（四）使用Kotlin简单封装公用弹窗Dialog，Constr
之前总是遇到弹窗Dialog，为了方便以后使用，自己方便简单封装了一个Utils方便以后根据需求方便拓展应用。截图如下：

3.外部调用方式如下简单粗暴
CommonDialog.Builder(context)
.setTitle("用户提示") .setContent(userModel.userRiskEvaluationVO.showNeedEvaluationContent)
.setIcon(R.drawable.ic_risk)
.setConfirmText("确认")
.setCancelText("取消")
.setOnConfirmListener(object : CommonDialog.OnConfirmListener {
override fun onClick(dialog: Dialog) {
...
...
dialog.dismiss()
}
})
.setOnCancelListener(object : CommonDialog.OnCancelListener {
override fun onClick(dialog: Dialog) {
dialog.dismiss()
}
})
.create()
.show()
以上便是简单的dialog封装，以方便大家以后直接使用。
