Description
Technical Field
The invention relates to the technical field of achievement of a trotting horse lamp effect, in particular to a trotting horse lamp effect achieving device and method based on an Android platform.
Background
Over the past few years, the Android platform has developed rapidly. Android platforms are more and more stable, security holes are gradually repaired by google companies, and the Android platforms gradually mature. Therefore, many platforms begin to be transplanted to the Android platform, so that the existing software of the original platform also needs to be realized again on the Android platform. However, the Android platform is not absolutely perfect, and the poor hardware processing performance is a significant disadvantage compared with other platforms. Due to the defect, the Android platform has great limitations in processing big data operation, picture processing and displaying and the like. Conventionally, the Android platform trotting horse lamp effect is difficult to achieve perfectly, which is caused by the limitation.
In the prior art, the ticker effect is realized by using an ellipsize attribute (an attribute of realizing the ticker effect by using a TextView control (a view control for displaying characters by using an Android platform) provided by google corporation; the realization principle of the technical scheme is as follows: if the ellipsosize attribute is set in the TextView, the TextView is initialized, and then is analyzed through AttributeSet (attribute set class realized by Google), once the value of the ellipsosize is analyzed to be legal, the number of characters which can be displayed on the TextView is expanded, the length of the characters is larger than the width of the TextView view, then the characters are repeatedly drawn through Canvas (Canvas for drawing by an Android platform), and the coordinates of the drawing starting point are recalculated during each drawing, so that the scrolling effect is achieved. Different from other effects of drawing the trotting horse by using Canvas, the technical scheme does not need the developer to realize the trotting horse by himself, but is provided by Google company, and the developer only needs to simply set one ellipsize attribute. However, the trotting horse lamp realized by the technical scheme has poor effect, and has obvious jitter and blockage effects in the operation process.
In addition, in the prior art, a Canvas is also proposed to dynamically draw contents to be displayed so as to generate the effect of a trotting horse; and the realization method is to draw by dividing time equally or by dividing displacement equally. However, the proposal also has the problems of poor effect of the revolving scenic lantern, obvious jitter and blockage effect in the operation process and the like.

Other aspects and features of the present invention will become apparent from the following detailed description, which proceeds with reference to the accompanying drawings. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention. It should be further understood that the drawings are not necessarily drawn to scale and that, unless otherwise indicated, they are merely intended to conceptually illustrate the structures and procedures described herein.
Drawings
The following detailed description of embodiments of the invention will be made with reference to the accompanying drawings.
Fig. 1 is an overall block diagram of a related art solution for implementing static picture display by using a cycleview control.
Fig. 2 is a schematic module diagram of a device for implementing a lantern effect based on an Android platform according to an embodiment of the present invention.
Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Specifically, refer to fig. 1, which is a general block diagram of implementing a static picture display by using a cycleview control in the related art. As shown in fig. 1, it is mainly divided into three major parts: a DataSet (DataSet) module 11, an Adapter (Adapter)13, and a RecycleView control 15. Wherein, the RecycleView control 15 is a container control; the adapter 13 is mainly used to bind the data in the data set module 11 and the child view displayed by the RecyclerView control 15, and on one hand, it can be used to monitor the data in the data set module 15 for changes, and on the other hand, it can be used to notify the RecyclerView control 15 when there is a change in the data set module 11. However, in the overall block diagram of fig. 1, the content of the display screen when the cyclerview control 15 associates with the data set block 11 through the adapter 13 is static and has no ticker effect.
Therefore, in order to implement the trotting horse light effect, the following embodiment of the present invention will describe in detail a technical solution for implementing the trotting horse light effect based on the Android platform with reference to fig. 2.
Referring to fig. 2, in order to achieve the ticker effect of local or network data, in this embodiment, a data processing module 24a and a smooth scrolling module 24b are added on the basis of fig. 1, and a layout manager (layout manager)151 is configured for the cycleview control 15, so that the display content of the user interface can be smoothly scrolled in a specified direction.
The data processing module 24a is configured to implement the function of circularly searching the sub-views, and the working principle thereof is as follows: if the reclerview control 15 has a plurality of, for example, n sub-views to be displayed, and the sub-view currently presented to the user is the mth sub-view, then the sub-view data corresponding to the reclerview control is in the memory block P at this time, if the nth sub-view is to be searched, the (m + 1) th sub-view needs to be drawn into the memory block P through a Canvas, and then the (m + 2) th, the (m + 3) th, the (m + 4) th, …, and the nth sub-view are sequentially displayed; when drawing to the nth sub-view, the RecycleView control 15 knows that this is the sub-view it finally finds, and therefore does not continue to find downwards; if the cyclic search is needed, the method is similar to the method mentioned above, and only after the last sub-view is found, the 1 st sub-view is drawn to the memory block P; as for the display content data of each sub-view, it is the notification adapter 13 that is obtained from the data set module 11, and the data set module 11 is the data source that needs to display the ticker effect.
The smooth scrolling module 24b is used for implementing the function of smoothly scrolling the sub-views, and the working principle thereof is as follows: the two main technical means used are to calculate how many pixels need to be moved per unit time (e.g. per second) each time the data processing module 24a searches for a sub-view, and to calculate a displacement value of the movement for a preset time length (e.g. one second). In the aforementioned cyclic search, each search is actually a process of drawing the memory block P through a Canvas, and therefore calculation is required, for the same sub-view, what is the initial coordinate of each frame of the Android system during each drawing, and what number of pixels each frame should move in a certain direction for drawing, so that what number of pixels each second should move can be calculated, and the calculated pixel value of each second movement is actually the speed of the sub-view displayed by the recclerview control 15 based on the movement of the pixel point. The end result of the dynamic computation and dynamic rendering is the movement of the display contents of the RecycleView control 15. However, why the present embodiment proposes to use the "displacement value for a preset time length of movement? The reason is that: if the drawing and the moving are simply carried out according to the starting coordinates, the CPU performance is reduced due to the fact that the frames drawn by the CPU per second are inconsistent and frequent logic operation and image drawing are added, the number of the frames drawn per second is large, and therefore obvious frame loss and frame jamming are generated, and shaking and jamming phenomena are caused. The benefits of calculating the displacement value are: if the calculated pixel values which need to move every second are inconsistent, namely the speeds are inconsistent, as long as the displacements can be ensured to be approximately equal, the images drawn in unit time do not have larger contrast in visual effect, the moving pixel values are large, namely the speed is high, a few frames of images are drawn (corresponding to the image frame drawing speed is reduced), the moving pixel values are small, namely the speed is low, a few frames of images are drawn (corresponding to the image frame drawing speed is increased), and therefore the effect of smooth rolling is achieved.
In addition, the layout manager 151 is configured to control the scrolling Direction of the sub-view of the recycleview control 15 through a Direction attribute encapsulated therein; for example, if the Direction attribute is set to Up, the sub-view of the recycleview control 15 will continuously calculate how many pixels and displacements should be moved Up each time in the vertical Direction for drawing during the smooth scrolling process, and the implementation of other directions is similar to this, so that the effect of the trotting lantern in four directions, i.e. Up, down, left and right, can be achieved.
With respect to the aforementioned data set module 11, adapter 13, data processing module 24a, smooth scrolling module 24b and RecycleView control 15 configured with layout manager 151 shown in FIG. 2, in short, the data processing module 24a is configured to search sub-views in a loop and sequentially draw the searched sub-views to the memory block by using, for example, a Canvas control, the adaptor 13 is configured to bind the data in the data set module 11 with the sub-views searched by the data processing module 24a, the smooth scrolling module 24b is configured to control an image frame drawing speed when the sub-views are drawn by the data processing module 24a by using the Canvas control memory block based on a speed of pixel point movement and a displacement of preset time length movement to realize smooth scrolling of the sub-views, the reclerview control 15 is configured to scroll the sub-views drawn by the data processing module 24a, and the layout manager 151 is configured to set a sub-view scrolling direction. Furthermore, it is worth mentioning that the respective functional modules are implemented by software, for example.
In summary, by setting the data processing module 24a and the smooth scrolling module 24b, the Android platform can realize the lantern moving effect by using the cycleview control, and the lantern moving effect and the inching effect of the Android platform can be obviously improved; further, by configuring the layout manager 151 to set the sub-view scrolling direction, a ticker effect in a plurality of directions, for example, four directions of up, down, left, and right, can be achieved. In addition, the recycleview control 15 has the characteristic of realizing reusability/recyclability of the sub-views, and each reusable sub-view corresponds to one data buffer area on the RAM, so that even if the data in the data set module 11 is huge, the existing buffer areas are only reused without additional memory space, and thus, a large memory is not occupied, and the operation processing of large data is not influenced.
Finally, it is worth mentioning that the technical scheme for realizing the marquee effect of the embodiment of the invention is not limited to the fields of mobile phones, tablet computers, LED display screen systems and the like, but also can be used in the industries and fields of televisions and other applications of the marquee effect.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
