Get DPI from MapView

SimonKlein — Mon, 19 Mar 2012 07:00:04 GMT

Hi,

is there a way to get the DPI from the MapView?
I need it for a parameter of a IdentifyParameters object.
In the the IdentifiyTask Sample it is hardcoded with 96.

Thanks!

DisplayMetrics from developer.android.com

Thanks, but this gives me not really the DPI of the MapView. It only provides the general DPI of the device ( DENSITY_DEFAULT, DENSITY_HIGH, etc.) which are just 160,240,etc. and not the normal DPI of the MapView. In the Windows Phone and the IOS API versions there is something like MapView.getDPI().
So I am a little confused if I should just also use the hardcoded 96dpi or do it the DisplayMetrics way.
Recommendations?

I'm not sure, and I can't test it, as the result i do not understand what is it? - getResolution()

Gets the resolution of the Layer.

and

But may be ... setDPI(int)

Sets the dot-per-inch of the map (used to determine the resolution of the map).

Are the same things... :confused:

I'm not sure. I have no SDK installed on current working machine - I can't try it.
