How to make a loading indicator when scrolling to the top?
Given that when the user releases, from automatically leaving to the bottom?
And it is necessary to somehow take into account that how much it is shown, so that the reload action would begin only after it is fully shown.
I had an idea to put the table in the scrollview, but I don't know how to prevent the table from dragging the first element.
I simply did not find in the table how to catch the pulling of the zero cell and determine, all the more, how much it is pulled.
