Android Question image update in customlistview

PumaCyan · Feb 3, 2023

Hi all...

how to make the image on the list change to the newest image instantly

because at this point when there is a change in the image, the image in the list is not replaced immediately

even if I exit the page, when I reload the lists, the image is still the same, the old image

Dim p As Panel = CustomListView1.GetPanel(0) 'Get the panel of the item you need to modify. Here is 0, so the first item in the CLV
Dim iv As ImageView = p.GetView(0) 'Get a reference to the ImageView to modify. 0 if imageview is the first view in the panel. It depends on your Views Tree
iv.Bitmap = LoadBitmap(dir, image_filename) 'Change the image

Sorry I forgot to add... The image is sourced from an online server

You can retrieve the image from every source you need.
Then just assign it to the imageview with the same procedure.
