I am displaying max 5 elements in RecyclerView and I would like it to set it's height depending on number of elements that have been added inside it. For example when I inserted 5 elements I would like it to display 3 elements - rest coudl be scrolled down. If I download only 1 I woould like to display only that 1 without scrolling. When RecyclerView will not get any elemetns I would like to set it' height to 0 so it would not be visibile. Any ideas how to achieve this? I must set height manulayy to show anything. When no items are inserted RecyclerView shows blank, empty space which I want to avoid. Any ideas? I also tried to remove RecyclerView and try to insert views to separate LinearLayout but that didn't work. Here is my post about it but noone helped me :/ (Adding custom View to LinearLayout dynamicly does not work)
