you must know that ,your scrollview property is set as MatchParent ,which means it will fill the content view, so i suggest to set Height a real value such as 100dp, and it will work
You need to dynamically change the height of the recyclerview, depending on how many items you have.
int recyclerheight = height_per_item * adapterData.size();
recyclerView.getLayoutParams().height = recyclerheight;
The scroll view blocks the recyclerview from changing its height set in the xml, that's why you need to do it programically.
