@koji-1009 Can you send pr for that?🙏

takahirom commented 5 years ago

In TimetableCurrentTimeLineDecoration.calcLineHeight, you can judge RecyclerView.NO_POSITION.

takahirom commented 5 years ago

It can be fixed that it will be blank at the beginning of the transition. However, I will resolve it when I return. It is not serious, so it is not a problem to fix from now.

OK, I'll take care of this.

Thanks. I'm thinking now this point.

takahirom commented 5 years ago

But I want to fix the crash so please pr.🙏

koji-1009 commented 5 years ago

Oh, sorry. I'm on the train now. I will send PR after 20 min. Is that is too late?

すいません、いま電車で移動中のためPR作成までに20分程かかりそうです。 間に合わないよであれば、他のかたにPRをお願いしたく 。。
