I have a map view where I add two layers-- a base layer and an aerial layer. The base layer is of type ArcGISTiledMapServiceLayer where as the aerial layer is of type ArcGISDynamicMapServiceLayer. I would like to set the alpha on the aerial layer so that it is essentially transparent to begin with. I also have a slider control where it will affect the aerial layer's alpha value.
I can't seem to find anywhere on how to set the alpha value. I'm using Android level 7 (2.1). The only thing I can think of is using Android's own View, which has a "setAlpha", but this is only for level 11 (3.0) and up, which is not even supported officially by Esri.
Any ideas? Thanks.
