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

Question

我正在尝试使用spannable builder实现单个TextView上的多次点击，我尝试了多种方法来实现点击spannable字符串，但失败了，请指导我我做了什么/或在这里做错了。

Answer 1

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click，它开始正常工作，并且还添加了这行binding. termandconditionlabel。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 ")
}
}
