Remove one row from gridlayout

I'm using a GridLayout with 5 coloums and multiple (not a fix value) rows. It is possible to add more rows with values to the grid by a add button (the values are hardcoded in hashmap for now). In each row there is a delete button in the first cell. Now I want to implement, that if you hit the delete button, the complete row should be deleted but also other rows should stay. Any proposals how to do this?

It's difficult to explain without having your implementation, but I'll try. So suppose we have our Activity/Fragment with a RecyclerView. We have our Adapter who holds a List/Map/Anything with your elements in it. What we need is the delete button and it's click listener i guess. When you click the button you call a method in your adapter from the Activity/Fragment, which iterates your List/Map/Anything removing the items. The method then calls notifyDataSetChanged() on the Adapter again, and the grid should update correctly.

You could remove the specific dataset from your HashMap (or use another map in the adapter for the dymanic content) and then call:

grid.setRowCount(grid.getRowCount() - 1);
grid.notifyDataSetChanged();

That should remove the specific row.
