ListView refresh after removing some items

Good day everyone. I want the ListView refresh after removing some items from database but I'm seeing a red lines underneath remove (cannot be resolved). I am having below code.

 public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listdisplay1);
        dbHelper = new MyDatabaseHelper(this);
        sqlcon = new InfoAPI(this);
        final String name1 = getIntent().getExtras().getString("name");
        BuildList(name1);

    }

    public void BuildList(String name) {
        final String name1 = name;
        sqlcon.open();
        Cursor cursor=sqlcon.readEntry(name1);

       String[] columns=new String[]{
               MyDatabaseHelper.Weather,MyDatabaseHelper.Date,MyDatabaseHelper.Status,MyDatabaseHelper.TimeIn_Info,MyDatabaseHelper.TimeOut_Info
       };

        int[] to=new int[]{
                R.id.weather,R.id.date,R.id.status,R.id.in,R.id.out
        };

        // create the adapter using the cursor pointing to the desired data
        //as well as the layout information
        dataAdapter = new SimpleCursorAdapter(
                this, R.layout.listdispaly,
                cursor,
                columns,
                to,
                0);

        ListView listView = (ListView) findViewById(R.id.listView1);
        // Assign adapter to ListView
        listView.setAdapter(dataAdapter);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> listView, View view,
                                    int position, long id) {
                // Get the cursor, positioned to the corresponding row in the result set
                Cursor cursor = (Cursor) listView.getItemAtPosition(position);

                // Get the state's capital from this row in the database.
                String ID =
                        cursor.getString(cursor.getColumnIndexOrThrow("_id"));
                String date1 = cursor.getString(cursor.getColumnIndexOrThrow("Date"));
                Intent intent = new Intent(ListDisplay.this, UpdatePage.class);
                intent.putExtra("name1", name1);
                intent.putExtra("date1", date1);
                intent.putExtra("ID", ID);
                startActivity(intent);
            }
        });

        listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            public boolean onItemLongClick(final AdapterView<?> p, View v, final int po, long id) {
             //   final long id1=id;
                AlertDialog.Builder builder = new AlertDialog.Builder(ListDisplay.this);
                builder.setTitle("Delete");
                builder.setMessage("Are you sure you want to delete?");
                builder.setIcon(android.R.drawable.ic_dialog_alert);
                builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int ii) {

                        database = dbHelper.getWritableDatabase();
                        Cursor cursor = (Cursor) p.getItemAtPosition(po);

                        // Get the state's capital from this row in the database.
                        long ID =
                                cursor.getLong(cursor.getColumnIndexOrThrow("_id"));
                      sqlcon.delete(ID);
                       p.remove(p.getItemAtPosition(po));
                        dataAdapter.notifyDataSetChanged();



                    }
                });
                builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener()

                        {
                            public void onClick(DialogInterface dialog, int ii) {
                                dialog.dismiss();
                            }
                        }

                );
                builder.show();
                return true;
            }
        });
    }

            }

Can someone help me to figure out the problem? I'm new to android and not sure is this the correct way to implement?Thanks
