如何通过 xamarin c# 在 android 中添加具有多个 phone 号码的联系人？

Question

我正在尝试通过 xamarin c# 在 android 中添加具有多个 phone 号码的联系人。这是我要添加联系人的按钮。

我尝试了从传递数组到尝试单独添加第二个数字的所有方法，但后一种解决方案只是在实际保存之前覆盖第一个数字（怀疑）。

我在某处（可能是在 xamarin 论坛上）读到，在 Xamarin.ios 中我们可以一次性将所有 phone 数字添加为一个数组。

        private void test_Click(object sender, EventArgs e)
    {
        List<ContentProviderOperation> ops = new List<ContentProviderOperation>();

        ContentProviderOperation.Builder builder =
            ContentProviderOperation.NewInsert(RawContacts.ContentUri);
        builder.WithValue(RawContacts.InterfaceConsts.AccountType, null);
        builder.WithValue(RawContacts.InterfaceConsts.AccountName, null);
        ops.Add(builder.Build());

        //Name
        builder = ContentProviderOperation.NewInsert(Data.ContentUri);
        builder.WithValueBackReference(Data.InterfaceConsts.RawContactId, 0);
        builder.WithValue(Data.InterfaceConsts.Mimetype,
                          StructuredName.ContentItemType);
        builder.WithValue(StructuredName.FamilyName, "Added fname");
        builder.WithValue(StructuredName.GivenName, "firstName");
        ops.Add(builder.Build());

        List<string> a = new List<string>();
        a.Add("89892302398");
        a.Add("93823239232");
        //Number
        builder = ContentProviderOperation.NewInsert(Data.ContentUri);
        builder.WithValueBackReference(Data.InterfaceConsts.RawContactId, 0);
        builder.WithValue(Data.InterfaceConsts.Mimetype,
                          cont.ContentItemType);
        builder.WithValue(cont.Number,"83293982" ); //tried to pass array here a.ToArray()

        builder.WithValue(cont.InterfaceConsts.Type,
                          cont.InterfaceConsts.TypeCustom);
        builder.WithValue(cont.InterfaceConsts.Label, "Work");

        builder.WithValue(cont.InterfaceConsts.Number, "808004038");
        builder.WithValue(cont.InterfaceConsts.Type,
                          cont.InterfaceConsts.TypeCustom);
        builder.WithValue(cont.InterfaceConsts.Label, "Home");

        ops.Add(builder.Build());

        //Add the new contact
        ContentProviderResult[] res;
        try
        {
            res = ContentResolver.ApplyBatch(Authority, ops);

            Toast.MakeText(this, "contact saved !", ToastLength.Short).Show();
        }
        catch
        {
            Toast.MakeText(this, "contact not saved_message !", ToastLength.Long).Show();
        }

    }

在我的项目中，我试图从我之前创建的 csv 文件中恢复联系人，但唯一的问题是我无法保存具有多个号码的联系人。我应该看起来像：

How to add a contact with multiple phone numbers in android via xamarin c#?

像这样修改您的 NewContact 代码：

public void NewContact(ref List<ContentProviderOperation> ops, string displayName, string Number1, string Number2, string Number3, string Number4)
    {
        ContentProviderOperation.Builder builder =
            ContentProviderOperation.NewInsert(ContactsContract.RawContacts.ContentUri);
        builder.WithValue(ContactsContract.RawContacts.InterfaceConsts.AccountType, null);
        builder.WithValue(ContactsContract.RawContacts.InterfaceConsts.AccountName, null);
        ops.Add(builder.Build());

        //Name  
        builder = ContentProviderOperation.NewInsert(ContactsContract.Data.ContentUri);
        builder.WithValueBackReference(ContactsContract.Data.InterfaceConsts.RawContactId, 0);
        builder.WithValue(ContactsContract.Data.InterfaceConsts.Mimetype,
                          ContactsContract.CommonDataKinds.StructuredName.ContentItemType);
        builder.WithValue(ContactsContract.CommonDataKinds.StructuredName.DisplayName, displayName);
        //builder.WithValue(ContactsContract.CommonDataKinds.StructuredName.GivenName, firstName);  
        ops.Add(builder.Build());

        //Number1  
        builder = ContentProviderOperation.NewInsert(ContactsContract.Data.ContentUri);
        builder.WithValueBackReference(ContactsContract.Data.InterfaceConsts.RawContactId, 0);
        builder.WithValue(ContactsContract.Data.InterfaceConsts.Mimetype,
                          ContactsContract.CommonDataKinds.Phone.ContentItemType);
        builder.WithValue(ContactsContract.CommonDataKinds.Phone.Number, Number1);
        builder.WithValue(ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Type,
                          ContactsContract.CommonDataKinds.Phone.InterfaceConsts.TypeCustom);
        builder.WithValue(ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Data2, (int)PhoneDataKind.Mobile);

        ops.Add(builder.Build());
        //Number2  
        if (!string.IsNullOrEmpty(Number2))
        {
            builder = ContentProviderOperation.NewInsert(ContactsContract.Data.ContentUri);
            builder.WithValueBackReference(ContactsContract.Data.InterfaceConsts.RawContactId, 0);
            builder.WithValue(ContactsContract.Data.InterfaceConsts.Mimetype,
                              ContactsContract.CommonDataKinds.Phone.ContentItemType);
            builder.WithValue(ContactsContract.CommonDataKinds.Phone.Number, Number2);
            builder.WithValue(ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Type,
                              ContactsContract.CommonDataKinds.Phone.InterfaceConsts.TypeCustom);
            builder.WithValue(ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Data2, (int)PhoneDataKind.Mobile);
            ops.Add(builder.Build());
        }

        if (!string.IsNullOrEmpty(Number3))
        {
            builder = ContentProviderOperation.NewInsert(ContactsContract.Data.ContentUri);
            builder.WithValueBackReference(ContactsContract.Data.InterfaceConsts.RawContactId, 0);
            builder.WithValue(ContactsContract.Data.InterfaceConsts.Mimetype,
                              ContactsContract.CommonDataKinds.Phone.ContentItemType);
            builder.WithValue(ContactsContract.CommonDataKinds.Phone.Number, Number3);
            builder.WithValue(ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Type,
                              ContactsContract.CommonDataKinds.Phone.InterfaceConsts.TypeCustom);
            builder.WithValue(ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Data2, (int)PhoneDataKind.Mobile);
            ops.Add(builder.Build());
        }

        if (!string.IsNullOrEmpty(Number4))
        {
            builder = ContentProviderOperation.NewInsert(ContactsContract.Data.ContentUri);
            builder.WithValueBackReference(ContactsContract.Data.InterfaceConsts.RawContactId, 0);
            builder.WithValue(ContactsContract.Data.InterfaceConsts.Mimetype,
                              ContactsContract.CommonDataKinds.Phone.ContentItemType);
            builder.WithValue(ContactsContract.CommonDataKinds.Phone.Number, Number4);
            builder.WithValue(ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Type,
                              ContactsContract.CommonDataKinds.Phone.InterfaceConsts.TypeCustom);
            builder.WithValue(ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Data2, (int)PhoneDataKind.Mobile);
            ops.Add(builder.Build());
        }
    }

然后当您使用此方法时添加联系人：

new_Contact_Button.Click += (sender, args) =>
{

    List<ContentProviderOperation> ops = new List<ContentProviderOperation>();
    NewContact(ref ops, "lizi", "1234" , "2234", "3234", "4234");

    //Add the new contact
    ContentProviderResult[] res;
    try
    {
        res = ContentResolver.ApplyBatch(Authority, ops);
        ops.Clear();//Add this line   
        Toast.MakeText(this, "contact saved !", ToastLength.Short).Show();
    }
    catch
    {
        Toast.MakeText(this, "contact not saved_message !", ToastLength.Long).Show();
    }
}

在我的 Mi 5s, in my Huawei Nexus 6P 中生效。

更新：

保存联系人时添加ops.Clear()。

public void SaveContacts(string filename)  
{  
    var documentsPath = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDownloads);  
    var filePath = Path.Combine(documentsPath.AbsolutePath, filename);  
    var fileContent = File.ReadAllLines(filePath);  

    List<ContentProviderOperation> ops = new List<ContentProviderOperation>();  

    foreach (var strLine in fileContent)  
    {  
        if (string.IsNullOrEmpty(strLine))  
            continue;  
        var array = strLine.Split(new string[] { "\t", ":" }, StringSplitOptions.RemoveEmptyEntries);  

        NewContact(...);  

        //Add the new contact  
        ContentProviderResult[] res;  
        res = ContentResolver.ApplyBatch(ContactsContract.Authority, ops);  
        ops.Clear();   
    }  
}
