Android Rotation (Load Layout) data loss (id and data / Custom Objects etc.) -

i turning view, same horizontally. contains many variables of type textview, progressbar, imageview, etc .. can not load variables when rotated.

i tried do:

android: configchanges = "keyboardhidden | orientation | screensize | screenlayout" 

i find methods can save customized classes, progressbar, views "my nothing."

when there anyway load landscape (another layout (with same id's)) of not losing data?

to change layout use:

http://developer.android.com/reference/android/app/activity.html#onconfigurationchanged(android.content.res.configuration)

update code 10/04/2015 (0:45 am)

my rotation :

@override public void onconfigurationchanged(configuration newconfig) {     super.onconfigurationchanged(newconfig);      if (newconfig.orientation == configuration.orientation_landscape) {         super.onconfigurationchanged(newconfig);         setcontentview(r.layout.activity_1);      } else if (newconfig.orientation == configuration.orientation_portrait){         super.onconfigurationchanged(newconfig);         setcontentview(r.layout.activity_2);     }    } 

oncreate

 @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);          if (getresources().getconfiguration().orientation == configuration.orientation_landscape) {                 setcontentview(r.layout.activity_1);          } else if (getresources().getconfiguration().orientation == configuration.orientation_portrait){                            setcontentview(r.layout.activity_2);  } 

references : saving android activity state using save instance state can't sabe objects exits of activity. "i think"

the easiest way not specify orientation configchanges. correspondingly, not need override onconfigurationchanged -- can load layout in oncreate , state should part preserved. if needed state data can stored in onsaveinstancestate (and restored in oncreate).
