MORE & MAML Overview MAML engine scripting language MIUI Application Markup Language for MORE (MIUI MORE engine application markup language)

MORE rendering engine Markup Oriented Rendering Engine (the rendering engine based markup language)

Outline Initially Variety lock screen for use with a specific syntax description xml lock screen. Later continuous enhancements, and gradually evolved into a near universal interface description language and graphics rendering engine, at a certain demand for developing user interface styles. Can be easily changed by replacing the skin interface style, animation or interactive mode. MAML Android interface description language and similar xml. The difference is that Android is a static interface description, changes to the interface elements depend java code. MAML describe static interface + dynamic attributes, UI timeline constantly refreshed by a certain frame rate, UI updated in real time based on the calculation results show variable expression of element attributes. MAML language and runtime engines have been independent from the lock screen as MIUI built into a common framework, in addition to displaying the date and time, but also supports the query criteria Content Provider to obtain a variety of information such as weather. Display pictures of various elements such as text, a variety of animations, slide interactive interface controls such as clicking, suitable for implementing the present information or simple interaction interface. Such as clocks, weather widget, alarm clock ringing interface. Framework supports dynamic frame rate, according to a fixed frame rate does not have to stop rendering, animation and updated without stopping at the right time rendering, only this time with minimal resources, for slowly changing animation rendering using a low frame rate, high dynamic animation begins Immediately after the adjustment to render high frame rate at full speed. The basic frame rate at full speed in full screen rendering can reach 60. Rational use can both cool and not much power.

MAML Variety lock screen application in Variety lock screen theme lockscreen bag / directory under the advance, manifest.xml file is described in the script ...

frameRate: Specifies the frame rate, if the animation is slow, you can specify the value of smaller, energy saving. The default is 30. displayDesktop: The default is false, perspective to the desktop features, if there is no lock screen wallpaper or lock screen wallpaper can be removed or transparent can see the desktop or the application launcher in front of the lock screen. You can achieve the perfect WP7, Meego, Ali cloud and other unlock interface. showSysWallpaper: The default is false, whether to display the lock screen wallpaper. If you do not specify after opening the lock screen wallpaper , will be used as a lock screen wallpaper wallpaper. screenWidth: set the screen width criteria. If specified as 720, the location of all the elements of the lock screen layouts are written by 720p, 480p phone will automatically scaled.

MAML applications dynamically changeable wallpaper and icons Variety Wallpaper Variety wallpaper in the theme package miwallpaper catalog description file is manifest.xml. Consistent with the root node represents Variety lock screen:

...

width: width represents amazing wallpaper. height: represents the height Also, if you want to achieve the effect of finger sliding elements follow, need the help of # wallpaper_offset_pixel_x, # wallpaper_offset_x wallpaper_offset_pixel_x: the number of pixels offset (0 to -1 * screen width) wallpaper_offset_x: Offset percentage (0 to 1.0) Relationship between the two: #wallpaper_offset_x * screen width = -1 * # wallpaper_offset_pixel_x Slide: In the first screen, wallpaper_offset_pixel_x = 0, wallpaper_offset_x = 0; slid the last screen, wallpaper_offset_pixel_x = -1 * screen width, wallpaper_offset_x = 1.0 To adapt to different resolution models, we recommend using #wallpaper_offset_x. The proposed design approach: 1. Wallpaper cut dual wide (screen width refers screenWidth) 2. Wallpaper position: x = "- # wallpaper_offset_x * screen width" 3. Need to follow the sliding element positioning: x = "- # wallpaper_offset_x * Wide screen wallpaper + relative position"

Dynamic Icon Under the theme of dynamic icons pack icons \ fancy_icons \ directory, each dynamic icon is a folder, the folder name is the corresponding app package name. For example, the icon is a dynamic calendar called "com.android.calendar" folder, which contains the description file manifest.xml ...

hideApplicationMessage: default false, shielded notice the top right corner flag. useVariableUpdater: Which system variable specifies the need, now includes power and time, and you can specify the update period of time, if the time gadgets updated every second, you need to specify the update cycle for one second, otherwise a default will be updated every minute. If a gadget or a dynamic icon display only the date is updated once a day, you can specify the update cycle for one day. Try to choose a longer update cycle, in order to save system resources.

Currently supported tag: Battery, DateTime.Day, DateTime.Hour, DateTime.Minute, DateTime.Second If a gadget does not require electricity or time variable, you need to use useVariableUpdater = "none", specifies the time variable and so do the update. If a gadget display system power and change per hour depending on the time display background images: useVariableUpdater = "Battery, DateTime.Hour" If you need to refresh several times per second, and can be used directly frameRate

Wallpaper element Wallpaper wallpaper element reference can not specify the source images and properties can be controlled. Without can be multiple. Examples:
system settings, in addition to other things you Image elements identical, animations, and other this element does not display wallpaper. There />

Variable variable name variable name expression corresponding variable or constant expression Note: If you define a string constant need more single quotes: expression = "'my string'" type = number / string variable or a string variable to define default values: number const = true variable is calculated only once at initialization time, he would not be recalculated, can improve efficiency. If the variable value will change during the lock-screen operation, const set to false Default: false threshold threshold trigger, when the change variable value exceeds the set threshold, can trigger some commands. For example:

The code represents the value of # time3 every change of 1, it will execute all commands inside persist default false, variable persistence. After designated ture, if not re given the value of the other variable, then the value would have been saved,

after re-lock or unlock regardless reapply themes are not restored

Variable array variable array ... ...

Item array element definition expression elements corresponding expression If the element is a constant value, the value is specified by a constant value // Define a two-second rotation time date display format DateTime every element. // Array elements can be used to display different values ​ based on numeric variables string <-! If const is true, the variable will only evaluate once at the initial time, ->

// Display the English Month = "February" /> = "November" /> = "December" /> month_str" color = "# FFFFFFFF" size = "20" ... />

Text Displays the format of the text, the coordinates attribute support variables color: text color, # FFFFFF size: Text Size format: If you need to display a variable number in the text, you need to specify the format, specify the numeric position with% d paras: If you specify the format, you need to specify the corresponding variable expression% d in paras where there can be multiple expressions with variables, "" separated align: alignment of the left, center, right, text coordinates textExp: literal expression, you can directly call the desired output variables such as "time is now 9:00," can be written textExp = "'Now the time is' + # hour12 + 'point'." width text width, when the text exceeds the specified width will be cut off. If the multi-line specifies the display will fold lines. If you specify the text scrolling, scrolling in the specified location will display text marqueeSpeed ​ text scrolling speed, with the width of the use of the above marqueeGap scroll interval. When the interval after the re-emergence of the text display, the default width of four characters rotation (X, Y, Z) rotation angle, the old angle can also be used, but the recommended rotation, because of relatively high atmospheric internationalization multiLine ture / false whether to support multi-line display, default false

spacingMult multiple default spacing 1 increase the amount of the default spacing spacingAdd 0 text.text_width width of a line of text that can be used to typeset # Tt.text_width

Examples of usage: Display the next alarm time

textExp property supports string expression: * Weather information is displayed if the temperature is empty - not empty display values
Time

src time picture of the prefix follows that the use time_0.png, time_1.png, ... time_9.png, time_dot.png. Coordinate property supports variable expression space represents a gap time of the picture, we can use this feature to typeset time images, the use of positive images spacing becomes larger, then you can cut small pictures, save memory. For the projection of images, will write negative space, you can make a projection overlap to save space

Date Display format specified date format: Supports standard date format, an additional Lunar: NNNN

September: M -> 9 MM -> 09 7 minutes:

m -> 7 mm -> 07 mmm -> 007 mmmm -> 0007 1970 年 4 月 6 日 3:23 am "Yyyy / MM / dd h: MMAA" -> "1970/04/06 3:23 am" "M dated May d h: mmaa" -> "4月6日3:23 am" Week "E" -> "Wednesday" "EEEE" -> "Wednesday" "Day: M / d" -> "Day: 4/6" 24 hours: "kk: mm" -> "13:34"

Picture Pictures component used to display an image on the lock screen, you can specify various attributes

x, y coordinates relative to the upper left corner of the screen w, h width and height pivotX, pivotY center of rotation rotation angle of rotation, a week 360 src Image Name srcid picture sequence suffix number, usually with variable, you can display different pictures based on variables, if src = "pic.png" srcid = "1" will show the last picture "pic_1.png" 0-255 alpha transparency, less than or equal to 0 is not displayed antiAlias ​ true / false anti-aliasing, if true picture does not have serrated deformation in the rotation, but the speed will be slower srcExp picture source expression srcFormat picture source format srcForamtExp picture source format expression srcParas picture source parameters align / alignV alignment, have been introduced earlier.

Examples:

...

// SrcExp: Picture source expression

Digital Pictures

numeric expression number is to be displayed src is the file name of the picture source, support SourceAnimation If the src = "number.png" number_0.png number_1.png ... will be used to draw the digital image files. Time similar parts

Pictures mask

x, y coordinates src mask image, the black part represents an opaque opaque, the other part is transparent. align coordinates are relative or absolute position of the picture belongs, if it is relative, Pictures Mobile is moving mask will follow accordingly. Otherwise mask remain intact. Mask can also be active animation, rotation animation, animation and location, property supports variable expression

Elements of animation

All elements supports animated movie is divided into: Picture source, position, size, rotation, transparency, independent of each animation, each loop, the animation consists of several key frames, keyframes, including property and time frame, the picture outside source animation division, Other animation will find two adjacent key frames based on the current time, and then calculate the current linear interpolation property. If the first frame of the time does not start from zero, the default time is 0, the first frame as a picture of the original property, the time in milliseconds. Position in the animation position coordinates relative to the picture itself.







Example: Location animated representation of one second from the left to the far right of the screen, stay one second, transparency, transparency of 175 indicates the beginning of the animation, from the far left to the far right of the transparency of the process of change, after 0.5 seconds to reach the rightmost gradient opaque, 0.5 seconds and then disappear becomes transparent. Then loop.

NOTE: Only image support image source animation image source animation slightly different, no interpolation, x, y optional, represent the relative location of the picture, the current picture is found in the first list that is greater than the current time point specified



Group

Group is a group of meaning, equivalent controls are a container that can be used to contain live other elements, such as pictures, time, etc. By adding the group to coordinate and width and height, you can easily adjust the position and size of a onetime multiple elements. While Group also add a variety of animation types and Image as comprehensive The new version also adds a frame rate control, if a group of elements are static, you can add framaRate = "0", the system will automatically adjust the refresh rate, reduce memory and cpu usage each group based on the current frame rate. So it is recommended that you pick plus the corresponding frame rate when you add a Group

Slider

name: the name used for the variable name bounceInitSpeed, bounceAccelation rebound animation initial velocity and acceleration (distance in pixels, the time in seconds), all support the expression alwaysShow = "true / false" default is false, when a Slider visible, other Slider disappear. You can have any number of Slider components. Trigger Slider state switching, support the Trigger Slider starting point: the starting point of the elements contained in drag to move the position will follow the current operation.

// When switching from other states to NormalState, trigger the Trigger // When switching from other states to PressedState, trigger the Trigger // When switching from other states to ReachedState, triggered Trigger ->

Three state can not specify the variables can be used to change the status of the other interface elements to represent the triggering process. Slider target point: When the starting point x, y point fall EndPoint rectangle target area, reaching the trigger position, then release your finger that can generate a trigger, you can have more than one trigger purposes.

<-! Show the target position if pressed trying to unlock -> <-! Show specified image when reached target, if touch up then perform unlock -> <- Slider path

of tolerance:! After the start trigger action path when moving the maximum distance exceeds this value will be canceled = "" tolerance = ""> = "" y = "" /> = "" y = "" />

Examples:



Slider's intent may be a Trigger and Command, a Trigger can have multiple Command. See Command Trigger and Trigger & Command Unlocker inherit Slider, more than just the tag name usage Slider to Unlocker. unlocking member rebound animation, see http://www.miui.com/thread-290094-1-1.html Lock screen sounds StartPoint: normalSound, pressedSound, specified in the normal state and press play sound EndPoint: reachedSound, after reaching the endpoint play sound

Push button Button element can be used to receive clicks, double-clicking the event, and according to the definition of trigger to control other elements on the interface. Button element can also be passed to other elements on the event interface, to make the other elements in response to user actions on the lock screen interface.

All elements of the name attribute increases, the control object button specified by name. x, y, w, h specifies the button area. The button's event listener to specify which element to pass. Button can have a number of trigger, trigger defines the button action trigger-related operations, such as controlling the properties of an element

action: button action: down (pressed), up (lift), double (double-click) target: the name of the control objectives property: property name, currently supports: visibility will add other attributes to control later. value: property value for the boolean currently have: true, false, toggle Usually target button control has three categories, namely, visibility control, play animations, and execute commands, simple demonstration:

About command will be described in detail later in Button xml structure elements: ... ...

Music Player Specify the name, so that the display can be controlled by another button or not, such as double-click. Must contain 4 Button and a Text, and the name was specified name. May contain any other interface elements, such as Image like. autoShow true / false if they go into the lock screen when playing music, whether to automatically display MusicControl music_state stop a player playing status 0 After updating the music player supports the song and artist name displayed separately, respectively, using @ music_control.title and @ music_control.artist



Example: Double-click Show hidden control music control

Content Provider content provider support where the format: where = "" whereFormat = "" whereParas = "" content Provider support dependencies, ie after the end of a ContentProviderBinder query to get the variable as a parameter to the next query ContentProviderBinder triggers name1 name2 inquiry after inquiry ended, name1 name2 queries can use variables. And if the data changes name2 re-query, it will

content provider provides application information generic query interface that defines a new xml code to query the content provider, and queries to the binding information to the variables used to display information about third-party applications, as long as third-party applications to provide the appropriate The content provider. For example, you can display weather information, e-mail, to-do, notes, etc., you can also write an application to query any information you want and by content provider to provide to use the lock screen.

Trigger & Command Command Basic commands, the interface can be controlled through the properties of other elements in the object name and object. Usually controls the visibility (visibility) and animation elements (animation).

1. iamge1 is the name of the object to be controlled ".", followed by the property (currently supports visibility and animation). 2. Control when visibility, value which is written true or false, control the animation time, value write-play (currently not supported so that the animation pause) 3. condition is conditional, support for regular expressions. When the condition

where the condition is true, execute the command; is false, not executed. 4. delay is the delay, in milliseconds. After reading a delay before the command execution 5. delayCondition judgment is delayed, after the delay time and then judge. Examples: // Second <40, 2000ms delay execution

delayCond1 + 5" delayCondition = "lt (# second, 40)" delay = "6000" / second <40, executed delayCond2 + 5" condition = "lt (# second, 40)" delayCondition = "lt

VariableCommand Variables command, used to control variables (Var) value. Including the name and expression of two special attributes, condition, delay, delayCondition usage is consistent with Command // The width value assigned to the screen w

SoundCommand Voice commands can be used to play audio files

1. 2. 3. 4.

sound: the sound file name volume: loudness, a floating-point number between 0 and 1 loop: if looping, true / false, default is false. keepCur: when you play this audio, whether to keep the currently playing sound, true / false, default false.

Note: The sound file size requirements do not exceed 500kB, when the length is not more than 10 seconds (10 seconds after playback sound does not come out). Examples: // Loop reached.mp3, while constantly being played out other sounds

ExternCommand

Common commands used to send commands to external programs

At present, a command can be used is the unlock command (only valid in the lock screen)

Use this command to achieve the unlock operation, without the use of ExternalCommand And ExternCommand relative, is to receive an external command command, typical usage: in the lock screen, usually used to receive the opening screen / off-screen commands to execute some commands; desktop plug-in, is used to detect the cut screen to perform command resume indicates that the command executed when the opening screen, pause indicates that the command is executed when off-screen

Example desktop plug-cut screen use

Use the buttons to achieve switch

Bluetooth value = "on" value = "off"

Data

Ringtone / mute / shock

<-! Value = "normal, silent, vibrate" value = "silent" value = "normal"
In a comma-separated state key switch, you can specify only one state, each with a different multiple button state value value, you Three states switched Below and above the same effect Only normal and mute switch Only normal and vibration switch Only switch to mute other button to switch to another state

USB storage toggle / on / off

Wifi toggle / on / off

A sliding manner to achieve the switching

State variables, only add the appropriate command after the effective #ring_mode: 0 silent, 1 vibrate, 2 normal #wifi_state: 0 disabled, 1 enabled, 2 problem, 3 half (intermediate) #bluetooth_state: 0 off, 1 on, 2 half #data_state: 0 off, 1 on #usb_mode: 0 disconnected, 1 charge only, 2 storage, 3 intermediate Trigger's Command support variable assignment name: variable name, expression: assignment expression

Command Support Trigger animation playback controls



Dynamic Frame Rate Simple Usage In addition to the original frame rate frameRate property controls ordinary state, it also supports were set charging, the battery is low, full frame rate power state to facilitate the control of the frame rate under these conditions, to achieve energy saving goals. For example, there is no ordinary state animation frame rate can be set to 0, the charged state of animation, the frame rate can be set to 30, to show the smooth animation, such ordinary state can be very efficient. For example: frameRateCharging = "30" frameRateBatteryLow = "20" frameRateBatteryFull = "1"

Advanced Usage

To specify the xml description language different frame rates depending on the time line, add an element, called FramerateController, the same elements, and other interface elements can be added to each container, this element contains a frame rate control timeline specified in the certain amount of time to use a certain frame rate.

This element will control the frame rate at which it is under the timeline container, ie, frame rate change elements of the container under all animations are synchronized with this element specified.

Sensor calls Added You can bind the sensor data to the variables for gravity sensing, orientation sensor, acceleration sensors, pressure sensors (altitude) // Orientation sensor: type = "orientation" index = 0: azimuth, 0 ~ 359,0 = North, 90 = East, 180 = South, 270 = West index = 1: pitch angle, -180 ~ 180, z-axis to the positive y-axis direction of the steering index = 2: roll angle, -90 ~ 90, x-axis turning positive z-axis direction // Linear acceleration type = "linear_acceleration" index = 0: x direction of linear acceleration index = 1: linear acceleration in the y direction index = 2: z direction of linear acceleration Linear acceleration is to remove the influence of gravity: gravitational acceleration = linear acceleration + // Acceleration type = "accelerometer" index = 0: acceleration in the x direction index = 1: acceleration in the y direction index = 2: z direction acceleration // Gravity sensor type = "gravity" index = 0: gravitational acceleration in the x direction gravitational acceleration in the y direction: index = 1 index = 2: gravitational acceleration in the z direction // Pressure Sensors type = "pressure"

index = 0: barometric pressure units hPa. The average air pressure at sea level is 1013.25hPa, can be estimated based on t
