    public Button ok;
    public DataBaseHelper dataBaseHelper;
    public BaseAdapter baseAdapter;
    ArrayList<Employee> arrayList;

    @Override

        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 0);
        setContentView(R.layout.activity_main);
        initializedAll();
    }

    private void initializedAll() {

        editText = (EditText) findViewById(R.id.editText);
        listView = (ListView) findViewById(R.id.listView);
        ok = (Button) findViewById(R.id.okbutton);
        dataBaseHelper = new DataBaseHelper(this);
        arrayList = new ArrayList<Employee>();
        baseAdapter = new BaseAdapter() {

            LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            @Override
            public View getView(int position, View view, ViewGroup viewGroup) {
                if (view == null) {
                    view = inflater.inflate(R.layout.list_item, null);
                }

                TextView message = (TextView) view
                        .findViewById(R.id.messagetextView);
                TextView datetime = (TextView) view
                        .findViewById(R.id.datetextView);
                message.setText(arrayList.get(position).getName());
                Date date = arrayList.get(position).getDate();
                datetime.setText(DateFormat.format("dd/MM/yyyy hh:mm:ss a",
                        date));
                return view;
            }

            @Override
            public long getItemId(int position) {
                // TODO Auto-generated method stub
                return 0;
            }

            @Override
            public Object getItem(int position) {
                // TODO Auto-generated method stub
                return arrayList.get(position);
            }

            @Override
            public int getCount() {
                // TODO Auto-generated method stub
                return arrayList.size();
            }
        };

        listView.setAdapter(baseAdapter);

        ok.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                save(v);
            }
        });

    }

    public void save(View v) {

        String namedb = editText.getText().toString();
        Date date = new Date();
        Employee employee = new Employee(namedb, date);
        arrayList.add(employee);
        baseAdapter.notifyDataSetChanged();
        Toast.makeText(getApplicationContext(), employee.toString(),
                Toast.LENGTH_SHORT).show();
        long inserted = dataBaseHelper.insertEmployee(employee);

        if (inserted >= 0) {
            Toast.makeText(getApplicationContext(), "Data Inserted",
                    Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(getApplicationContext(), "Data not Inserted",
                    Toast.LENGTH_SHORT).show();
        }

        ArrayList<Employee> employees = dataBaseHelper.getAllEmlopyee();
        if (employees != null && employees.size() > 0) {

        } else {
            Toast.makeText(getApplicationContext(), "No data found",
                    Toast.LENGTH_SHORT).show();
        }
    }

}

What should i write in

ArrayList<Employee> employees = dataBaseHelper.getAllEmlopyee();
if (employees != null && employees.size() > 0) {
    here
} 

To show my data in ListView.
