public class ListePro {``
    private int Id;
    private String Tarih;
    private String Saat;
    private String Miktar;
    private String Hareket;

    public ListePro(int id, String tarih, String saat, String miktar, String hareket) {
        Id = id;
        Tarih = tarih;
        Saat = saat;
        Miktar = miktar;
        Hareket = hareket;
    }

    public int getId() {
        return Id;
    }

    public void setId(int id) {
        Id = id;
    }

    public String getTarih() {
        return Tarih;
    }

    public void setTarih(String tarih) {
        Tarih = tarih;
    }

    public String getSaat() {
        return Saat;
    }

    public void setSaat(String saat) {
        Saat = saat;
    }

    public String getMiktar() {
        return Miktar;
    }

    public void setMiktar(String miktar) {
        Miktar = miktar;
    }

    public String getHareket() {
        return Hareket;
    }

    public void setHareket(String hareket) {
        Hareket = hareket;
    }
}

 public List<ListePro> getProliste() {

        ListePro listePro = null;
        List<ListePro> listpro = new ArrayList<>(  );
        SQLiteDatabase db = this.getWritableDatabase();
        String selectQuery = "SELECT  *  FROM  tablo ";
        Cursor c = db.rawQuery(selectQuery,null);
        while (!c.isAfterLast()){
            listePro = new ListePro( c.getInt( 0 ),c.getString( 1 ),c.getString( 2 ),c.getString( 3 ),c.getString( 4 ) );
            listpro.add( listePro );
            c.moveToNext();
        }
        return listpro;
    }



 public void VerileriAktar(ListView lv) {
        db = new DataBase(this);
        List<ListePro> mlistemPro = db.getProliste();
        ProAdaptor adapter = new ProAdaptor(MainActivity.this,mlistemPro);
        lv.setAdapter(adapter);
    }
