Detailed Description
FIG. 1 is a schematic diagram of an operating environment of a multi-touch processing system according to a preferred embodiment of the invention. The multi-touch processing system 11 runs on an electronic device 1. The electronic device 1 further comprises at least a touch screen 10, a processor 12, and a storage device 13. The touch screen 10 supports a multi-touch technology, and can recognize and detect operations such as simultaneous clicking and touching performed by at least two fingers. The processor 12 is configured to execute each functional module in the multi-touch processing system 11. The storage device 13 is used for storing various types of information of the electronic device 1. In this embodiment, the multi-touch processing system 11 is installed in the storage device 13 in the form of a software program or instructions and executed by the processor 12.
FIG. 2 is a functional block diagram of a multi-touch processing system according to a preferred embodiment of the invention. The multi-touch processing system 11 includes a monitoring module 110, a recording module 111, an analyzing module 112, a determining module 113, and a processing module 114. The modules referred to in the present invention are program segments of an electronic device that perform a specific function, and are more suitable than programs for describing the execution process of software in the electronic device, so that the following description of the software in the present invention is described as modules.
The monitoring module 110 is configured to monitor a touch event on the touch screen 10 and identify an operation of the touch event on the touch screen 10, such as a single-touch operation or a multi-touch operation. In the preferred embodiment, the monitoring module 110 creates a container view (ContainerView) for intercepting and listening touch events, the container view is started up when the electronic device 1 is powered on, and other applications are included in the container view after being started up. When the user touches the touch screen 10 with a finger, the container view first monitors for a touch (touch) event. The container view intercepts the touch event and does not distribute (dispatch) the touch event to the controls of the top-level window currently displayed by the electronic apparatus 1.
It should be noted that a single touch of a finger on the touch screen 10 may trigger the ACTION of ACTION _ DOWN first, or immediately after the ACTION _ MOVE, and then trigger the ACTION _ UP after the finger is lifted, and each touch may include the above-mentioned series of ACTIONs. The monitoring module 110 obtains touch coordinates of one or more touches included in the touch event, stores touch coordinate values of a series of ACTIONs of the one or more touches in a group of data structures corresponding to the touches, and identifies whether the touch event is a single-point touch or a multi-point touch by analyzing coordinate values when the ACTION _ DOWN and the ACTION _ UP are triggered in the touch event. If there are multiple different X, Y values when the ACTIONs of ACTION _ DOWN and ACTION _ UP are triggered, the monitoring module 110 identifies the touch event as a multi-touch operation, otherwise, identifies the touch event as a single-touch operation.
The recording module 111 is configured to record information of the touch event in a first list when the touch event is identified as a multi-touch operation. In the preferred embodiment, the recording module 111 sequentially records coordinate values of the touch screen 10 operated by the multiple touches included in the touch event in the first list. It should be noted that, when the touch event is identified as a single-touch operation, the recording module 111 does not perform operations such as recording, and the processor 12 assigns the touch event to a specific control in the currently displayed top-level view of the electronic apparatus 1 in the view container for processing.
The parsing module 112 is configured to parse the information of the touch event recorded in the first list to obtain a plurality of controls triggered by the touch event, and obtain parameters of the plurality of controls. In the preferred embodiment, the parsing module 112 determines the trigger range of each control in the top-level window currently displayed by the electronic device 1 by obtaining the screen coordinates of all the controls in the top-level window currently displayed, and compares the coordinate values of the multi-touch operation recorded in the first list with the determined trigger range of each control to determine the plurality of controls triggered by the touch event. In the preferred embodiment, the parsing module 112 may obtain the screen coordinates of each control by first obtaining the window coordinates of the top-level window currently displayed by the electronic device 1, then obtaining all the controls in the top-level window and obtaining the layout coordinates of each control, and using the window coordinates of the top-level window and the layout coordinates of each control. The parameters of the control may include, but are not limited to, a control ID, a class name, touch coordinate values, and the like of the control.
The judging module 113 is configured to judge whether there is a similar control in the multiple controls according to the obtained parameters of the multiple controls. In this preferred embodiment, the determining module 113 determines that there is a similar control in the plurality of controls by comparing the class names of the plurality of controls, and when two or more of the plurality of controls have the same class name. It should be noted that, when the determining module 113 determines that there is no similar control in the plurality of controls, the processor 12 assigns the touch event to the current display top view of the electronic device 1 in the view container, and the electronic device 1 processes the control according to the original processing method.
The processing module 114 is configured to record the determined control IDs and touch coordinate values of the similar controls in a second list, and sequentially process the controls in the second list. In this preferred embodiment, the processing module 114 sequentially obtains a control ID and a touch coordinate value of a control from the second list, converts the touch coordinate value into a touch event, and sets the control ID of the control to obtain a focus so that the control receives the touch event. When the control accepts the touch event, the control enters a new window to execute the touch event. The processing module 114 waits for the new window to exit (e.g., the touch event is completed or the user manually closes the new window), and returns to the original window (i.e., returns to the window before the new window is displayed). It should be noted that, when the processing module 114 reads the control ID and the touch coordinate value of one control from the second list, that is, the control is processed, the information of the control is deleted from the second list.
After returning to the original window, the processing module 114 determines whether there are any unprocessed controls in the second list. The processing module 114 may determine whether there are any unprocessed controls by determining whether the second list is empty. When the second list is empty, it indicates that all homogeneous controls have been processed. When the control ID and the touch coordinate value of the recorded control still exist in the second list, indicating that there is an unprocessed control, the processing module 114 continues to read the control ID and the touch coordinate value of the next control from the second list, so as to process the next control.
FIG. 3 is a flowchart of the method of the present invention according to a preferred embodiment of the information searching method. It should be understood that the information searching method of the present invention is not limited to the steps and sequence shown in the flowchart of fig. 3. Steps in the flowchart shown in fig. 3 may be added, removed, or changed in order, according to various embodiments.
In step S301, the monitoring module 110 monitors the touch event on the touch screen 10 and identifies an operation of the touch event on the touch screen 10, for example, whether the operation is a multi-touch operation. In the preferred embodiment, the monitoring module 110 creates a container view (ContainerView) for intercepting and listening to touch events, the container view is started up when the electronic device 1 is powered on, and other applications are included in the container view after being started up. When the user touches the touch screen 10 with a finger, the container view first monitors for a touch (touch) event. The container view intercepts the touch event and does not distribute (dispatch) the touch event to the controls of the top-level window currently displayed by the electronic apparatus 1.
It should be noted that a single touch of a finger on the touch screen 10 may trigger the ACTION of ACTION _ DOWN first, or immediately after the ACTION _ MOVE, and then trigger the ACTION _ UP after the finger is lifted, and each touch may include the above-mentioned series of ACTIONs. The monitoring module 110 obtains touch coordinates of one or more touches included in the touch event, stores touch coordinate values of a series of ACTIONs of the one or more touches in a group of data structures corresponding to the touches, and identifies whether the touch event is a single-point touch or a multi-point touch by analyzing coordinate values when the ACTION _ DOWN and the ACTION _ UP are triggered in the touch event. If there are multiple different X, Y values when the ACTIONs of ACTION _ DOWN and ACTION _ UP are triggered, the monitoring module 110 identifies the touch event as a multi-touch operation, otherwise, identifies the touch event as a single-touch operation.
In step S301, when the touch event is identified as a multi-touch operation, the recording module 111 records information of the touch event in a first list. In the preferred embodiment, the recording module 111 sequentially records coordinate values of the touch screen 10 operated by the multiple touches included in the touch event in the first list. It should be noted that, when the touch event is identified as a single-touch operation, the recording module 111 does not perform operations such as recording, and the processor 12 assigns the touch event to a specific control in the currently displayed top-level view of the electronic apparatus 1 in the view container for processing.
In step S302, the parsing module 112 parses the information of the touch event recorded in the first list to obtain a plurality of controls triggered by the touch event, and obtains parameters of the plurality of controls. In the preferred embodiment, the parsing module 112 determines the trigger range of each control in the top-level window currently displayed by the electronic device 1 by obtaining the screen coordinates of all the controls in the top-level window currently displayed, and compares the coordinate values of the multi-touch operation recorded in the first list with the determined trigger range of each control to determine the plurality of controls triggered by the touch event. In the preferred embodiment, the parsing module 112 may obtain the screen coordinates of each control by first obtaining the window coordinates of the top-level window currently displayed by the electronic device 1, then obtaining all the controls in the top-level window and obtaining the layout coordinates of each control, and using the window coordinates of the top-level window and the layout coordinates of each control. The parameters of the control may include, but are not limited to, a control ID, a class name, touch coordinate values, and the like of the control.
In step S303, the determining module 113 determines whether there is a similar control in the plurality of controls according to the acquired parameters of the plurality of controls. In this preferred embodiment, the determining module 113 determines that there is a similar control in the plurality of controls by comparing the class names of the plurality of controls, and when two or more of the plurality of controls have the same class name, the determining module 113 proceeds to step S304. It should be noted that, when the determining module 113 determines that there is no similar control in the plurality of controls, the process is ended, the processor 12 assigns the touch event to the current display top view of the electronic device 1 in the view container, and the electronic device 1 processes the control according to the original processing method.
In step S304, the processing module 114 records the determined control IDs and touch coordinate values of the similar controls in a second list, and sequentially processes the controls in the second list.
Referring to fig. 4, it is a detailed flowchart of the step S304 in the information searching method according to the present invention. It should be understood that the information searching method of the present invention is not limited to the steps and sequence shown in the flowchart of fig. 4.
In step S401, the processing module 114 sequentially obtains a control ID and a touch coordinate value of a control from the second list, and converts the touch coordinate value into a touch event. It should be noted that, when the processing module 114 reads the control ID and the touch coordinate value of one control from the second list, that is, the control is processed, the information of the control is deleted from the second list.
In step S402, the processing module 114 sets the obtained control ID of the control to obtain a focus, so that the control accepts the touch event, and enters a new window to execute the touch event.
In step S403, the processing module 114 determines whether the new window exits and returns to the original window, i.e., returns to the window before displaying the new window. When the new window exits and returns to the original window, the process proceeds to step S404. If the new window is not exited, the processing module 114 continues to wait and determines whether the new window is exited. It should be noted that if the exit module 114 waits for a preset timeout period, the new window is not exited yet, and the process ends directly.
In step S404, the processing module 114 determines whether there are any unprocessed controls in the second list. The processing module 114 may determine whether there are any unprocessed controls by determining whether the second list is empty. And when the second list is empty, all the similar controls are processed, and the process is ended. When the control ID and the touch coordinate value of the recorded control still exist in the second list, it indicates that there is an unprocessed control, and the process returns to step S401 to continue reading the control ID and the touch coordinate value of the next control from the second list, so as to process the next control.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the above preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
