android - passing context to fragment -
well doing small android project involving fragments.. log cat showing null pointer exception context value null..
this code
public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { view rootview = inflater.inflate(r.layout.syllabusselection, container, false); main(rootview); return rootview; } public void main(view rootview) { textview textyear,textsubject,textschema,textpowered ; final context context = getactivity(); typeface roboto = typeface.createfromasset(context.getassets(), "fonts/roboto/roboto-light.ttf"); typeface nexa = typeface.createfromasset(context.getassets(),"fonts/nexa/nexa_light.ttf");//nexa_light.ttf nexa_bold.ttf textsubject = (textview)rootview.findviewbyid(r.id.textsubject); textschema = (textview)rootview.findviewbyid(r.id.textscheme); textpowered = (textview)rootview.findviewbyid(r.id.textpowered); well
final context context = getactivity();
was null changed getactivity() still getting null pointer excewption.. errror??

move invocation of main onactivitycreated of fragment. means should move rootview.findviewbyid calls oncreateview , retain typeface calls in main.
