Merhaba,

Android de fragment kullanarak bir uygulama yazmaya çalıştım ancak aşağıdaki hatayı alıyorum.

E/AndroidRuntime: FATAL EXCEPTION: main

Kodları birbirine karıştırarak baya çorba yapmışım, Emre beyin ilgisi sayesinde birçok hatanın farkına vardım. Verdiği ekstra bilgilerden, ilgisi ve alakasından dolayı kendisine çok teşekkür ederim.

Selam ;

onCreateView methodlarının içersini aşağıdaki şekilde düzeltir misin

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment1, container, false);
    linearLayout = (LinearLayout) rootView.findViewById(R.id.linearlayout);
    return rootView;
}
