ICU (International Components for Unicode, the international assembly of Unified coding) be that engine module is supported in internationalization/localization, be built-in with Chinese support, can change the compiling configuration and add Chinese support, the collation rule adopts phonetic, Chinese character can use Pinyin sorting like this, but can't accomplish Chinese and English hybrid-sorting.
At first will revise bottom ICU storehouse, database sort and application program retrieval are all based on this.A big table is used in the phonetic transcriptions of Chinese characters ordering, the inside has sequenced order to Chinese character more than 20,000 1 thousand, insert respectively alphabetical a-z and A-Z inside, be placed on the place of "＜huge legendary turtle＜Ao＜b＜B＜eight＜Ba " such as alphabetical b and B, one field is set up index has been exactly Chinese and English hybrid-sorting to database automatically like this, and the sort algorithm time efficiency is the constant level.
Need to open the translit function of ICU4c (ICU4c is the version of ICU under the C/C++ platform), realize that Chinese is to the conversion of phonetic.
The contact person provides the contact list 402 of device 404 management take display Name field (display_name) as index, the music table 502 that provides device 504 management with media is take title (title) as index, and contact person and music have all realized the Chinese and English hybrid-sorting of database level like this.
The Chinese character string coupling Android2.1 system of contact person and music carries, need here to add that character a-z locates fast, the contact person also will add and carry out the retrieval of phonetic retrieval and initial, and both all do not need the data database table structure is changed, and only need to revise partial logic.
Retrieval to the contact person is to provide the name look-up table (name_lookup) of device (ContactsProvider) 404 management to realize by inquiring contactor, all search keys preserved in field specification assumed name's word (normalized_name) of name look-up table, a few row data of many increases in the name look-up table are with regard to many several keywords.Automatically according to display name (display_name) field generation phonetic spelling and the initial simplicity word string of contact list 402 (contacts), then these word strings are all added in the name look-up table in the time of interpolation or renewal contact person.Contact application just can be come quickly positioning contact person by character a-z automatically, can also carry out the retrieval of phonetic retrieval and initial.406 couples of contact names of structuring name row processor (Structured NameRowHandler) carry out structuring and process, and add the name look-up table to and make up the name look-up table that device (NameLookupBuilder) 408 makes up, 410 pairs of names of name normalizer (NameNormalizer) are standardized, and SQLite database 412 is used for preserving associated person information.
In this embodiment, with reference to figure 5, the location is just passable fast only need to add character a-z to the retrieval of music.This is to provide the title_key field of the music table 502 of device 504 (MediaProvider) management to realize by the inquiry media.Add or automatically obtain sortkey according to arrangement (collation) method of title field by ICU when upgrading music, be kept in the title_key field with 16 system forms.In music application a-z is also generated sortkey equally and mate music title, so just can locate fast.Media stored audio program 506 is used for the stored audio file, obtain arrangement key word (CollationKey) from data base tool (databaseUtils) 508, data base tool (databaseUtils) 508 obtains the arrangement key word from ICU reorganizer (Collator) 510, and SQLite database 512 is used for preserving media data.
In technique scheme, the location is just passable fast only need to add character a-z to the retrieval of music.This is to realize by the title_key field that the audio that inquiry media database ISP manages shows.Add or automatically obtain sortkey according to the collation method of title field by icu when upgrading music, be kept in the title_key field with 16 system forms.We also generate sortkey in music application to a-z and mate music title equally, so just can locate fast.
According to technique scheme, consider Chinese factor, utilize order module to carry out the Chinese phonetic alphabet ordering of Chinese contact person and Chinese music, and energy and English hybrid-sorting; Can realize that by change contact database ISP/media database ISP input character a-z comes quickly positioning contact person and music, the contact person can also carry out phonetic retrieval or initial retrieval by retrieval module.Reduced greatly the complexity of upper level applications contact application and music application, improved effectiveness of performance, made the ordering of based on database and the performance of searching system reach best.
Chinese contact person and Chinese music can sort according to the Chinese phonetic alphabet, and energy and English hybrid-sorting, can come quickly positioning contact person and music by input character a-z, and the contact person can also carry out phonetic retrieval or initial retrieval.
At present, the related platform solution is that database does not have Chinese and English hybrid-sorting, all reads up to ten thousand by application program at every turn and all is converted to phonetic by third party library behind the record, then in internal memory ordering and retrieval, time-consumingly takes the space and application logic is complicated.
And technical scheme according to the present invention sequences order when adding record by database automatically, and ordering is the constant time level, and retrieval is also finished by database; Support storehouse and database section logic by a small amount of modification bottom icu, reduced greatly the complexity of upper level applications Contacts and Music and improved effectiveness of performance, the performance of this scheme is best.
Technical scheme according to the present invention is the universal solution of the mobile-terminal platform of Android system, Symbian system, Windows Mobile system for example, and all large-scale tabulations by the database storage all can come quicksort and retrieval with this scheme.
