java - Android Tab View unable to getIntent() -

java - Android Tab View unable to getIntent() -

i trying tab in android project. here tab main page:

public class eventdetailmain extends fragmentactivity { context context = this; viewpager tab; eventdtltabpageradapter tabadapter; actionbar actionbar; @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.event_detail_main); tabadapter = new eventdtltabpageradapter(getsupportfragmentmanager()); tab = (viewpager) findviewbyid(r.id.pager); tab.setonpagechangelistener(new viewpager.simpleonpagechangelistener() { @override public void onpageselected(int position) { actionbar = getactionbar(); actionbar.setselectednavigationitem(position); } }); tab.setadapter(tabadapter); actionbar = getactionbar(); // enable tabs on action bar actionbar.setnavigationmode(actionbar.navigation_mode_tabs); actionbar.tablistener tablistener = new actionbar.tablistener() { public void ontabreselected(android.app.actionbar.tab tab, android.app.fragmenttransaction ft) { } public void ontabselected(android.app.actionbar.tab tab, android.app.fragmenttransaction ft) { // on tab selected show respected fragment view tab.setcurrentitem(tab.getposition()); } public void ontabunselected(android.app.actionbar.tab tab, android.app.fragmenttransaction ft) { } }; // add together new tab actionbar.addtab(actionbar.newtab().settext("event detail") .settablistener(tablistener)); actionbar.addtab(actionbar.newtab().settext("chat room") .settablistener(tablistener)); actionbar.addtab(actionbar.newtab().settext("drop review") .settablistener(tablistener)); }

and content of first tab:

public class eventdetail extends fragment { context context; view eventdetail; @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { eventdetail = inflater.inflate(r.layout.event_detail, container, false); context = this; intent = getintent(); event eventmodel = (event) i.getserializableextra("eventobj"); }

}

however, getting error message "type mismatch: cannot convert eventdetail context" @ context = , "the method getintent() undefined type eventdetail" @ getintent().

any ideas? because did not extends activity?

thanks in advance.

yes. in fragment have getactivity(). there can utilize getintent().

edit so: first error - context = this; should context = getactivity(); sec error - getintent() should getactivity().getintent();

edit2: have 3rd error :d need homecoming view :

return eventdetail;

and also, not using eventmodel anywhere.
