Based on the above-mentioned hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are presented.
Referring to fig. 3, fig. 3 is a flowchart illustrating steps of a hiding method according to an embodiment of the present invention, where the method is applied to a mobile terminal, as shown in fig. 3, and the method includes:
In this embodiment, when the user requests to access the upper directory of the target object, the mobile terminal receives an access request to the upper directory of the target object. The target object includes one or more of a file, a folder, and an application icon.
It will be appreciated that when the target object includes a file and/or a folder, the upper directory of the target object includes the folder in which the target object is located, and the access request to the target object includes an access request to the folder in which the target object is located. When the target object includes an application icon, the upper directory of the target object includes a desktop page where the application icon is located, and correspondingly, the access request to the target object includes a display request for the desktop page where the target object is located (for example, a request for switching the mobile terminal from another desktop page to the desktop page where the target object is located).
When the target object includes a file and/or a folder, the access request to the upper directory of the upper level target of the target object may include an opening operation to the folder where the target object is located, or may include a call request from another application to the folder where the target object is located. For the case that the access request includes the opening operation performed by the folder where the target object is located, mediaProvider is added to the frame of the disk, specifically, the MediaProvider may be added to a listFile file in the file.
It may be understood that when the mobile terminal receives an access request of a superior directory of a target object, the mobile terminal needs to display all objects (including the target object) under the superior directory of the target object.
And step 302, responding to the access request, and inquiring whether a record corresponding to the target object exists in a MediaProvider (media provider) file of the mobile terminal.
In the step, the mobile terminal responds to the access request and inquires whether a record corresponding to the target object exists in a MediaProvider file of the mobile terminal. It can be understood that, if the target object needs to be hidden, the mobile terminal deletes the record corresponding to the target object in the MediaProvider file after receiving the hiding operation on the target object. In this embodiment, the mobile terminal determines whether the target object needs to be hidden by querying whether a record corresponding to the target object exists in the MediaProvider file.
For the case that the access request includes an opening operation performed on a folder where the target object is located, the mobile terminal may obtain the MediaProvider from listFile in a file.java file of a Framework of a disk, and query whether a record corresponding to the target object exists in the MediaProvider file.
In this step, if there is no record corresponding to the target object in the MediaProvider file, the target object is hidden. It can be understood that, for the mobile terminal, when the target object needs to be displayed, the record corresponding to the target object in the MediaProvider file needs to be acquired, and in this step, if the record corresponding to the target object is not available in the MediaProvider file, the mobile terminal cannot acquire the record corresponding to the target object, and therefore, the target object cannot be displayed, and the hiding of the target object can be achieved.
In this embodiment, the hiding method receives an access request to an upper directory of a target object; responding to the access request, and inquiring whether a record corresponding to the target object exists in a media provider file of the mobile terminal; and if no record corresponding to the target object exists in the MediaProvider file, hiding the target object. According to the hiding method provided by the embodiment, whether the target object is hidden is determined according to whether the record corresponding to the target object exists in the MediaProvider file, if the record corresponding to the target object does not exist, the target object is not displayed, the target object is not required to be moved to a folder with special authority, the hiding can be achieved, and the hiding efficiency can be effectively improved.
Optionally, the receiving an access request to the upper directory of the target object includes:
receiving an access request to a folder where a target object is located;
or receiving a display request of the desktop page where the target object is located.
In this embodiment, the target object may be a file or a folder, or may be an application icon. When the target object is a file or a folder, the upper-level directory of the target object is the folder where the target object is located, and correspondingly, receiving the access request to the upper-level directory of the target object includes receiving the access request to the folder where the target object is located. When the target object is an application icon, the upper-level directory of the target object is a desktop page where the target object is located, and correspondingly, receiving the access request to the upper-level directory of the target object includes receiving a display request to the desktop page where the target object is located.
Optionally, the target object includes one or more of a file, a folder, and an application icon.
In this embodiment, the target object may include a file, a folder, and an application icon, which is not specifically limited in the embodiment of the present invention.
Referring to fig. 4, fig. 4 is a second flowchart of a hiding method according to an embodiment of the present invention, where the hiding method is applied to a mobile terminal, as shown in fig. 4, and the method includes:
In the step, the mobile terminal determines a target object on the mobile terminal according to the Fileobserver, wherein the target object is an object to be hidden on the mobile terminal. The mobile terminal determines whether the object is a target object according to the hidden field corresponding to each object in the Fileobserver, and specifically, the mobile terminal can acquire the hidden field corresponding to each object in the Fileobserver; judging whether the hidden field corresponding to each object is in a valid state or not; and determining the object with the hidden field in the valid state as a target object.
And step 402, deleting the record corresponding to the target object in the MediaProvider file.
After determining the target object to be hidden on the mobile terminal, in the step, the mobile terminal deletes the record corresponding to the target object in the MediaProvider file.
And step 404, responding to the access request, and inquiring whether a record corresponding to the target object exists in the media provider file of the mobile terminal.
The steps 403 to 405 are the same as the steps 301 to 303 in the embodiment of fig. 3, and are not repeated here.
In this embodiment, the hiding method determines a target object in the mobile terminal according to a file listener of the mobile terminal, where the target object is an object to be hidden on the mobile terminal; deleting a record corresponding to the target object in the MediaProvider file; receiving an access request to a superior directory of a target object; responding to the access request, and inquiring whether a record corresponding to the target object exists in a media provider file of the mobile terminal; and if no record corresponding to the target object exists in the MediaProvider file, hiding the target object. According to the hiding method provided by the embodiment, whether the target object is hidden is determined according to whether the record corresponding to the target object exists in the MediaProvider file, if the record corresponding to the target object does not exist, the target object is not displayed, the target object is not required to be moved to a folder with special authority, the hiding can be achieved, and the hiding efficiency can be effectively improved.
Referring to fig. 5, fig. 5 is a third flowchart of a hiding method according to an embodiment of the present invention, where the hiding method is applied to a mobile terminal, as shown in fig. 5, and the method includes:
In this step, the mobile terminal obtains the hidden field corresponding to each object in the Fileobserver.
In this step, the mobile terminal determines whether the hidden field corresponding to each object is in a valid state. In the embodiment of the invention, after receiving the hiding operation executed on the target object, the mobile terminal sets the hiding object corresponding to the target object to be in an effective state. In this embodiment, the mobile terminal determines the target object by determining whether the hidden field corresponding to the object in the Fileobserver is in a valid state.
And 503, determining the object with the hidden field in the valid state as a target object, wherein the target object is the object to be hidden on the mobile terminal.
In this step, the mobile terminal determines the object whose hidden field is in the valid state as the target object. The hidden field corresponding to the object may be a hidden flag bit corresponding to the object, and different characters may indicate that the object is in different states. For example, the character "1" may be defined to indicate that the hidden field is in a valid state, and the character "0" may be defined to indicate that the hidden field is in an invalid state. Correspondingly, when the hidden field corresponding to the object A is the character '1', the mobile terminal determines that the hidden field corresponding to the object A is in a valid state; conversely, when the hidden field corresponding to the object a is the character "0", the mobile terminal determines that the hidden field corresponding to the object a is in an invalid state.
For example, assuming that the hidden fields respectively corresponding to the objects B, C, D are all valid, the mobile terminal determines the object B, C, D as the target object.
And step 504, deleting the record corresponding to the target object in the MediaProvider file.
And step 506, responding to the access request, and inquiring whether a record corresponding to the target object exists in the media provider file of the mobile terminal.
The steps 504 to 507 are the same as the steps 402 to 405 in the embodiment of fig. 4, and are not repeated here.
In this embodiment, the hiding method obtains a hidden field corresponding to each object in the Fileobserver; judging whether the hidden field corresponding to each object is in a valid state or not; determining an object with the hidden field in an effective state as a target object, wherein the target object is an object to be hidden on the mobile terminal; deleting a record corresponding to the target object in the MediaProvider file; receiving an access request to a superior directory of a target object; responding to the access request, and inquiring whether a record corresponding to the target object exists in a media provider file of the mobile terminal; and if no record corresponding to the target object exists in the MediaProvider file, hiding the target object. According to the hiding method provided by the embodiment, whether the target object is hidden is determined according to whether the record corresponding to the target object exists in the MediaProvider file, if the record corresponding to the target object does not exist, the target object is not displayed, the target object is not required to be moved to a folder with special authority, the hiding can be achieved, and the hiding efficiency can be effectively improved.
Optionally, before the determining, according to the Fileobserver of the mobile terminal, the target object in the mobile terminal, the method further includes:

and responding to the hiding operation, and setting a hidden field corresponding to the target object in the Fileobserver to be in a valid state.
In this embodiment, when receiving a hiding operation performed on a target object, the mobile terminal responds to the hiding operation to set a hiding field corresponding to the target object in the Fileobserver to a valid state. Specifically, the setting the hidden field corresponding to the target object in the Fileobserver to the valid state may include: and setting a hidden field corresponding to the target object in the Fileobserver to be 1.
Optionally, if the MediaProvider file does not have a record corresponding to the target object, after hiding the target object, the method further includes:
receiving a unhiding operation performed on the mobile terminal;
and responding to the hiding canceling operation, and setting a hidden field corresponding to the target object in the Fileobserver to be in an invalid state.
