Hi,

New to B4A and have a problem with variable imageview.
i want to line-up the images with something like this.
the dim ImV1(40) as imageview is done above


Posleft =
10

PosTop =
10

For t= 1 To 40

ImV1(t).Width = 70dip
ImV1(t).Height = 70dip
ImV1(t).Bitmap= LoadBitmap(File.DirAssets, "MyPicture.jpg")

If t<11Then 'until 11 is one line

ImV1(t).Left= PosLeft

ImV1(t).Top = PosTop

PosLeft=PosLeft + 80 '10dip between the imageviews

Else

PosLeft =
10 'left is resetted

PosTop =
80 ' top as for line.

EndIf
ImV1(t).Visible=True

Next


any suggestions why this is not working?

Can you use the [ code ] tags to make the code more readable please?

What are you expecting to happen?

What is happening?

B4X: 
Dim PosLeft As Int
Dim PosTop As Int
Posleft = 10dip
PosTop = 10dip
For t= 1 To 40
    ImV1(t).Bitmap = LoadBitmap(File.DirAssets, "brain.jpg")
If t<11 Then    'until 11 is one line
    ImV1(t).Width  = 70dip
    ImV1(t).Height = 70dip
    ImV1(t).Left= PosLeft
    ImV1(t).Top = PosTop
    PosTop=PosTop + 80    '10dip between the imageviews
Else
      PosLeft = 10
      PosTop = 80
End If  
    ImV1(t).Visible=True

Where is the code that creates the image views and adds them to the activity or panel?
Click to expand...
I added folowing line in de For t=1to40:


activity.AddView(ImV1(t),10dip,10dip,70dip,70dip)

but keep getting error now on the initialize
what to write in there? i tried ImV1(t).Initialize ("ImageView1")


Thanks.

Two suggestions:
- Read this thread How to ask a question
- Send your project as a zip file (IDE menu Files / Export As Zip)
So we can see what you have done and how.

The quastion can be closed. i figured is out with the remark of Erel.
I did not initialise and no add.
the thing i have to figure out now is the click event to all images shown.

Thanks

You set the eventname with the initialization... for ex iv.initialize("image")
B4X: 
Sub image_Click
    If Sender Is Button
        Dim but As Button
        but = Sender
        Log(but.Text)
    End If
End Sub
