我的应用程序必须更新给定联系人的组织属性。如果联系人已经填充了组织属性，则此方法可以正常工作，但如果组织标记为空，则返回 NullPointerException。

public boolean updateOrganizationFromContact(String contactId, String companyName){

//Get contact from ContactList
    boolean foundContact = false;
    int i = -1;
    while(!foundContact && i<contactList.size()){
        i++;
        foundItem = contactId.equals(contactList.get(i).getId());
    }
//Check if Contact has already a filled up organization-tag
    if (contactList.get(i).getOrganization().hasEntry()){
//if yes, update:
        ContentResolver contentResolver = context.getContentResolver();
        String where = ContactsContract.Data.CONTACT_ID + " = ? AND " +
                       ContactsContract.Data.MIMETYPE + " = ?";
        String[] whereParameters = new String[]{contactId, 
            ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE};
        ContentValues values = new ContentValues();
            values.put(ContactsContract.CommonDataKinds.Organization.DATA, companyName);
        contentResolver.update(ContactsContract.Data.CONTENT_URI, values, where, whereParameters);
        return true;
    } else {
//if not, go to next method:
        return createOrganizationFromContact(contactId, companyName);
    }
}

private boolean createOrganizationFromContact(String contactId, String companyName) {
    ContentResolver contentResolver = context.getContentResolver();
    ContentValues values = new ContentValues();
    values.put(ContactsContract.Data.CONTACT_ID, contactId);
    values.put(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE);
    values.put(ContactsContract.CommonDataKinds.Organization.DATA, companyName);

//now this is the line with the NPE (line 212):
    Uri uri = contentResolver.insert(ContactsContract.Data.CONTENT_URI, values);

    return true;
}

结果堆栈跟踪：

我认为缺少一些 ContentValues。但我找不到任何用于更新联系人组织的文档/示例。有什么帮助吗？

发现我对 RawContacts 的理解很差。您必须先创建 RawContact，然后参考它添加数据。要将新的 RawContact 链接到现有的，需要像 DisplayName 这样的 Datafiled。ContactsApp 会自动进行映射，但您必须信任。

这是解决方案，灵感来自 Android 示例中的 ContactsManager 应用程序

    private boolean createOrganizationFromContact(Contact contact, String companyName) {
        try {
        ContentResolver contentResolver = context.getContentResolver();
            ArrayList<ContentProviderOperation> operations = new ArrayList<ContentProviderOperation>();
            operations.add(ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI)
                .withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, context.getResources().getString(R.string.accounttype))
                .withValue(ContactsContract.RawContacts.ACCOUNT_NAME, context.getResources().getString(R.string.accountusername))
                .build());
        operations.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)
                .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
                .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE)
                .withValue(ContactsContract.CommonDataKinds.Organization.DATA, companyName)
                .build());
        operations.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)
                .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
                .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE)
                .withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME, contact.getDisplayName())
                .build());
        contentResolver.applyBatch(ContactsContract.AUTHORITY, operations);
        } catch (RemoteException e) {
            e.printStackTrace();
            return false;
        } catch (OperationApplicationException e) {
            e.printStackTrace();
            return false;
        }
        return true;
    }
}
