创建优雅的Kotlin方式与扩展:

fun TextView.setClickableText(text: Spanned,
                              clickableText: String,
                              @ColorInt clickableColor: Int,
                              clickListener: () -> Unit) {
    val spannableString = SpannableString(text)

    val startingPosition: Int = text.indexOf(clickableText)

    if (startingPosition > -1) {
        val clickableSpan: ClickableSpan = object : ClickableSpan() {
            override fun onClick(textView: View) {
                clickListener()
            }

            override fun updateDrawState(textPaint: TextPaint) {
                super.updateDrawState(textPaint)
                textPaint.isUnderlineText = false
            }
        }

        val endingPosition: Int = startingPosition + clickableText.length
        spannableString.setSpan(clickableSpan, startingPosition,
                endingPosition, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
        spannableString.setSpan(ForegroundColorSpan(clickableColor), startingPosition,
                endingPosition, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
        movementMethod = LinkMovementMethod.getInstance()
        highlightColor = Color.TRANSPARENT
    }

    setText(spannableString)
}

这是java爱好者的Boom Check:D 我们可以根据自己的需要进行修改:

List<Pair<String, View.OnClickListener>> pairsList = new ArrayList<>();

        pairsList.add(new Pair<>("38,50", v -> {
            Intent intent = new Intent(SignUpActivity.this, WebActivity.class);
            intent.putExtra("which", "tos");
            startActivity(intent);
        }));

        pairsList.add(new Pair<>("81,95", v -> {
            Intent intent = new Intent(SignUpActivity.this, WebActivity.class);
            intent.putExtra("which", "policy");
            startActivity(intent);
        }));

        makeLinks(pairsList); // Method calling


private void makeLinks(List<Pair<String, View.OnClickListener>> pairsList) {

        SpannableString ss = new SpannableString(By signing up, I’m agree to PAKRISM’s Terms of Use and confirms that I have read Privacy Policy);

        for (Pair<String, View.OnClickListener> pair : pairsList) {

            ClickableSpan clickableSpan = new ClickableSpan() {
                @Override
                public void onClick(View textView) {
                    //Toast.makeText(MyApplication.getAppContext(), "Clicked!", Toast.LENGTH_SHORT).show();
                    pair.second.onClick(textView);
                }

                @Override
                public void updateDrawState(TextPaint ds) {

                    ds.linkColor = ContextCompat.getColor(SignUpActivity.this, R.color.primary_main);
                    ds.setUnderlineText(true);

                    super.updateDrawState(ds);
                }
            };

            String[] indexes = pair.first.split(",");
            ss.setSpan(clickableSpan, Integer.parseInt(indexes[0]), Integer.parseInt(indexes[1]), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
        
        TextView tv = findViewById(R.id.txtView);
        tv.setText(ss);
        tv.setMovementMethod(LinkMovementMethod.getInstance());
    }

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());

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);

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()
}
