I tried the new lib and is not adding the new pictures, just a blank space.

Hi NJDude,

U have to populate first with a few images and leter add image but it doesnt add from assets just from sdcard.

 

[NJDude]

Ok, the problem is that you have this on the demo:

Coverflow.AddImage(File.DirRootExternal,"ANY IMAGE HERE")

It should be:

Coverflow.AddImage(File.DirRootExternal,"<IMAGE_FOLDER>/IMAGE_NAME")

Hi Theera,

I'm using NJDude's AlternateSample and I've changed the PopulateGallery line to be

Gallery.PopulateGallery(File.DirRootExternal, File.DirAssets)

because I've added 15 jpegs via the Files tab.

I'm getting NullPointerException. Any idea why?

The second parameter is a path to a file name not a directory, you are doing it wrong.

Hi NJDude,

Thanks for your reply.

Thanks. I put the folder name there because in the popup help box that appears while you're typing it says "Your FolderName Here" for the second parameter.
Anyway I've changed it now so the second parameter is a filename and it's still not working. I'm loading one jpeg that's 950kb. Perhaps it's too big. I'll have another look tomorrow.

Hi,
I have upgraded to 2.80 and not the demo programs do not run at all.
Dim Gallery As B4AGalleryView creates an error.
The library is loaded.
What can I do?

 

[lonleystar]

Hi grafsoft, now U've to use Dim Gallery As PhotoGallery instead of B4AGalleryView have a look below

Sub Globals
    Dim Gallery As PhotoGallery 
End Sub

Sub Activity_Create(FirstTime As Boolean)

    Activity.AddMenuItem("Populate From SdCard","b")
    Activity.AddMenuItem("Populate From Assets","c")
    Activity.AddMenuItem("Clear Cache","d")
    Gallery.Initialize("Gallery")
    Gallery.CreateCache = "Pippo.Pluto.Paperino"
    Activity.AddView(Gallery, 0, 0, 100%x, 100%y)
    Gallery.TextSize = 12
    Gallery.TextColor = Colors.Yellow
    Gallery.ShowText = True
    Gallery.ItemWidth = 300
    Gallery.ItemHeight = 400
    Gallery.Spacing = 10dip
End Sub

Sub b_Click
    Gallery.PopulateGallery(File.DirRootExternal, "Images2")
    Gallery.Selection = 33
    Activity.Title = "G.Salvi - Items = " & Gallery.Length & " -  Width = " & Gallery.ItemWidth&" | Height = "&Gallery.ItemHeight
End Sub

Sub c_Click

    Activity.Title = "G.Salvi - Items = " & Gallery.Length & " -  Width = " & Gallery.ItemWidth&" | Height = "&Gallery.ItemHeight
End Sub

Hi Guys, B4AGallery is update to v2.90 wath's new:

PopulateGalleryFromMediaStore

it'll populate the gallery with all images from ( sdcard and external card ) with out given any path.

minor fix.

the zip include the demo and the Library 2.90.

 

[lonleystar]

Hi guys, the new update 3.0 brings many improvements and stability of the library.

What's new:

- ScaleType
- SetOval
- SetBorderColor
- SetBorderWidth
- SetNoEffect


ScaleType - is used to fit the image inside the oval Example:
Gallery.ScaleType = Gallery.ScaleType.Fit_Center

SetCornerRadius - as no effects when SetOval = true



- Removed isFromAssets - have a look at the demo

- fix: When populating the Gallery from sdcard and add an image from assets and vice versa.

- fix: Now you can not only upload images from a folder in assets but also directly from the assets.

- fix: When an image is corrupt, will display an X icon, but you can choose another icon instead of (ic_error.png), and put it in your Files folder's project with the same name.

- you can choose another icon when populating the Gallery instead of (empty_photo.png) with the same name.

and many other fix

The zip include the new demo and the lib 3.0

Any comment or thanks will be appreciated. below is some attach.

I tried your version 3 but all I get is a red cross. The right number of files is displayed in the top left corner so my folder is read, but nothing is displayed.

 

[lonleystar]

Hi Informatix, It's always a pleasure to hear U.

Can U make an example code? I would like to understand better if it's not a problem for U.
