Android Question Label Background Image Aspect Ration

[Jmu5667]

hi

I have a navigation bar in my app. It has 3 labels which size themselves based on the screen width. Each label has an image assigned to their background(done in the designer) the images are smaller then the label widths.

If the user clicks one of the labels I want to change the background image, but when I do the result is a distorted backgound. How can I maintain the aspect ratio as it it when the app load ?

Sub lblSettings_Click

   lblSettings.Gravity = Gravity.CENTER
   lblSettings.SetBackgroundImage(LoadBitmap(File.DirAssets, "settings_on.png"))



End Sub

the settings in the designer are;

Thanks.

John.

Consider using a Button instead. This way you will be able to set the different images with the designer.

Yes that is a possible solution, but I really would like to know why the aspect ratio is not maintained in the label, or if there is a code workaround.

The label gravity doesn't affect the BitmapDrawable gravity.
You can create a BitmapDrawable object with the bitmap and correct gravity and then set it as the label background.

ContactsUtils.FindAllContacts should be very fast. Once you start to fetch information for each contact it becomes slower.
