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

android.text.style.ClickableSpan可以解决你的问题。

SpannableString ss = new SpannableString("Android is a Software stack");
ClickableSpan clickableSpan = new ClickableSpan() {
    @Override
    public void onClick(View textView) {
        startActivity(new Intent(MyActivity.this, NextActivity.class));
    }
    @Override
    public void updateDrawState(TextPaint ds) {
        super.updateDrawState(ds);
        ds.setUnderlineText(false);
    }
};
ss.setSpan(clickableSpan, 22, 27, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

TextView textView = (TextView) findViewById(R.id.hello);
textView.setText(ss);
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setHighlightColor(Color.TRANSPARENT);

在XML:

<TextView 
  ...
  android:textColorLink="@drawable/your_selector"
/>

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

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。

大胆的,

mySpannable.setSpan(new StyleSpan(Typeface.BOLD),termStart,termStop,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

这是一个kotlin扩展(不工作，如果文本重复)

textView.makeTextClickable(
    contentText = "Hello world",
    clickableText = "world",
    isBoldText = true,
    onClick = {
        openPageInBrowser(BuildConfig.PRIVACY_POLICY_URL)
    }
)



   internal fun TextView.makeTextClickable(
    contentText: String,
    clickableText: String,
    onClick: () -> Unit,
    isUnderlineText: Boolean = false,
    isBoldText: Boolean = false
) {
    val spannableString = SpannableString(contentText)

    val clickableSpan = object : ClickableSpan() {
        override fun onClick(widget: View) {
            onClick()
        }

        override fun updateDrawState(ds: TextPaint) {
            super.updateDrawState(ds)
            ds.isUnderlineText = isUnderlineText
            ds.isFakeBoldText = isBoldText
        }
    }

    val clickableTextStartIndex = text.indexOf(clickableText)
    val clickableTextEndIndex = clickableTextStartIndex + clickableText.length

    spannableString.setSpan(
        clickableSpan,
        clickableTextStartIndex,
        clickableTextEndIndex,
        Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
    )

    this.text = spannableString
    this.movementMethod = LinkMovementMethod.getInstance()
}
