Android利用ContentProviderOperation添加联系人

Android添加联系人有两种方式：

1. 直接调用插入语句，先插入一个空Item，得到一个id，然后给这个id对应的插入其他信息，如姓名，号码，邮件等；

2. 利用ContentProviderOperation， 在系统应用Phonebook中就是采用这种方式， 代码如下：

实现了插入姓名，号码以及头像。

    private boolean saveUpdatedPhoto(long rawContactId, File photoFile) {
        final Uri outputUri = Uri.withAppendedPath(ContentUris.withAppendedId(
                RawContacts.CONTENT_URI, rawContactId),
                RawContacts.DisplayPhoto.CONTENT_DIRECTORY);
        boolean result = false;
        try {
            final FileOutputStream outputStream = getContentResolver()
                    .openAssetFileDescriptor(outputUri, "rw")
                    .createOutputStream();
            try {
                final FileInputStream inputStream = new FileInputStream(
                        photoFile);
                try {
                    final byte[] buffer = new byte[16 * 1024];
                    int length;
                    int totalLength = 0;
                    while ((length = inputStream.read(buffer)) > 0) {
                        outputStream.write(buffer, 0, length);
                        totalLength += length;
                    }
                    result = true;
                } finally {
                    inputStream.close();
                }
            } finally {
                outputStream.close();
                photoFile.delete();
            }
        } catch (IOException e) {
            result = false;
        }
        return result;
    }

    public void addContact(String name, CharSequence phoneNumber1,
            CharSequence phoneNumber2, String email1, String email2, String im,
            String nickname) {
        final ArrayList<ContentProviderOperation> operationList = new ArrayList<ContentProviderOperation>();
        ContentProviderOperation.Builder builder = null;
        int rawContactIndex = 0;

        builder = ContentProviderOperation.newInsert(RawContacts.CONTENT_URI);

            builder.withValueBackReference(Email.RAW_CONTACT_ID,
                    rawContactIndex);

        }

        if (!TextUtils.isEmpty(email2)) {

            builder.withValueBackReference(Email.RAW_CONTACT_ID,

            builder.withValue(Email.TYPE, Email.TYPE_HOME);
            builder.withValue(Email.DATA, email2);
            operationList.add(builder.build());
        }

        // Add IM info.
        builder = ContentProviderOperation.newInsert(Data.CONTENT_URI);

        builder.withValue(Im.DATA, im);
        operationList.add(builder.build());

        // Add Nickname info.
        builder = ContentProviderOperation.newInsert(Data.CONTENT_URI);
        builder.withValueBackReference(Nickname.RAW_CONTACT_ID, rawContactIndex);
        builder.withValue(Data.MIMETYPE, Nickname.CONTENT_ITEM_TYPE);
        builder.withValue(Nickname.TYPE, Nickname.TYPE_INITIALS);
        builder.withValue(Nickname.DATA, nickname);
        operationList.add(builder.build());

        try {
            getContentResolver().applyBatch(ContactsContract.AUTHORITY,
                    operationList);
            // Get raw_contact_id
            Cursor cc = getContentResolver().query(RawContacts.CONTENT_URI,
                    null, "display_name=?", new String[] { name }, null);
            cc.moveToFirst();
            // Insert photo for the contact.
            saveUpdatedPhoto(cc.getLong(cc.getColumnIndex("_id")), new File(
                    "/sdcard/DCIM/Camera/ContactPhoto-IMG_19700104_013154.jpg"));
        } catch (RemoteException e) {
        } catch (OperationApplicationException e) {
        }
    }

基本思路是先插入除头像以外的其他信息，然后获得raw_contact_id,再给这个id插入头像，具体方法是saveUpdatedPhoto（）。

Note：本人不太清楚能不能像插入姓名一样插入头像，所以才想出了这么一招，如果谁有更好的方法，不需要查询获得id就可以直接插入头像，共享一哈。
