All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
When the View interface implements the selection of a line segment, it is generally necessary to calculate the hot zone range of the line segment. And judging whether the current line segment is selected or not by calculating whether the click point is in the hot zone range or not. In determining the line segment hot zone range in the prior art, the following method is generally adopted for determination: the Path class method provided by Android (Android) system API (Application Programming Interface) returns to the hot zone range. However, the hot zone range is a rectangular range drawn with the start point to the end point of the line segment as a diagonal line, and as shown in fig. 1A, a rectangular dotted line box indicates the hot zone ranges corresponding to the line segments ab, bc, and cd. The range of the hot zone of the angular line segment determined in the method can become large, so that experience problems such as overlapping of the hot zones can occur. The determined hot zone range of the horizontal and vertical line segments is in the same direction because the starting point and the ending point can lead the hot zone range to become a straight line, so that the hot zone range is too small, and experience problems such as difficulty in selection and the like exist.
Example 1
Fig. 1B is a flowchart of a method for determining a range of a thermal zone according to an embodiment of the present invention, where the method may be performed by a device for determining a range of a thermal zone of a line segment, and the device for determining a range of a thermal zone may be implemented in hardware and/or software, and the device for determining a range of a thermal zone may be configured in an electronic device. As shown in fig. 1A, the method includes:
s110, when a target line segment drawn in the canvas interface is detected, acquiring a first start point coordinate and a first end point coordinate of the target line segment.
The canvas interface may be a View interface in the process of Android custom interface development. The target line segment may be a line segment drawn by the relevant person in the View interface.
Illustratively, when it is detected that a target line segment is drawn in the View interface, a first start point coordinate and a first end point coordinate of the target line segment are obtained. The first endpoint coordinate may be a position coordinate when the coordinate of the initial clicking point is dragged to stop at the endpoint position. A line segment with a specific length and angle is formed by the first start point coordinate and the first end point coordinate.
S120, determining a horizontal hot zone range corresponding to the target line segment according to the first starting point coordinate and the first end point coordinate.
The horizontal hot zone range may be a hot zone range of a horizontal line segment in a horizontal direction corresponding to the target line segment.
In an alternative embodiment, determining the horizontal hot zone range corresponding to the target line segment according to the first start point coordinate and the first end point coordinate includes: determining a horizontal line segment of the target line segment in the horizontal direction according to the first starting point coordinate and the first ending point coordinate; and determining the horizontal hot zone range of the horizontal line segment according to the coordinate points on the horizontal line segment.
The determining manner of the horizontal line segment of the target line segment in the horizontal direction may be that the line segment length of the target line segment is determined according to the first start point coordinate and the first end point coordinate. In particular, the determination may be made by means of a trigonometric function. And constructing a horizontal line segment with the length being the length of the line segment of the target line segment in the horizontal direction by taking the first starting point coordinate of the target line segment as a starting point. For example, if the first origin coordinate of the target line segment is (x 1 ，y 1 ) If the length of the target line segment is m, the starting point coordinates of the horizontal line segment are (x) 1 ，y 1 ) The end point coordinates of the horizontal line segment are (x) 1 +m，y 1 )。
According to coordinate points on the horizontal line segment, determining the horizontal hot zone range of the horizontal line segment, for example, a margin value can be preset, so that the horizontal line segment determines the horizontal hot zone range of the rectangular area based on the preset margin value, wherein the margin value from each coordinate point in the horizontal line segment to each side of the rectangular area closest to the coordinate point is the same. It is understood that the preset margin value may be preset by a related technician according to the requirement.
In an alternative embodiment, the coordinate points on the horizontal line segment include a second start point coordinate and a second end point coordinate; correspondingly, determining the horizontal hot zone range of the horizontal line segment according to the coordinate point on the horizontal line segment comprises the following steps: determining the width of the hot zone according to the second starting point coordinates, the second ending point coordinates and a preset width margin threshold; according to the second starting point coordinates and/or the second ending point coordinates, combining a preset height margin threshold value, and determining the height of the hot zone; and constructing a horizontal hot zone range of the horizontal line segment according to the hot zone width and the hot zone height.
The preset width margin threshold may include a preset left margin threshold and a preset right margin threshold. The preset height margin threshold may include a preset upper margin threshold and a preset lower margin threshold. The preset width threshold and the preset height threshold may be preset by a related technician. Specifically, the preset width threshold value and the preset height threshold value may be set to the same value, or may be set to different values.
Illustratively, the width of the horizontal line segment to the left boundary of the horizontal hot zone range may be determined according to the second starting point coordinates and a preset left margin threshold; according to the second end point coordinates and a preset right margin threshold value, the width from the horizontal line segment to the right boundary of the horizontal hot zone range can be determined; according to the second starting point coordinates or the second ending point coordinates, the width from the horizontal line segment to the upper boundary of the horizontal hot area range can be determined by combining a preset upper margin threshold; and according to the second starting point coordinates or the second ending point coordinates, combining a preset lower margin threshold value, and determining the width from the horizontal line segment to the lower boundary of the horizontal hot zone range.
The width of the hot zone can be the sum of a preset left margin threshold value, the length of a horizontal line segment and a preset right margin threshold value; the hot zone height may be the sum of a preset upper margin threshold, a horizontal line segment width, and a preset lower margin threshold. The width of the horizontal line segment is the same as the thickness of the target line segment, and is specifically determined by a relevant technician when drawing the target line segment. For example, the horizontal line segment width may be 1 pound (pt).
A schematic of the horizontal hot zone extent of a horizontal line segment is shown in fig. 1C. The line segment a may represent a preset left margin threshold, the line segment B may represent a preset right margin threshold, the line segment C may represent a preset upper margin threshold, and the line segment D may represent a preset lower margin threshold. According to the preset left margin threshold value, the preset right margin threshold value, the preset upper margin threshold value and the preset lower margin threshold value, the horizontal hot zone range of the horizontal line segment can be determined based on the first starting point coordinate and the second ending point coordinate.
S130, determining the target hot zone range of the target line segment according to the horizontal hot zone range.
For example, the horizontal hot zone range may be taken as the target hot zone range of the target line segment. When the target hot zone range is the horizontal hot zone range, in the subsequent process of selecting the target line segment, the coordinate of the click point clicking the target line segment can be rotated, and whether the target line segment is selected is determined by determining whether the rotated coordinate falls into the horizontal hot zone range. The segment selection angle may be an included angle between the target line segment and the horizontal line segment.
In an alternative embodiment, determining the target hot zone range of the target line segment from the horizontal hot zone range includes: determining the rotation angle of the target line segment in the horizontal direction; rotating the horizontal hot zone range along the direction of the target line segment based on the rotation angle; and taking the rotated horizontal hot zone range as a target hot zone range of a target line segment.
The rotation angle of the target line segment in the horizontal direction may be an included angle between the target line segment and the horizontal line segment.
Optionally, determining the rotation angle of the target line segment in the horizontal direction includes: and determining the rotation angle of the target line segment in the horizontal direction according to the first starting point coordinate and the first ending point coordinate.
For example, the rotation angle of the target line segment in the horizontal direction may be determined based on the existing angle calculation manner, such as a trigonometric function, from the first start point coordinate and the first end point coordinate.
And rotating the horizontal hot zone range along the direction of the target line segment, and taking the horizontal hot zone range rotated based on the rotation angle as the target hot zone range of the target line segment. A schematic of the determination of a target hot zone range is shown in fig. 1D. The line segment ab, the line segment bc, the line segment cd, and the line segment de may be target line segments. Target line segment abThe starting point coordinate is a, the end point coordinate is b, and the line segment ab' is a horizontal line segment of the target line segment ab. The starting point coordinate of the target line segment bc is b, and the ending point coordinate is c. The line segment bc' is a horizontal line segment of the target line segment bc. The starting point coordinate of the target line cd is c, the end point coordinate is d, and the line cd' is a horizontal line of the target line cd. The starting point coordinate of the target line segment de is d, the end point coordinate is e, and the line segment de' is a horizontal line segment of the target line segment de. θ 1 Is the rotation angle of the target line segment ab in the horizontal direction; θ 2 A rotation angle of the target line segment bc in the horizontal direction; θ 3 The rotation angle of the target line cd in the horizontal direction; θ 4 Is the rotation angle of the target line segment de in the horizontal direction. The gray dotted line frame of the horizontal line segment ab ' is the horizontal hot zone range of the horizontal line segment ab ', and the horizontal hot zone range of ab ' is based on theta 1 And after rotation, obtaining a black solid line frame, namely the target hot zone range of the target line segment ab. Similarly, the gray dotted line box of the horizontal line segment bc ' is the horizontal hot zone range of the horizontal line segment bc ', and the horizontal hot zone range of bc ' is based on θ 2 And after rotation, obtaining a black solid line frame, namely the target hot zone range of the target line segment bc. The gray dotted line frame of the horizontal line segment cd ' is the horizontal hot zone range of the horizontal line segment cd ', and the horizontal hot zone range of the cd ' is based on theta 3 And after rotation, obtaining a black solid line frame, namely a target hot zone range of the target line cd. The gray dotted line frame of the horizontal line segment de ' is the horizontal hot zone range of the horizontal line segment de ', and the horizontal hot zone range of the horizontal line segment de ' is based on theta 4 And after rotation, obtaining a black solid line frame, namely the target hot zone range of the target line segment de.
It should be noted that the length of the horizontal line segment may also be determined based on the rotation angle. For example, the first end point coordinates of the target line segment may be rotated to the horizontal direction based on the rotation angle, and the coordinates obtained after the rotation may be taken as the second end point coordinates. A horizontal line segment may be determined from the first endpoint coordinate and the second endpoint coordinate. The process of determining the horizontal line segment by adopting the mode does not need to determine the length of the target line segment, and the determination efficiency of the horizontal line segment is improved.
In an alternative embodiment, after determining the target hot zone range of the target line segment according to the horizontal hot zone range, further comprising: when a click command to a target line segment is detected, acquiring click coordinates of the target line segment; and if the click coordinate is within the target hot area range of the target line segment, placing the target line segment in a selected state.
The click command of the target line segment may be a command selected by a related technician on the target line segment in the View interface. The click coordinates may be click point coordinates when selecting a target line segment in the View interface.
When a click command of the target line segment is detected, a click coordinate corresponding to the target line segment is obtained, and whether the click coordinate is in a target hot area range of the target line segment is judged; if yes, the target line segment is placed in a selected state, and if not, the target line segment is not selected.
It is understood that the horizontal hot zone range may be taken as the target hot zone range of the target line segment without rotating the horizontal hot zone range in the direction of the target line segment correspondence.
In an alternative embodiment, if the click coordinate is within the target hot zone range of the target line segment, then placing the target line segment in the selected state includes: determining the rotation angle of the target line segment in the horizontal direction; rotating the click coordinate based on the rotation angle to obtain a rotation coordinate; if the rotation coordinate is within the horizontal hot zone range of the horizontal line segment, the target line segment is placed in a selected state.
For example, the rotation angle of the target line segment in the horizontal direction may be determined according to the first start point coordinate and the first end point coordinate. And rotating the click coordinate based on the rotation angle to obtain the rotated rotation coordinate. Judging whether the rotation coordinate is in a horizontal hot zone range, wherein the horizontal hot zone range can be used as a target hot zone range of a target line segment; if yes, the target line segment is placed in a selected state, and if not, the target line segment is not selected.

According to the scheme, the horizontal hot zone range of the target line segment in the horizontal direction is determined, and the accuracy of determining the target hot zone range of the target line segment is improved in a mode of determining the target hot zone range according to the horizontal hot zone range. According to the method and the device, the calculation rule of the target hot zone is redefined, the dynamic control of the hot zone range is realized, the situation that the hot zone ranges are overlapped due to the fact that the hot zone ranges corresponding to the target line segments are overlarge when the target line segments are angled is avoided, the situation that the hot zone ranges corresponding to the target line segments are too small to cause difficult selection when the target line segments are horizontal or vertical is avoided, the situation that the target line segments are extensible and good operation experience feeling is brought to related personnel using the line segment selection function is obtained.
