Android Question Simple Media Manager - get bitmap ?

[derez]

I'm using smm and want to save the bitmap which is set to the specified panel. The image is said to be on view(0) on the panel, which is said to be b4ximageview. I would like to know how to get the bitmap for saving it.

Dim vx As B4XImageView = Picpnl.GetView(0)

This gives "types do not match"

Note that SMM will create different types of views, based on the media type.

B4XImageView is not a real view. It is a class that wraps a view. More information here: https://www.b4x.com/android/forum/t...om-clv-or-any-other-container.117992/#content

Solution:

Dim vx As B4XImageView = Picpnl.GetView(0).Tag

I get

java.lang.IllegalArgumentException: field b4a.example.b4xmainpage._vx has type b4a.example.b4ximageview, got java.lang.String

The Tag is interpreted as a regular tag, a string.

Perhaps it is not the only view in the Picpnl. What do you get with this?

    For i = 0 To Picpnl.NumberOfViews - 1
        Dim vw As B4XView = Root.GetView(i)
        If Not(vw.Tag Is String) Then
            Log(i & TAB & GetType(vw.tag))
        End If
    Next

Also this is a custom view and should be added with designer and .loadlayout.

Correct way to get the bitmap is demonstrated here https://www.b4x.com/android/forum/t...m-a-link-using-smm-to-disk.159787/post-980984

The solution to my question is actually much simpler , although not the exact answer to the question, to use result.mediafile :

Private Sub ShowMedia (Result As MediaChooserResult)
   
    If Result.Success Then
        smm.SetMediaFromFile(design.Picpnl, Result.MediaDir, Result.MediaFile, Result.Mime, Null)
       File.Copy(Result.MediaDir, Result.MediaFile, rp.GetSafeDirDefaultExternal(""), "temp.jpg")
        B4XPages.ShowPage("design")
    Else
        design.Picpnl.RemoveAllViews
    End If

End Sub
