I have this code...
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        final RelationShipAdapter adapter = null;
        lvRelationShipAllUser.setOnItemClickListener(new AdapterView.OnItemClickListener(){
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int i, long l) {
                int test = i;
                connectOrDisconnectUser(test);
            }
        });
        lvRelationShipAllUser = (ListView) getView().findViewById(R.id.lvRelationShip);
        lvRelationShipAllUser.setAdapter(adapter);
        //context = BlankFragment.this;
        return inflater.inflate(R.layout.relationship, container, false);
    }
The error says:
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ListView.setOnItemClickListener(android.widget.AdapterView$OnItemClickListener)' on a null object reference
On this line:
lvRelationShipAllUser.setOnItemClickListener(new AdapterView.OnItemClickListener(){
Whats the issue....?
When it's in this own class (No Fragments) there is no issue.
