我编写了一个例子来解决你的问题在Kotlin。

这是准则:

    val completeText = getString(R.string.terms_description)
    val textToFind = getString(R.string.show_terms)
    val spannableString: Spannable = SpannableString(completeText)
    val startFocus = completeText.indexOf(textToFind)
    val endFocus = startFocus + textToFind.length

    spannableString.setSpan(object: ClickableSpan() {
        override fun onClick(p0: View) {
            showMessage()
        }
    }, startFocus, endFocus, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
    show_terms.text = spannableString
    show_terms.movementMethod = LinkMovementMethod.getInstance();
    show_terms.highlightColor = Color.TRANSPARENT;

这是XML

    <CheckBox
            android:id="@+id/check_agree_terms"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>

    <TextView
            android:id="@+id/show_terms"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textColorLink="@color/colorPrimary"
            android:layout_toEndOf="@id/check_agree_terms"/>

这就是它的样子

在这里输入图像描述

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);

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());


}

Kotlin上复杂但通用的解决方案

  /*
    * Receive Pair of Text and Action and set it clickable and appearing as link
    * */
fun TextView.setClickableText(vararg textToSpanAndClickAction: Pair<String, (String) -> Unit>) {
    val builder = SpannableStringBuilder(text.toString())

    textToSpanAndClickAction.forEach { argPair ->
    val clickableSpan = object : ClickableSpan() {
        override fun onClick(widget: View) {
            argPair.second.invoke(argPair.first)
        }
    }

    this.text.toString().let { fullText ->
        val indexOfFirst = fullText.indexOf(argPair.first)
        val indexOfLast = indexOfFirst + argPair.first.length
        if (indexOfFirst < 0){
            //No match found
            return
        }else{
            builder.setSpan(
                clickableSpan,
                indexOfFirst,
                indexOfLast,
                Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
            )
        }
    }
}

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

Kotlin Spannable

大胆的,

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

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);

}
