Activity crash (android fragments)

Question

Im started today wth fragments on android(till now i only used activities) and I get a crash after running the app(actually it doesnt even launch).

import android.content.Intent;

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.TextView;





/**

 * A simple {@link Fragment} subclass.

 */

public class MainFragment extends Fragment {





    public MainFragment() {

        // Required empty public constructor

    }





    @Override

    public View onCreateView(LayoutInflater inflater, ViewGroup container,

                             Bundle savedInstanceState) {

        // Inflate the layout for this fragment

        init();//----> PROBLEM HERE

        return inflater.inflate(R.layout.fragment_main, container, false);



    }





    public TextView login;

    /** Called when the user clicks link for Login/Register on right corner of the app*/

    public void init() {

        login=(TextView) getView().findViewById(R.id.textView11_linkRegister);

        login.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                //intent means what i want to do'

                Intent openLoginForm = new Intent(getActivity(),Login.class);

                startActivity(openLoginForm);

            }

        });

    }





}

I made the

Init()

function andeverything worked good till i tried to call it on

onCreateView()

I know the problem must be the way I call that function.
I would appreciate any help.

THanks.

You can't access a view that does not yet exist, rewrite your code like this:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View v = inflater.inflate(R.layout.fragment_main,container,false);
    init(v);//----> PROBLEM HERE
    return v;

}


public TextView login;
/** Called when the user clicks link for Login/Register on right corner of the app*/
public void init(View v) {
    login=(TextView) v.findViewById(R.id.textView11_linkRegister);
    login.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //intent means what i want to do'
            Intent openLoginForm = new Intent(getActivity(),Login.class);
            startActivity(openLoginForm);
        }
    });
}
