getactivity().getactionbar().setdisplayhomeasupenabled(true); maybe there difference in new support library? weird, did previous setup month ago.
another thing first installed android studio , sdk, , pointed eclipse sdk, maybe problem? code working on old machine not posting here, if need can.
edit:
@targetapi(11) public view oncreateview(layoutinflater inflater, viewgroup parent, bundle savedinstancestate) { /* int resource, viewgroup root, boolean attachtoroot */ view v = inflater.inflate(r.layout.fragment_crime, parent, false); // enabling button on menu bar shown if (build.version.sdk_int >= build.version_codes.honeycomb) { /* * action bar (guess button in particular) compatible holo.light * theme, maybe others idk. there way around complicated, need * use supportactionbar */ if (navutils.getparentactivityname(getactivity()) != null) { getactivity().getactionbar().setdisplayhomeasupenabled(true); } } mtitlefield = (edittext) v.findviewbyid(r.id.crime_title); mtitlefield.settext(mcrime.gettitle()); mtitlefield.addtextchangedlistener(new textwatcher() { public void ontextchanged(charsequence c, int start, int before, int count) { mcrime.settitle(c.tostring()); } @override public void beforetextchanged(charsequence s, int start, int count, int after) { } @override public void aftertextchanged(editable s) { } }); mdatebutton = (button) v.findviewbyid(r.id.crime_date); mdatebutton.setonclicklistener(new view.onclicklistener() { /* * standard procedure of sending info between fragments of same activity - use * newinstance */ @override public void onclick(view v) { fragmentmanager fm = getactivity().getsupportfragmentmanager(); datepickerfragment dialog = datepickerfragment.newinstance(mcrime.getdate()); /* * setting target receive request_date after child dead; first set * request_date string; used private void sendresult(int * resultcode) , dialoginterface.onclicklistener in positive button in * datepickerfragment, overriding onactivityresult necessary in here */ dialog.settargetfragment(crimefragment.this, request_date); dialog.show(fm, dialog_date); } }); mtimebutton = (button) v.findviewbyid(r.id.crime_time); mtimebutton.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { fragmentmanager fm = getactivity().getsupportfragmentmanager(); timepickerfragment dialog = timepickerfragment.newinstance(mcrime.getdate()); dialog.settargetfragment(crimefragment.this, request_time); dialog.show(fm, dialog_time); } }); mdeletebutton = (button) v.findviewbyid(r.id.crime_delete); mdeletebutton.settext(r.string.delete_crime); mdeletebutton.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { uuid crimeid = (uuid) getarguments().getserializable(extra_crime_id); crimelab crimelab = crimelab.get(getactivity()); crime crime = crimelab.get(getactivity()).getcrime(crimeid); crimelab.deletecrime(crime); crimelab.savecrimes(); getactivity().finish(); } }); mphotobutton = (imagebutton) v.findviewbyid(r.id.crime_imagebutton); mphotobutton.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { intent = new intent(getactivity(), crimecameraactivity.class); startactivity(i); } }); // disabling camera button devices without camera packagemanager pm = getactivity().getpackagemanager(); if (!pm.hassystemfeature(packagemanager.feature_camera) && !pm.hassystemfeature(packagemanager.feature_camera_front)) { mphotobutton.setenabled(false); } msolvedcheckbox = (checkbox) v.findviewbyid(r.id.crime_solved); msolvedcheckbox.setchecked(mcrime.issolved()); msolvedcheckbox.setoncheckedchangelistener(new oncheckedchangelistener() { public void oncheckedchanged( /* checkbutton needs compoundbutton */compoundbutton buttonview, boolean ischecked) { mcrime.setsolved(ischecked); } }); updatedate(); updatetime(); return v; }
it states out actionbar null. if you're using support library try
getactivity().getsupportactionbar().setdisplayhomeasupenabled(true); instead of
getactivity().getactionbar().setdisplayhomeasupenabled(true);
