Wherein, in the description of the present invention, unless otherwise indicated, "a plurality" means.

Currently, terminals include multiple desktops, which are commonly referred to as screens. Icons corresponding to applications downloaded and installed in the terminal are displayed on a plurality of screens, and as shown in fig. 1, a schematic diagram of a first screen, a second screen and a third screen included in the terminal is shown, wherein the first screen includes a dialing application, an information application, a browser application, an application market, a mobile phone manager, a picture and a time application, the second screen includes a communication application, a calculator, a camera, a video application, a music application, a subway application, a weather application, a shopping application and an e-mail besides the dialing application, the information application and the browser application, and the third screen includes a map application, a game application, a taxi calling application, a house application, a bank application and a voice application besides the dialing application, the information application and the browser application.

When a user needs to check a map, the terminal is opened, a displayed desktop before the last screen locking is displayed, if the displayed desktop before the last screen locking is the first screen, the user slides to the third screen, finds a map application, clicks the map application, displays the map after the map application is started, and then the user can control the map; if the displayed desktop before the last screen locking is the second screen, the user slides to the third screen, finds the map application, clicks the map application, displays the map after the map application is started, and then the user can control the map; if the displayed desktop before the last screen locking is the third screen, the user finds the map application in the third screen, clicks the map application, displays the map after the map application is started, and then the user can control the map.

In summary, the conventional map control method is complicated.

Therefore, the embodiment of the invention provides a map control method, which can solve the problem that in the prior art, a map is controlled after a map application needs to be found in a plurality of application icons in a plurality of screens, so that the map control mode is complicated.

The following is a detailed description of a map control method. As shown in fig. 2, the method specifically includes the following steps:

s200: and responding to a map display instruction input by the user through the input unit, and displaying a map corresponding to the map display instruction in the target negative screen through the display screen by the terminal.

S201: and after detecting that the user performs control operation on the map in the target negative screen, the terminal moves the map displayed in the target negative screen and/or adjusts the size of the map displayed in the target negative screen according to the control operation.

Through the scheme, when the map is controlled, the map application does not need to be searched in the plurality of screens, the map application is started to control and operate the map application, the map can be directly displayed in the target negative screen when a map display instruction is responded, a user controls and operates the map in the target negative screen, and the terminal moves the map displayed in the target negative screen and/or adjusts the size of the map displayed in the target negative screen according to the control and operation, so that the map control operation process is simplified.

For example, in the case of the terminal operating, as shown in the left diagram of fig. 3, the user inputs a map display instruction, and after the terminal responds to the map display instruction, the terminal displays the map corresponding to the map display instruction in the target negative screen. In the target negative screen, as shown in fig. 3, the map may be displayed in the form of a card, and the following target negative screens are all exemplified by negative one screen. Or the target negative screen is other negative screens besides the negative one screen, such as negative two screens, negative three screens and the like. In the negative two-screen or negative three-screen, as shown in fig. 4, the map may be displayed on the entire screen. After the map is displayed on the target negative screen, when the user performs sliding operation in the area of the map, the terminal can move the map displayed on the target negative screen along with the moving direction of the finger of the user. For example, as shown in fig. 5, the user performs a sliding operation downward or upward in the area of the map, the downward or upward sliding trajectory is a dotted-line trajectory, and the terminal follows the downward or upward movement trajectory of the user's finger to control the map to move downward or upward. Referring to fig. 6, when the user slides to the right or left in the area of the map, the track sliding to the right or left is a dotted track, and the terminal follows the movement track of the user's finger to the right or left to control the map to move to the right or left. Referring to fig. 7, when the user performs a zoom-in or zoom-out operation in the area of the map, the zoomed-in or zoom-out trajectory is a dotted-line trajectory, and the terminal adjusts the size of the map to be smaller or larger along with the movement trajectory of the user's finger for zoom-in or zoom-out.

The above-described specific implementation manner of the moving process shown in fig. 5 and 6 specifically includes:

after the terminal detects that the user performs sliding operation through the desktop application, the moving track of the touch screen touched by the user is determined, and the map displayed in the target negative screen is controlled to move through the map plug-in unit according to the moving track.

The method for detecting the sliding operation of the user by the terminal through the desktop application may include: if it is detected that the preset number of moving continuous positions of the single finger on the touch screen are in the area of the map, and the positions of the dotted line in the figure 5 and the dotted line in the figure 6 are both in the area of the map, it is determined that the user performs the sliding operation.

Optionally, the method for determining that the user performs the sliding operation may specifically be performed according to the following steps of detecting whether a first moving position of the user on the touch screen by using a single finger is in an area of the map, if so, detecting whether moving continuous positions of a target number of the user on the touch screen by using a single finger are in the area of the map, where the target number is a preset number minus 1, and if so, determining that the user performs the sliding operation. If the first mobile position of the user on the touch screen by using a single finger is detected not to be in the area of the map, the terminal judges the area corresponding to the position of the first mobile position in the target negative screen through the desktop application, if the position is not in the area of the control corresponding to the target negative screen, the operation is finished, and if the position is in the area of the control corresponding to the target negative screen, the terminal processes the control through the control in the target negative screen corresponding to the position. And if the situation that the moving continuous positions of the number of the targets on the touch screen of the user are not in the area with the uniform map is detected, determining that the user performs sliding operation on the target negative screen, and processing the sliding operation through the desktop application by the terminal.

It should be noted that the manner of determining that the user performs the sliding operation in the embodiment of the present invention is only an example, and any manner of determining that the user performs the sliding operation is applicable to the embodiment of the present invention.

After the terminal detects that the user performs sliding operation through the desktop application, the terminal sends the moving track in the sliding operation to the map plug-in through the desktop application; and the terminal controls the map displayed in the target negative screen to move according to the moving track through the map plug-in.

A flow chart of a method of moving a displayed map in a target negative screen is described below in conjunction with fig. 8:

s800: the terminal determines that the onInterceptTouchent is on the target negative screen through the desktop application, and acquires the position of the moving track.

Wherein onInterceptTouchEvent refers to handling an event that a finger touches the touch screen.

S801: and the terminal acquires the area of the map plug-in on the target negative screen by adopting plug.

S802: and if the terminal detects that the preset number of moving continuous positions of the user on the touch screen by adopting a single finger are in the area of the map through the desktop application, determining that the user performs sliding operation.

For example, when moveX > rect.x + offset is satisfied, moveX < rect.x + rect.width-offset, movy > rect.y, and movy < rect.y + rect.height, the terminal obtains the value of issrolenabledx () through reflection by the desktop application as true, that is, the preset number of mobile continuous positions are all in the map area, and the user is determined to perform the sliding operation. The issrolenabledx () function is a function of a slide operation for judging whether or not a user movement trajectory is within a map area. Wherein the issrolenabledx () function can be called by reflection in other plug-ins.

In detail, moveX > rect.x + offset means that the abscissa of the preset number of movement continuous positions corresponding to the movement of the finger is larger than the left boundary of the map, moveX < rect.x + rect.width-offset means that the abscissa of the preset number of movement continuous positions corresponding to the movement of the finger is larger than the right boundary of the map, moveY > rect.y means that the ordinate of the preset number of movement continuous positions corresponding to the movement of the finger is larger than the upper boundary of the map, and moveY < rect.y + rect.height means that the ordinate of the preset number of movement continuous positions corresponding to the movement of the finger is larger than the lower boundary of the map.

The offset mentioned above is a variable, and the offset can be customized, and is used for still realizing page turning when sliding to the left and right boundaries of the map, so as to avoid that page turning cannot be performed when the map is available. Specifically, when determining the size of moveX and the left boundary, it is possible to determine by defining offset between moveX and rect.x + offset, that is, the abscissa of the movement continuous position, and both the left boundary of the map and the display screen boundary. When judging the moveX and the right boundary, judging the moveX, and judging the width rect.x, width of map and offset.

S803: and the terminal sends the moving track in the sliding operation to the map plug-in through the desktop application.

S804: and the terminal controls the map displayed in the target negative screen to move according to the moving track through the map plug-in.

The above-described specific implementation of the map resizing shown in fig. 7 includes: and after the terminal detects that the user performs zooming operation through the desktop application, determining the position information of the touch screen touched by the user, and adjusting the size of the map displayed in the target negative screen through the map plug-in according to the position information.

The determining the zoom operation mode of the user specifically includes: if the terminal detects that the position where the user presses the touch screen by the first finger is in the area of the map through the desktop application and continues to detect that the user presses the touch screen by the second finger before the user lifts the first finger, determining that the user performs zooming operation; or

And if the terminal detects that the positions where the user presses the touch screen by two fingers simultaneously are both in the area of the map through the desktop application, determining that the user performs zooming operation.

It should be noted that the manner of determining the zoom operation performed by the user in the embodiment of the present invention is only an example, and any manner of determining the zoom operation performed by the user is applicable to the embodiment of the present invention.

After the terminal detects that the user performs zooming operation through the desktop application, the terminal sends the position information in the zooming operation to the map plug-in through the desktop application; and the terminal adjusts the size of the map displayed in the target negative screen according to the position information through the map plug-in.

A flow chart of a method of resizing a displayed map in a target negative screen is described below in conjunction with fig. 9:

s900: the terminal determines that the onInterceptTouchent is on the target negative screen through the desktop application, and acquires the position information of the finger in the target negative screen.

S901: the terminal detects whether the positions of two fingers of a user pressing the touch screen within a preset time period are both in the area of the map view through the desktop application; if yes, S902 is executed, and if no, the process ends.

S902: and determining that the user performs zooming operation, and sending the position information in the zooming operation to the map plug-in by the terminal through the desktop application.

S903: and the terminal adjusts the size of the map displayed in the target negative screen according to the position information through the map plug-in.

The method for displaying the map, which is input by the user through the input unit, may include:

the first condition is as follows: and generating a map display instruction when the operation that the user slides to the target negative screen is detected.

Referring to fig. 3, when the terminal is running, the user may slide from the third screen to the negative one screen, and after the target negative screen is slid, the terminal displays the map on the negative one screen through the desktop application.

Case two: and generating a map display instruction according to the information input by the user through the input unit.

As shown in fig. 10, a user may input a "map" word in a search bar of a desktop in the terminal, and after the terminal receives the "map" word, the terminal turns from a current screen to a target negative screen through a desktop application, and displays a map corresponding to a map display instruction on the target negative screen. Or, with reference to fig. 11, the user may input a "map" word in a search bar of a voice application in the terminal, and after the terminal receives the "map" word, the terminal switches from the voice application to a target negative screen, and displays a map corresponding to the map display instruction on the target negative screen.

It should be noted that the manner of generating the map display instruction recited in the embodiment of the present invention is only an example, and any manner of generating the map display instruction is applicable to the embodiment of the present invention.

In the practical application process, a user may need to check a map of a location of the user and may also need to check a map of a location other than the user, so that the way in which the user checks the map is more efficient, the embodiment of the present invention may determine whether the map that the user wants to check can be analyzed in the map display instruction to determine which location of the map is displayed. Specifically, the method comprises the following steps:

the first condition is as follows: if the place can be analyzed through the map display instruction, the map corresponding to the map display instruction is a map of a preset range with the place as the center.

It can be understood that: the place can be analyzed through the map display instruction, namely when the map display instruction comprises the place which the user wants to view, the map with the place as the center and the preset range is obtained. For example, as shown in fig. 10, in a search bar of a desktop in the terminal, a word "a-zone map" is input, the terminal receives and analyzes the word "a-zone map", it can be seen that the map display instruction includes a location "a-zone", and a map of a preset range with the a-zone as a center of the terminal is displayed on the target negative screen. Alternatively, as shown in fig. 11, in the voice application, the user inputs "a-zone map", the terminal receives and parses the word "a-zone map", the terminal changes from the display interface of the voice application to the target negative screen, and the map of the preset range with the a-zone as the center is displayed in the target negative screen.

Case two: if the place cannot be analyzed through the map display instruction, the map corresponding to the map display instruction is a map in a preset range with the place where the user is located as the center.

It can be understood that: the location cannot be analyzed through the map display instruction, namely the map display instruction does not include the location which the user wants to view, and the map with the location of the user as the center is within the preset range. For example, as shown in fig. 10, in a search bar of a desktop in the terminal, a "map" character is input, and the terminal receives and analyzes the "map" character, and it can be seen that a map display instruction does not include a place, and a map of a preset range centered on a user is displayed on the target negative screen by the terminal. Alternatively, as shown in fig. 11, in the voice application, the user inputs a "map", the terminal receives and parses the "map" word, the terminal changes from the display interface of the voice application to the target negative screen, and the map of the preset range centered on the user is displayed in the target negative screen.

In summary, the embodiment of the invention can determine the map display range directly by analyzing the map display instruction, and does not need the user to search the map for the location to be checked, thereby improving the map searching efficiency.

In the existing negative screen, there is no function of displaying a map, so the invention can add a map display function in the target negative screen, and then the map can be displayed in the target negative screen when responding to a map display instruction, wherein, with reference to fig. 12, the specific process of adding the map display function and the map display in the target negative screen includes:

s1200: the terminal obtains the context information of the map plug-in through the desktop application.

In detail, the package name of the map plug-in is set as mPackageName, and the obtaining of the context information of the map plug-in may be:

Context mRemoteContext＝Utilities.getTargetContext(context,pkg),Context.CONTEXT_INCLUDE_CODE

|Context.CONTEXT_IGNORE_SECURITY)。

s1201: and the terminal acquires the map layout file by using a reflection mechanism according to the context information of the map plug-in through the desktop application.

The map layout file of the map plug-in is obtained, and the map layout file can be understood as a map layout file class defined by the desktop application. The detailed process is that the map plug-in adds a map identifier to the map layout file, and the desktop application obtains the map layout file of the map plug-in through the map identifier, namely:

Resources targetResource＝mRemoteContext.getResources()；
