前言

android中通过SpannableStringBuilder实现一个TextView中不同颜色显示和部分文字的点击事件

提示：以下是本篇文章正文内容，下面案例可供参考

一、ClickableSpan添加部分文字的点击事件

val mSpannableStringBuilder: SpannableStringBuilder = SpannableStringBuilder()
        mSpannableStringBuilder.append("登录/注册即表示同意<<用户协议>>")
        val mClickableSpan: ClickableSpan = object : ClickableSpan() {
            override fun onClick(widget: View) {
                val action = RichTextFragmentArgs("title", "type").toBundle()
                Navigation.findNavController(widget).navigate(R.id.richText, action)
            }

        }
        mSpannableStringBuilder.setSpan(
            mClickableSpan, 10, mSpannableStringBuilder.length,
            Spannable.SPAN_INCLUSIVE_INCLUSIVE
        )
        mFragmentLoginBinding!!.tvUserAgreement.highlightColor =
            Color.TRANSPARENT //设置点击后的颜色为透明，否则会一直出现高亮
        mFragmentLoginBinding!!.tvUserAgreement.text = mSpannableStringBuilder
        mFragmentLoginBinding!!.tvUserAgreement.movementMethod = LinkMovementMethod.getInstance()

设置字体可点击后，可点击部分字体的颜色会变。

二、ForegroundColorSpan设置部分字体的颜色

        val mForegroundColorSpan: ForegroundColorSpan =
            ForegroundColorSpan(requireActivity().resources.getColor(R.color.green_FF00612E))
        mSpannableStringBuilder.setSpan(
            mForegroundColorSpan, 10, mSpannableStringBuilder.length,
            Spannable.SPAN_INCLUSIVE_INCLUSIVE
        )
        mFragmentLoginBinding!!.tvUserAgreement.text = mSpannableStringBuilder

三.先设置可点击，再设置字体颜色

val mSpannableStringBuilder: SpannableStringBuilder = SpannableStringBuilder()
        mSpannableStringBuilder.append(mFragmentLoginBinding!!.tvUserAgreement.text.toString())
        val mClickableSpan: ClickableSpan = object : ClickableSpan() {
            override fun onClick(widget: View) {
                val action = RichTextFragmentArgs("title", "type").toBundle()
                Navigation.findNavController(widget).navigate(R.id.richText, action)
            }

        }
        mSpannableStringBuilder.setSpan(
            mClickableSpan, 10, mSpannableStringBuilder.length,
            Spannable.SPAN_INCLUSIVE_INCLUSIVE
        )
        mFragmentLoginBinding!!.tvUserAgreement.highlightColor =
            Color.TRANSPARENT //设置点击后的颜色为透明，否则会一直出现高亮
        mFragmentLoginBinding!!.tvUserAgreement.text = mSpannableStringBuilder
        mFragmentLoginBinding!!.tvUserAgreement.movementMethod = LinkMovementMethod.getInstance()


        val mForegroundColorSpan: ForegroundColorSpan =
            ForegroundColorSpan(requireActivity().resources.getColor(R.color.green_FF00612E))
        mSpannableStringBuilder.setSpan(
            mForegroundColorSpan, 10, mSpannableStringBuilder.length,
            Spannable.SPAN_INCLUSIVE_INCLUSIVE
        )
        mFragmentLoginBinding!!.tvUserAgreement.text = mSpannableStringBuilder
