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)
}

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。

你可以像本文中描述的那样使用ClickableSpan

示例代码:

TextView myTextView = new TextView(this);
String myString = "Some text [clickable]";
int i1 = myString.indexOf("[");
int i2 = myString.indexOf("]");
myTextView.setMovementMethod(LinkMovementMethod.getInstance());
myTextView.setText(myString, BufferType.SPANNABLE);
Spannable mySpannable = (Spannable)myTextView.getText();
ClickableSpan myClickableSpan = new ClickableSpan() {
   @Override
   public void onClick(View widget) { /* do something */ }
};
mySpannable.setSpan(myClickableSpan, i1, i2 + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

您可以使用示例代码。您希望了解关于ClickableSpan的详细信息。请检查这份文件

  SpannableString myString = new SpannableString("This is example");
            
            ClickableSpan clickableSpan = new ClickableSpan() {
                    @Override
                    public void onClick(View textView) {
                        ToastUtil.show(getContext(),"Clicked Smile ");
                    }
                };
        
        //For Click
         myString.setSpan(clickableSpan,startIndex,lastIndex,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        
        //For UnderLine
         myString.setSpan(new UnderlineSpan(),startIndex,lastIndex,0);
        
        //For Bold
        myString.setSpan(new StyleSpan(Typeface.BOLD),startIndex,lastIndex,0);
        
        //Finally you can set to textView. 
        
        TextView textView = (TextView) findViewById(R.id.txtSpan);
        textView.setText(myString);
        textView.setMovementMethod(LinkMovementMethod.getInstance());

这是java爱好者的Boom Check:D 我们可以根据自己的需要进行修改:

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());
    }
