Detailed Description
Please refer to fig. 1. The invention provides a multi-screen display method which is applied to terminal equipment and comprises the following steps:
s1, displaying the multifunctional interface on an expansion screen;
and S2, receiving touch operation instructions on the main screen and/or the expansion screen, and finishing preset operation according to the touch operation instructions.
Specifically, the multi-screen display method comprises two parts of multifunctional different-screen display and multi-screen interface operation; wherein,
the multifunctional different-screen display is that a multifunctional interface is displayed on an expansion screen in a mode of adding View on Presentation by taking the Presentation as a carrier;
the multi-screen interface operation comprises two parts of knob key operation and Touch operation. The knob key operation is to use a knob key as the left and right direction keys of the remote controller. Touch operation is common operation of a user, such as clicking, long pressing, sliding operation and the like. The response operation is performed by different modules operated by the user.
Further, since not all interfaces of the application are structured left and right, for example: some lists need to be slid up and down.
In order to provide different interface operation options for different application program interfaces, the invention adopts a DispatchKeyEvent method to intercept key events, carries out event interception on a page needing to slide up and down, and can reserve legal touch operation and intercept illegal touch operation of a user under the current application program through event interception. For example: the method includes the steps of intercepting a KeyEvent of a LEFT key of KeyEvent, KEYCODE _ DPAD _ LEFT to a non-down event, customizing a KeyEvent of a key of KeyEvent, KEYCODE _ DPAD _ UP to be sent out through a discrete KeyEventFromInputmethod, and processing the right key.
Further, the specific implementation steps of the multifunctional different-screen display are as follows:
101. acquiring an expansion screen;
acquiring the number of connected screens through the DisplayManager, wherein the number is more than 1, which indicates that we can obtain the number of connected screens
An application expansion screen.
102. Then, performing multifunctional different-screen display;
the multifunctional different-screen display is characterized in that Presentation is used as a carrier, and the display is carried out on the carrier in an addView form.
101. Putting the added View into a List;
simulating an Activity stack, and simulating stack pushing and stack popping by using an addView and removeView method;
further, the specific implementation steps of the multi-screen interface operation method are as follows:
201. performing dispatchKeyEvent event processing;
in order to diversify the knob event, the interception of Key is performed in the dispatchKeyEvent event. The method comprises the steps of intercepting a KeyEvent from a KeyEvent, KEYCODE _ DPAD _ LEFT LEFT key KeyEvent in an interface needing to scroll UP and down, customizing a KeyEvent by a dispatch KeyEventFromInputmethod, sending the KeyEvent from a key-UP key, and processing the right key in the same way.
202. Carrying out onTouchEvent treatment;
the Touch event is a default Touch event handler of the android system, and event distribution is performed through processing of motionevent.
203. Different modules control different content;
please refer to fig. 5 and 6. Such as playing music, browsing files, audio settings, opening applications, etc.
The different modules are different function controls made by the application, and music can be played by clicking the music control module with a music list. Data is acquired through an interface, and various operations such as playing video music and the like are realized through the interface.
As shown in fig. 5, by acquiring the quantity information, it is determined whether to display an operable module, which is the multi-screen interface operating module 12. The operable module displays different preset styles in different application scenes, for example, a style for playing music when a music playing Application (APP) is used on the expansion screen, a style for playing video when a video playing Application (APP) is used on the expansion screen, a style for browsing files when the operating module is used on the expansion screen, and the like.
Different applications require personalized touch control interfaces, and the following explanation is continued by taking music playing as an example: when playing music, the functions of playing the previous song, playing the next song, playing the beginning or pausing and the like need to be realized, when the function requirements are distributed to the knob key and the touch key, the right key of the knob key can be used for representing the playing of the next song, the left key can be used for representing the playing of the previous song, the single click of the touch key can represent the playing beginning or pausing, the double click of the touch key can represent the playing ending, and the like.
It should be noted that different modules (e.g., an operable module for playing music, an operable module for playing video, etc.) acquire data through an interface and perform various operations. The interface refers to an interface program, and the interface program may be a unified interface program or an interface program separately set for each module.
Please refer to fig. 6. The multi-screen interface operation comprises the following steps: acquiring screen quantity information; judging whether the operable modules are displayed or not, and if the number of the screens is more than 1, displaying the operable modules; if the operable module needs to be displayed, the operable module is displayed, and then the operable module receives touch operation information; an application program (software interface) executes the touch operation instruction. The contents of fig. 5 and 6 are complementary to each other.
Please refer to fig. 2. The present invention also provides a terminal 10 including a main screen 20 and an extended screen 30.
Please continue to participate in fig. 3. Furthermore, the terminal comprises a different screen display module 11, and the different screen display module is used for displaying a first interface and a second interface on a main screen and an expanded screen; the terminal further comprises a multi-screen interface operation module 12, and the operation of the first interface and/or the second interface on the main screen and/or the expanded screen is realized through the multi-screen interface operation module.
Please refer to fig. 4. An example of operation is provided below:
assuming that the main screen 20 and the extended screen 30 of the terminal have a first interface 201 and a second interface 301, respectively, the first interface and the second interface may correspond to two applications, respectively, and the first interface and the second interface may be used to fill the screen or to select a ratio of occupying the screen. Assume that a button key 202 and a touch key 203, which are virtual touch keys, are also currently displayed in the middle upper area of the main screen as a first interface and the lower area of the main screen. And the terminal sends an operation command to the second interface according to the touch operation command, so that the second interface on the expanded screen is operated and controlled on the main screen through the knob key or the touch key. In fig. 4, a change of the second interface state is achieved by operating a knob key or a touch key so that the second interface 301 is changed to the changed second interface 302.
The present invention also provides a computer-readable storage medium storing one or more programs, which are executable by one or more processors to implement the steps of the multi-screen display method as described in any one of the above.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made in the above embodiments by those of ordinary skill in the art without departing from the principle and spirit of the present invention.
