我做了这个helper方法，以防有人需要从字符串中开始和结束位置。

public static TextView createLink(TextView targetTextView, String completeString,
    String partToClick, ClickableSpan clickableAction) {

    SpannableString spannableString = new SpannableString(completeString);

    // make sure the String is exist, if it doesn't exist
    // it will throw IndexOutOfBoundException
    int startPosition = completeString.indexOf(partToClick);
    int endPosition = completeString.lastIndexOf(partToClick) + partToClick.length();

    spannableString.setSpan(clickableAction, startPosition, endPosition,
        Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

    targetTextView.setText(spannableString);
    targetTextView.setMovementMethod(LinkMovementMethod.getInstance());

    return targetTextView;
}

下面是你如何使用它

private void initSignUp() {
    String completeString = "New to Reddit? Sign up here.";
    String partToClick = "Sign up";
    ClickableTextUtil
        .createLink(signUpEditText, completeString, partToClick,
            new ClickableSpan() {
                @Override
                public void onClick(View widget) {
                    // your action
                    Toast.makeText(activity, "Start Sign up activity",
                        Toast.LENGTH_SHORT).show();
                }

                @Override
                public void updateDrawState(TextPaint ds) {
                    super.updateDrawState(ds);
                    // this is where you set link color, underline, typeface etc.
                    int linkColor = ContextCompat.getColor(activity, R.color.blumine);
                    ds.setColor(linkColor);
                    ds.setUnderlineText(false);
                }
            });
}

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());


}

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" />

参考

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

 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());

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

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))
    }))
