SpannableStringBuilder，ClickSpan 不工作，clickspan 到多个字符串 android

Question

我正在尝试使用 spannable 生成器实现对单个 TextView 的多次单击，我尝试了多种方法来实现对 spannable 字符串的单击但失败了，请指导我done/or 在这里做的事情。

            <androidx.appcompat.widget.AppCompatCheckedTextView
                android:id="@+id/cb_terms_of_service"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentStart="true"
                android:layout_marginStart="@dimen/sdp_16"
                android:layout_marginTop="@dimen/sdp_12"
                android:layout_marginBottom="@dimen/sdp_31"
                android:drawableLeft="@drawable/tos_check_box_selector"
                app:layout_constraintStart_toStartOf="parent" />

            <LinearLayout

所以问题出在这一行

{
                bold {
                    append("Terms and Conditions ")
                }

                object :ClickableSpan(){
                    override fun onClick(view: View) {
                        showTermsAndConditions()
                    }
                }
            }

在 span 内添加了点击，它开始正常工作，还添加了这一行 binding.termAndCondtionLabel.movementMethod = LinkMovementMethod.getInstance()

    inSpans(
          object :ClickableSpan(){
            override fun onClick(view: View) {
                showKeys()
            }


override fun updateDrawState(ds: TextPaint) { //to remove line //from spannable string
                          super.updateDrawState(ds)
                          ds.isUnderlineText = false
                      }
        },

        ForegroundColorSpan(ContextCompat.getColor(binding.termAndCondtionLabel.context,R.color.red_daily_limit))
    ){
        bold {
            append("Key Fact Statement ")
        }
    }
