android - Add fragment at certain angle -

i have multiple fragments dynamically changing within activity. instances fragments need added in landscape orientation while in portrait. how specify angle @ fragment must added activity ?

my current code:

getfragmentmanager.begintransaction()                 .setcustomanimations(r.animator.fadein, r.animator.fadeout)                 .add(r.id.fragment_container, playerpane, tag).commit(); 

oncreateview method:

@override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {      view rootview = inflater.inflate(r.layout.fragment_player_pane, container, false);     framelayout.layoutparams params = (framelayout.layoutparams) rootview.getlayoutparams();      // set width height     params.height = (getarguments().getint(height));     params.width = (getarguments().getint(width));       params.setmargins((getarguments().getint(left_margin)),             (getarguments().getint(top_margin)),             (getarguments().getint(right_margin)),             (getarguments().getint(bottom_margin)));      rootview.setlayoutparams(params);      return rootview; } 

you can check configuration of device see whether in portrait or landscape , use in if statement launch different fragment.

if (getresources().getconfiguration().orientation == configuration.orientation_portrait) {     // launch portrait fragment } else {     // launch landscape fragment } 

as addition, if writing application, try not change fragment being added depending on orientation, rather have fragment present views differently depending on orientation through use of targeted xml , checks within fragment itself.
