Detailed Description
The invention will now be described in more detail with reference to the accompanying drawings, to which it should be noted that the description is given below by way of illustration only and not by way of limitation. Various embodiments may be combined with one another to form further embodiments not shown in the following description.
Example 1
An embodiment provides a TextView linear scaling method, which aims to avoid the problem that line feed points are inconsistent and notes cannot be aligned due to the fact that input characters are limited to avoid non-linearity during linear scaling.
TextView refers to a text view in an android (android) system, and text presentation in APP in the android system is usually required to be realized through TextView.
Referring to FIG. 1, a text view linear scaling method includes the following steps:
s110, receiving input characters according to a preset textSize character type;
in some versions of android systems, the character types are forced to be rounded, so that the problem of nonlinear scaling of some floating-point input characters occurs, and therefore in this embodiment, the preset character types are uniformly set to integer, i.e. the configured TextSize is integer.
The purpose of presetting the character types in S110 is to unify the text sizes, so as to avoid the problem that the text with different character types is nonlinear due to different sizes when scaled linearly.
S120, configuring a linear mark at a marker position of a painting brush of the input character; the method comprises the steps of carrying out a first treatment on the surface of the
The brush mark in S120 refers to a brush function in TextView, such as text thickening, underline adding, antialiasing mark adding, etc., and since the system rounds the character width when the brush mark bit does not contain the linear mark, thereby causing nonlinearity of the brush mark, in S120, the linear mark is added to all the brush marks, so as to avoid the problem that the brush mark and the input character are not matched after linear scaling.
The linear flags described above are those configured by setpaintfligs.
S130, matching fonts for the input characters according to a preset font library, wherein the preset font library is a font library covering all display character sets;
the android system combines textSize and character width height in a used font library when calculating font width height, if characters in the font library do not contain characters to be displayed currently, the system can use default characters, and the problem that linear scaling cannot be achieved due to different default character widths of different systems is solved. Therefore, in this embodiment, the matching of fonts is completed by calling the font library preset by the "setTypeface" command, and the preset font library is the font library covering all the display character sets, and since the fonts of the display character sets of different APP (application program) are different, different preset font libraries may be set according to different APP, or may be a font library containing all the fonts, which is not limited in this embodiment.
Through the font library of the standard text, the linear control of the character width and height can be realized.
S140, calculating the width and height of the input character according to the TextView width and the font characteristics of the character;
in some versions of android systems, the font width cannot be linearly scaled due to the fact that the font width is adjusted for specific adjacent characters in the font library, and the system performs a character distance adjustment (character even distance) process of the adjacent characters on the calculated character width, which causes nonlinearity in part of the scene; preferably, to avoid this problem, this is achieved by turning off the pitch adjustment function, i.e. the kerning function.
Specifically, referring to fig. 2, the method includes the following steps:
s1401, calling the font characteristics of the input characters, and closing a character pitch adjusting function;
s1402, calculating the width and height of the character according to the character font characteristics.
The android system automatically calculates the width and height of the characters according to the character types and fonts to adapt to the width of TextView, and the calculation method is a general calculation method, so this embodiment will not be described in detail.
And S150, linearly scaling the width of the TextView control and the input characters according to different android devices.
After the steps are completed, the TextView can be linearly widened on different Android devices.
Example two
The second embodiment is based on the first embodiment, and mainly describes a process of scaling the whole width and the text size of the TextView control according to linear scaling on different devices.
Specifically, referring to fig. 3, the text view control width and the input character are scaled linearly according to different android devices, and the method includes the following steps:
s210, reading the TextView width and the height of the input character, wherein the TextView width and the height of the input character are even numbers;
s220, calculating pixel proportions of the current equipment and the reference equipment, and downwards taking the pixel proportions to be an integral multiple of 0.5 to obtain a scaling factor;
it should be noted that, in S210, the TextView width and the width and height of the input character are defined as even numbers, because the width of the control in the android system is integer, when the accuracy needs to be strictly controlled, the width and the text size need to be set as even numbers, because the linear ratio is an integer multiple of 0.5 and an integer multiple of 0.5 is a general linear ratio of the android system in S220, the even numbers can avoid the width of the control after scaling to be decimal.
In the embodiment, the reference device in S220 selects a device with a display area of 1024×768, and calculates the pixel ratio of the current device and the reference device in the text layout direction when calculating the pixel ratio.
And S230, linearly scaling the TextView control and the input character according to the scaling coefficient.
