Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic view of a file in an electronic device according to an embodiment of the present invention. Referring to fig. 1, a media database and a file system are included in an electronic device. Files of an electronic device are typically stored in a file system. One or more folders may be included under a root directory of the file system, one or more files may be included under the root directory, and folders and/or files may be included in folders of the root directory, that is, folders and/or files may be included under each folder in the file system.
After the electronic device is powered on, the electronic device may copy the data in the file system to the media database so that the data in the media database is the same as the data in the file system. During the operation of the electronic device, the files in the file system may be updated, for example, files are added to the file system, files are deleted, file names are modified, and the like. After an update to a file in the file system, the updated file is typically synchronized to the media database so that the data in the media database is the same as the data in the file system.
In the application, when the file needs to be inquired in the electronic equipment, a user can input the inquiry keyword, the electronic equipment inquires the file matched with the inquiry keyword in the media database according to the inquiry keyword, and the file is displayed in the electronic equipment. In the process, the files matched with the query key can be queried in the media database in a database query mode, the database query efficiency is high, and the file query efficiency is further improved.
The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may be combined with each other, and the description of the same or similar contents in different embodiments is not repeated.
Fig. 2 is a schematic flowchart of a file query method according to an embodiment of the present invention. Referring to fig. 2, the method may include:
s201, obtaining a file query instruction, wherein the file query instruction comprises query keywords.
The execution subject of the embodiment of the invention can be an electronic device, and can also be a file query device arranged in the electronic device. Alternatively, the file querying device may be implemented by software, or may be implemented by a combination of software and hardware.
Alternatively, the electronic device may have one or more processors, memories, an input unit, and a display unit. For example, the electronic device may be a mobile phone, a tablet computer, or the like.
Optionally, the electronic device may display a file query page, where the file query page includes a query input box and a query icon, a user may input a query keyword in the query input box and click the query icon, and the electronic device may generate a file query instruction according to an operation input by the user, so that the electronic device obtains the file query instruction.
For example, when the system of the electronic device is an Android system, an event listener onquerytextchange of the Android system may listen to whether information input in the query input box is changed and whether information input in the query input box is empty. The event listener onQueryTextSubmit may listen for whether the query icon is clicked. When onQuertyTextChange monitors that the information in the query input box changes and is not empty, and onQuertyTextSubmit monitors that the query icon is clicked, a file query instruction is generated. In this way, when the information in the query input box is not changed or the information in the query input box is queried, even if the onQueryTextSubmit monitors that the query icon is clicked, a file query instruction is not generated, and unnecessary file queries can be avoided.
Optionally, the query keyword may be a file name of the file to be queried, or the query keyword may be a partial character in the file name of the file to be queried, where the partial character may be a partial continuous character in the file name of the file to be queried.
For example, when the user needs to query a file with a file name of 123abcd, the user may input a query keyword 123abcd, or the user may input query keywords 123, 23ab, abcd, and the like.
S202, according to the query instruction, querying a first file corresponding to the query keyword in the media database.
The file name of the first file comprises a query keyword.
Optionally, the number of the first files may be one or more.
Optionally, the file name of the first file is the same as the query keyword, or the query keyword is a part of the file name of the first file.
Optionally, the first file corresponding to the query keyword may be queried in the media database through the following feasible implementation manners: and determining a query statement corresponding to the query keyword, and executing a first query operation in the media database according to the query statement to acquire a first file.
For example, when the media database is a Structured Query Language (SQL) database, then the Query statement is an SQL Query statement.
Optionally, after the file query is completed in the media database, the media database may return a cursor, where the cursor includes the first file.
S203, displaying the first file in the electronic equipment.
Optionally, the file information of the first file may also be acquired, and the file information of the first file is displayed.
Optionally, the file information may include path information of the file, a last modification time of the file, a size of the file, a type of the file, and the like.
Optionally, after the electronic device completes querying all the files in the media database, the electronic device may determine to obtain the first file. That is, after the electronic device queries all the first files, the first files are displayed.
According to the file query method provided by the embodiment of the invention, after the electronic equipment receives the file query instruction comprising the query keyword, the first file corresponding to the query keyword can be queried in the media database according to the query instruction, and the first file is displayed in the electronic equipment. In the process, the files matched with the query key can be queried in the media database in a database query mode, the database query efficiency is high, and the file query efficiency is further improved.
In an actual application process, after the electronic device is started, the electronic device copies data in the file system to the media database, so that the data in the media database is the same as the data in the file system. However, during the operation of the electronic device, the files in the file system may be updated (e.g., files are added, deleted, modified, etc.), and after the files in the file system are updated, the updated files may not be synchronized to the media database, so that the files in the media database are not identical to the files in the file system. Even if the files in the media database and the files in the file system have different parts, the files in the media database and the files in the file system are mostly identical, for example, the files in the media database and the files in the file system have 99.9% of the same files, and have 0.1% of the same files.
For example, when a user uses an application installed in an electronic device, the application generates a new file, the new file is stored in a file system, and if the application does not trigger synchronization of the new file to a media database, the files in the media database and the files in the file system are not identical.
In order to return a correct file query result to a user when the files in the media database are not identical to the files in the file system, the file query can be performed in the media database and the file system at the same time. This file query method is explained below by the embodiment shown in fig. 3.
Fig. 3 is a schematic flowchart of another file query method according to an embodiment of the present application. Referring to fig. 3, the method may include:
s301, a file query instruction is obtained, and the file query instruction comprises query keywords.
It should be noted that the execution process of S301 may refer to the execution process of S201, and is not described herein again.
S302, according to the query instruction, querying a first file corresponding to the query keyword in the media database.
It should be noted that the execution process of S301 may refer to the execution process of S201, and is not described herein again.
It should be noted that the first file may not be queried in S302, in which case S303 may not be executed.
And S303, if the first file and the displayed second file are not overlapped, displaying the first file.
Optionally, if the first file is not in the preset set, adding the first file to the preset set; and displaying the files in the preset set. If the file information of the first file is different from the file information of all the files in the preset set, the first file is not in the preset set; wherein the file information includes a file name and a path.
Wherein the file information includes path information and a file name. Of course, the file information may also include other content, for example, the file information may also include the last modification time of the file, the size of the file, the type of the file, and the like.
Initially, the preset set is empty. In the file query process, the first file and the second file may be added to a preset set. Thus, in performing S303, one or more second files may already exist in the preset set.
The files in the preset set are file query results, that is, the files in the preset set are files that have been currently displayed in the electronic device.
Optionally, the file information of the first file may be compared with the file information of each file in the preset set, and if the file information of the first file is different from the file information of each file in the preset set, the first file is added to the preset set.
Optionally, after the first file is added to the preset set, the preset set is updated. After the preset set is updated, the displayed file is updated in the electronic equipment. That is, after the preset set is updated, the files in the updated preset set are displayed in the electronic device.
Optionally, when the electronic device displays the files in the preset set, file information of the files may also be displayed.
S304, traversing the second file corresponding to the query keyword in the file system according to the query instruction.
Optionally, all the files in the file system may be obtained first, and whether the file name of each file includes the query keyword is judged respectively, and if yes, the file is determined as the second file.
Optionally, because the file system includes a plurality of files, when the electronic device determines that the file name of one file includes the query keyword, the file is determined as a second file. That is, in the process of querying a file in the file system, the number of second files obtained by querying may be increased continuously.
For example, in the 1 st second of the file query, a file with a file name including the query keyword may be queried, and the file is determined to be a second file, where the number of the second files obtained by the query is 1. In the 5 th second of file query, a file with a file name including the query keyword may be queried, and the file is also determined as a second file, at this time, the number of the second files obtained by query is 2.
For example, when the system of the electronic device is an Android system, all folders and files under one folder can be acquired by a file. After a folder is obtained from the folder, the file and/or the folder can be obtained from the folder through the listFile operation, and the above process is repeated until all the files in the file system are obtained.
S305, if the second file is not overlapped with the displayed first file, displaying the second file.
In the process of file query, since the queried second file may be updated, in order to improve the file query efficiency, after a new second file is obtained by query, it is determined whether the new second file is overlapped with the displayed first file. That is, S304 and S305 may be executed in parallel.
It should be noted that, in the process of querying the file, the queried second file may be updated, so that a new second file may be queried at different times, and in order to improve the efficiency of returning the query result to the user, each time a new second file is determined to be obtained, the new second file is displayed in the electronic device.
For example, in the process of file query, a second file may be obtained in 2 seconds, and the second file may be displayed in 2 seconds. If a second file is queried again at the 10 th second, the second file can be displayed at the 10 th second.
Optionally, if the second file is not in the preset set, adding the second file to the preset set; and displaying the files in the preset set. If the file information of the second file is different from the file information of all the files in the preset set, the second file is not in the preset set; wherein the file information includes a file name and a path.
Initially, the preset set is empty. In the file query process, the first file and the second file may be added to a preset set. Thus, in executing S305, one or more first files may already exist in the preset set.
Optionally, the file information of the second file may be compared with the file information of each file in the preset set, and if the file information of the second file is different from the file information of each file in the preset set, the second file is added to the preset set.
Optionally, after the second file is added to the preset set, the preset set is updated. After the update of the pre-assembly set occurs, the displayed file is updated in the electronic equipment. That is, after the preset set is updated, the files in the updated preset set are displayed in the electronic device.
Optionally, when the electronic device displays the files in the preset set, file information of the files may also be displayed.
Optionally, after the file query instruction is obtained, the first thread and the second thread may be started, and the first thread and the second thread may be executed in parallel by executing S302 to S303 through the first thread and executing S304 to S305 through the second thread.
In the embodiment shown in fig. 3, after the file query instruction is obtained, file query is performed in the media database and the file system at the same time, and the file matched with the query keyword can be quickly queried and obtained in the media database, and the file matched with the query keyword is displayed to the user. Meanwhile, file query is carried out in the file system, so that the problem that all files matched with the query keywords cannot be obtained through query when the data in the media database is not identical to the data in the file system can be prevented. That is, with the embodiment shown in fig. 3, not only the efficiency of returning the file query result (the file matched with the query keyword) to the user can be improved, but also the correct file query result can be ensured to be returned to the user.
The method shown in the embodiment of fig. 3 will be described in detail by specific examples with reference to fig. 4.
Fig. 4 is a schematic diagram of a file query process according to an embodiment of the present invention. See fig. 4, including interface 401-interface 403.
At time 1, please refer to interface 401, when a user needs to query a file in an electronic device, the user may open a file query interface of the electronic device. The file query interface comprises an input box, a query icon and a queried file list. Initially, the queried file list is empty. The user may enter a query keyword (abc) in the search box and click on the "query" icon. At this time, the preset set is empty, and the first file and the second file are obtained without inquiry.
After the user clicks the query icon, the electronic equipment obtains a file query instruction, and the file query instruction comprises query keywords (abc). After the file query instruction is obtained, the electronic equipment starts a first thread and a second thread, the first thread and the second thread are executed in parallel, the electronic equipment queries files in the media database through the first thread and queries files in the file system through the second thread.
At time 2, please refer to the interface 402, the electronic device queries the media database through the first thread to obtain three files, and queries the file system through the second thread to obtain one file. Assuming that one file queried in the file system is the same as one of the three files queried in the media database, the three files queried in the media database are displayed in the file list. At this time, the first file is obtained by querying the media database through the first thread, the second file is obtained by querying the file system through the second thread, and the preset set includes three files obtained by querying the media database through the first thread.
At time 3, please refer to the interface 403, the electronic device queries three files in the system file through the second thread, the file names and the path information of the files are as shown in fig. 4, and since three of the four files obtained by querying in the file system are the same as the three files obtained by querying in the media database, one of the different files is added to the preset set and additionally displayed in the file list. At this time, the first file is obtained by querying the media database through the first thread. The second file is inquired in the file system through a second thread to obtain four files, and the preset set comprises the four files inquired in the media database through the second thread.
In the embodiment shown in fig. 4, not only the efficiency of returning the file query result (target file) to the user can be improved, but also the correct file query result can be ensured to be returned to the user.
