方法不会从其超类重写方法

Question

Can anyone tell me, why this error is displayed (or even have a better solution)?
I'm new to Java (and Android) development, so I realy don't know my fault My Code:

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;


public class select_type extends Fragment {


    public select_type() {
        // Required empty public constructor
    }

    @Override //<--- Cause the ERROR
    public View onCreateView(View view, LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        return inflater.inflate(R.layout.fragment_select_type, container, false);

        Button btn = (Button) view.findViewById(R.id.btn);

        btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                noVIP TextFragment = new noVIP();
                FragmentTransaction transaction = getFragmentManager().beginTransaction();
                transaction.replace(R.id.fragment_container, TextFragment);
                transaction.addToBackStack(null);
                transaction.commit();
            }
        });

        return view;
    }

}

Answer 1

Replace:

public View onCreateView(View view, LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

with:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

as onCreateView() is not passed a View parameter .

Also, get rid of super.onViewCreated(view, savedInstanceState); . It is neither necessary nor appropriate to be calling that where you are.

Please note that everything after your return statement in that method will not be executed, since you are returning first. Assign the inflater.inflate(...) result to a local variable, use it, then return that variable at the end of your method.

Answer 2

You can override two methods also:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.fragment_select_type, container, false);
}




@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

   Button btn = (Button) view.findViewById(R.id.btn);

    btn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            noVIP TextFragment = new noVIP();
            FragmentTransaction transaction = getFragmentManager().beginTransaction();
            transaction.replace(R.id.fragment_container, TextFragment);
            transaction.addToBackStack(null);
            transaction.commit();
        }
    }); 

  }
