firemonkey开发通讯录app

1、添加AddressBook1+MultiView1+speedbuttonX3+labelX#+editboxX3+buttonX2+listbox组件。

2、对listbox右键additem选择tsearchbox类型。

3、设置MultiView1的属性。

4、设置edit1、edit2、edit3的属性。

KillFocusByReturn:=true; 
ReturnKeyType:=Go;

5、编写罗列通讯录以及添加通讯录代码。

procedure TForm1.FillContactList;
var
  I: Integer;
  Contacts: TAddressBookContacts;
begin
  Contacts := TAddressBookContacts.Create;
  try
    AddressBook1.AllContacts(AddressBook1.DefaultSource, Contacts);
    ListBox1.BeginUpdate;
    try
      ListBox1.Clear;
      for I := 0 to Contacts.Count - 1 do
        AddListBoxItem(Contacts.Items[I]);
    finally
      ListBox1.EndUpdate;
    end;
  finally
    Contacts.Free;
  end;

end;

procedure TForm1.AddListBoxItem(Contact: TAddressBookContact);
var
  ListBoxItem: TListBoxItem;
begin
  try
    ListBoxItem := TListBoxItem.Create(nil);
    ListBoxItem.Text := Contact.DisplayName;
    ListBoxItem.Tag := Contact.ID;
    ListBox1.AddObject(ListBoxItem);
  finally
    ListBoxItem.Free;
  end;

end;

6、添加删除某条记录以及刷新代码。

procedure TForm1.SpeedButton4Click(Sender: TObject);
var
  Contactlndex, ContactID: Integer;
  Contact: TAddressBookContact;
begin
  Contactlndex := ListBox1.Itemindex;
  if (Contactlndex > -1) then
  begin
    ContactID := ListBox1.Listitems[Contactlndex].Tag;
    Contact := AddressBook1.ContactByID(ContactID);
    if Contact <> nil then
    try
      AddressBook1.RemoveContact(Contact);
      ListBox1.BeginUpdate;
      ListBox1.Items.Delete(Contactlndex);
    finally
      ListBox1.EndUpdate;
      Contact.Free;
    end;
  end;

end;

procedure TForm1.SpeedButton5Click(Sender: TObject);
begin
  FillContactList;
end;

添加通讯录记录代码。

procedure TForm1.Button1Click(Sender: TObject);
var
  Contact: TAddressBookContact;
  eMails: TContactEmails;
  Addresses: TContactAddresses;
begin
  Contact := AddressBook1.CreateContact(AddressBook1.Defaultsource);
  try
    Contact.FirstName := edtFirstName.Text;
    Contact.LastName := edtLastName.Text;
// Add the work mail
    eMails := TContactEmails.Create;
    try
      eMails.AddEmail(TContactEmail.TLabelKind.Work, edtWorkEmail.Text);
      Contact.eMails := eMails;
    finally
      eMails.Free;
    end;
    AddressBook1.SaveContact(Contact);
    try
      ListBox1.BeginUpdate;
      AddListBoxItem(Contact);
    finally
      ListBox1.EndUpdate;
    end;
  finally
    Contact.Free;
  end;
  MultiView1.HideMaster;

end;

取消按钮代码。

procedure TForm1.Button2Click(Sender: TObject);
begin
  edtFirstName.Text := '';
  edtLastName.Text := '';
  edtWorkEmail.Text := '';
  MultiView1.HideMaster;

end;

要求获得权限代码。

uses
    FMX.DialogService;

procedure TForm1.FormShow(Sender: TObject);
begin
// Display this information box while loading the contacts
  if AddressBook1.Supported then
  begin
    TDialogService.ShowMessage(' Loading contacts ...');
    AddressBook1.RequestPermission;
  end
  else
    showmessage('This platform does not support the Address Book service1');

end;

如果有权限执行读入代码。

procedure TForm1.AddressBook1PermissionRequest(ASender: TObject; const AMessage: string; const AAccessGranted: Boolean);
begin

  if AAccessGranted then
  begin
    FillContactlist;
  end
  else
    ShowMessage('You cannot access Address Book. Reason: ' + AMessage);

end;

设置app的使用权限。
