The present disclosure generally relates to the technical field of display of user interface and, more particularly, to a method and a device for adjusting characters of an application.
With the development of software technology, more and more applications are developed and applied on cell phones, which facilitates and enriches people's lives. However, applications may be limited by the screen size of a cell phone. The more contents to be presented, the smaller a displayed font size will be. Generally, a default word size of an application set on a cell phone can meet most people's requirements. Certain smart cell phones also provide the function of changing the font size of applications to accommodate different users. For example, a cell phone can provide a magnifying setting for the font size to allow users with poor vision to magnify characters of applications.
A conventional method for changing the font size of an application includes the cell phone providing a setting item for a user to select a proportion for scaling up or scaling down characters, such as a 120% magnification or a 150% magnification. The cell phone then scales up or scales down all characters of the application once according to the selected proportion for display, for example, magnifying all characters of the application once to 120% of the original font size. As a result, certain characters may be cropped out of the screen of the cell phone.

It is to be understood that both the foregoing general description and the following, detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.
a and 3b are schematic diagrams of a display of applications on a desktop in different font modes, according to exemplary embodiments.
a, 4b and 4c are schematic diagrams of a display of an address book application in different font modes, according to exemplary embodiments.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of devices and methods consistent with aspects related to the invention as recited in the appended claims.
In step 101, the device receives an instruction for adjusting the application characters according to a first scaling coefficient.
For example, the device can receive the instruction for adjusting the application characters according to the first scaling coefficient through a set human-machine interaction interface. The human-machine interaction interface may be a selection menu of scaling coefficients including the first scaling coefficient, a selection icon corresponding to the first scaling coefficient, or a selection key of scaling coefficients.
In one exemplary embodiment, the selection menu of scaling coefficients is provided to a user in a system menu, and the selection menu displays tags of the scaling coefficients, respectively. Accordingly, the user can access the selection menu of scaling coefficients level by level through the system menu to select the first scaling coefficient for adjustment.
In one exemplary embodiment selection icons of respective scaling coefficients are provided to the user on a display interface of the application, and different selection icons correspond to different scaling coefficients. Accordingly, the user can select a scaling coefficient for adjustment by clicking the corresponding selection icon.
In one exemplary embodiment, the selection key of scaling coefficients is provided to the user. Accordingly, the user can select the first scaling coefficient for adjustment by clicking the selection key.
In step 102, the device determines whether there is a second scaling coefficient for the application that is based on the first scaling coefficient.
In one exemplary embodiment, the device obtains descriptive information in a scaling permission description field of the application, and the scaling permission description field is configured to indicate whether there is a second scaling coefficient for the application that is based on the first scaling coefficient. For example, if the device uses an Android operating system, the scaling permission description field may be in an Androidmanifest.xml file. If descriptive information in the Androidmanifest.xml file is true, the device determines that there is a second scaling coefficient for the application that is based on the first scaling coefficient.
The device performs step 103 if it is determined that there is no second scaling coefficient for the application that is based on the first scaling coefficient (102—No). Otherwise (102—Yes), the device performs step 104.
In step 103, the application characters are adjusted according to the first scaling coefficient.
In one exemplary embodiment, consistent with step 103, a font size and a layout of the application characters are adjusted according to the first scaling coefficient. For example, a character library of the application corresponding to the first scaling coefficient is obtained through check ng a stored correspondence between the first scaling coefficient and the character library, and the application characters are adjusted to the obtained character library corresponding to the first scaling coefficient.
In one exemplary embodiment, prior to adjusting the application characters according to the first scaling coefficient, the method 100 may also include determining whether a font size of the application characters after the adjustment will reach a predetermined threshold. If it is determined that the font size of the application's characters will not reach the predetermined threshold, the application characters are adjusted according to the first scaling coefficient. If it is determined that the font size of the application characters will reach the predetermined threshold, the application characters are adjusted to system default characters.
In the illustrated embodiment, the adjustment process is intelligently controlled to adjust the application characters according to the first scaling coefficient, that is, if the font size of the application characters after the adjustment will reach the predetermined threshold, the adjustment is not implemented and the application characters are adjusted to the system default characters, so as to ensure the display effect of the application characters after scaling, and to avoid blurring of the application characters due to over scaling.
In step 104, the application characters are adjusted according to the second scaling coefficient.
In one exemplary embodiment, consistent with step 104, the font size and the layout of the application characters are adjusted according to the second scaling coefficient. For example, a character library of the application corresponding to the second scaling coefficient is obtained through checking a stored correspondence between the second scaling coefficient and the character library, and the application characters are adjusted to the obtained character library corresponding to the second scaling coefficient.
In one exemplary embodiment, prior to adjusting the application characters according to the second scaling coefficient, the method 100 may further include determining whether the font size of the application characters after the adjustment will reach the predetermined threshold. If it is determined that the font size of the application characters will not reach the predetermined threshold, the application characters are adjusted according to the second scaling coefficient. If it is determined that the font size of the application characters will reach the predetermined threshold, the application characters are adjusted according to the first scaling coefficient.
In the above embodiment, the adjustment process is intelligently controlled to adjust the application characters according to the second scaling coefficient, that is, if the font size of the application characters after the adjustment will reach the predetermined threshold, the application's characters are adjusted according to the first scaling coefficient, to ensure the display effect of the application characters after scaling, and to avoid blurring of the application characters due to over scaling.
In the illustrated embodiment, the second scaling coefficient is set according to the first scaling coefficient, such that the application characters may be further adjusted according to the second scaling coefficient after the application characters are adjusted according to the first scaling coefficient. For example, during a process of magnifying the font size of the application characters, the first scaling coefficient is set to 1.1 (that is, the application characters are magnified by a factor of 1.1 on the basis of a system default font size), then the second scaling coefficient may be set to 1.2 (that is, the application characters may be magnified by a factor of 1.2 on the basis of the system default font size), such that after the application characters are adjusted according to the first scaling coefficient, the application may be further magnified according to the second scaling coefficient if allowed.
In the illustrated embodiment, when the device receives the instruction for adjusting the application characters according to the first scaling coefficient and determines that there is a second scaling coefficient for the application that is based on the first scaling coefficient, the device can adjust the application characters according to the second scaling coefficient. If it is determined that there is no second scaling coefficient for the application that is based on the first scaling coefficient, the device can adjust the application characters according to the first scaling coefficient. The application characters are flexibly adjusted, so as to allow the application characters to fit the application's display interface and to prevent the characters from being cropped or forced out of a screen of the device after the adjustment.
In one exemplary embodiment, a plurality of character system modes are set in advance, and each of the character system modes corresponds to a plurality of scaling coefficients in which a next scaling coefficient, e.g., the second scaling coefficient described above, is set according to a previous scaling coefficient, e.g., the first scaling coefficient described above. Table 1 below shows a correspondence between the character system modes and the scaling coefficients.
In the illustrated embodiment, the first scaling coefficient is a system default scaling coefficient. The first scaling coefficient may be obtained by statistics according to a proportion of the display interface occupied by the application characters at different values of the font size. The first scaling coefficient is considered a safe scaling coefficient under which the application characters will not be cropped or forced out of the screen. The second scaling coefficient is a selectable coefficient which is indicated in, e.g., the Androidmanifest.xml file of the application and can be set by the application's developers according to the application's own layout. Generally, the set second scaling coefficient may be used to further scale the application characters and to further ensure that the adjusted application characters will not be cropped or forced out of the screen.
Additionally, in the illustrated embodiment, the scaling threshold is also provided. If the application characters after the adjustment will reach the scaling threshold, the application characters will not be adjusted according to any scaling coefficient. The application characters are adjusted according to a determined scaling coefficient, such as the first scaling coefficient or the second scaling coefficient, only when the application characters after the adjustment will not reach the scaling threshold, so as to ensure the display effect of the application characters after scaling and to avoid blurring of the application characters due to over scaling.
In step 201, the device receives an instruction for adjusting the application characters according to a first scaling coefficient.
In one exemplary embodiment, the user accesses a character system mode menu level by level through a main menu. The character system mode menu provides respective options for character system modes, such as a small font mode, a standard font mode, an intermediate font mode, a large font mode and an ultra-large font mode. The user can select a character system mode, such as the large font mode. The device enters into the large font mode, and checks a correspondence between the selected character system mode and a first scaling coefficient to obtain the first scaling coefficient corresponding to the selected character system mode, e.g., obtain a first scaling coefficient 13 corresponding to the selected large font mode. The instruction for adjusting the application characters according to the first scaling coefficient is sent to a processor of the device. The processor receives the instruction for adjusting the application characters according to the first scaling coefficient.
In step 202, the device determines whether there is a second scaling coefficient for the application that is based on the first scaling coefficient.
The device performs step 203 if it is determined that there is no second scaling coefficient for the application that is based on the first scaling coefficient (202—No). Otherwise (202—Yes), the device performs step 206.
In one exemplary embodiment, in performing step 202, the device uses the Android operating system, and descriptive information in an Androidmanifest.xml file of the application is obtained. The device determines that the application characters may be further scaled if a value of the descriptive information of the Androidmanifest.xml file is, e.g., 1, and then checks a correspondence between the selected character system mode and a second scaling coefficient to obtain the second scaling coefficient, e.g., 1.4, for the selected large font mode. If the value of the descriptive information of the Androidmanifest.xml file is, e.g., 0, the device determines that the application characters are not allowed to be further scaled. Accordingly, the device determines that there is no second scaling coefficient for the application.
In step 203, it is determined whether a font size of the application characters after the adjustment according to the first scaling coefficient will reach the predetermined threshold.
If it is determined that the font size of the application characters after the adjustment will not reach the predetermined threshold (203—No), in step 204, the application characters are adjusted according to the first scaling coefficient and operations end.
In one exemplary embodiment, the font size and the layout of the application characters are adjusted according to the first scaling coefficient. For example, the correspondence between stored scaling coefficients and the application's character libraries is searched to obtain a character library corresponding to the first scaling coefficient, e.g., a character library corresponding to 1.3 times the system default characters, and the application characters are adjusted to the font size and the layout corresponding to 1.3 times the system default characters.
If it is determined that the font size of the application's characters after the adjustment will reach the predetermined threshold (203—Yes), in step 205, the application characters are adjusted to the system default characters and operations end.
In the illustrated embodiment, prior to adjusting the application characters according to the first scaling coefficient, the adjustment process is intelligently controlled, that is, if the font size of the application characters after adjustment will reach the predetermined threshold, the adjustment is not implemented and the application characters are adjusted to the system default characters, to ensure the display effect of the application characters after scaling, and avoid blurring of the application's characters due to over scaling.
In step 206, if it is determined that there is a second scaling coefficient for the application that is based on the first scaling coefficient (202—Yes), it is further determined whether the font size of the application characters after the adjustment according to the second scaling coefficient will reach the predetermined threshold.
If it is determined that the font size of the application characters after the adjustment will not reach the predetermined threshold (206—No), in step 207, the application characters are adjusted according to the second scaling coefficient and operations end.
In one exemplary embodiment, consistent with step 207, the font size and the layout of the application's characters are adjusted according to the second scaling coefficient. For example, a character library corresponding to the second scaling coefficient is obtained through checking the correspondence between scaling coefficients and character libraries. For example, the character library corresponding to 1.4 times the system default characters is obtained, and the application's characters are adjusted to the font size and the layout corresponding to 1.4 times the system default characters.
If it is determined that the font size of the application characters after the adjustment will reach the predetermined threshold (206—Yes), in step 208, the application characters are adjusted according to the first scaling coefficient and operations end.
In one exemplary embodiment, consistent with step 208, prior to adjusting the application characters according to the first scaling coefficient in step 208, steps 203 to 205 are also performed to ensure the font size of the application characters will not exceed the predetermined threshold after the application characters are adjusted according to the first scaling coefficient.
In the illustrated embodiment, prior to adjusting the application characters according to the second scaling coefficient, the adjustment process is intelligently controlled, that is, if the font size of the application characters will reach the predetermined threshold, the application characters are adjusted according to the first scaling coefficient, to ensure the display effect of the application characters after scaling, and to avoid blurring of the application characters due to over scaling.
In one exemplary embodiment, the device is a cell phone, and the user wants to adjust characters of applications displayed on a desktop. For example, the user selects to adjust the applications characters to the large font mode through the selection menu. The cell phone checks a first scaling coefficient corresponding to the large font mode, such as 1.3, after receiving an instruction for adjusting the applications characters to the large font mode. Thereafter, the applications characters are magnified according to the first scaling coefficient, which may include magnifying the font size and the layout (including an icon size) of the applications.
In one exemplary embodiment, the user wants to adjust characters of an address book installed on the cell phone. For example, the user selects to adjust the address book's characters to the large font mode through the selection menu. The cell phone obtains a first scaling coefficient corresponding to the large font mode, such as 1.3, after receiving an instruction for adjusting the address book's characters to the large font mode. Thereafter, the address book's characters are magnified according to the first scaling coefficient, which may include magnifying the font size, the content, the layout, the picture size, and the interaction function display of the address book.
In the illustrated embodiment, a second magnification may be performed on the characters in the address book shown in
In the illustrated embodiment, when the cell phone receives the instruction for adjusting the application characters according to the first scaling coefficient, and determines that there is a second scaling coefficient for the application that is based on the first scaling coefficient, the cell phone adjusts the application characters according to the second scaling coefficient. If it is determined that there is no second scaling coefficient for the application, the cell phone adjusts the application characters according to the first scaling coefficient. The application characters are flexibly adjusted to allow the application characters to fit the application's display interface and to prevent the characters from being cropped or forced out of the screen of the cell phone after the adjustment.
In one exemplary embodiment, the receiving module 501 is configured to receive the instruction for adjusting the application characters according to the first scaling coefficient via a set human-machine interaction interface, and the human-machine interaction interface is one of a selection menu of scaling coefficients, a selection icon of the first scaling coefficient, or a selection key of scaling coefficients.
