如何使用ContactsContract更新所有字段

Question

我有个问题。

在我的应用程序中，最终用户将输入用户名、电子邮件地址和城市。现在，如果用户输入的电子邮件存在，则应该运行更新查询。字段用户名和城市应该在他的手机里更新。如果该电子邮件不存在，则应创建一个新的联系人。

现在我可以创建一个新条目，但不知何故更新查询不能正常工作。也许我犯了个大错。

需要帮助。

我正在发布我的createContact和updateContact代码。Create contact工作正常。它能够插入新的联系人。

//创建联系人

ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
    ops.add(ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI)
        .withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, null)
        .withValue(ContactsContract.RawContacts.ACCOUNT_NAME, null)
        .build());

    //------------------------------------------------------ Names

    if(!DisplayName.equals("") ) {
        ops.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, DisplayName)
                .build());
    }                       


    if(emailID != null) {
        ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)
                .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
                .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE)
                .withValue(ContactsContract.CommonDataKinds.Email.DATA, emailID)
                .withValue(ContactsContract.CommonDataKinds.Email.TYPE, ContactsContract.CommonDataKinds.Email.TYPE_WORK)
                .build());
    }


   if(!street.equals("") || !city.equals("") || !state.equals("") || !zipcode.equals("")) {
        ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)
                .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
                .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE)
                .withValue(ContactsContract.CommonDataKinds.StructuredPostal.STREET, street)

                .withValue(ContactsContract.CommonDataKinds.StructuredPostal.CITY, city)
                .withValue(ContactsContract.CommonDataKinds.StructuredPostal.TYPE, ContactsContract.CommonDataKinds.StructuredPostal.TYPE_WORK)
                .withValue(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE, zipcode)
                .withValue(ContactsContract.CommonDataKinds.StructuredPostal.TYPE, ContactsContract.CommonDataKinds.StructuredPostal.TYPE_WORK)
                .withValue(ContactsContract.CommonDataKinds.StructuredPostal.REGION, state)
                .withValue(ContactsContract.CommonDataKinds.StructuredPostal.TYPE, ContactsContract.CommonDataKinds.StructuredPostal.TYPE_WORK)
                .build());
    }

//更新联系人

//insert or update

Intent intent = new Intent(Intent.ACTION_INSERT_OR_EDIT);
                intent.setType(ContactsContract.Contacts.CONTENT_TYPE);

                intent.putExtra(ContactsContract.Intents.Insert.NAME, fullname);
intent.putExtra(ContactsContract.Intents.Insert.PHONE,phnumber);

                intent.putExtra(ContactsContract.Intents.Insert.EMAIL, email);
                intent.putExtra(ContactsContract.Intents.Insert.NOTES,
                        "Imported from moodle");
                intent.putExtra(ContactsContract.Intents.Insert.POSTAL, city
                        + " " + country);

                startActivityForResult(intent, 1);



protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            switch (requestCode) {
            case 1:
                if (requestCode == 1) {

                }
                super.onActivityResult(requestCode, resultCode, data);
            }
        }
    }

我在这里放了update方法的代码，根据你的需要进行修改。

public int updateContact(Contact contact) {
    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues values = new ContentValues();
    values.put(KEY_NAME, contact.getName());
    values.put(KEY_PH_NO, contact.getPhoneNumber());

    // updating row
    return db.update(TABLE_CONTACTS, values, KEY_ID + " = ?",
            new String[] { String.valueOf(contact.getID()) });
}
