我会建议一种不同的方法，我认为这种方法需要更少的代码，而且更“本地化友好”。

假设你的目标活动被称为“ActivityStack”，在manifest中定义一个意图过滤器，使用一个自定义的方案(例如。“myappscheme”)

<activity
    android:name=".ActivityStack">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:host="stack"/>
        <data android:scheme="myappscheme" />
    </intent-filter>
</activity>

定义没有任何特殊标签的TextView(重要的是不要使用"android:autoLink"标签，参见:https://stackoverflow.com/a/20647011/1699702):

<TextView
    android:id="@+id/stackView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/stack_string" />

然后在TextView的文本中使用带有自定义方案和主机的链接作为(在String.xml中):

<string name="stack_string">Android is a Software <a href="myappscheme://stack">stack</a></string>

和“激活”与setMovementMethod()(在onCreate()的活动或onCreateView()的片段链接):

TextView stack = findViewById(R.id.stackView);
stack.setMovementMethod(LinkMovementMethod.getInstance());

这将通过点击“stack”字打开堆栈活动。

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)
}

这是一个Kotlin方法，使TextView的部分可点击:

private fun makeTextLink(textView: TextView, str: String, underlined: Boolean, color: Int?, action: (() -> Unit)? = null) {
    val spannableString = SpannableString(textView.text)
    val textColor = color ?: textView.currentTextColor
    val clickableSpan = object : ClickableSpan() {
        override fun onClick(textView: View) {
            action?.invoke()
        }
        override fun updateDrawState(drawState: TextPaint) {
            super.updateDrawState(drawState)
            drawState.isUnderlineText = underlined
            drawState.color = textColor
        }
    }
    val index = spannableString.indexOf(str)
    spannableString.setSpan(clickableSpan, index, index + str.length, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
    textView.text = spannableString
    textView.movementMethod = LinkMovementMethod.getInstance()
    textView.highlightColor = Color.TRANSPARENT
}

它可以被多次调用，在TextView中创建几个链接:

makeTextLink(myTextView, str, false, Color.RED, action = { Log.d("onClick", "link") })
makeTextLink(myTextView, str1, true, null, action = { Log.d("onClick", "link1") })

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);

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);
                }
            });
}

Phan Van Linh回答的版本。

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))
}
