Android Question ImageView ScaleType

socialnetis · Sep 21, 2013

Hi, I'm using this piece of code to change the ScaleType of an ImageVIew:

B4X:

Sub SetScaleType(i As ImageView,ScaleType As String)
    Dim r As Reflector
    r.Target = i
    r.RunMethod2("setScaleType",ScaleType,"android.widget.ImageView$ScaleType")
    Log(r.RunMethod("getScaleType"))
End Sub

The Log shows that the ScaleType is the one I set, however I can't see any effect in the ImageView (I tried with CENTER_INSIDE and CENTER_CROP).

What am I missing?

I'm not sure about this method. However you can use the "resize bitmap" code I posted here to manually scale the bitmap: http://www.b4x.com/android/forum/threads/live-wallpaper-background.24907/#post-144401

Ok, after using ICOSImageview which exposes this method, and seeing that they work, I realized that the common ImageView' bitmap property, is actually for the background.

Shouldn't this be fixed? For example, if someone wants to use a padding in the imageview (lets say for a picture frame), and red background color (for the frame's color) and then set the bitmap, they will actually override the full ImageView background, and not the container of the ImageView.

I know that there is always a workarround (for example using the imageview in front of a panel, and use the panel as the frame), but maybe the bitmap property should be the correct one, to explode all the potencial using the reflection library.
