Question

我正在尝试从手机通讯录中删除联系人。该联系人会从手机通讯录中删除，但不会从服务器端（Google通讯录）中删除，当Google联系人同步触发时，该联系人将重新显示已删除的联系人。以下是我的代码。

public static void deleteContact(long rawid, ContentResolver contentResolver) {
    ArrayList<ContentProviderOperation> ops = new ArrayList<>();
    Uri uri = ContactsContract.RawContacts.CONTENT_URI
            .buildUpon()
            .appendQueryParameter(
                    ContactsContract.CALLER_IS_SYNCADAPTER,
                    "true")
            .build();
    ops.add(ContentProviderOperation
            .newDelete(uri)
            .withSelection(
                    ContactsContract.RawContacts._ID + " = ?",
                    new String[]{Long.toString(rawid)})
            .build());

    try {
        contentResolver.applyBatch(
                ContactsContract.AUTHORITY,
                ops);
    } catch (RemoteException | OperationApplicationException e) {
        e.printStackTrace();
    }
}

您应该在代码中使用ContactsContract.CALLER_IS_SYNCADAPTER作为false。设置为true时，将从数据库中永久删除联系人。但是当下一次同步发生时，联系人将被同步回来。 Google同步检查已删除的联系人的方式是使用已删除的标记，仅当您将ContactsContract.CALLER_IS_SYNCADAPTER设置为false时才会设置该标记。以下是ContactsProvider类的代码片段（联系人数据存储区的contentprovider）

if (callerIsSyncAdapter || rawContactIsLocal(rawContactId)) {
    // When a raw contact is deleted, a SQLite trigger deletes the parent contact.
    // TODO: all contact deletes was consolidated into ContactTableUtil but this one can't
    // because it's in a trigger.  Consider removing trigger and replacing with java code.
    // This has to happen before the raw contact is deleted since it relies on the number
    // of raw contacts.
    db.delete(Tables.PRESENCE, PresenceColumns.RAW_CONTACT_ID + "=" + rawContactId, null);
    count = db.delete(Tables.RAW_CONTACTS, RawContacts._ID + "=" + rawContactId, null);
    mTransactionContext.get().markRawContactChangedOrDeletedOrInserted(rawContactId);
} else {
    count = markRawContactAsDeleted(db, rawContactId, callerIsSyncAdapter);
}
