SpannableStringBuilder，ClickSpan 不工作，clickspan 到多個字符串 android

Question

我正在嘗試使用 spannable builder 在單個 TextView 上實現多次單擊，我嘗試了多種方法來實現單擊 spannable 字符串但失敗了，請指導我在這里做了什么/或做着什么。

<RelativeLayout

Answer 1

所以問題出在這條線上

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

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

在 span 內添加 click 並開始正常工作，還添加了這一行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 ")
        }
    }
