when i am doing 3d transition the animation gets stop for sometime

when i am doing 3d transition the view is stopping for some time and then rotating the two view contain first view a listview and map and second view a list view both views are interacting with database

(code block fixed)

/**

You get this "stop" while doing non 3d transactions? If not then you should enable DrawingCache to your views. This has effect mostly in TextViews since they redraw them selves at every step of the animation. Set View.setDrawingCacheEnabled(true); to your views.
