How to force the grid to redraw when handling configuration changes manually?

[minlite]

I'm loading a lot of data in my StaggeredGridView and reloading it after a configuration change (i.e orientation change) would take a long time. So I have marked to handle the orientation change myself.

When the orientation is changed from portrait to landscape while displaying a 2 column grid, the columns overlap each other. I believe it is because the view is not remeasuring and redrawing the layout.

How can I force measure and draw the StaggeredGridView in my onConfigurationChanged method?

I have tried using requestLayout(), invalidate(), and forceLayout() but none of them seems to solve my issue.

Thanks

notifyDataSetChanged() on your adapter

@minlite @blundell Have you solved this issue? calling notifyDataSetChanged() does nothing...
