这是什么鬼？一个大括号不能为null？？
研究发现，是koltin的if表达式不能返回null
buttonText =
if (from == PayConstans.FROM_VIP_FULL_AD || from == PayConstans.FROM_STREAM_AD || privilegeId == PRIVILEGE_NO_AD) {
//广告拉起
fullScreenPayGuide.buttontextBean.`_$1`
} else if (from == PayConstans.FROM_VIP_FILM || from == PayConstans.FROM_VIP_TRAILER || from == PayConstans.FROM_VIDEO_DETAIL_FULL_PLAYER_TIP || from == PayConstans.FROM_VIP_MORE) {
fullScreenPayGuide.buttontextBean.`_$2`
} else if (from == PayConstans.FROM_VIP_RENEW
|| from == PayConstans.FROM_VIDEO_DETAIL_FULL_PLAYER_BUTTON
) {
fullScreenPayGuide.buttontextBean.`_$3`
} else if (from == PayConstans.FROM_HDR || from == PayConstans.FROM_DOWNLOAD || from == PayConstans.FROM_BULE || from == PayConstans.FROM_VIP_DANMU) {
fullScreenPayGuide.buttontextBean.`_$4`
} else {
fullScreenPayGuide.buttontextBean.`_$5`
}
fullScreenPayGuide.buttontextBean._$2 的结果是null，所以才导致了这个崩溃
