Hello Everyone If you also facing same problem then follow the instruction. i try a alternative way.
Impotent Information: We not able to render data at recycler without make list so we play with this list.
and if you change count value then also recycler refresh it shelf.
1st Step when you want to remove any item for sure you have to remove item from the list . i do using the procedure
Use REMOVE list item from list block
list is which list effect by
index is which index you want to remove.
Example you have a delete button when user click this button operate this block
recycler refresh automatically and item also delete form list : Remember you also use block for delete data from online database .
Thank You
