Magnify tool

SwatiGadey — Mon, 12 Dec 2011 17:39:28 GMT

ArcGIS app for Android has a Magnify tool upon long pressing on the map. I am trying to replicate this functionality using ViewSwitcher. But, when I create two MapView objects in XML, my map doesn't load.

Any ideas on how to approach? Is ViewAnimator, a better way of approaching this problem?

I would also like to know this, because my customers want this feature too.

You can do this by getting the image of the map using getDrawingCache(). This worked for me in case of Beta release.

However, with the SDK v1.0.1 this portion of code broke. The new method introduced (for this purpose) in this release: mapview.getDrawingMapCache returns null.

I am still waiting on a response regarding this.

Please take a look at the GeometryEditing sample, it has the magnify tool.

You may have found a bug with getMapDrawingCache, we are looking into it.

Thanks
