i can call method on each on item selected change. but, want refreshing fragment. in each switch case, want refresh fragment. please me solve this.

edit 1:

there 3 fragments, attached main activity:

mtabhost.setup(this, getsupportfragmentmanager(), r.id.realtabcontent);          mtabhost.addtab(mtabhost.newtabspec("tab1").setindicator("today's verse"),                 todayverse.class, null);         mtabhost.addtab(mtabhost.newtabspec("tab2").setindicator("today's chapter"),                 todaychapter.class, null);         mtabhost.addtab(mtabhost.newtabspec("tab3").setindicator("complete qur'an"),                 completequran.class, null); 

you can detach , attach fragment below

    fragment currentfragment = getfragmentmanager().findfragmentbytag("tab2");     fragmenttransaction fragtransaction = getfragmentmanager().begintransaction();     fragtransaction.detach(currentfragment);     fragtransaction.attach(currentfragment);     fragtransaction.commit(); 

this refresh view , locale change
