Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
For the operating environment compatible with Android running on the Linux operating system, the Android operating environment runs in a container.
Fig. 1 is a Linux-Android-compatible simulated two-finger scaling method provided in an embodiment of the present invention, which is applied in an operating environment where Android is compatible to run on Linux, and includes the following steps:
step S1: executing an action simulating the scaling of the two fingers on the Android application window, and detecting and analyzing a message simulating the action simulating the scaling of the two fingers by the Android application window; the actions include: pressing or releasing a keyboard key, pressing or releasing a left key and a right key of a mouse, moving the mouse and rolling a mouse roller;
for example, when an Android application window executes an action of simulating two-finger zooming, a crtl key of a keyboard can be pressed, and a mouse is dragged to move back and forth; or press the crtl button in the keyboard and scroll the mouse wheel up and down.
And pressing a crtl key on a keyboard under a certain Android application window. And the Android application window detects a pressing event of the crtl key. The Android application window is a window program realized through QT, and is mainly realized through QSinow class and QWidget class of QT.
For both the QWindow and QWidget classes, a key press event, i.e., void key press event (QKeyEvent) override, can be obtained by rewriting the keypress event function; the keyPresssevent function can acquire key press event messages of QBindow and QWidget, wherein the pressed key value can be read through event- > key (), so that whether the key is a ctrl key or not is judged.
For both the QSinow and QWidget classes, mouse press and release events can be captured by rewriting the mousePresEvent and mouseReleaseEvent functions, i.e., the mouse press and release events
void mousePressEvent(QKeyEvent*event)override；
void mouseReleaseEvent(QKeyEvent*event)override；
The mousedepressevent function can acquire mouse-down event messages of QWindow and QWidget, and the mouseReleaseevent function can acquire mouse-up event messages of QWindow and QWidget, wherein coordinate values of mouse-down or mouse-down can be read through event- > x () and event- > y ().
For both the QWindow and QWidget classes, mouse wheel scroll events can be obtained by rewriting the wheelEvent function, i.e., the
void wheelEvent(QWheelEvent*event)override；
The mousePressEvent function can acquire mouse wheel scroll event messages of QWindow and QWidget, wherein the vertical y coordinate distance of the mouse wheel scroll can be read through event- > delta (), the value of which is greater than 0 represents downward scroll, and the value of which is less than 0 represents upward scroll.
Step S2: the Android application window distributes a message simulating the action of scaling of the two fingers to equipment nodes under a dev/input directory of a Linux side through a socket;
step S3: a system input event reading component on the Android side reads data in a device node under a dev/input directory, and notifies a system input event processing component on the Android side of the read input event message;
the Android-side system input event reading component eventhb can continuously read data in the device nodes/dev/input/event 0,/dev/input/event 1,/dev/input/event 2, and can read keyboard key pressing events, mouse pressing and moving events and mouse wheel rolling events.
Step S4: the Android-side system input event processing component analyzes an input event, judges whether the input event meets a set simulation double-finger event rule, generates a double-finger event according to the rule if the input event meets the set simulation double-finger event rule, and converts and encapsulates data originally describing the input event into double-finger touch event data;
in particular, the amount of the solvent to be used,
the structure of the type of the original data read by the Android side input event reading component EventHub is as follows:
in the input _ event structure, a field type is a device type and comprises three types, namely a mouse, a keyboard and a touch;
the field code is an accessory attribute of type, a roller and a coordinate attribute exist in mouse operation, a key number attribute exists in a keyboard, and a coordinate attribute exists in touch;
the field value represents the value of the code attribute, which is added to the description below for three device data reports:
when the roller operates and reports, the value of the required attribute is obtained through input _ event- > code. input _ event- > code ═ REL _ WHEEL, which represents the roller attribute, at this time, input _ event- > value is to obtain the current roller direction, more than 0 represents downward scrolling, and less than 0 represents upward scrolling; if input _ event- > code is ═ ABS _ X, representing the X coordinate attribute, and at the moment, input _ event- > value is to obtain the X coordinate value; if input _ event- > code is equal to ABS _ Y, representing the Y coordinate attribute, and obtaining the Y coordinate value by input _ event- > value at the moment;
when a keyboard is operated, code is a corresponding key number, if input _ event- > code ═ 29 represents a ctrl key number, at this time, input _ event- > value can acquire a key pressing and lifting state, value ═ 1 represents pressing, and value ═ 0 represents lifting;
when there is a touch operation, if input _ event- > code is ═ ABS _ X, it represents an X coordinate attribute, and at this time, input _ event- > value is to obtain an X coordinate value; if input _ event- > code is equal to ABS _ Y, representing the Y coordinate attribute, at this time, input _ event- > value is to obtain the Y coordinate value.
The Android side input event processing component InputREADER converts and encapsulates original data into a MotionEvent data type of a touch event as follows:
in the MotionEvent data type, a field mdevice id represents a device identifier, mdevice id ═ 1 represents a keyboard event, mdevice id ═ 2 represents a mouse event, mdevice id ═ 3 represents a touch event, since a touch event is simulated, mdevice id should be equal to 3 in this case;
the field mDisplayId represents the active window number of the current operation;
the field mAction represents three actions of pressing, sliding and lifting;
the field mdown time indicates the time when the current event occurs;
the field mPointerCoords stores the x, y coordinates of a touch point, and Vector is a set type, indicating that a touch point may be multiple.
Step S5: the Android side system input event processing component sends the converted and packaged double-finger touch event data to the Android side system input event distribution component; and the system input event distribution component on the Android side sends the received double-finger touch event data to the currently active Android application, distributes the simulated motion track through an interface, and executes zooming after the Android application monitors the event.
Further, before step S1, the method further includes:
and mounting the equipment under the Linux system/dev/input directory into the container, so that the Android system running in the container has the right to read the data of the equipment node under the Linux side/dev/input directory.

docker is a container technology that effectively partitions resources of a single operating system into isolated groups to better balance conflicting resource usage requirements among the isolated groups. In the Linux-compatible Android environment, the Android system runs in a docker container of a Linux end. The docker create command can create a docker container through a docker image, and the docker create-device ═ dev/input:/: rwm parameter can mount the device under the Linux system/dev/input directory into the docker container, so that the Android system running in the docker container has the right to read data in all device nodes under the Linux terminal/dev/input directory.
