如何设置文本视图中的某一部分可点击

对于那些正在寻找 Kotlin 解决方案的人，以下是对我有用的内容：

private fun setupTermsAndConditions() {
    val termsAndConditions = resources.getString(R.string.terms_and_conditions)
    val spannableString = SpannableString(termsAndConditions)
    val clickableSpan = object : ClickableSpan() {
        override fun onClick(widget: View) {
            if (checkForWifiAndMobileInternet()) {
                // binding.viewModel!!.openTermsAndConditions()
                showToast("Good, open the link!!!")

            } else {
                showToast("Cannot open this file because of internet connection!")
            }

        }

        override fun updateDrawState(textPaint : TextPaint) {
            super.updateDrawState(textPaint)
            textPaint.color = resources.getColor(R.color.colorGrey)
            textPaint.isFakeBoldText = true
        }
    }

    spannableString.setSpan(clickableSpan, 34, 86, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
    binding.tvTermsAndConditions.text = spannableString
    binding.tvTermsAndConditions.movementMethod = LinkMovementMethod.getInstance()
    binding.tvTermsAndConditions.setHighlightColor(Color.TRANSPARENT);

}

对于 Kotlin，请使用此扩展

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

binding.agreeText.makeLinks(Pair(getString(R.string.terms_conditionsClick),View.OnClickListener {
        startActivity(TermsAndConditionActivity.getIntent(this))
    }))

嘭！献给Java爱好者的内容 :D 我们可以根据自己的需求进行修改：

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

        pairsList.add(new Pair<>("38,50", v -> {
            Intent intent = new Intent(SignUpActivity.this, WebActivity.class);
            intent.putExtra("which", "tos");
            startActivity(intent);
        }));

        pairsList.add(new Pair<>("81,95", v -> {
            Intent intent = new Intent(SignUpActivity.this, WebActivity.class);
            intent.putExtra("which", "policy");
            startActivity(intent);
        }));

        makeLinks(pairsList); // Method calling


private void makeLinks(List<Pair<String, View.OnClickListener>> pairsList) {

        SpannableString ss = new SpannableString(By signing up, I’m agree to PAKRISM’s Terms of Use and confirms that I have read Privacy Policy);

        for (Pair<String, View.OnClickListener> pair : pairsList) {

            ClickableSpan clickableSpan = new ClickableSpan() {
                @Override
                public void onClick(View textView) {
                    //Toast.makeText(MyApplication.getAppContext(), "Clicked!", Toast.LENGTH_SHORT).show();
                    pair.second.onClick(textView);
                }

                @Override
                public void updateDrawState(TextPaint ds) {

                    ds.linkColor = ContextCompat.getColor(SignUpActivity.this, R.color.primary_main);
                    ds.setUnderlineText(true);

                    super.updateDrawState(ds);
                }
            };

            String[] indexes = pair.first.split(",");
            ss.setSpan(clickableSpan, Integer.parseInt(indexes[0]), Integer.parseInt(indexes[1]), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
        
        TextView tv = findViewById(R.id.txtView);
        tv.setText(ss);
        tv.setMovementMethod(LinkMovementMethod.getInstance());
    }

使用扩展方法以优雅的 Kotlin 方式创建:

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)
}

Using URLSpan class to get urls

val spans: Array<URLSpan> = result.getSpans(0, result.length, URLSpan::class.java)

方法

fun TextView.createClickable(string: String, action:(String)->Unit ) {
      text = HtmlCompat.fromHtml(string, HtmlCompat.FROM_HTML_MODE_LEGACY)
      val result = SpannableString(text)
      val spans = result.getSpans(0, result.length, URLSpan::class.java)
      for (span in spans) {
          val link:Pair<String, View.OnClickListener> = Pair(span.url, View.OnClickListener {
              action(span.url)
          })
          val start = result.getSpanStart(span)
          val end = result.getSpanEnd(span)
          val flags = result.getSpanFlags(span)
          result.removeSpan(span)
          val clickableSpan: ClickableSpan = object : ClickableSpan() {
              override fun onClick(textView: View) {
                  textView.invalidate()
                  link.second.onClick(textView)
              }
              override fun updateDrawState(textPaint: TextPaint) {
                  super.updateDrawState(textPaint)
                  textPaint.isUnderlineText = false
              }
          }
          result.setSpan(clickableSpan, start, end, flags)
          this.movementMethod = LinkMovementMethod.getInstance()
          this.setText(result, TextView.BufferType.SPANNABLE)
      }
  }

使用

示例文本： Android是一个软件堆栈，非常棒

将可点击的文本包装在锚点标签内

例如：Android是一个软件<a href='https://example.com/stack'>堆栈</a>，非常<a href='https://example.com/awesome'>棒</a>。

 val str = "Android is a Software <a href='https://example.com/stack'> Stack </a> and it' <a href='https://example.com/awesome'> Awesome </a>."

textView.createClickable(str) {
    when(it) {
        "https://example.com/stack"->{
  startActivity(Intent(this,StackActivity::class.java))
                  }
        "https://example.com/awesom"->{
            startActivity(Intent(this,AwesomeActivity::class.java))
        }
    }
}

这里有一个Kotlin解决方案，更适合本地化：

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)
}

并像这样使用它：

textView.setPartiallyLinkedText(
    LinkedText(R.string.not_linked_text),
    LinkedText(R.string.linked_text) {
        Toast.makeText(context, "You clicked", Toast.LENGTH_LONG).show()
    },
)

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()
}

加粗文字：

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

    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"/>

Java解决方案（2022年更新）

特点：

• 当有重复单词时，允许多个可点击。
• 可以为每个重复单词定制特定命令。

我在daler445的代码基础上进行了改进，以允许为重复单词添加多个可点击命令。

在Java类中：

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();

                }
            }
        }));


        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) {

                    link.second.onClick(widget);
                }
            };

            ClickableSpan clickableSpan3 = new ClickableSpan() {

            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);
        }
    }
}
