Description

一种屏幕显示方法及移动终端 技术领域
本公开涉及移动通讯技术领域,特别涉及一种屏幕显示方法及移动终端。
背景技术
目前主流的Android(安卓)手机,基本采用的都是单屏直板设计。而对于现在的翻盖双屏的设计,一种实现方式为双屏同显,所谓双屏同显,就是同一时刻,多个显示屏幕上显示相同的内容。目前很多手机,都可以同时做手机屏幕的显示,还可以进行HDMI(High Definition Multimedia Interface,高清晰度多媒体接口)的输出。由于显示的内容是同一个,所以Android应用层和Framework(框架)基本不用做修改,只要在显示处理的最后阶段,打包不同数据格式即可。
但是上述双屏同显技术会给用户带来交互使用效果不好的问题,因此,还有一种双屏异显的实现方式,双屏异显即在不同的屏幕上显示不同的内容,此类双屏显示方式,不只是简单的驱动挂载多个屏幕,还需要对Android框架和应用做适配修改,对Android的任务管理机制进行修改,允许多个应用在前台同时运行。显示的内容需要通过Android JAVA层的框架进行扩展,以支持第二个屏幕的显示内容的绘制。这个涉及对Android窗口机制的大量改造,扩充显示接口,支持绘制两个屏幕的内容处理,此种方式实现难度较大,开发成本较高。
发明内容

具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图及具体实施例对本发明进行详细描述。
本发明针对现有的还没有完备的双屏异显方法,造成双屏中的副屏的显示实现起来难度较大,不利于节约成本的问题,提供一种屏幕显示方法及移动终端。
实施例一
图1表示本公开实施例一的屏幕显示方法的流程示意图,如图1所示,本公开实施例一的屏幕显示方法,应用于移动终端,所述移动终端包括第一显示屏幕和第二显示屏幕,其中,所述屏幕显示方法包括:
步骤11,获取移动终端第二显示屏幕上的待显示信息;
需要说明的是,该第一显示屏幕通常指的是移动终端的主屏(主显示屏),第二显示屏幕为移动终端的副屏(副显示屏),且第二显示屏幕上的待显示信息通常指的是应用的状态信息、移动终端的网络信息和系统状态信息中的至少一者;其中,所述应用的状态信息可以为应用程序的通知信息,例如,现在常用的微信、QQ的消息通知;所述网络信息包括网络状态和网络信号中的一种或两种;所述系统状态信息包括:当前时间、移动终端的闹钟提醒信息和移动终端的来电提示信息中的一种或多种;需要说明的是,通常情况下,副屏可以实现主屏上所有信息的显示。
步骤12,根据第二绘制机制,绘制待显示信息的显示界面;
其中,所述第二绘制机制与绘制所述第一显示屏幕的显示界面的第一绘制机制为不同的绘制机制。
需要说明的是,该步骤12的第一绘制机制为通过调用应用层服务的方式进行第一显示屏幕的显示界面的绘制,而第二绘制机制为通过调用本地层服务的方式进行第二显示屏幕的显示界面的绘制,该应用层服务和本地层服务分别隶属于移动终端系统不同的逻辑层,步骤12中,通过调用与绘制主屏的显示界面不同的服务进行副屏的显示界面的绘制,此种方式不会对主屏的显示造成影响,同时可以独立于主屏进行界面显示的单独控制。
步骤13,将所述显示界面在所述第二显示屏幕上显示。
本公开实施例,通过将移动终端的副屏的显示独立于主屏单独进行显示,采用与主屏 不相同的方式控制副屏的显示,避免了对移动终端系统层的改写,实现了主副屏的异显。
可选地,因副屏的显示界面采用的是本地层服务进行绘制的,因此在获取待显示信息时与主屏的获取方式也会有所不同,步骤11在实现时可以为:
通过预设获取机制获取第二显示屏幕上的待显示信息。
需要说明的是,该预设获取机制与获取所述第一显示屏幕的显示信息的获取机制为不同的获取机制。
在一个实施例中,可以采用如下方式实现对第二显示屏幕上的待显示信息的获取:
方式一、通过移动终端的本地层服务(需要说明的是,本地层服务是位于应用层的下层的服务)或调制解调(MODEM)服务,获取移动终端第二显示屏幕上的待显示信息。
通过在本地层服务或调制解调服务中获取待显示信息,不需要与系统应用层服务进行频繁的信息交互,降低了交互复杂性。
方式二、通过移动终端的应用层服务或应用层服务的应用程序编程接口(API),获取移动终端第二显示屏幕上的待显示信息。
需要说明的是,有些待显示信息不能直接在本地层服务中获取,只能借助上层的应用层服务获取。
通常情况下,移动终端会将在应用层服务或应用层服务的应用程序编程接口中获取的待显示信息通过创建文件或属性的方式进行存储,以方便本地层服务的使用。
可选地,图2表示本公开实施例一的步骤12的示例性实现流程示意图,如图2所示,上述步骤12在实现时,包括:
步骤121,通过调用本地层服务支持的基础绘制应用程序编程接口或基础的图形控制库,绘制所述待显示信息的多个界面;
步骤122,将所述多个界面进行合成,生成所述待显示信息的显示界面。
需要说明的是,步骤12在实现时,主要是利用本地层服务中的基础绘制应用程序编程接口或基础的图形控制库进行界面的绘制,不需要借助上层的应用层服务,实现了副屏界面与主屏界面的分别控制。
在步骤122之后,该屏幕显示方法还包括:
步骤123,将所述显示界面进行缓存。
下面在实际用中,对本公开实施例举例说明如下:
本公开实施例在应用时,增加一套副屏显示的流程及刷新机制,用以显示如时间、信号、短信提示、呼叫提示、GPS(Global Positioning System,全球定位系统)信号和闹钟提示等,主屏和副屏可以同一时刻显示,或者主屏不显示只有副屏显示。
副屏独立显示,移动终端可以分别实现副屏与主屏的关闭及开启,以及两个屏幕的显示切换。主屏的内容通过framebuffer1(第一帧缓冲)进行显示,同时从kernel(核心)层面扩充framebuffer2(第二帧缓冲),专门用来显示副屏的内容。副屏的显示完全独立于Android层,在本地单独进行,副屏的UI(User Interface,用户界面)显示,直接使用 NATIVE(本地)层的显示接口库,进行绘制,抛弃Android层面的surfaceflinger(界面的投递者)机制对框架的大量改造。通过独立写一个本地层服务负责完成副屏的所有UI绘制,并调用驱动对famebuffer2进行操作,并和RIL(Radio Interface Layer,无线接口层)层进行通讯(通信机制需要重新开发),并获取网络信息,显示时间,网络状态,GPS信号,闹钟信息等。对屏幕驱动代码进行改造,完成并提供副屏显示的支持,并提供相关显示接口。
图3表示本公开实施例一的移动终端的结构示意图,如图3所示,本公开实施例的移动终端30主要包括:主屏显示框架即处理模块31用于完成主屏的显示处理,副屏显示框架即处理模块32用于完成副屏的显示处理,主屏显示和副屏显示两套显示机制无交互,为各自独立的两套显示服务。
图4表示移动终端主、副屏的显示流程图,如图4所示,主屏的主要显示流程为:
步骤411:主显示屏UI交互显示绘制,移动终端根据设计的需求绘制UI布局;
步骤412:调用Android JAVA层的标准UI API进行绘制;
步骤413:JAVA层的窗口管理器负责UI图形的裁剪及计算;
步骤414:Android的图层显示机制,负责各个图层的显示合成(compose);
步骤415:surfaceflinger最终将显示的图层进行合成,可以软件合成也可以硬件合成,生成最终的显示内容;
步骤416:将最终的显示内容放入framebuffer1;
步骤417:显示驱动负责将framebuffer1的内容取出,并送到主显示屏进行显示;
步骤418:主显示屏显示移动终端绘制的最终的显示内容。
副屏的主要显示流程为:
步骤421:增加副屏代理服务,负责副显示屏的显示绘制组织,并且开机默认启动该副屏代理服务;
步骤422:启动副屏的显示扩展接口或者代理服务进行副屏显示界面的绘制功能;
步骤423:获取网络状态、时间、信号、闹钟、来电等服务;
需要说明的是,因绘制UI界面的NATIVE层没有获取上述信息的接口和服务,所以需进行接口和服务的扩展。步骤424:进行副显示屏UI界面绘制;
步骤425:调用NATIVE的API进行显示绘制;
步骤426:将显示内容进行合成;
步骤427:将合成的显示内容放入framebuffer2;
步骤428:显示驱动负责将framebuffer2的内容取出送副显示屏进行显示。
步骤429:副显示屏显示终端合成的显示内容。
下面对副显示屏上的待显示信息的获取进行说明如下:
图5表示待显示信息的第一种获取流程示意图,如图5所示,该待显示信息的第一种获取流程为:
步骤51:副屏显示代理服务程序发送需要获取网络或者系统状态等信息的指令;
步骤52:NATIVE或者调制解调服务提供网络或者系统状态等信息;
步骤53:通过NATIVE进程通讯机制,实现与副屏显示代理服务程序的通讯;
步骤54:副屏显示代理服务程序根据通讯机制中的消息获取网络或者系统状态等信息。
图6表示待显示信息的第二种获取流程示意图,如图6所示,该待显示信息的第二种获取流程为:
步骤61:副屏显示代理服务程序发送需要获取网络或者系统状态等信息的指令;
步骤62:通过Android JAVA服务或者API获取网络或者系统状态等信息;
步骤63:将获取到的网络或者系统状态等信息通过创建文件或属性等方式存储;
步骤64:副屏显示代理服务程序查询相关属性或者文件节点获取网络或者系统状态等信息。
需要说明的是,双屏同时显示或者只有副屏显示的时候,以副屏只显示时钟、来电、信号、闹钟等为实施例进行介绍。副屏也可以显示比较复杂的界面,副屏也可以支持文本阅读等功能。应用场景中副屏可以选择比较廉价的LCD(Liquid Crystal Display,液晶显示器),并不要求像主屏一样对显示效果有较高的要求。
此处以最基本的终端待机模式需要显示的元素进行说明。比如用户待机的时候,主屏关闭,副屏显示时间来电,状态烂等信息。此时副屏的显示内容,使用设计的副屏显示的绘制进行绘制。此时主屏可以不显示。副屏显示的元素调用Android NAVITVE支持的基础绘制API进行界面元素UI的绘制,或者基础的图形控制库(MINUI)由于界面绘制的UI完全和Android framework服务无关。
此时获取Android系统的时间、网络状态及闹钟信息、来电及短消息等内容,就不像Android上的JAVA服务那么方便,需要独立扩展一层中间层,将上述信息从Android现有的JAVA服务层以通知或查询的方式,告知NATIVE层,使得NATIVE层进行UI元素的布局,这个是其中一种实现方案;第二种实现方案是直接在本地NATIVE层和Android的MODMEM(RIL的支撑层)进行交互或者调用本地NATIVE服务,需要说明的是,此实现方案涉及两个或多个NATIVE服务层之间的消息通知及查询。
将系统的时钟、网络状态、来电、短信等信息获取之后,就可以以此种数据为基础进行UI的布局和绘制,由于此时的绘制完全和Android的基于JAVA层的UI绘制机制分离,需要直接调用NATIVE的绘制API,基于C库的绘制API,比如可以使用MINUI的C图形库处理API等类似的图形库,绘制好的显示内容,直接写入副屏的framebuffer2,再由驱动负责输出到副屏的硬件进行显示。
通过本方案的副屏显示系统,可以方便地实现双屏异像显示功能,解决了Android手机双屏显示的技术难度,绕开了传统的JAVA层显示带来的框架复杂的修改方法,通过NATIVE显示,不适用用Android的surfaceflinger合成机制,另辟蹊径,为产品的差异化 提供了竞争力。
