detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

Embodiment one:

Fig. 1 shows the implementation process of the mobile terminal file search method that the first embodiment of the present invention provides, and its process is described in detail as follows:

In step S101, the storage path of the mobile terminal file is obtained.

Specifically, the storage path of the mobile terminal file is obtained, and the obtained storage path is written into a new folder, and the new folder is stored in the root directory of the mobile terminal. The storage path described in this embodiment refers to the absolute path of the file. For example, the good.jpg file in the pictures folder has an absolute path of /media/sdcards/picures/good.jpg instead of a relative path ../good.jpg. According to the storage path, the mobile terminal can quickly obtain the corresponding file.

Further, due to operations such as adding or deleting files by the user, this embodiment also includes:

The stored storage path is updated according to an update instruction, the update instruction being triggered by an update start command input by a user, or automatically triggered according to a configured update time limit.

In the embodiment of the present invention, the update instruction of the storage path in the new folder may be triggered by an update start command actively input by the user, or may be automatically triggered by the system when the update time limit expires according to the configured update time limit.

As an embodiment of the present invention, the user can pre-configure the update time limit of the storage path, for example, it is configured to update once every day, every week, or every 10 days, etc., the system monitors the update time limit in real time, and automatically initiates when the update time limit expires. The update process of the storage path.

In addition, the update startup command described in this embodiment may preferably be: after detecting that the user's touch action on the mobile terminal is a two-point touch and the sliding track is a vertical relative sliding, it is determined whether the vertical relative sliding displacement of the two touch points is greater than Whether the preset first threshold, the distance difference between the final landing points of the two touch points is less than the preset second threshold, and whether the sliding speed of the two touch points is greater than the preset third threshold at the same time; After the touch action is a two-point touch and the sliding trajectory is sliding in opposite directions, it is judged whether the displacements of the two touch points sliding in opposite directions are greater than the preset first threshold at the same time, and whether the distance difference between the final landing points of the two touch points is greater than the preset fourth threshold, and whether the sliding speed of the two touch points is greater than the preset third threshold at the same time, if so (that is, the judgment results of the above three conditions are all "yes"), it is determined to be an update start command; If not (at least one of the judgment results of the above three conditions is "No"), do not execute, and end the current operation.

In step S102, a tree structure index is established according to the storage path.

In this embodiment, a tree structure index is established according to the storage path, for example, there are folders bin, etc, sys, data, root, etc. under the root directory of the mobile terminal, and there are subfolders under the directory, according to Create a tree structure index at the directory level, for example, there are pictures and apps folders under the root file, and there are cards and sdcards directories under pictures, then when building an index, the root node of the tree is root, and there are branches pictures and apps, and Pictures have branch cards and sdcards.

The process of building an index in this embodiment is a process of generating a tree, that is, an index of a tree structure is generated according to the directory hierarchy. of the last layer. Since the time complexity of searching the tree structure is low, the query speed is faster.

In step S103, the mobile terminal file search request information is received, and the search request information includes keyword information of the file to be searched.

In practical applications, an input box may be provided to search for corresponding files according to keywords input by the user, where the keywords are character strings related to file names.

In step S104, the keyword information is searched in the tree structure index to obtain the storage path of the file corresponding to the keyword information.

In this embodiment, after the mobile terminal receives the keyword of the file to be searched inputted by the user through the input box, it searches the file path containing the keyword in the tree structure index. Specifically: start from the current directory, search to the lowest directory of the current directory, then return to the current directory, and search from the current directory to the upper directory until the root directory, and then search from the root directory to other subdirectories in turn until A file path containing the keyword is found. Since the index is in a tree structure, the time complexity of the query is low, so compared with other query methods, it is faster and more efficient.

In step S105, the file to be searched is obtained from the storage path of the corresponding file, and the obtained file to be searched is displayed to the user.

In this embodiment, when there are multiple files to be searched, the search frequency information and classification information of each file to be searched are obtained;

calculating the weight score of each file to be searched according to the search frequency information and the classification information to which it belongs, and sorting and displaying the files to be searched according to the weight score;

Wherein, the formula for calculating the weight score of each file to be searched is:

Q=q+k _n *f _n

Q is the calculated weight score of each file to be found, q is the basic weight value corresponding to each file to be found (the basic value of each file to be found can be the same or different), n represents the nth file to be found Find the file, n is an integer greater than 0, k _n is the importance factor value set in advance according to the classification information (the importance factor value is a numerical value quantified according to the importance of the classification information, such as the value set by the picture class file The importance factor value is 1, the importance factor value set for video files is 2), and f _n is the search frequency corresponding to the nth file to be searched.

In addition, this embodiment may also display the weight score of each file to be searched in a highlighted manner, wherein the highlighted manner includes floating frame display, color-changing display, and the like.

Through the embodiment of the present invention, the mobile terminal is equipped with a file search function, which is convenient for the user to simply and quickly find the required file on the mobile terminal.
