You can always delegate contact creation to the Contacts app using the
ContactsContract.Intents.UI.Insert intent with extras. This will show the
edit UI.
If you want to explicitly create the contact by yourself, that's now a bit
tricky because Android 2.0 support multiple accounts.
First of all, you will need to figure out which account you want to create
the contact in. Get a list of all available accounts from AccountManager:
AccountManager am = AccountManager.get(getContext());
Account[] accounts = am.getAccounts();
Also, get a list of all sync adapters and find the ones that support
contacts:
SyncAdapterType[] syncs
= ContentResolver.getContentService().getSyncAdapterTypes();
for (SyncAdapterType sync : syncs) {
if (ContactsContract.AUTHORITY.equals(sync.authority) &&
sync.supportsUploading()) {
contactAccountTypes.add(sync.accountType);
}
}
Now you have a list of all accounts and a list of account types that support
contacts. So here's your account list:
for (Account acct: accounts) {
if (contactAccountTypes.contains(acct.type)) {
contactAccounts.add(account);
}
}
If the contactAccounts list contains nothing - use accountType = null and
accountName = null
If it contains exactly one account, use it.
If it contains multiple accounts, build a dialog and ask the user which
account to use.
>From here on it gets easier.
Let's start with a more traditional method. Insert a raw contact first:
ContentValues values = new ContentValues();
values.put(RawContacts.ACCOUNT_TYPE, accountType);
values.put(RawContacts.ACCOUNT_NAME, accountName);
Uri rawContactUri = getContentResolver().insert(RawContacts.CONTENT_URI,
values);
long rawContactId = ContentUris.parseId(rawContactUri);
Then insert the name:
values.clear();
values.put(Data.RAW_CONTACT_ID, rawContactId);
values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);
values.put(StructuredName.DISPLAY_NAME, "Some Body");
getContentResolver().insert(Data.CONTENT_URI, values);
You are done.
Now here's a much better way to do the same. Use the
new ContentProviderOperation API, which will ensure that the raw contact and
its name are inserted at the same time.
ArrayList<ContentProviderOperation> ops = Lists.newArrayList();
ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
.withValue(RawContacts.ACCOUNT_TYPE, accountType)
.withValue(RawContacts.ACCOUNT_NAME, accountName)
.build());
ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(Data.RAW_CONTACT_ID, 0)
.withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE)
.withValue(StructuredName.DISPLAY_NAME, "Some Body")
.build());
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
I hope this helps.
