android - How to handle orientation change in fragment in viewpager programmatically? -


i have 3 fragments,only 1 of them must change orientation(but not activity), activiy has flag congifchanges="orientation|screensize", , viewpager. want change layouts programmatically on every orientation change.

i have 2 different layouts, if scroll pages on viewpager, layout change expected.

what have:

enter image description here

what want:

enter image description here

as in such situations, seems decision should difficult implement. in fact, 3 lines:

@override public void onconfigurationchanged(configuration newconfig) {     super.onconfigurationchanged(newconfig);     viewgroup viewgroup = (viewgroup) getview();     viewgroup.removeallviewsinlayout();     view view = oncreateview(getactivity().getlayoutinflater(), viewgroup, null); viewgroup.addview(view); }

here found it

redrawing fragment not best idea if keeps data (plays video, map, etc.) because have no dynamically changing data there, , had show same thing, in different orientation, used approach if need change orientation , did not lose data must read this.
