Specifically, fig. 1 shows a flowchart of a file query method provided in an embodiment of the present application, where the file query method is applied to a terminal device, and includes:

step S101, when detecting that a first query statement of a specified application program for querying a multimedia database contains a preset statement, determining a specified file type corresponding to the query.

In the embodiment of the present application, the specific application may be set according to an actual application scenario, for example, the specific application may be a social type application, an album, an entertainment type application, and the like.

In some embodiments, the preset statement may indicate a partial query condition of the specified application, for example, the specified application may query folders existing in the multimedia database first and then query files of a specific type in each folder; then, the preset statement may instruct the specified application to query folders existing in the multimedia database, that is, when it is detected that the first query statement for querying the multimedia database by the specified application contains the preset statement, the specified application may be considered to start to perform an operation of querying the multimedia database for a specific type of file.

In the embodiment of the present application, the specified file type may include a document, a picture, a video, an audio, and the like. The specified file type can be determined by the extension of the file, wherein one or more extensions can be used as a specified file type.

Specifically, the determining of the specified file type corresponding to the query may be implemented by specifying a query statement for querying the multimedia database by an application, where the query statement may be a first query statement or another query statement; further, this may be accomplished based on operations performed by a given application prior to querying the multimedia database. For example, a specified file type corresponding to the query may be determined based on a user operation at the specified application.

In some embodiments, the terminal device may monitor in real time whether the first query statement for querying the multimedia database by the specified application contains a preset statement. Of course, in some embodiments, the terminal device may also listen at a certain period.

In some embodiments, the determining, when it is detected that a first query statement for a specific application to query a multimedia database contains a preset statement, a specific file type corresponding to the query includes:

when detecting that a first query statement of a specified application program for querying a multimedia database contains bucket _ id and/or bucket _ display _ name, determining a specified file type corresponding to the query.

The bucket _ id and/or the bucket _ display _ name may be used to determine that the specified application starts to perform an operation of querying a multimedia database for a file of a specific type. The bucket _ id and/or the bucket _ display _ name may be used to identify a folder in the multimedia database, that is, when it is detected that a first query statement for querying the multimedia database by a specific application includes the bucket _ id and/or the bucket _ display _ name, the specific application may be considered to query the folder existing in the multimedia database. At this time, based on the specified file type corresponding to the query, the subsequent further query may be performed, for example, user-defined information of the file of the specified file type is queried by the user, so as to provide a richer and more comprehensive query result for the specified application program.

And step S102, inquiring a preset label corresponding to the specified file type in the multimedia database.

In this embodiment of the application, the preset tag corresponding to the specified file type may be a tag corresponding to a file of which the file type is the specified file type. The preset tag may be pre-identified by a user. Specifically, the user may identify the file of which the file type is the specified file type through the specified application program, or may identify the file through another application program other than the specified application program.

In some embodiments, the execution of step S102 may be performed by the system of the terminal device, rather than by specifying the application itself. At this time, the specific implementation manner of the step may be defined by the system, and is not affected by the designated application program itself, that is, the embodiment may be applied to different designated application programs. Of course, in other embodiments, step S102 may be performed by the designated application itself.

In some embodiments, the preset tag may be saved in the multimedia database in a preset manner, for example, a part of the tag representing the file may be added to the storage structure of the file. In addition, the labels corresponding to the files can be stored in a multimedia database in a list or the like.

As shown in fig. 2, in some embodiments, the step S102 may specifically include:

step S201, replacing the query condition of the first query statement with a query first attribute to a query second attribute to obtain a second query statement, wherein the first attribute identifies a folder in the multimedia database, and the second attribute identifies a preset tag corresponding to the specified file type;

step S202, according to the second query statement, querying a preset label corresponding to the specified file type in the multimedia database.

In this embodiment of the application, the first attribute may be used to identify a folder in the multimedia database, and for example, the first attribute may be a bucket _ id bucket, a display _ name, and/or a number of the folder. And the second attribute may be determined according to a storage manner of the preset tag.

For example, in some embodiments, if the bucket _ id and the bucket _ display _ name may be used to identify a folder in the multimedia database, and the storage structure of the preset tag is predefined as a label number, the second attribute may include a label, the first attribute includes the bucket _ id and the bucket _ display _ name, the query condition in the first query statement may include a SELECT bucket _ id and a bucket _ display _ name, and the query condition in the second query statement may include a SELECT label.

Through step S201 and step S202, the inquiry of the preset label can be realized through simple replacement, the expansibility is better, and the usability is stronger. Moreover, the query mode of the preset label is unified with the query mode of the folder directory, so that the preset label and the folder directory can be conveniently combined in a follow-up mode.

Step S103, acquiring a folder directory of the file with the file type being the specified file type in the multimedia database.

In the embodiment of the present application, the folder directory including the file with the file type as the specified file type may be queried in various ways, for example, the folders included in the multimedia database may be queried, and then it is detected whether each folder includes the file with the file type as the specified file type. Of course, it is also possible to detect a file in the multimedia database whose file type is the specified file type, and determine a folder directory containing files whose file types are the specified file type according to the storage path.

In some embodiments, the obtaining a folder directory of a file in the multimedia database, the file type of which is the specified file type, includes:

inquiring folders contained in the multimedia database according to the first inquiry statement;

and detecting whether each folder contains files with the file types as the specified file types or not so as to obtain a folder directory of the files with the file types as the specified file types in the multimedia database.

The detecting whether each folder contains a file of which the file type is the specified file type may include:

and detecting whether each folder contains a file with the file type as the specified file type, and acquiring the file with the file type as the specified file type in each folder.

In some embodiments, after obtaining the file with the file type of the specified file type in each folder, the information of the queried files with all file types of the specified file type can be returned to the specified application program; and if an instruction for displaying the file with the file type as the specified file type is detected, displaying the inquired files with all file types as the specified file type according to the specified display mode.

And step S104, combining the preset label and the folder directory to obtain a target directory.

In some embodiments of the present application, a storage manner and a form of the preset tag may be preset, and a manner of querying the preset tag may be preset, so that the form of the preset tag obtained by querying and the form of the folder directory are unified, for example, so that the preset tag and the folder directory may be more conveniently merged.

In some embodiments, the merging the preset tag and the folder directory to obtain the target directory includes:

and merging the preset label and the folder directory through MergeCursor to obtain a target directory.

The merge of the target directory and the target directory may be performed by merging the preset tag and the folder directory with the merger, where the merge may be referred to as cursor merge. It can be considered that, in the target directory, the preset tag can be considered as a virtual folder directory.

Step S105, returning the target directory to the specified application program.

It should be noted that, after the specified application program obtains the target directory, whether the target directory is presented or not may depend on the setting of the specified application program, the operation of the user, and other factors.

For example, in some embodiments, it may be that upon detecting that a user clicks a particular virtual key (e.g., a virtual key indicating the addition of a picture, video, document, etc.) in a specified application, the specified application queries the multimedia database for a file of a specified file type; when the specified application program obtains the target directory, the target directory of the file with the file type being the specified file type can be displayed on a display screen of the terminal equipment, and the user further searches the desired file according to the target directory. In addition, when the specified application program obtains the target directory, a file with a file type of the specified file type may also be obtained at the same time, at this time, an overall list of files with a file type of the specified file type may be presented to a user according to a specific display manner, and since there are many files in the terminal device, at this time, a virtual key for switching to the target directory displaying the file with a file type of the specified file type may also be provided to the user, so that the user may switch the interface of the specified application program to the interface presenting the target directory.

It should be noted that, in the embodiment of the present application, the folder directory that includes the file with the file type being the specified file type generally includes all the files with the file type being the specified file type obtained through query, and the file corresponding to the preset tag generally exists in some folder directories. That is, the file corresponding to the preset tag is generally a repeated representation of at least a part of files of which the file types under the folder directory are the specified file types. Through the repeated presentation, the user can quickly find some information marked by self definition, namely preset label information, so that the user-defined label is fully utilized, and the user can conveniently and quickly find some files marked with the label information in a designated application program.

As an illustrative example, as shown in fig. 3, the display interface of the terminal device provided in an embodiment of the present application is a schematic diagram.

The target directory of the file with the picture type can be displayed on a display screen of the terminal device, and a user can further search a desired file according to the target directory. The "school" and the "home" may be preset tags, and the folders 1, 2, and 3 may be folder directories of files in the multimedia database, which include files of which the file types are pictures. The number of files of which the file types are the specified file types, which are contained in the folder directory containing the files of which the file types are the specified file types, and each preset tag can be marked.

In some embodiments, after returning the target directory to the specified application, the file query method may further include:

and if an instruction for displaying the directory list interface of the specified file type is detected, displaying the directory list interface according to the target directory.

The instruction for displaying the directory list interface of the specified file type may be determined based on an operation of a user, and it should be noted that the instruction for displaying the directory list interface of the specified file type may be issued when the user clicks a specific virtual key (such as a virtual key for instructing to add a picture, a video, a document, or the like) in a specified application program, or may be issued according to a subsequent operation of the user after the target directory is obtained, and the issuing timing is not limited herein.

The directory list interface may include information of the target directory, and in addition, the target list interface may display the number of files in which the file types respectively included in each preset tag and each preset folder in the target directory are the designated file types.

In some embodiments, in the target list interface, the arrangement order of each preset tag and each folder directory may be determined according to the sequence of the latest usage time of each preset tag and each folder directory.

In some embodiments, after querying the preset tag corresponding to the specified file type in the multimedia database, the method further includes:

inquiring a file corresponding to the preset label;

and if an instruction for displaying the file corresponding to the preset label is detected, displaying the file corresponding to the preset label according to a preset display mode.

In the embodiment of the present application, it should be noted that the time sequence of querying the file corresponding to the preset tag and detecting the instruction for displaying the file corresponding to the preset tag is not limited herein. In some embodiments, after an instruction to display a file corresponding to the preset tag is detected, the file corresponding to the preset tag may be queried; in other embodiments, the file corresponding to the preset tag may be queried first, and if an instruction to display the file corresponding to the preset tag is detected subsequently, the file corresponding to the preset tag may be displayed according to a preset display manner and the file corresponding to the preset tag that is queried in advance.

In the embodiment of the application, when a first query statement for a specified application program to query a multimedia database is detected to contain a preset statement, a specified file type corresponding to the query is determined, and the multimedia database is queried, wherein the preset label corresponding to the specified file type can determine the file type which the specified application program wants to query when the specified application program is detected to query the multimedia database for specific content, so as to further execute the operation of querying the multimedia database, wherein the preset label corresponding to the specified file type is operated, and therefore, some labels which are preset for the type of files by a user and other personnel are known; and by combining the preset tag and the folder directory containing the file with the file type of the specified file type to obtain the target directory and returning the target directory to the specified application program, the tag and the folder directory information set by the user can be integrated, and the directory information obtained by the query operation of the application program on the specific file type is expanded, so that the specified application program can provide a more personalized presentation mode for the user in subsequent application, and the user experience is improved.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
