android - How to change Layout params in Activity from Fragment -

-

i have these layouts in activity:

  • linearlayout1
  • linearlayout2
  • frame1
  • frame2 (view.gone)

and have fragmenta in frame1. how can make 

frame1.setvisibility(view.gone); frame2.setvisibility(view.visible); fragment = fragmnt2(); fragmenttransaction.replace(frame2, fragment);

from fragment? how can access parent activity fragment?

you can use getactivity() parent activity make sure oncreate has been called first otherwise getactivity() null.
