I need some good advice please. I have a scrollview with a TableLayout. The table consists of 5 columns so every TableRow consists of 5 Textviews. It's working very well, but I would like to add more TableRows, and since I'm using:
private ActivityMainBinding binding;
there is a limit how many views it can handle. There must be a better way constructing a scrollable table with 5 columns that doesn't consume that many views?
I learned java programming by myself, so I know there is a lot of stuff I don't know. Maybe someone can point me in the right direction?
activity_main.xml:
<ScrollView

Accepted Answer
Use a RecyclerView. It will handle the scrolling, and it will only take 5*N views, where N is the number of rows visible on screen, no matter how many rows there actually are. It does that by recycling the views- remapping what rows are displayed in the same physical set of views.
