我试图通过xamarin c＃在android中添加多个电话号码的联系人。这是一个按钮，我想在其中添加联系人。
我尝试了从传递数组到尝试单独添加第二个数字的所有内容，但后一个解决方案只是在实际保存之前覆盖第一个数字（如可疑）。
我在某处（可能在xamarin论坛上）读到，在Xamarin.ios中，我们可以一次性将所有电话号码添加为数组。
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 I want the contact to look like after it's added
更新： 这是我的完整功能的样子：
//Restore Contacts
private void CreateCon_Click(object sender, EventArgs e)
{
try

如何通过xamarin c＃？
在Android中添加多个电话号码的联系人
修改您的NewContact代码，如下所示：
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添加联系人时：
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();
}
}
我的Mi 5s中的Huawei Nexus 6P中的效果。
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();
}
}
