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)
      }
  }

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))
        }
    }
}

我的功能使TextView内的多个链接 更新2020:现在这个函数能够支持多个相同的文本链接在1 TextView，但记得把链接在正确的顺序

fun TextView.makeLinks(vararg links: Pair<String, View.OnClickListener>) {
    val spannableString = SpannableString(this.text)
    var startIndexOfLink = -1
    for (link in links) {
        val clickableSpan = object : ClickableSpan() {
            override fun updateDrawState(textPaint: TextPaint) {
                // use this to change the link color
                textPaint.color = textPaint.linkColor
                // toggle below value to enable/disable
                // the underline shown below the clickable text
                textPaint.isUnderlineText = true
            }

            override fun onClick(view: View) {
                Selection.setSelection((view as TextView).text as Spannable, 0)
                view.invalidate()
                link.second.onClick(view)
            }
        }
        startIndexOfLink = this.text.toString().indexOf(link.first, startIndexOfLink + 1)
//      if(startIndexOfLink == -1) continue // todo if you want to verify your texts contains links text
        spannableString.setSpan(
            clickableSpan, 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)
}

使用

my_text_view.makeLinks(
        Pair("Terms of Service", View.OnClickListener {
            Toast.makeText(applicationContext, "Terms of Service Clicked", Toast.LENGTH_SHORT).show()
        }),
        Pair("Privacy Policy", View.OnClickListener {
            Toast.makeText(applicationContext, "Privacy Policy Clicked", Toast.LENGTH_SHORT).show()
        }))

XML

<TextView
    android:id="@+id/my_text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Please accept Terms of Service and Privacy Policy"
    android:textColorHighlight="#f00" // background color when pressed
    android:textColorLink="#0f0"
    android:textSize="20sp" />

解决方案清除链接高亮选择遵循https://stackoverflow.com/a/19445108/5381331

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);

}

 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());

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);
