NinePatchDrawable can not be cast... error

[cmweb]

Hello,

I got an error report from a user of one of my apps.

The app uses Packagemanager to gather all installed apps and their icons. The error appears within that code...

Error:

      packages = pm.GetInstalledPackages

         DoEvents

      Next
      ProgressDialogHide
      
      Activity.AddView(packlist,0,0,100%x,100%y)
      packlist.Visible = False
      packlist.BringToFront
      packlist.Color = Colors.black
   
   End If 'Ende First Time Packagelist

end sub

I can not reproduce that error message on my devices.

Any ideas, why that error appears?

Best regards,

Carsten

PackageManager.GetApplicationInfo returns a Drawable object. It might not be a BitmapDrawable.

You can test whether it is a BitmapDrawable with:

If pm.GetApplicationIcon(packname) Is BitmapDrawable Then ...

If you want to convert a non BitmapDrawable to a BitmapDrawable then you need to:
- Create a mutable bitmap
- Draw the drawable with Canvas.DrawDrawable

Thanks Erel, I understand...

Best regards,

Hello Erel,

If you want to convert a non BitmapDrawable to a BitmapDrawable then you need to:
- Create a mutable bitmap
- Draw the drawable with Canvas.DrawDrawable

Could you please explain that to me?

I didn't work with mutable bitmaps and canvas so far...

Best regards,

Carsten

Post the code that you are trying to build and I will further help you.

Post the code that you are trying to build and I will further help you.

This is the code:

If pm.GetApplicationIcon(packname) Is BitmapDrawable Then
            icons = pm.GetApplicationIcon(packname)
            packlist.AddTwoLinesAndBitmap2(applabel,"",icons.bitmap,packname)
         Else
            ' Convert to Bitmap and add it to the packlist Listview
         End If

Else should convert to bitmap and add it to the packlist.

The canvas.drawDrawable requires a RECT parameter and I don't know what that should be when the bitmap shoud just be added to a listview...

Thanks for your help.

Best regards,

Carsten

DestRect defines the target area in the bitmap. You should create a bitmap with the required width and height (same size as the ListView bitmap size) and then create a Rect with: Rect.Initialize(0, 0, bmp.Width, bmp.Height).
