Android Question Change background color of CustomListView

The background color of CLV is the divider color. The items are separated with a small gap and you actually see the background. You can change this color with the designer.

There is no single foreground color. You can change the background of each item.

I don't mean the gaps but rather the background colors for each panel and the text that's in each of the panels, is there a way to change all of them at once ?

Use a For loop to get all panels and then change their colors.
