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

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)
}

Java解决方案(更新2022年)

特点:

允许多个点击时，有重复的词。 可以为每个重复的单词量身定制特定的命令。

我以daler445的代码为基础，允许对重复的单词使用多个可单击的命令。

在Java课上:

public class MainActivity extends AppCompatActivity {
    SharedPreferences sp;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        sp = getSharedPreferences("MyUserPrefs", Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sp.edit();

        TextView fulltext = (TextView) findViewById(R.id.fulltext);

        //replace setText("") to setText("Android is a Software stack") for his case
        fulltext.setText("Search [1] this full [1] text with repeated strings. Search [2] Search [3] full [2] full [3]");

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

        //replace "Search" with "stack" for his case
        String stringtohyperlink = "Search";
        String stringtohyperlink2 = "full";

        links.add(new Pair<>(stringtohyperlink, new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String position = sp.getString("position","0");
                if (position.equals("1")) {
                    Toast.makeText(MainActivity.this, "Search 1 has been Clicked.", Toast.LENGTH_SHORT).show();
                    editor.putString("position","0");
                    editor.apply();
                }
                if (position.equals("2")) {
                    Toast.makeText(MainActivity.this, "Search 2 has been Clicked.", Toast.LENGTH_SHORT).show();
                    editor.putString("position","0");
                    editor.apply();
                }
                if (position.equals("3")) {
                    Toast.makeText(MainActivity.this, "Search 3 has been Clicked.", Toast.LENGTH_SHORT).show();
                    editor.putString("position","0");
                    editor.apply();
                }
            }
        }));

        links.add(new Pair<>(stringtohyperlink2, new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String position = sp.getString("position","0");
                if (position.equals("1")) {
                    Toast.makeText(MainActivity.this, "full 1 has been Clicked.", Toast.LENGTH_SHORT).show();
                    editor.putString("position","0");
                    editor.apply();
                }
                if (position.equals("2")) {
                    Toast.makeText(MainActivity.this, "full 2 has been Clicked.", Toast.LENGTH_SHORT).show();
                    editor.putString("position","0");
                    editor.apply();
                }
                if (position.equals("3")) {
                    Toast.makeText(MainActivity.this, "full 3 has been Clicked.", Toast.LENGTH_SHORT).show();
                    editor.putString("position","0");
                    editor.apply();
                }
            }
        }));


        makeLinks(fulltext, links);


    }

    public void makeLinks(TextView textView, List<Pair<String, View.OnClickListener>> links) {
        SpannableString spannableString = new SpannableString(textView.getText().toString());

        int startIndexState = -1;
        SharedPreferences.Editor editor = sp.edit();

        for (Pair<String, View.OnClickListener> link : links) {
            ClickableSpan clickableSpan = new ClickableSpan() {
                @Override
                public void onClick(@NonNull View widget) {
                    editor.putString("position","1");
                    editor.apply();

                    widget.invalidate();
                    assert link.second != null;
                    link.second.onClick(widget);
                }
            };
            ClickableSpan clickableSpan2 = new ClickableSpan() {
                @Override
                public void onClick(@NonNull View widget) {
                    editor.putString("position","2");
                    editor.apply();

                    widget.invalidate();
                    assert link.second != null;
                    link.second.onClick(widget);
                }
            };

            ClickableSpan clickableSpan3 = new ClickableSpan() {
                @Override
                public void onClick(@NonNull View widget) {
                    editor.putString("position","3");
                    editor.apply();

                    widget.invalidate();
                    assert link.second != null;
                    link.second.onClick(widget);
                }
            };
            //... This only allows for 3 repeated words
            //... Add more of it, if there are more repeated words.

            assert link.first != null;
            int startIndexOfLink = textView.getText().toString().indexOf(link.first, startIndexState + 1);
            spannableString.setSpan(clickableSpan, startIndexOfLink, startIndexOfLink + link.first.length(), Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

            int startIndexOfLink2 = textView.getText().toString().indexOf(link.first, startIndexOfLink + 1);
            if (startIndexOfLink2 != -1) {
                spannableString.setSpan(clickableSpan2, startIndexOfLink2, startIndexOfLink2 + link.first.length(), Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
            }

            int startIndexOfLink3 = textView.getText().toString().indexOf(link.first, startIndexOfLink2 + 1);
            if (startIndexOfLink3 != -1) {
                spannableString.setSpan(clickableSpan3, startIndexOfLink3, startIndexOfLink3 + link.first.length(), Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
            }
            //... This only allows for 3 repeated words
            //... Add more of it, if there are more repeated words.

            textView.setMovementMethod(LinkMovementMethod.getInstance());
            textView.setText(spannableString, TextView.BufferType.SPANNABLE);
        }
    }
}

在xml

  <TextView
        android:id="@+id/fulltext"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

Demo

 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。

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()
    },
)
