var period2 = "用户服务协议"
var period3 = "和"
var period4 = "隐私政策条款"
var period = period1 + period2 + period3 + period4
var buider = SpannableStringBuilder()
buider.append(period)
buider.setSpan(object : ClickableSpan() {
    override fun onClick(p0: View) {
        Toast.makeText(this@MainActivity, "用户服务协议", Toast.LENGTH_LONG).show()
    }
    override fun updateDrawState(ds: TextPaint) {
        super.updateDrawState(ds)
        ds.color = getColor(R.color.black)
    }

}, period1.length, period1.length + period2.length, 0)
buider.setSpan(object : ClickableSpan() {
    override fun onClick(p0: View) {
        Toast.makeText(this@MainActivity, "隐私政策条款", Toast.LENGTH_LONG).show()
    }
    override fun updateDrawState(ds: TextPaint) {
        super.updateDrawState(ds)
        ds.color = getColor(R.color.black)
    }
}, period1.length + period2.length + period3.length, period.length, 0)

tvTest?.movementMethod = LinkMovementMethod.getInstance()
tvTest?.text = buider
//点击的背景
tvTest?.highlightColor = Color.parseColor("#00000000")
