Button click throws nullpointerexception in fragment

Question

Im getting an error when I press the button in my fragment view. The button is rendered but when I click it I get the following error:

09-23 18:29:01.242 9332-9332/? E/AndroidRuntime﹕ FATAL EXCEPTION: main java.lang.NullPointerException at foit.startingpoint.nl.androiddrawer.LocatiesFragment.onCreateView(LocatiesFragment.java:28)

     @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    Button button = (Button) getView().findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent myIntent = new Intent(LocatiesFragment.this.getActivity(), SecondActivity.class);
            startActivity(myIntent);            }
    });
    
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_locaties, container, false);
}

Answer 1

your initializing is incorrect, you must do as following code:

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

           View view = inflater.inflate(R.layout.fragment_locaties, container, false);
           Button button = (Button) view.findViewById(R.id.button);
           button.setOnClickListener(new View.OnClickListener() {
             @Override
             public void onClick(View v) {
                  Intent myIntent = new Intent(getActivity(),SecondActivity.class);
                        startActivity(myIntent); 
             }
    });

    return view;
}

as onCreateView not finished getView is null in your code so you must create one view and use that.
