Wie beheben Sie Setcontentview Fehler und innere Klassenfehler in dieser Fragmentklasse?

Question

Das ist also eine Fragmentklasse. Ich versuche, einige Elemente zu listview mit Baseadaptor hinzufügen. Ich bin ein Anfänger, also bin ich dieser Frage gefolgt. How to customize listview using baseadapter Aber jetzt bekomme ich Setcontentview Fehler (Fehler konnte nicht behoben werden) bei Zeile Nr. 72 und innerer Klassenfehler bei 147. Also bitte hilf mir, es zu reparieren. Paketlayout;

In Ihrem onCreateView Sie das aufgeblasene Layout auf der ersten Zeile zurückkehren. ändern Sie es in

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     myfragment = inflater.inflate(R.layout.fragment_ussd, container, false); 
     //getting error at thus part "cannot resolve setcontentview" 
     l1=(ListView)myfragment.findViewById(R.id.listView); 
     l1.setAdapter(new dataListAdapter(t1,d1,i1)); 
     return myfragment; 
     }
