There are oversights or mistakes on CustomListView for B4J.
1. i select divider color and divider height = 2 work fine but not in the first row see image 1.
2. if scroll bar not visible the row not end at border but 20dip before see image 2.
3. if i select a backgroud color when i expand the row the background takes the default color see image 3.
1. Why have you added a ScrollPane to the items layout?
2. Why are you loading each item with a height of 250dip and then changing the height?
3. The only issue I see is related to the scrollbar width. It happens because you set the text size to 12. It causes the scrollbar to become thinner. Set it to 15 instead.
