kotlin扩展函数避免快速点击

//定义有效点击时长
private var clickEffectiveTime = 1000L
//记录上次点击的时间    
private var lastClickTime: Long = 0

infix fun View.clickDelay(clickAction: () -> Unit) {
        this.setOnClickListener {
            if (this.hashCode() != hash) {
                hash = this.hashCode()
                lastClickTime = System.currentTimeMillis()
                clickAction()
            } else {
                val currentTime = System.currentTimeMillis()
                if (currentTime - lastClickTime > clickEffectiveTime) {
                    lastClickTime = System.currentTimeMillis()
                    clickAction()
                }
            }
        }
    }

使用

button clickDelay {
	//处理点击按钮的逻辑
}
