : ClickableSpan() {
                override fun updateDrawState(textPaint: TextPaint) {
                    textPaint.color = textPaint.linkColor
                    textPaint.isUnderlineText = true
                }
                override fun onClick(view: View) {
                    Selection.setSelection((view as TextView).text as Spannable, 0)
                    view.invalidate()
                    text.clickListener.onClick(view)
                }
            }
            startIndexOfLink = this.text.toString().indexOf(string, startIndexOfLink + 1)
            spannableString.setSpan(
                clickableSpan, startIndexOfLink, startIndexOfLink + string.length,
                Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
            )
        }
    }
    this.movementMethod = LinkMovementMethod.getInstance()
    this.setText(spannableString, TextView.BufferType.SPANNABLE)
}

像这样使用它:

textView.setPartiallyLinkedText(
    LinkedText(R.string.not_linked_text),
    LinkedText(R.string.linked_text) {
        Toast.makeText(context, "You clicked", Toast.LENGTH_LONG).show()
    },
)
