Description

终端及其屏幕的分屏显示方法、存储装置
【技术领域】
本发明涉及终端显示技术领域，具体而言涉及一种终端及其屏幕的分屏显示方法、存储装置。
【背景技术】
随着智能终端的屏幕越来越大，CPU（Central Processing Unit, 中央处理器）、内存、GPU（Graphics Processing Unit, 图形处理器）等硬件功能越来越强大，用户对一个应用程序（Application, APP）同时多界面显示的需求也越来越高。当前，如果终端在运行应用程序的一个任务同时想要运行另一个任务一共用户操作，终端需要将当前运行的任务界面关闭，然后才能切换到另一个任务界面。例如，当用户浏览微信朋友圈时，如果需要和微信朋友聊天，则必须关闭朋友圈界面才能切换到聊天界面。由此可见，当前无法同时显示同一应用程序的多个任务界面，如果用户需要对同一应用程序的多个任务进行操作，就需要在各个任务界面之间来回切换，给用户的操作带来不便。
【发明内容】
鉴于此，本发明提供一种终端及其屏幕的分屏显示方法、存储装置，能够同时显示同一应用程序的多个任务界面，便于用户操作。
本发明一实施例的终端屏幕的分屏显示方法，包括：
设置屏幕显示区包括第一区域和第二区域；
终端接收启动一应用程序的指令，并根据所述指令调用终端系统为应用程序创建的原始堆栈，所述原始堆栈包括至少一活动组件；
终端系统根据原始堆栈创建虚拟堆栈，所述虚拟堆栈的活动组件与原始堆栈的活动组件全部或部分相同；
第一区域显示原始堆栈栈顶的活动组件对应的用户界面，第二区域显示虚拟堆栈栈顶的活动组件对应的用户界面。
本发明一实施例的终端，包括处理器、屏幕及收发器，屏幕和收发器与处理器连接，其中，
处理器用于设置屏幕显示区包括第一区域和第二区域；
收发器用于接收启动终端一应用程序的指令；
处理器还用于根据所述指令调用终端系统为应用程序创建的原始堆栈，所述原始堆栈包括至少一活动组件；
处理器进一步用于根据原始堆栈创建虚拟堆栈，所述虚拟堆栈的活动组件与原始堆栈的活动组件全部或部分相同；
屏幕用于在第一区域显示原始堆栈栈顶的活动组件对应的用户界面，以及在第二区域显示虚拟堆栈栈顶的活动组件对应的用户界面。
本发明一实施例的存储装置，存储有程序数据，所述程序数据能够被执行以实现如下方法：
设置屏幕显示区包括第一区域和第二区域；
接收启动一应用程序的指令，并根据所述指令调用所述存储装置所应用的终端系统为所述应用程序创建的原始堆栈，所述原始堆栈包括至少一活动组件；
根据所述原始堆栈创建虚拟堆栈，所述虚拟堆栈的活动组件与所述原始堆栈的活动组件全部或部分相同；
所述第一区域显示所述原始堆栈栈顶的活动组件对应的用户界面，所述第二区域显示所述虚拟堆栈栈顶的活动组件对应的用户界面。
有益效果：本发明根据原始堆栈创建虚拟堆栈，相当于增加了一个新的堆栈，该新增加的虚拟堆栈的活动组件与原始堆栈的活动组件全部或部分相同，使得同一应用程序的两个任务可以在两个显示区域加载并运行，而后由两个区域分别显示原始堆栈栈顶和虚拟堆栈栈顶的活动组件对应的用户界面，从而使得用户能够对同一应用程序的多个任务进行操作，避免多个任务界面的来回切换，便于用户操作。
【附图说明】

【具体实施方式】
下面将结合本发明实施例中的附图，对本发明所提供的各个示例性的实施例的技术方案进行清楚、完整地描述。在不冲突的情况下，下述各个实施例以及实施例中的特征可以相互组合。
请参阅图1，为本发明一实施例的终端屏幕的分屏显示方法。所述终端屏幕的分屏显示方法可以包括步骤S11~S14。
S11：设置屏幕显示区包括第一区域和第二区域。
本步骤可视为对终端屏幕进行分屏，屏幕可以为终端前部的一体式触摸显示屏。在某一应用程序启动之前，首先需要确定第一区域和第二区域在屏幕上的位置及尺寸。以左右分屏为例，第一区域可以设置于屏幕的左半部分，第二区域设置于屏幕的右半部分。以上下分屏为例，第一区域可以设置于屏幕的上半部分，第二区域设置于屏幕的下半部分。其中，所述第一区域和第二区域均单独具有屏幕的显示功能和触控功能，且两个区域之间可以显示也可以不显示分界线。
本实施例实现分屏的方式包括但不限于以下两种：
一是，终端接收用户输入的分屏选择指令，并根据分屏选择指令在屏幕上设置第一区域和第二区域。例如，终端屏幕显示有分屏选择按钮，用户可以通过点击或拖选等方式选择分屏，终端系统根据用户的选择确定第一区域和第二区域的位置及尺寸。
二是，终端系统中预先存储有配置列表，该配置列表中记录有应用程序与分屏信息的对应关系。可以理解为该配置列表中记录了某一应用程序对应的分屏格局。在某一应用程序启动之前，终端系统直接查询配置列表以确定第一区域和第二区域的位置及尺寸。
终端系统可以通过对屏幕进行坐标标识以记录两个区域在屏幕上的位置及尺寸。例如，结合图2所示，以屏幕的一个顶点为坐标原点、以相垂直的两条边为横坐标轴和纵坐标轴，建立平面直角坐标系，若将屏幕布局为左右两个区域11、12，则根据两条边的长度以及两个区域的面积之比，即可得到两个区域11、12的坐标范围。
S12：终端接收启动一应用程序的指令，并根据所述指令调用终端系统为应用程序创建的原始堆栈，所述原始堆栈包括至少一活动组件。
S13：终端系统根据原始堆栈创建虚拟堆栈，所述虚拟堆栈的活动组件与原始堆栈的活动组件全部或部分相同。
以Android（安卓）系统为例，一个应用程序包含多个任务（task），一个任务包括多个活动组件（activity），一个活动组件在终端屏幕上对应显示一个用户界面（User Interface, UI），终端系统可以连续启动很多活动组件以进行多个用户界面的显示。所有打开的活动组件均存储于堆栈中。同一任务的所有活动组件均分配在一个堆栈中。在堆栈栈顶的活动组件是当前正在运行并显示的活动组件。每个活动组件按照先入后出的原则被执行，例如，当新启动一个活动组件时，该新的活动组件将压入堆栈栈顶中，它成为当前正在运行并显示的活动组件，而之前处于栈顶的活动组件在该新的活动组件被执行后才执行。
本实施例对现有Android系统框架层的处理机制进行改进，创建额外的堆栈。若将应用程序原有的堆栈视为原始堆栈，则本实施例额外创建的堆栈视为虚拟堆栈。以图2所示左右分屏为例，在第一区域21载入应用程序后，该应用程序的所有活动组件均存储于原始堆栈中，本实施例将该原始堆栈的部分任务或所有任务的活动组件复制至虚拟堆栈中。该虚拟堆栈的活动组件也按照先入后出原则被执行。
在本发明的一个实施例中，虚拟堆栈和原始堆栈中的活动组件由栈顶至栈底的排列顺序不相同。也就是说，虚拟堆栈中各个任务的执行顺序与原始堆栈中各个任务的执行顺序可以不相同。
S14：第一区域显示原始堆栈栈顶的活动组件对应的用户界面，第二区域显示虚拟堆栈栈顶的活动组件对应的用户界面。
继续参阅图2，以原始堆栈包括沿栈底至栈顶方向排序的任务task1、task2、task3和task4为例，第一区域21显示任务task4的活动组件所对应的用户界面，其中该活动组件位于原始堆栈的栈顶。同理，虚拟堆栈包括沿栈底至栈顶方向排序的任务task1和task3，第二区域22显示任务task3的位于栈顶的活动组件所对应的用户界面。
如果当前虚拟堆栈中没有用户所要运行的任务，则用户可以通过点击操作以下达调取应用程序中所有可以被创建的任务的指令，终端系统解析应用配置文件（AndroidManifest.xml），调取应用程序中所有可以被创建的任务，并可以以列表形式显示于第二区域22以供用户选择。在用户选择后，虚拟堆栈便新加入该被选择的任务。
由上述可知，本实施例通过增加一个新的堆栈——虚拟堆栈，使得同一应用程序可以在一个屏幕的两个显示区域加载并运行，由此用户能够对各个显示区域的任务的用户界面进行操作，即实现对同一应用程序的多个任务的用户界面进行操作，避免多个任务界面的来回切换，便于用户操作。也就是说，本实施例在Android系统框架层实现了各个分屏的隔离管理，使得各个分屏分别运行同一应用程序的各个任务，且互不影响，最终实现单应用多任务的显示及操作。
例如，终端开启微信这一应用程序后，可以在第一区域运行朋友圈这一任务，则第一区域显示操作朋友圈产生的所有用户界面，在第二区域运行聊天这一任务，则第二区域显示聊天时产生的所有用户界面。用户在第一区域浏览微信朋友圈时，可以在第二区域与微信朋友聊天，而无需在屏幕上进行朋友圈界面和聊天界面的切换，操作简便。
本发明还能够在应用程序的多任务分屏显示过程中对分屏显示进行动态调整。具体地，终端接收用户的分屏修改指令，该分屏修改指令可以通过点击或拖选等方式产生，而后终端系统根据用户的分屏修改指令确定修改后的第一区域和第二区域的位置及尺寸，并根据所述分屏修改指令修改堆栈管理的窗口位置参数和/或窗口尺寸参数，进一步根据修改后的窗口位置参数和/或窗口尺寸参数对第一区域和第二区域进行重新布局，并显示重新布局后的用户界面。
虽然第一区域和第二区域单独运行不同任务，但两个区域之间可以进行数据交互。参阅图3，为本发明另一实施例的终端屏幕的分屏显示方法。所述终端屏幕的分屏显示方法可以包括步骤S31~S36。
S31：设置屏幕显示区包括第一区域和第二区域。
S32：终端接收启动一应用程序的指令，并根据所述指令调用终端系统为应用程序创建的原始堆栈，所述原始堆栈包括至少一活动组件。
S33：终端系统根据原始堆栈创建虚拟堆栈，所述虚拟堆栈的活动组件与原始堆栈的活动组件全部或部分相同。
S34：第一区域显示原始堆栈栈顶的活动组件对应的用户界面，第二区域显示虚拟堆栈栈顶的活动组件对应的用户界面。
S35：终端接收用户的拖拽指令，所述拖拽指令为用户将选中的第一区域和第二区域中一者的用户界面拖曳至另一者中的指令。
S36：终端系统将所述拖拽指令包括的用户界面所对应的活动组件发送给第一区域和第二区域中另一者的堆栈。
当在分屏中同时启动两个任务后，例如，结合图2所示，第一区域21中进行任务task4，并显示任务task4位于原始堆栈栈顶的活动组件1所对应的用户界面1，第二区域22中进行任务task3，并显示任务task3位于虚拟堆栈栈顶的活动组件2所对应的用户界面2，用户界面1和用户界面2可以通过用户拖拽方式进行实时数据交换。
具体而言，用户选中用户界面1（的数据）并将其拖拽至用户界面2，终端基于IPC（Inter-Process Communication, 进程间通信）技术并通过系统的任务管理策略中心（Activity Manager Service）将原始堆栈的活动组件1（的被选中数据）发送给虚拟堆栈。同理，用户也可以通过拖拽方式将第二区域22中的任务数据发送给第一区域21中的任务。其中，虚拟堆栈和原始堆栈中所有任务的活动组件（的数据）可以通过同一个数据接口进行交互。
应该理解到，上述各个实施例之间可以相互结合，并且上述功能如果以软件功能的形式实现并作为独立产品销售或使用时，可存储在一个电子设备可读取存储介质中，即，本发明还提供一种存储有程序数据的存储装置，所述程序数据能够被执行以实现上述实施例的方法，该存储装置可以为如U盘、光盘、服务器等。也就是说，本发明的各个实施例可以以软件产品的形式体现出来，其包括若干指令用以使得一台智能终端执行各个实施例所述方法的全部或部分步骤。

处理器41用于设置屏幕42的显示区包括第一区域和第二区域。
收发器43用于接收启动终端40一应用程序的指令。
处理器41还用于根据所述指令调用终端40的系统为应用程序创建的原始堆栈，所述原始堆栈包括至少一活动组件。
处理器41进一步用于根据原始堆栈创建虚拟堆栈，所述虚拟堆栈的活动组件与原始堆栈的活动组件全部或部分相同。
屏幕42用于在第一区域显示原始堆栈栈顶的活动组件对应的用户界面，以及在第二区域显示虚拟堆栈栈顶的活动组件对应的用户界面。
在应用程序的多任务分屏显示过程中，终端40还可以对分屏显示进行动态调整。具体地，收发器43用于接收用户的分屏修改指令，该分屏修改指令可以通过点击或拖选等方式产生。处理器41根据用户的分屏修改指令确定修改后的第一区域和第二区域的位置及尺寸，并根据所述分屏修改指令修改堆栈管理的窗口位置参数和/或窗口尺寸参数，进一步根据修改后的窗口位置参数和/或窗口尺寸参数对第一区域和第二区域进行重新布局。屏幕42显示重新布局后的用户界面。
虽然第一区域和第二区域单独运行不同任务，但两个区域之间可以进行数据交互。也就是说，收发器43还用于接收用户的拖拽指令，所述拖拽指令为用户将选中的第一区域和第二区域中一者的用户界面拖曳至另一者中的指令。而后，处理器41用于将所述拖拽指令包括的用户界面所对应的活动组件发送给第一区域和第二区域中另一者的堆栈。其中，所述虚拟堆栈和原始堆栈中的所有活动组件可以通过同一个数据接口进行交互。
