technical field

The invention relates to the technical field of control control of an Android platform, in particular to a method and system for extending an animation display area of an Android platform.

Background technique

In order to improve the user experience, the interface of the Android platform will design a lot of animation effects. In the current technology, most applications use Animation (animation function) to realize the animation of the controls. These animation effects include the movement of the control position, zooming in, zooming out, fading, and a combination of several animations. Most of the controls on the interface inherit a unified View (that is, a view). The layout of these Views includes a parent-child relationship. The ViewGroup, the container of the View, also inherits from the View. The relationship between the View and the ViewGroup is shown in Figure 1. The essence of animating the controls is to animate the View, but due to the interface drawing mechanism in the Android platform, the drawing of the child View is completed by the parent View or ViewGroup. This causes a problem. When a child View is doing a moving animation effect, if the movement range of the child View exceeds the visible area of the parent View, the child View cannot be displayed.

Therefore, the existing technology still needs to be improved and developed.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

Please refer to FIG. 2 . FIG. 2 is a flowchart of a preferred embodiment of the method for extending an animation display area of an Android platform according to the present invention. As shown in FIG. 2, the Android platform animation display area expansion method provided by the embodiment of the present invention includes the steps:

Step S100, creating a ViewGroup, the parent node of the ViewGroup is the root node of the entire interface of the display screen, and the area size of the ViewGroup is the largest area that the View can move on the entire interface of the display screen;

During specific implementation, the area of the ViewGroup is equal to the area of the display screen of the smart terminal, that is, the area size of the ViewGroup is the largest area that the View can move on the entire interface of the display screen. For convenience, an area with the same size as the display screen of the smart terminal can be created and used as the container of the View (that is, the ViewGroup), and no changes are required to the previously implemented layout.

Step S200: Obtain and copy the child View to be animated in the parent View, obtain the corresponding child View copy, and add the child View copy to the ViewGroup; wherein, the display of the child View copy on the smart terminal The position in the screen is the same as the position of the sub-View in the display screen;

Step S300 , when it is monitored that the sub-View performs a moving animation display, the position information of the sub-View copy is updated synchronously with the position information of the sub-View.

In step S300, the position information of the sub-View replica is updated synchronously with the position information of the sub-View, which means that when the sub-View is monitored for moving animation display, the sub-View replica is driven to perform synchronous movement, And the sub-View copy and the sub-View remain relatively still.

Further, in the step S300, when it is detected that the child View moves outside the area of the parent View, the part of the child View located in the area of the parent View is displayed, and the child View is located in the area of the parent View. The part outside the area of the parent View is not displayed, and the copy of the child View is displayed normally.

In the prior art, since the child View cannot be displayed beyond the area of the parent View, the reason is that the area of the parent View is too small, so the size of the area of the parent View can be adjusted, which brings a problem that the area of the parent View changes. The layout of the sub-View should also be adjusted when the size is large. If there are multiple View controls on the interface, the layout calculation will bring great inconvenience and the previously designed layout interface needs to be re-adjusted.

In the embodiment of the present invention, when moving animation or zooming in animation effect is performed on a control (ie, a child View or a copy of the child View, etc.), when the area of the child control exceeds the area of the parent control, an identical copy of the child control is obtained by duplicating the child control , and set the maximum visible range of the container where the sub-control copy is located to the size of the display screen of the smart terminal. In the invisible position of the child control, after the child control is completed by the copy of the child control, the effect that the child control can also be displayed in the area beyond the parent control is achieved, and the previous layout changes are relatively small, and the implementation is relatively simple.

Step S213, according to the getLocationOnScreen interface, obtain the first horizontal coordinate of the left border of the sub View relative to the left border of the display screen, and the first vertical coordinate of the upper border of the sub View relative to the upper border of the display screen;

Step S214, according to the getLocationOnScreen interface, obtain the second horizontal coordinate of the left border of the ViewGroup relative to the left border of the display screen, and the second vertical coordinate of the upper border of the ViewGroup relative to the upper border of the display screen;

Step S215: Obtain the third horizontal coordinate of the left border of the child View copy relative to the left border of the ViewGroup according to the difference between the second horizontal coordinate and the first horizontal coordinate, and obtain the third horizontal coordinate of the left border of the ViewGroup according to the second vertical coordinate. The difference from the first vertical coordinate obtains the third vertical coordinate of the upper boundary of the child View copy relative to the upper boundary of the ViewGroup.

As a second specific embodiment of step S200, the step S200 specifically includes:

Step S221, obtaining the child View of the animation to be created in the parent View, and duplicating it to obtain the corresponding child View copy;

Step S222, adding a sub-View copy to the ViewGroup;

Step S223, according to the getLocationOnScreen interface, obtain the fourth horizontal coordinate of the right border of the sub-View relative to the right border of the display screen, and the fourth vertical coordinate of the lower border of the sub-View relative to the lower border of the display screen;

Step S224, according to the getLocationOnScreen interface, obtain the fifth horizontal coordinate of the right border of the ViewGroup relative to the right border of the display screen, and the fifth vertical coordinate of the lower border of the ViewGroup relative to the bottom border of the display screen;

Step S225: Obtain the sixth horizontal coordinate of the right border of the sub-View copy relative to the right border of the ViewGroup according to the difference between the fifth horizontal coordinate and the fourth horizontal coordinate, and obtain the sixth horizontal coordinate of the right border of the ViewGroup according to the fifth vertical coordinate. The difference from the fourth vertical coordinate obtains the sixth vertical coordinate of the lower boundary of the child View copy relative to the lower boundary of the ViewGroup.

In the first specific embodiment of step S200, the positioning is realized by taking the left border and the upper border of the display screen as a reference, and in the second specific embodiment of step S200, the right border and the lower border of the display screen are taken as a reference. achieve positioning.

Further, in the step S300, the sub-View copy and the sub-View are scaled synchronously, and the sub-View copy and the sub-View keep the same size.
