setContentView in fragment

I'm trying to convert a Activity to fragment. The error mark on setContentView.

here is my code

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_googlev2);
    Init();
    addMarkersToMap();
    yStart = 21.102918;
    yEnd = 20.960798;
    xStart = 105.772762;
    xEnd = 105.900650;
    xNow = xStart;
    yNow = yStart;
    adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_dropdown_item_1line);
    textView = (AutoCompleteTextView) getView().findViewById(R.id.autoCompleteTextView1);
    textView.setThreshold(3);
    adapter.setNotifyOnChange(true);
    textView.setAdapter(adapter);
    textView.addTextChangedListener(new TextWatcher() {
        public void onTextChanged(CharSequence s, int start, int before, int count){
            autoCount = count;
            autoS = s;
            if(autoCount % 3 == 1) {
                stCommand = "AutoCompleteTextView";
                lp = new ExecuteTask();
                lp.execute();
            }
        }
        public void beforeTextChanged(CharSequence s, int start, int count, int after){ // TODO Auto-generated method stub
        }
        public void afterTextChanged(Editable s){
        }
    });
}

how to convert that setContentView ?

bclymer has the correct answer to what you are asking, I just would like to add that you can also take care of findViewById inside that method like such:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {             
    View rootView = inflater.inflate(R.layout.activity_googlev2, container, false);
    textView = (AutoCompleteTextView) rootView.findViewById(R.id.autoCompleteTextView1);
    return rootView;
}

Also, onCreateView is called after onCreate so if you try to use findViewById in your onCreate it will return null since there is no layout view attached yet.

This shouldn't go in onCreate, you must override onCreateView

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {             
    View rootView = inflater.inflate(R.layout.activity_googlev2, container, false);
    return rootView;
}
