Android Tutorial B4XTable - Photos Album

In this example the table is used to show the camera roll photos.

Main steps:
1. Get permission to access the external storage.
2. Collect the image files from several folders.
3. Add the columns and add ImageViews to all cells.
4. Load the images when the table is updated.
5. Show a dialog with a large image when an image is clicked.

Edit (Erel): I've removed the large image. You should never post code or error messages as images.

 

[GMan]

You need the B4XTable lib and the Formatter lib, too

I have error with missing .jar

Cannot find: D:\Basic4android\libraries\b4xformatter.jar

But b4xformatter is a .b4xlib. Did I missed something?

 

[Erel]

Make sure that there is no file named B4XFormatter.xml in the libraries folders. You should only have a b4xlib file.

In the Table-Example is not the Photoalbum example, but another Table-Example

    'create the columns
    B4XTable1.AddColumn("US County", B4XTable1.COLUMN_TYPE_NUMBERS)
    B4XTable1.AddColumn("Name", B4XTable1.COLUMN_TYPE_TEXT)
    Dim StateColumn As B4XTableColumn = B4XTable1.AddColumn("State", B4XTable1.COLUMN_TYPE_TEXT)
    StateColumn.Width = 80dip
    NumberColumn = B4XTable1.AddColumn("Interesting Number", B4XTable1.COLUMN_TYPE_NUMBERS)
    CreateCustomFormat(NumberColumn)
    
    'load the data
    Dim su As StringUtils
    Dim headers As List
    headers.Initialize 'the list is only used to skip the headers row
    Dim data As List = su.LoadCSV2(File.DirAssets, "us_counties.csv", ",", headers)
    B4XTable1.SetData(data)
