Android Sliding Menu Fragment launching fragment over -

the idea want transparent fragmentactivity placed on view. i've accomplished list click on is:

case 3:     intent intent = new intent(getactivity(), loginusingloginfragmentactivity.class);     startactivity(intent); break; } 

now once click facebook fragmentactivity login appears , have option login. when launches i'd sliding menu close , fragmentactivity appear or sliding menu close while fragmentactivity loads appears seamless. i'm using facebook sdk, sliding menu, , action bar sherlock in case matters.
