如何从Android通讯录中的联系人ID获取只读帐户名称

Question

我正在将帐户名称从列表传递给此方法。现在我想知道这些帐户名称中的哪些在联系人表中是只读的，所以我只迭代游标一次以从原始游标获取联系人 ID。获得contact_id后，我正在使用手机光标检查给定的ID是否为只读，但我无法做到这一点。请看下面

private void displayAllContactsByType(String accountName) {
Cursor rawCursor,phones = null;
rawCursor = cResolver.query(
ContactsContract.RawContacts.CONTENT_URI,
new String[]{ContactsContract.RawContacts.CONTACT_ID},
ContactsContract.RawContacts.ACCOUNT_NAME + "= ?",
new String[]{accountName},
null);

int contactIdColumn = rawCursor.getColumnIndex(ContactsContract.RawContacts.CONTACT_ID);
int rawCursorCount = rawCursor.getCount();

Utils.Log("Account Name",  accountName);
Utils.Log("Raw Size", " " + rawCursorCount);
rawCursor.moveToFirst();
Long contactId = rawCursor.getLong(contactIdColumn);

phones = cResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND "+ContactsContract.RawContacts.ACCOUNT_NAME + "= ?",
new String[]{String.valueOf(contactId),accountName},
null);
phones.moveToFirst();


String isReadOnly= phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.IS_READ_ONLY));
Utils.Log("Raw Size", isReadOnly);

}

您不必检查帐户的联系人即可检查，只需遍历设备上的 SyncAdapter，并检查其属性：

final SyncAdapterType[] syncs = ContentResolver.getSyncAdapterTypes();
for (SyncAdapterType sync : syncs) {
Log.d(TAG, "found SyncAdapter: " + sync.accountType);
if (ContactsContract.AUTHORITY.equals(sync.authority)) {
Log.d(TAG, "SyncAdapter supports contacts: " + sync.accountType);
boolean readOnly = !sync.supportsUploading();
Log.d(TAG, "SyncAdapter read-only mode: " + readOnly);
if (readOnly) {
// we'll now get a list of all accounts under that accountType:
Account[] accounts = AccountManager.get(this).getAccountsByType(sync.accountType);
for (Account account : accounts) {
Log.d(TAG, account.type + " / " + account.name);
}
}
}
}

希望这有帮助。
