Based on above-described embodiment and preferred embodiment, the whole flow process to illustrate scheme interacts, in this preferred embodiment
In, provide a kind of screen projective techniques, this method can be applied to mobile terminal, terminal or other can with it is aobvious
Show the equipment that equipment interacts.The screen projective techniques are illustrated below.
Terminal, which opens the screen projection function based on Miracast and screen is established between terminal and display equipment and is projected, leads to
Behind road, just the content of terminal screen is projected in display equipment when satisfaction starts projection condition；Equally, when satisfaction terminates to throw
Stop in the display equipment for projecting the content in terminal when penetrating condition.These conditions can be that terminal operating encounters certain in the process
Triggering screen projects during preset condition a bit or user is triggered by clicking icon.
For the above, need to realize following key method：
Method one：The opening and closing screen projection function of terminal intelligent, preset opening and closing screen are thrown in the terminal
The condition penetrated just automatically turns on or closes when the condition is satisfied screen projection function.
While screen projection function channel being established between terminal and display equipment, preset opening and closing screen projection
The condition of function, for example, open screen projection function condition can be：The attribute for the control that user clicks is broadcast for " play " etc.
Put control property；For example the condition of closing screen projection function can be：At the end of the video playing played.
Specifically, after the screen projection Path Setup between terminal and display equipment, terminal monitoring module is begun to
The action of each operation of the user on terminal interface is monitored, if monitoring the action and preset opening and closing screen
Projection is kept strokes, then the instruction for being turned on or off screen projection just is sent to display by the channel that screen projects
Equipment, the content that the post analysis that display equipment receives receives is control instruction or data transfer instruction, if control
Instruction, just responds the control instruction, response results is sent to terminal, terminal performs unlatching after receiving response
It (terminal interface content mirrors are transferred to display equipment) or close and (stops terminal interface content mirrors being transferred to display and set
It is standby) screen projection action；If it is interface mirror image transferring content that display equipment, which receives content, display terminal just directly displays
The content；If terminal monitoring to user action and the preset action for being turned on or off screen projection it is inconsistent, that
Terminal monitoring module does not need to do any operation.
Method two：Terminal opens screen projection function, establishes terminal and shows the screen projection interface channel between equipment.
There is the icon that screen projects on terminal interface, user, which clicks the icon, can realize that the content since current interface projects
It shows in equipment, can also realize does not allow to project in display equipment by the content that current interface starts.
After establishing screen projection function channel between terminal and display equipment, there is screen to project work(on the screen of terminal
The small icon of energy, whether terminal monitoring user clicks screen projection icon, if user is to open screen in terminal " click " action
Curtain projection operation, terminal projects channel by the screen established between terminal and display equipment and sends control instruction, similary aobvious
Show that monitoring of tools terminal sends the type of content, receive the content that instruction post analysis is control instruction or transmission data, such as
Fruit is control instruction, and just the control instruction is responded, and the result of response is sent to terminal, terminal is just opened after receiving
Beginning mirror image transport interface content；If " click " action is to close screen projection operation, display equipment makes sound after receiving
Should, stop terminal interface and show on the display device.
The above method 1 and method 2 are illustrated with reference to concrete implementation scheme.
Method 1：
The module that method 1 is related to mainly has with lower module：Monitoring module, screen layout's extraction module in terminal, end
The comparison module in screen projection opening and closing condition presetting module (condition presetting module) and terminal on end, is tied below
Each module is closed to illustrate method 1.
1. the monitoring module in terminal：For monitoring the operational motion and operation object at active user place interface, monitoring
Form can be (action：Operation object), which includes action monitoring submodule and operation object generation submodule again
The current operational motion of monitoring user is responsible in block, action monitoring, including clicking, double-clicking, sliding；Operation object generates submodule
Operation object is determined according to the attribute of the control of user's operation.
Operation object refers to the control of user's operation, is unique in current interface, is in screen layout file
Control property obtain, here why not directly use " action：Control property ", the reason is that control property is not single
, on a screen of terminal, a control is unique, but attribute of the control in screen layout file but differs
Surely it is unique, it is sometimes necessary to determine the control object with multiple attributes to integrate, such as following examples 1.
Example 1：Terminal monitoring module monitors are to operation of the user on interface：It " clicks：
com.android.gallery3d:Id/gl_root_view (the resource ID property value of video play controls) ", the attribute of control
Value can be resource ID, description and text attributes, according to the property value (com.android.gallery3d of control:id/gl_
Root_view) object of control (video play controls) is got, the operation corresponding (action：Operation object) be：It is " single
It hits：Video play controls ".
How following examples 2 to obtain the object of control to illustrate according to the property value of control.
Example 2：The operation of user is " clicks：Lantern slide play control attribute ", operational motion is to click here, and lantern slide is broadcast
Putting control property is：(type, value), type are above-mentioned lantern slide play control attribute types, and value is control type
Value, type=text, value=Slideshow, action=click here.So utilize android
The api function that uiautomator is provided obtains control object, following code according to the word attribute of control：
{ UiObject mItem=new UiObject (new UiSelector () .text (Slideshow))；}
//mItem is that control word plays corresponding object for lantern slide
2. screen layout's extraction module：The corresponding topology file of screen describes some letters of the control in the screen
Breath, including information such as the corresponding class name of control, packet name, coordinate, resource ID, text attributes, descriptions.Topology file extraction module comes
Complete the extraction of the topology file of cloth screen.The extraction of topology file can be used in android SDK
Uiautomatorviewer.bat is obtained.
3. the screen projection opening and closing condition presetting module in terminal：The Path Setup success that terminal is projected in screen
Later, prompting user preset screen projection opening and closing condition, the form of condition is " action：Operation object ".
The foundation of preset condition can show some scenes after user establishes screen projection channel to user, and user is at this
It is operated in scene, " the action of operation：Operation object " will be registered as preset condition.Such as：Path Setup is projected in screen
After success, the scene of displaying can be the startup broadcasting in video player, and user is prompted to will click on broadcast button setting
For preset condition.
Condition presetting module can also dynamically increase during screen projects, and user can be to a control object
It is preset condition by the action mark after operation.
One group of preset condition occurs in groups, including opening and closing condition, means, if the operation that user is current
Meet the unlatching screen projection condition in certain group preset condition, then, the condition for terminating screen also must be in this group of condition.Only
New stack screen projection preset condition could be opened after there are the default opening and closing currently organized.If for example, pass through
Unlatching screen projection condition in certain group (for example, A groups) preset condition opens screen projection, then, only pass through the closing of A groups
Screen projection condition, which could close, terminates screen projection.
As a kind of optional scheme, the unlatching screen in different groups of preset conditions can also be passed through according to scene needs
Curtain projection condition and closing screen projection condition, carry out the beginning and closing of screen projection.For example, by A group preset conditions
Unlatching screen projection condition open screen projection, can pass through the closing screen in B group preset conditions project condition close shield
Curtain projection.Under this scene, although the control of screen projection is more flexible, there are unstable to ask for screen projection control
Topic.Which kind of mode screen projection control is carried out especially by, can be set according to actual needs.Said display projects pre-
If condition can be as shown in table 1, it should be noted that following opening and closing refer to the opening and closing of screen projection.
Table 1：The preset condition table of screen projection
4. the comparison module in terminal：User often operates a step on terminal interface, and the monitoring module 2 in terminal is to monitoring
Operation (the action of the user arrived：Operation object) and presetting module in content be compared.Such as one control of user click,
The action in the control property and preset condition in topology file and control property comparison are extracted, if unanimously, being carried out presetting
Corresponding unlatching screen projection operation, extracts the corresponding condition for closing screen projection of this group of preset condition, such as at this time in condition
It is consistent with the value for presetting closing screen projecting space that fruit monitors control property value, is carried out closing screen projection function.
The module that method 2 is related to mainly has with lower module：The instruction sending module of monitoring module, terminal in terminal,
Monitoring module on the mirror image data sending module of terminal and display equipment, says method 1 with reference to each module
It is bright.
1. the monitoring module in terminal：Screen projection icon whether is clicked for monitoring user and is turned on or off screen
Projection function calls end command sending module if user clicks the icon.
2. the instruction sending module of terminal：Monitoring module is monitored into content and is sent to display equipment.To in every frame data
Flag is added to represent that the content of frame transmission is control instruction.
Specifically, data are transmitted in the form of " frame ", will be filled using Real-time Transport Protocol based on the transmission of Miracast
Position is set as " 1 ", the tail portion of the message fill 8 hytes, with this 8 for group come represent transmission control instruction class
The content of type and control instruction is set as " 0 " to represent being control instruction by the 1st, and 7 below represent the interior of control instructions
Hold, the content of instruction includes opening screen projection and closes screen projection, is also easier to be represented with 7 bits.
3. the mirror image data sending module of terminal：The mirrored content at terminal device interface is sent to display equipment.
Specifically, data are transmitted in the form of " frame ", will be filled using Real-time Transport Protocol based on the transmission of Miracast
The content that position is set as " 0 " or filler is " 1 " but the first place of 8 of message tail is " 1 ", and representing the content of the frame is
Mirror image data content.
