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

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" />

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()
    },
)

它对文本的某些部分的可点击部分非常有帮助。

点是正则表达式中的一个特殊字符。如果你想要分隔圆点，需要将圆点转义为\\。而不是仅仅将"."传递给可扩展的文本方法。或者，也可以使用正则表达式[。在Java中通过一个点来分隔字符串。

 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());
