怎么用：

val confirm = ConfirmDialog(this@MypageFragmentView, "ログアウトしてもよろしいでしょうか？", "いいえ", "はい")
confirm.setClicklistener(object : ConfirmDialog.ClickListenerInterface {
    override fun doConfirm() {

        logoutApi(this@MypageFragmentView)

        confirm.dismiss()
    }

    //いいえ
    override fun doCancel() {
        confirm.dismiss()
    }
})
confirm.show()

val confirmDialog = ConfirmDialog(this@MyThemeWebView, msg, "いいえ", "はい", false)

confirmDialog.setOnKeyListener { dialog, keyCode, event ->
    if (keyCode == KeyEvent.KEYCODE_BACK && event!!.repeatCount == 0) {
        handler.cancel()
    }
    false
}

confirmDialog.setClicklistener(object : ConfirmDialog.ClickListenerInterface {
    override fun doConfirm() {
        handler.proceed()
        confirmDialog.dismiss()
    }

    //いいえ
    override fun doCancel() {
        handler.cancel()
        confirmDialog.dismiss()
    }
})

confirmDialog.show()
