I am trying to make my scrollview change length in the program. When I use:
it doesn't have an influence on the length of the scrollable area. I am loading view panel1 that contains bunch of other views:
With this:
I can get it to scroll but not to change the length later in the code.
I tried this in the code:
Button1 is the last view that should be visible on the bottom of the scrollable area.
Later I realized that I can't do it like that
because for some reason it returns wrong values.
When I made a test app and made the most simple thing it Toasted 450:
I think it can't be more simple than this. Either I am terribly wrong somewhere or there is a bug.
Thanks so much if you can help me
B4X:
ScrollView1.Panel.Height
B4X:
ScrollView1.Panel.AddView(Panel1,0,0,GetDeviceLayoutValues.Width,1000dip)With this:
B4X:
ScrollView1.Initialize(1000dip)I tried this in the code:
B4X:
Panel1.Height=Button1.Top+15dip+110dip
ScrollView1.Panel.Height=Panel1.Height
ScrollView1.Height=ScrollView1.Panel.HeightLater I realized that I can't do it like that
B4X:
ScrollView1.Height=ScrollView1.Panel.HeightWhen I made a test app and made the most simple thing it Toasted 450:
