- BUIW technology based on BREW can be responsible for UI construction.
- BUIW technology has two major features in UI construction: one is the concept of layer; the other is to provide the concept of customization. Among them, the customized mechanism allows manufacturers to design GUI controls themselves.
- the widget uses the framework of the model-view-controller (MVC). Specifically, when the model changes, the event is reported in time and passed to the event handler, which ultimately updates the appearance of the control.
- MVC model-view-controller
- the widget has: managing its own border and background style, the image text displayed thereon, receiving touch event information and key events occurring thereon, and also inserting a plurality of other child widgets, and assigning the display of the content to Sub-widget and other advantages.
- the invention provides an information bar display device based on the BUIW platform, as shown in FIG.
- the device includes: a database 11 of a doubly linked list, a model module 12, a widget module 13, and an arrangement algorithm module 14;
- a database 11 of a doubly linked list for storing data information of all domains related to the information bar;
- a model module 12 for all processing of data in the database 11 of the doubly linked list, and when the data in the database 11 of the doubly linked list changes Used to send changed data information to the widget module 13;
- the widget module 13 is configured to: after receiving the data information sent by the model module 12, partially or completely draw the display area of the information bar according to the received data information, and invoke the arrangement algorithm module when all the information bar display areas are drawn 14;
- the arrangement algorithm module 14 after receiving the call of the widget module 13, is used to divide the display area according to the existing display space, all the domains to be displayed, the domain priority, and the range occupied by each domain.
- the above device may further include:
- the touch screen controller 15 is configured to send the event including the click event, the coordinate of the event occurrence, and the corresponding area of the click area to the widget module 13;
- the widget module 13 is further configured to: after receiving the information sent by the touch screen controller 15, start the corresponding application module 16 according to the service-related logical event corresponding to the event clicked in the information;
- the application module 16 is used by the widget module 13 to process business related logical events. Based on the above device, the present invention implements an information bar display method based on the BUIW platform, as shown in FIG. 2, and includes the following steps:
- Step 201 When the data of the doubly linked list changes, the model sends the changed data information to the widget;
- the data of the doubly linked list includes: a domain number (ID), a domain priority, a state value priority, and a state value;
- the data structure of the doubly linked list is as shown in FIG. 3, including: a main linked list and a sub-linked list; a horizontal main list, which is indexed by a main node, and each main list is represented by a main node representing each domain.
- the priority of the domain is increased to the connection, where the domain ID and domain priority of each primary node are different.
- the domain ID can be used to know which domain, domain and domain ID can be set according to user needs. For example: The user currently sets three domains, including: phone domain, SMS domain, and battery domain. You can set the phone domain ID to phone field.
- the domain priority can be set according to the user's needs. For example, the user currently sets three domains, including: a phone domain, a short message domain, and a battery domain. If the user believes that the battery domain is the most important in all the domains set, the phone domain is second most important, and the SMS domain is of the least importance, you can set the domain priority of each domain in this way: The domain priority of the battery domain is set to 3, the phone domain The domain priority is set to 2, the domain priority of the SMS domain is set to 1; the main list in the doubly linked list structure indicates that the primary node of each domain is from left to right in the order of SMS domain, telephone domain, and battery domain. Connect right in the horizontal direction.
- the arrangement algorithm After all the fields in the main list are calculated by the arrangement algorithm, the position of each field on the display screen and the length and width of the display are determined. If the screen area is insufficient, some fields will be discarded according to the domain priority, and the domain with high priority will be displayed first. , the display area is full when it is displayed. Specifically, the arrangement algorithm divides the display area according to the display space of the screen, all the domains to be displayed, the domain priority, and the range occupied by each domain, and the domain with the highest domain priority is displayed on the screen according to the calculated display length and width.
- the domain priority is displayed, and all the fields are displayed when the display area is sufficient.
- the content displayed on the screen is determined by the status value of the main node. For example: When the status value of the telephone domain is set to 1, it corresponds to the picture of the missed videophone; when the status value is 2, the picture corresponding to the missed voice call ;
- the vertical is the sub-linked list, the sub-linked list and the main node have the corresponding relationship
- the linked list header of the sub-linked list is the main node
- the sub-linked list is all validly set by the user on the corresponding domain except the linked list header of the sub-linked list.
- different state values, and a collection of state value priorities, removed from the child list Outside the main node the sub-nodes are prioritized to the connection according to the state value of each sub-node.
- the newly inserted sub-nodes are closer to the list header, ie: Close to the main node.
- the priority value of the state value can be set to a minimum of 1, followed by 2, and the highest is 3; 1 indicates static display, 2 indicates flashing display, ie: the user is using the business function corresponding to the domain, and 3 indicates that multiple pictures are cyclically displayed.
- 1 and 2 are set in advance to the corresponding data of the child node when entering the service interface corresponding to the domain, and 3 are sub-nodes having different state values in the same sub-chain list, and are combined according to certain UI principles.
- the state value of the set telephone field is 1, it corresponds to the picture of the missed videophone; when the status value is 2, the picture corresponding to the missed voice call is
- the priority values of these sub-nodes are set to 3, while , start the loop timer, the duration of the loop timer can be set as needed, for example: 3s, within the loop timer timing range, showing the child node of the linked list head closest to the child linked list.
- the loop timer expires, the child node closest to the linked list header of the child linked list is deleted, and the deleted child node is inserted into the child linked list at the farthest end of the linked list header of the same state value priority ionic linked list.
- the data of the primary node and the child node includes: a domain ID, a domain priority, a state value priority, and a state value; wherein, in the same domain, the domain IDs and domain priorities of all nodes are the same;
- the state value priority of the node is equal to the maximum value of the priority value of the child node state value, the state value of the main node is the state value of the child node closest to the main node; the child node does not include the real time of the child node Status information, for example, for the phone domain, the status information of the child node in real time may be a missed video call, etc., and the data is stored in the application module corresponding to the domain. For the phone domain, the child node occurs in real time.
- the status information is saved in the phone module. Specifically, when the priority value of the primary node is 1, the state value of the child node closest to the primary node is the state value of the primary node; when the priority value of the primary node is 2, The state value of the child node closest to the head of the linked list is dominated State value of the node; When the priority value of the primary node is 3, the state value loop of all the child nodes whose priority value other than the primary node is 3 is taken as the state value of the primary node.
- the data of the doubly linked list is dynamically changed, and the model is responsible for all processing of the doubly linked list data, such as: updating the priority value and status value of the primary node status value, inserting the child node data, and the like.
- the model sends the changed data information to the widget, where: the model sends the updated data information indicating the domain ID, the domain priority, the state value priority, and the state value of the main node of the corresponding domain to the widget, and / or, model will add data information indicating the domain's primary node including domain ID, domain priority, status value priority, and status value to the widget.
- Step 202 The widget locally draws the display area of the information bar according to the received data information, or calls the arrangement algorithm to draw the display area of the information bar.
- the widget locally draws the display area of the information bar according to the received data information, or calls the arrangement algorithm to draw the display area of the information bar, specifically:
- the widget When the widget receives the updated data information indicating the domain ID, the domain priority, the state value priority, and the state value of the primary node of the corresponding domain, the widget has already saved the domain ID and domain priority of the domain. Level, at this time, the widget locally draws the display area of the information bar according to the received status value priority and the status value information, for example: replacing the picture corresponding to the status value;
- the widget When the widget receives data information indicating the domain ID, domain priority, status value priority, and status value of the primary node of the newly added domain, the widget receives the domain ID, domain priority, and status value according to the received domain ID.
- Priority, and status value information call the placement algorithm, according to the existing display space, all domains to be displayed, domain priority, and the range occupied by each domain, the display area is divided, that is: each domain is on the display Corresponding coordinates; and according to the result of the division, all display areas of the information bar.
- the method may further include: Step 401: The touch screen controller sends the event including the click event, the coordinate of the event occurrence, and the information of the corresponding area of the click area to the widget;
- the user can determine the click event through the touch screen controller, for example: the user can perform actions such as clicking, long pressing, dragging, etc., respectively, corresponding events can be: screen pressing, sliding, and releasing events;
- the generated coordinates and the information of the corresponding domain of the click area are sent to the widget; the information of the corresponding domain may include: a domain ID and the like.
- Step 402 After receiving the information, the widget starts the corresponding application module according to the service-related logical event corresponding to the event clicked in the information;
- the initiating the corresponding application module is an application module required to start a service-related logical event. For example, if the logical event belongs to a short message service, the short message module needs to be started, and the short message module is responsible for the logic of the short message. The handling of the event.
- the touch screen controller can include the event of viewing the missed videophone, the coordinates of the event, and the information of the telephone domain. Sent to the widget;
- the widget After receiving the information, the widget starts the phone module according to the service-related logical event corresponding to the event of viewing the missed videophone, and the phone module is responsible for displaying the missed videophone.
- the model processes the corresponding data in the doubly linked list, and sends the status value of the changed primary node to the widget, and the status value information is sent to the widget according to the received information. Re-draw the display area of the information bar.
- the implementation method is shown in Figure 5. It includes the following steps:
- Step 501 After the user uses the service interface corresponding to the child node, a new child node is generated, and the model determines whether the primary node of the domain corresponding to the new child node exists. If yes, step 502 is performed. Otherwise, step 503 is performed. ;
- the model determines whether the main node of the corresponding domain of the new child node exists, specifically: Whether the domain ID in the new sub-node is the same as the domain ID of the main node in the main list of the doubly linked list. If they are the same, the main node representing the corresponding domain of the new sub-node is considered to exist. Otherwise, it is considered to represent the new sub-knot. The primary node of the corresponding domain does not exist;
- the new child node After the user enters the service interface corresponding to the new child node, the new child node carries the domain ID, domain priority, status value priority, and status value information.
- Step 502 Insert the state value priority and the state value of the new child node into the child linked list of the primary node, and check whether all child nodes except the primary node in the child linked list can generate a new state. A combination of value precedence exists, if present, the state value priority of the associated child node that can generate the new state value priority combination is updated to a new value, and each child node is arranged in descending order of the state value priority, after which Step 504 is performed, otherwise, the current processing flow is ended;
- whether all the child nodes except the main node in the check sub-list have a combination that can generate a new state value priority specifically: checking the status of all child nodes except the main node in the sub-list Whether the values are the same, if they are the same, it is considered that there is no combination that can generate the priority of the new state value. If they are not the same, it is considered that there is a combination that can generate the priority of the new state value; if the newly inserted child node is capable of generating new

目前, 在 BREW的基础上新推出的 BUIW技术, 可以负责 UI的构建。 BUIW技术与 BREW技术相比,在 UI的构建上具有两大特色: 一个是阶层 ( layer ) 的观念; 另一个是提供定制化 (customize ) 的概念。 其中, 定制 化的机制允许厂商可以自行设计 GUI控件。
在 BUIW技术中 ,屏幕上各个元素由 widget来进行显示和控制。 widget 釆用模型-视图-控制器(MVC ) 的构架, 具体的讲, 当 model有变化时, 事件会及时上报并交给事件处理函数, 从而最终更新控件外观。 widget具 有: 管理自己的边框和背景样式、 显示在其上的图片文字等内容、 接收在 其上发生的触摸事件信息和按键事件、 以及还可以插入多个其他子 widget、 把内容的显示分派给子 widget等优点。
基于 BUIW平台的 widget控件的技术, 可以实现一种新型的、 动态的 信息条。
下面结合附图及具体实施例对本发明再作进一步详细的说明。
本发明提供了一种基于 BUIW平台的信息条显示装置, 如图 1所示,
该装置包括: 双向链表的数据库 11、 model模块 12、 widget模块 13、 以及 排布算法模块 14; 其中,
双向链表的数据库 11 , 用于保存信息条相关的所有域的数据信息; model模块 12, 用于负责双向链表的数据库 11中数据的所有处理, 并 在双向链表的数据库 11中数据发生变化时, 用于向 widget模块 13发送变 化的数据信息;
widget模块 13 , 用于在收到 model模块 12发送的数据信息后, 根据收 到的数据信息局部、 或全部绘制信息条的显示区域, 并在全部绘制信息条 显示区域时, 调用排布算法模块 14;
排布算法模块 14, 在收到 widget模块 13的调用后, 用于根据现有的 显示空间、 要显示的所有域、 域优先级、 以及每个域占据的范围, 划分显 示区域。
上述装置中, 还可以包括:
触摸屏控制器 15 , 用于将包括点击的事件、 事件发生的坐标、 以及点 击区域对应域的信息发送给 widget模块 13;
所述 widget模块 13 , 还用于在收到触摸屏控制器 15发送的信息后, 根据信息中点击的事件对应的业务相关的逻辑事件, 启动相应的应用模块 16;
应用模块 16, 用于被 widget模块 13启动, 处理业务相关的逻辑事件。 基于上述装置, 本发明实现基于 BUIW平台的信息条显示方法如图 2 所示, 包括以下步骤:
步骤 201 : 当双向链表的数据发生变化时, model向 widget发送变化的 数据信息;
这里, 所述双向链表的数据包括: 域编号(ID )、 域优先级、 状态值优 先级、 以及状态值;
所述双向链表的数据结构如图 3 所示, 包括: 主链表、 以及子链表; 横向的是主链表, 由主结点作为索引, 各主链表由表示每个域的主结点按 照每个域的优先级增向连接,其中,每个主结点的域 ID和域优先级均不同。 通过域 ID可以知道是哪个域, 域和域 ID可以依据用户需要进行设置, 比 如: 用户目前设置了三个域, 包括: 电话域、 短信域、 以及电池域, 可以 设置电话域 ID为 phone field, 设置电池域 ID为 battery field等等; 域优先 级可以根据用户的需求进行设置, 举个例子来说, 比如, 用户目前设置了 三个域, 包括: 电话域、 短信域、 以及电池域, 如果用户认为在设置的所 有域中, 电池域最为重要, 电话域其次重要, 短信域的重要性最低, 则可 以这样设置各个域的域优先级: 电池域的域优先级设为 3 , 电话域的域优先 级设为 2, 短信域的域优先级设为 1 ; 在双向链表结构中的主链表, 表示每 个域的主结点按照短信域、 电话域、 以及电池域的顺序从左到右横向连接。
主链表中的所有域利用排布算法计算后, 会确定每个域在显示屏上的 位置以及显示的长宽, 屏幕区域不够时会根据域优先级舍弃一些, 域优先 级高的域优先显示, 显示区域足够时要全部显示。 具体的讲, 排布算法根 据屏幕的显示空间、 要显示的所有域、 域优先级、 以及每个域占据的范围, 划分显示区域, 域优先级高的域按照计算出的显示长宽在屏幕上先排列, 排列的方式可以是从左到右, 也可以是从两边向中间排列, 两个域的显示 区域之间设置一定的间隔, 比如: 1mm, 当屏幕区域不够时, 域优先级高 的域优先显示, 显示区域足够时要全部显示。 屏幕上显示的内容则由主结 点的状态值决定, 比如: 可以设置电话域的状态值为 1 时, 对应未接可视 电话的图片; 状态值为 2时, 对应未接语音电话的图片;
纵向的是子链表, 子链表和主结点具有——对应的关系, 子链表的链 表头就是主结点, 除去子链表的链表头外, 子链表是用户在对应域上设置 的所有有效的、 不同的状态值、 以及状态值优先级的集合, 子链表中除去
主结点外, 子结点按照每个子结点的状态值优先级减向连接, 当几个子结 点的状态值优先级相同时, 则新插入的子结点更靠近链表头, 即: 更靠近 主结点。
其中, 可以设置状态值优先级最低为 1 , 其次为 2, 最高为 3; 1表示 静态显示, 2表示闪烁显示, 即: 用户正在使用该域对应的业务功能, 3表 示多个图片循环显示, 其中, 1与 2由用户进入该域对应的业务接口时事先 设置带入到子结点相应的数据中, 3则由同一子链表中具有不同状态值的子 结点, 按照一定的 UI原则组合而成, 举个例子来说, 对于电话域来说, 假 如设置电话域的状态值为 1时, 对应未接可视电话的图片; 状态值为 2时, 对应未接语音电话的图片, 在电话域的子链表中的一些子结点有未接的语 音电话, 另外一些子结点有未接的视频电话, 此时, 会将这些子结点的状 态值优先级均设置为 3 , 同时, 启动循环定时器, 循环定时器的时长可以根 据需要设置, 比如: 3s, 循环定时器定时范围内, 显示最靠近子链表的链表 头的子结点的相关信息, 循环定时器超时后, 把最靠近子链表的链表头的 子结点删除, 同时将删除的子结点再插入到子链表中同一状态值优先级离 子链表的链表头最远端。
主结点和子结点的数据均包括: 域 ID、 域优先级、 状态值优先级、 以 及状态值; 其中, 在同一个域中, 所有结点的域 ID、 以及域优先级均相同; 主结点的状态值优先级等于子结点状态值优先级的最大值, 主结点的状态 值为离主结点最近的子结点的状态值; 子结点不包括子结点实时发生的状 态信息, 比如, 对于电话域来说, 子结点实时发生的状态信息可以为未接 的视频电话等, 这些数据保存在域对应的应用模块中, 对电话域来说, 子 结点实时发生的状态信息保存在电话模块中。 具体地讲, 当主结点的状态 值优先级为 1 时, 取最靠近主结点的子结点的状态值为主结点的状态值; 当主结点的状态值优先级为 2 时, 取最靠近链表头的子结点的状态值为主
结点的状态值; 当主结点的状态值优先级为 3 时, 取除去主结点以外的、 状态值优先级为 3的所有子结点的状态值循环作为主结点的状态值。
所述双向链表的数据是动态变化的, 由 model 负责双向链表数据的所 有处理, 比如: 主结点状态值优先级和状态值的更新, 插入子结点数据等。
所述 model向 widget发送变化的数据信息, 具体为: model将更新的 表示对应域的主结点的包括域 ID、 域优先级、 状态值优先级、 以及状态值 的数据信息发送给 widget, 和 /或, model将新增表示域的主结点的包括域 ID、 域优先级、 状态值优先级、 以及状态值的数据信息发送给 widget。
步骤 202: widget根据收到的数据信息, 局部绘制信息条的显示区域、 或调用排布算法全部绘制信息条的显示区域。
这里, 所述 widget根据收到的数据信息, 局部绘制信息条的显示区域、 或调用排布算法全部绘制信息条的显示区域, 具体为:
当 widget收到的是更新的表示对应域的主结点的包括域 ID、域优先级、 状态值优先级、 以及状态值的数据信息时, 由于 widget已经保存过该域的 域 ID、 域优先级, 此时, widget根据收到的状态值优先级、 以及状态值信 息局部绘制信息条的显示区域, 比如: 更换状态值对应的图片等;
当 widget收到的是表示新增域的主结点的包括域 ID、 域优先级、 状态 值优先级、 以及状态值的数据信息时, widget根据收到的域 ID、 域优先级、 状态值优先级、 以及状态值信息, 调用排布算法, 根据现有的显示空间、 要显示的所有域、 域优先级、 以及每个域占据的范围, 划分显示区域, 即: 各个域在显示屏上对应的坐标; 并根据划分的结果, 全部绘制信息条的显 示区域。
在实现动态显示信息条后, 如图 4所示, 所述方法还可以包括: 步骤 401 : 触摸屏控制器将包括点击的事件、 事件发生的坐标、 以及点 击区域对应域的信息发送给 widget;
这里, 用户可以通过触摸屏控制器, 确定点击的事件, 比如: 用户可 以进行点击、 长按、 拖动等动作, 分别对应的事件可以是: 屏幕下压、 滑 动、 以及释放等事件; 将上述事件发生的坐标、 以及点击区域对应域的信 息发送给 widget; 所述对应域的信息, 可以包括: 域 ID等。
步骤 402: widget收到信息后, 根据信息中点击的事件对应的业务相关 的逻辑事件, 启动相应的应用模块;
这里, 所述启动相应的应用模块, 就是启动处理业务相关的逻辑事件 所需要的应用模块, 举个例子来说, 假设逻辑事件属于短信业务, 则需要 启动短信模块, 短信模块负责有关短信的逻辑事件的处理。
举个例子来说, 用户点击未接可视电话的图片, 查看未接的可视电话, 触摸屏控制器可将包括查看未接的可视电话的事件、 事件发生的坐标、 以 及电话域的信息发送给 widget;
widget 收到信息后, 根据查看未接的可视电话的事件对应的业务相关 的逻辑事件, 启动电话模块, 电话模块负责显示未接的可视电话。
下面结合实施例对本发明再作进一步详细的描述。
在插入新的子结点时, model会对双向链表里相应的数据进行处理, 并 将变化后的主结点的状态值优先级、 以及状态值的信息发送给 widget, widget根据收到的信息重新绘制信息条的显示区域, 实现方法如图 5所示, 包括以下步骤:
步骤 501 :用户使用子结点对应的业务接口后,产生新的子结点, model 判断表示新子结点对应域的主结点是否存在, 如果存在, 则执行步骤 502, 否则, 执行步骤 503;
这里, 用户使用子结点对应的业务接口后, 如果双向链表的数据中没 有相应的子结点的数据, 会产生一个新的子结点;
所述 model判断表示新子结点对应域的主结点是否存在, 具体为: 判
断新子结点中的域 ID与双向链表主链表中的主结点的域 ID是否相同, 如 果相同, 则认为表示新子结点对应域的主结点存在, 否则, 认为表示新子 结点对应域的主结点不存在;
用户进入新子结点对应的业务接口后, 新子结点会携带有域 ID、 域优 先级、 状态值优先级、 以及状态值信息。
步骤 502: 将所述新子结点的状态值优先级、 以及状态值插入到主结点 的子链表中, 并检查子链表中除主结点以外的所有子结点是否有能产生新 状态值优先级的组合存在, 如果存在, 则将能产生新状态值优先级组合的 相关子结点的状态值优先级更新为新值, 按状态值优先级减向顺序排列各 个子结点, 之后执行步骤 504, 否则, 结束当前处理流程;
这里, 所述检查子链表中除主结点以外的所有子结点是否有能产生新 状态值优先级的组合存在, 具体为: 检查子链表中除主结点以外的所有子 结点的状态值是否相同, 如果相同, 则认为没有能产生新状态值优先级的 组合存在, 如果不相同, 则认为有能产生新状态值优先级的组合存在; 如果新插入的子结点是能产生新状态值优先级组合的相关子结点, 要 排列在状态值优先级相同的子结点的最前面, 即: 在状态值优先级相同的 子结点里, 新插入的子结点最靠近主结点。
步骤 503: model创建新主结点, 并根据域优先级将新主结点插入到主 链表中, 然后将所述新子结点的状态值优先级、 以及状态值插入到新主结 点对应的子链表中, 之后执行步骤 505;
这里, 由于所述新子结点所在的主结点是新主结点, 此时, 所述新子 结点插入子链表中的位置为最靠近主结点。
步骤 504: model进一步检查主结点的状态值优先级是否等于重排后最 靠近主结点的子结点的状态值优先级, 如果是, 则结束当前处理流程, 否 则, 执行步骤 505。
步骤 505: model根据最靠近主结点的子结点的状态值优先级、 以及状 态值更新主结点的状态值优先级、 以及状态值, 并将更新的表示对应域的 主结点的包括域 ID、 域优先级、 状态值优先级、 以及状态值的数据信息发 送给 widget;
这里, model创建新主结点, 并将所述新子结点的状态值优先级、 以及 状态值插入到新主结点对应的子链表中时, 新主结点的状态值优先级、 以 及状态值就是所述新子结点的状态值优先级、 以及状态值。
步骤 506: widget根据收到的数据信息局部绘制信息条的显示区域、 或 调用排布算法全部绘制信息条的显示区域, 结束当前处理流程;
这里, 当新子结点的主结点存在时, widget根据收到的数据信息局部 绘制信息条的显示区域; 当新子结点的主结点不存在时, widget根据收到 的数据信息, 调用排布算法, 根据现有的显示空间、 要显示的所有域、 域 优先级、 以及每个域占据的范围, 划分显示区域; 并根据排布算法划分的 结果, 全部绘制信息条的显示区域;
如果主结点的状态值优先级为 2时, widget启动一个闪烁定时器, 在 定时器超时后会将主结点状态值对应的图片换成空白。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围, 凡在本发明的精神和原则之内所作的任何修改、 等同替换和改进 等, 均应包含在本发明的保护范围之内。
