Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The display control method and the display control device provided by the disclosure are suitable for scenes in which content is displayed for scrolling views including a head view and a list view. The display control methods provided by the embodiments of the present disclosure may be executed by a display control apparatus, where the apparatus may be implemented by software and/or hardware and specifically configured in an electronic device.
For ease of understanding, the display control methods provided by the present disclosure will be described in detail first.
Referring to fig. 1A, a display control method includes:
s101, determining state information of a head view in a scrolling view; wherein the scroll view also includes a list view.
See the schematic of the display page shown in fig. 1B. The display page is displayed through a display screen (corresponding to a black solid rectangular frame in the drawing, it should be noted that the black solid rectangular frame in the schematic diagram of the subsequent display page or the schematic diagram of the sliding process of the display page also represents the display screen, and will not be described in detail later), and the display page comprises a scrolling view for sliding display page contents. Wherein the scrolling view includes a head view for displaying head content; the scroll view also includes a list view for presenting list content. The list view may be provided with at least one sub-list view in parallel, and the sub-list view may be switched by sliding left and right. The slideable content may be scroll-presented in full-size by a slide up and down operation (the arrow shown in the figure indicates the direction of the slide) by the operator.
It should be noted that, when the list view is provided with at least two sub-list views, the list view related in the disclosure is the currently displayed sub-list view. For ease of understanding, the present disclosure is described by way of example with one list view disposed in a scroll view, and should not be construed as limiting the present disclosure.
Alternatively, the head view may slide with the scrolling view and the list view may slide with the head view. When the head view hovers over the presentation, the list view may slide itself to present hidden content in the slidable content.
Wherein the state information of the head view may include at least one of a head state, an intermediate state, and a bottom state for characterizing a current location of the view.
For example, the status information of the head view may be directly acquired; or, acquiring state reference information of the head view, and determining the state information of the head view according to the state reference information.
In an alternative embodiment, the state reference information may include a sliding position of the head view, and the corresponding determination of the state information of the head view in the scroll view may be: acquiring a sliding position of a head view; status information of the head view is determined according to the sliding position of the head view.
Wherein the sliding position of the head view may be determined by the operating system invoking the setup interface.
For example, if the sliding position of the head view satisfies the head state condition, determining that the head view is in the head state; if the sliding position of the head view meets the bottom state condition, determining that the head view is in a bottom state; if the sliding position of the head view meets the intermediate state condition, determining that the head view is in the intermediate state. The head state condition, the bottom state condition and the intermediate state condition can be set by a technician according to experience values or can be determined through a large number of experimental adjustment, and only the condition that the state conditions are not overlapped is ensured.
Specifically, if the sliding position of the head view is not smaller than the head threshold of the scrolling view, determining that the head view is in a head state; if the sliding position of the head view is not greater than the bottom threshold value of the scrolling view, determining that the head view is in a bottom state; if the head view is greater than the bottom threshold of the scroll view and less than the head threshold of the scroll view, then the head view is determined to be in an intermediate state. When the head threshold of the scrolling view slides up and down (namely slides along the content display direction), the maximum coordinate value of the sliding position of the scrolling view; the bottom threshold of the scroll view is the minimum coordinate value of the sliding position of the scroll view when sliding up and down.
It can be understood that the determination of the state information of the head view is performed by acquiring the sliding position of the head view, so that the state information determination mechanism of the head view is perfected. In addition, the existing operation system is not required to be changed, the sliding position acquisition function interface is directly multiplexed, and convenience in the display control process is improved.
S102, acquiring a page sliding direction and a page sliding position.
The page sliding direction is used for representing the operation direction when the operation party slides and displays the page.
By way of example, the speed acquisition interface may be invoked to acquire a sliding speed, and characterize the page sliding direction according to the positive or negative of the sliding speed.
Wherein the page sliding direction includes an upward sliding and a downward sliding. The upward sliding is the sliding along the content display direction and the direction close to the head view; the downward sliding is the sliding along the content display direction and away from the head view direction.
The page sliding position is used for representing the relative position relation between the display page and the initial sliding position. The page sliding position may include position relation data of an initial sliding position of the list view relative to the list view, which is used for representing a change condition of the list view relative to an initial sliding position of the list view, and/or position relation data of an initial sliding position of the scroll view relative to the scroll view, which is used for representing a change condition of the scroll view relative to an initial sliding position of the scroll view. Wherein the initial sliding position of the list view and the initial sliding position of the scroll view may be the same or different. For ease of calculation, the initial sliding positions of both are usually set to (0, 0).
S103, performing sliding control on the list view or the scrolling view according to the state information, the page sliding direction and the page sliding position.
Optionally, the sliding control on the list view or the scroll view may include selecting a target view from the list view and the scroll view, and performing the sliding control on the target view.
Optionally, the sliding control on the list view or the scroll view may include determining a sliding start timing or a sliding end timing of the list view or the scroll view.
Illustratively, according to the state information, the page sliding direction and the page sliding position, selecting a target view from the list view and the scroll view, and performing sliding control on the selected target view to prohibit sliding of the non-target view.
In a specific implementation manner, the target view corresponding to the state information, the page sliding direction and the page sliding position can be determined based on a preset view matching relationship. The view matching relationship can be set by a technician according to the needs or experience values or can be determined through a plurality of experimental adjustment.
Illustratively, the sliding position of the reset list view or the scroll view is controlled according to the state information, the page sliding direction, and the page sliding position, thereby determining the sliding termination timing.
In a specific implementation manner, the sliding termination time corresponding to the state information, the page sliding direction and the page sliding position may be determined based on a preset sliding termination time matching relationship. The sliding termination timing matching relationship can be set by a technician according to the needs or experience values or can be determined through a large number of experimental adjustments.
According to the embodiment of the disclosure, the state information of the head view, the page sliding direction and the page sliding position are introduced to perform sliding control on the list view or the rolling view, so that sliding display of page contents is realized, the state determination of the list view is not needed, and a new idea is provided for display control. In addition, the state determination process of the list view is complicated, so that the state determination process of the list view is not required to be carried out, and the operation amount of the display control process is simplified, so that the convenience of the display control process is improved. Meanwhile, the technical scheme disclosed by the invention is also suitable for the situation that a plurality of parallel list views exist, different list views are subjected to display control in the same mode, other redundant operations are not required when the list views are switched, and the display control process of each list view is not affected, so that the display control method disclosed by the invention has more universality.
Based on the technical schemes, the present disclosure also provides an alternative embodiment. In this alternative embodiment, the process of sliding control of the list view or scroll view is optimized and improved to perfect the sliding control mechanism of the list view or scroll view.
It should be noted that, in the embodiments of the present disclosure, details are not described, and reference may be made to the descriptions of the foregoing embodiments, which are not described herein.

Referring to the schematic diagram of the sliding process of the display page shown in fig. 2B, if the head view is in the bottom state, the sliding position of the list view is not lower than the bottom threshold value (generally equal to the bottom threshold value) of the list view, which indicates that there is still an upward sliding space of the head content in the head view, at this time, if sliding upward, the scrolling view may be controlled to slide upward, so as to drive the head view and the list view to slide upward in association, and the list view is prohibited from sliding upward independently, in this process, the head view transitions from the bottom state to the intermediate state; the sliding position of the scroll view changes and the sliding position of the list view does not change.
In another specific implementation, if the state information is a bottom state, the sliding position of the list view is not lower than the bottom threshold of the list view, and the page sliding direction is a downward sliding, the list view is controlled to slide downward, the head content in the head view hovers over a preset hovering area, and scrolling view sliding is prohibited.
Referring to the schematic diagram of the display page sliding process shown in fig. 2C, when the head view is in the bottom state and the sliding position of the list view is not lower than the bottom threshold value (generally equal to the bottom threshold value) of the list view, it indicates that there is no downward sliding space of the head content in the head view, and at this time, if the scrolling view responds to the sliding, the head content overflows downward, so that the head content in the head view can be controlled to hover in a preset hover region in the head view, and the list view is controlled to slide downward, so that the scrolling view is prohibited from sliding. In this process, the head view is always in the bottom state, the sliding position of the scroll view is unchanged, and the sliding position of the list view is changed.
In another specific implementation, if the state information is in a bottom state and the sliding position of the list view is lower than the bottom threshold of the list view, the list view is controlled to slide according to the page sliding direction, and the scrolling view is prohibited from sliding.
Referring to a schematic view of a display page shown in fig. 2D, when the head view is in a bottom state and the sliding position of the list view is lower than the bottom threshold of the list view, it indicates that the list view has left the initial sliding position, and at this time, if the scrolling view is controlled to slide, the situation that the head content and the list content slide in an overlapping manner will occur, so as to affect the viewing experience of the user, therefore, the scrolling view can be controlled to slide up or down according to the page sliding direction, and the scrolling view is prohibited from sliding, so that the situation that the list view and the scrolling view slide together is avoided. At this time, the sliding position of the scroll view is unchanged, and the sliding position of the list view is changed.
In another specific implementation, if the state information is a head state, the sliding position of the list view is not higher than the bottom threshold of the list view, and the page sliding direction is sliding downward, the scrolling view is controlled to slide downward, and the list view is prohibited from sliding.
Referring to a schematic view of a display page shown in fig. 2E, if the head view is in a head state and the sliding position of the list view is not higher than the bottom threshold of the list view, it indicates that there is a downward sliding space of the head content in the head view, and at this time, if sliding downward, the scroll view may be controlled to slide downward, so as to drive the head view and the list view to slide downward in association, and prohibit the list view from sliding downward independently. In the process, the head view transitions from the head state to an intermediate state; the sliding position of the scroll view changes and the sliding position of the list view does not change.
In another alternative embodiment, if the status information is a head status, the sliding position of the list view is not higher than the bottom threshold of the list view, and the page sliding direction is sliding upwards, the list view is controlled to slide upwards, the head content in the head view hovers over the preset hovering area, and scrolling view sliding is prohibited.
Referring to a schematic view of a display page in fig. 2F, if the head view is in the head state, the sliding position of the list view is not higher than the bottom threshold value (generally equal to the bottom threshold value) of the list view, which indicates that there is no upward sliding space of the head content in the scroll view, and if the scroll view responds to the sliding, the head content overflows upward, at this time, the head content in the head view is controlled to hover over a preset hover area in the head view, and the list view is controlled to slide upward, so that the scroll is prohibited from attempting to slide. In this process, the head view is always in the head state, the sliding position of the scroll view is unchanged, and the sliding position of the list view is changed.
In yet another specific implementation, if the status information is a head status and the sliding position of the list view is higher than the bottom threshold of the list view, the list view is controlled to slide according to the page sliding direction, and the scrolling view is prohibited from sliding.
Referring to a schematic view of a display page shown in fig. 2G, when the head view is in the head state and the sliding position of the list view is higher than the bottom threshold of the list view, it indicates that the list view has left the initial sliding position, and at this time, if the scrolling view is controlled to slide, the situation that the head content and the list content slide in an overlapping manner will occur, which affects the viewing experience of the user. Therefore, the list view can be controlled to slide upwards or downwards according to the page sliding direction, and the scrolling view is forbidden to slide, so that the situation that the list view and the scrolling view slide together is avoided. At this time, the sliding position of the scroll view is unchanged, and the sliding position of the list view is changed.
In yet another specific implementation, if the state information is an intermediate state, the scrolling view is controlled to slide in the page sliding direction and the list view is prohibited from sliding.
Referring to a schematic view of a display page sliding process shown in fig. 2H, when the head view is in an intermediate state, it indicates that there is still an upward sliding space of the head content in the head view, and at this time, if the list view is controlled to slide, a situation that the head content and the list content slide in an overlapping manner will occur, which affects the viewing experience of the user. Therefore, the scrolling view can be controlled to slide upwards in response to the page sliding direction, so that the head view and the list view are driven to slide upwards in an associated mode, and the list view is prevented from sliding autonomously. In the process, the head view transitions from the intermediate state to the head state; the sliding position of the scroll view changes and the sliding position of the list view does not change.
Referring to a schematic view of a display page sliding process shown in fig. 2I, when the head view is in an intermediate state, it indicates that there is still a downward sliding space of the head content in the head view, and at this time, if the list view is controlled to slide, a situation that the head content and the list content slide in an overlapping manner will occur, which affects the viewing experience of the user. Therefore, the scrolling view can be controlled to slide downwards in response to the page sliding direction, so that the head view and the list view are driven to slide downwards in an associated mode, and the list view is prevented from sliding autonomously. In the process, the head view transitions from the intermediate state to the bottom state; the sliding position of the scroll view changes and the sliding position of the list view does not change.
It can be understood that under the condition of different state information, page sliding directions and sliding positions of the list views, the above technical schemes select different target views from the list views and the scroll views, enrich and perfect selection mechanisms of the target views, realize orderly alternate control of the list views and the scroll views, avoid the situation that head contents and the list contents are overlapped and scrolled, ensure that the head contents of the head views can naturally slide up and down along with the list contents, and improve the use experience of users.
According to the method and the device, sliding control operation on the list view or the rolling view is refined into selection of the target view from the list view and the rolling view according to the state information, the page sliding direction and the page sliding position, and further the target view is controlled to slide according to the page sliding direction, and non-target view sliding is forbidden, so that dimensions are selected from the views, and display control on a page display process is achieved.
Based on the above technical solutions, the present disclosure further provides an optional embodiment, in which the sliding position of the list view or the sliding position of the scroll view in the sliding display process is reset, so as to avoid occurrence of a sliding out-of-bounds condition.
Referring to fig. 3, a display control method includes:
s301, determining state information of a head view in a scrolling view; wherein the scroll view also includes a list view.
S302, acquiring a page sliding direction and a page sliding position.
S303, controlling the sliding position of the reset list view or the sliding position of the scroll view according to the state information, the page sliding direction and the page sliding position.
Optionally, controlling the sliding position of the reset list view according to the status information, the page sliding direction and the page sliding position may include: and if the target view is a list view, controlling to reset the sliding position of the rolling view to the edge sliding position corresponding to the page sliding direction according to the sliding position or the page sliding direction of the list view.
In a specific implementation, if the sliding position of the list view is greater than the bottom threshold of the list view or the page sliding direction is sliding upwards in the state that the state information is the head state, the sliding position of the scroll view is reset to the head threshold of the scroll view.
When the head view is in the head state, if the sliding position of the list view is greater than the bottom threshold value of the list view, the list view is indicated to slide down, and at this time, if the scrolling view is controlled to slide, the situation that the head content and the list content slide in an aliasing manner will occur, so that the viewing experience of a user is affected. Therefore, it is necessary to achieve the purpose of prohibiting the scroll view from sliding up by controlling the sliding position of the scroll view to be reset to the head threshold of the scroll view.
For example, if the initial sliding position of the scroll view is (x, y_bottom), the maximum sliding position of the scroll view is (x, y_top); the bottom threshold of the corresponding scroll view is y_bottom, and the head threshold of the scroll view is y_top (i.e., y_bottom+h). For example, x may be 0, y_bottom may be 0, and y_top may be h. If the initial slide position of the list view is (X, Y_bottom). For example, X may be 0 and Y_bottom may be 0.
If the sliding position current_y > y_bottom of the list view, the sliding position contentOffset of the scroll view is reset to (x, y_top). Since the present disclosure relates to only up-and-down sliding, only the y coordinate in the sliding position (x, y) of the scroll view is reset, and the x coordinate is not reset.
When the head view is in the head state, at this time, no upward sliding space of the head content exists in the scrolling view, and if the page sliding direction is upward sliding, the head content will overflow upward. Therefore, it is necessary to achieve the purpose of prohibiting the scroll view from sliding up by controlling the sliding position of the scroll view to be reset to the head threshold of the scroll view.
Continuing the previous example, the sliding direction is characterized by the positive and negative of the sliding speed of the operator, and v <0 is defined as sliding up, v >0 is sliding down. If v <0, the sliding position contentOffset of the scroll view is reset to (x, y_top).
In another specific implementation, if the sliding position of the list view is smaller than the bottom threshold or the page sliding direction is sliding downward in the state that the state information is in the bottom state, the sliding position of the scroll view is reset to the bottom threshold of the scroll view.
When the head view is in the bottom state, if the sliding position of the list view is smaller than the bottom threshold value, the list view is indicated to slide down, and at this time, if the scrolling view is controlled to slide, the situation that the head content and the list content slide in an aliasing manner will occur, so that the viewing experience of the user is affected. Therefore, the purpose of prohibiting the scroll view from sliding down needs to be achieved by controlling the sliding position of the scroll view to be reset to the bottom threshold of the scroll view.
Continuing the previous example, if the sliding position current_y < y_bottom of the list view, the sliding position contentOffset of the scroll view is reset to (x, y_bottom).
When the head view is in the bottom state and no downward sliding control of the head content exists in the scrolling view, if the page sliding direction is downward sliding, the head content will overflow downward. Therefore, the purpose of prohibiting the scroll view from sliding down needs to be achieved by controlling the sliding position of the scroll view to be reset to the bottom threshold of the scroll view.
Continuing with the previous example, if v >0, the sliding position contentOffset of the scroll view is reset to (x, y_bottom).
Or alternatively, controlling the sliding position of the reset list view according to the status information, the page sliding direction and the page sliding position may include: and if the page slides to the edge area of the rolling view, controlling the sliding position of the rolling view to be reset to the edge sliding position corresponding to the page sliding direction according to the sliding position of the rolling view.
Continuing the previous example, if y.gtoreq.y_top of the sliding position contentOffset of the scroll view is in the head state, the sliding position contentOffset of the scroll view is reset to (x, y_top). If y of the sliding position contentOffset of the scroll view is less than or equal to y_bottom, the head view is in a bottom state, and the sliding position contentOffset of the scroll view is reset to (x, y_bottom).
It can be understood that by refining the reset operation of the sliding position of the scrolling view under different conditions, the control mechanism of the sliding position of the scrolling view is perfected and enriched, and the situation that the content in the head view and the list view are in aliasing sliding is avoided, so that the head content in the head view can naturally slide up and down along with the list view, hover is achieved when the edge area is reached, and the use experience of a user is improved.
Optionally, controlling the sliding position of the reset list view according to the status information, the page sliding direction and the page sliding position may include: and if the state information is in the bottom state, controlling to reset the sliding position of the list view to the initial sliding position of the list view according to the sliding position of the list view and the page sliding direction.
In a specific implementation manner, if the sliding position of the list view is not less than the bottom threshold value and the page sliding direction is sliding upwards in the state that the state information is in the bottom state, the sliding position of the list view is reset to the initial sliding position of the list view.
In the head view in the bottom state, indicating that there is no downward sliding space for the head content in the head view, thus prohibiting the scrolling view from responding to the downward sliding and responding to the upward sliding; if the sliding position of the list view is greater than the bottom threshold, indicating that the list view has been slid up; in order to avoid the situation that the head content and the list content slide in an overlapping way, the watching experience of a user is affected, and when the page sliding direction is upward sliding, the sliding position of the list view is reset to the initial sliding position of the list view, so that the aim of prohibiting the list view from sliding upwards is fulfilled.
Continuing the previous example, if the sliding position current_y of the list view is greater than or equal to y_bottom, and the operator sliding speed v <0, the sliding position sub_contentoffset of the list view is reset to (X, y_bottom). Since the present disclosure relates to only up-and-down sliding, only the Y coordinate in the sliding position (X, Y) of the list view is reset, and the X coordinate is not reset.
Or alternatively, controlling the sliding position of the reset list view according to the status information, the page sliding direction and the page sliding position may include: and if the state information is in the intermediate state, resetting the sliding position of the list view to the initial sliding position of the list view.
If the head view is in the middle state, it indicates that there are an upward sliding space and a downward sliding space of the head content in the head view, and at this time, if the list view is controlled to slide, the situation that the head content and the list content slide in an aliasing manner will occur, which affects the viewing experience of the user, and the sliding position of the list view is reset to the initial sliding position of the list view, so as to achieve the purpose of prohibiting the list view from sliding upwards.
Continuing the previous example, if the head view is in the intermediate state, i.e. the y-coordinate contentoffset_y in the sliding position contentOffset of the scroll view, the following condition is satisfied: y_bottom < contentoffset_y < y_top, the slide position sub_contentoffset of the list view is reset to (X, y_bottom).
It can be understood that by refining the reset operation of the sliding position of the list view under different conditions, the control mechanism of the sliding position of the list view is perfected and enriched, and the situation that the head view and the content in the list view slide in an aliasing manner is avoided, so that the head content in the head view can naturally slide up and down along with the list view and hover when reaching an edge area, and the use experience of a user is improved.
According to the embodiment of the disclosure, the sliding control operation on the list view or the rolling view is refined into the control of resetting the sliding position of the list view or the sliding position of the rolling view according to the state information, the page sliding direction and the page sliding position, so that the dimension is controlled from the view sliding position, the display control on the page display process is realized, the single sliding control on the list view and the rolling view is facilitated, and the occurrence of the head content in the head view and the list content aliasing sliding of the list view is avoided, so that poor use experience is brought to a user.
