How to dynamically control item width

[zhangle1]

I want to get the screen width -10dp as the width of item,
I tried doing it in onCreateViewHolder:
viewHolder= new viewHolder(_inflate);
ViewGroup.LayoutParams _layoutParams = viewHolder.mCardView.getLayoutParams();
layoutParams.width=_layoutParams.width-10;
viewHolder.mCardView.setLayoutParams(_layoutParams);
But it doesn't work.

I could suggest you to use match_parent as the item size and then apply the min/max scale. But you'll have to calculate the desired scale based on the measured item size.

thanks,I still have some questions about how I should control the position of item so that the second item can display an optional value
