More importantly, the multitasking mechanism that was only possible on desktop computers has also begun to appear on the terminal. In this way, the terminal can process multiple other tasks simultaneously in the background while processing the task currently being displayed.
尽管引入了多任务处理机制， 但是现有终端， 尤其是移动终端， 所釆 用的多任务切换方法， 在操作上仍然显得不够方便。 例如， 目前较为流行 的一种多任务切换方法是， 用户通过按键操作调出后台任务列表， 然后在 任务列表中选择需要切换的任务。 不难看出， 在终端操作愈发简便的情况 下， 现有多任务切换方法显得非常不便。 发明内容  Although a multi-tasking mechanism has been introduced, the multi-task switching method used by existing terminals, especially mobile terminals, is still inconvenient in operation. For example, a popular multi-tasking method is to call up a background task list by pressing a button, and then select a task to be switched in the task list. It is not difficult to see that the existing multi-task switching method is very inconvenient in the case where the terminal operation is more and more convenient. Summary of the invention

图 1是依据本发明一实施例的终端 100的示范性硬件结构示意图。 图 1所示的终端 100可以是移动终端， 例如但不限于移动电话（例如智能电 话） 、 平板电脑、 个人数字助理 （ Personal Digital Assistant, PDA ) 、 音 视频播放器等。 如图 1所示， 终端 100包括处理器 102、 存储器 104、 触 摸屏 106、 通信接口 108和总线 110。 其中， 处理器 102、 存储器 104、 触 摸屏 106和通信接口 108通过总线 110通信连接。  FIG. 1 is a schematic diagram showing an exemplary hardware structure of a terminal 100 according to an embodiment of the present invention. The terminal 100 shown in Fig. 1 may be a mobile terminal such as, but not limited to, a mobile phone (e.g., a smart phone), a tablet, a personal digital assistant (PDA), an audio player, and the like. As shown in FIG. 1, terminal 100 includes a processor 102, a memory 104, a touch screen 106, a communication interface 108, and a bus 110. The processor 102, the memory 104, the touch screen 106, and the communication interface 108 are communicatively coupled by a bus 110.
处理器 102 可以釆用通用的中央处理器 （Central Processing Unit, CPU ) , 处理器， 应用专用集成电路 ( Application Specific Integrated Circuit, ASIC ) , 或者一个或多个集成电路， 用于执行相关程序， 以实现 本发明实施例所提供的技术方案。  The processor 102 can use a general-purpose central processing unit (CPU), a processor, an application specific integrated circuit (ASIC), or one or more integrated circuits for executing related programs, The technical solution provided by the embodiment of the present invention is implemented.
存储器 104可以是只读存储器 （Read Only Memory, ROM ) , 静态 存储设备， 动态存储设备或者随机存取存储器 （ Random Access Memory, RAM ) 。 存储器 104 可以存储操作系统和其他应用程序。 在通过软件或 者固件来实现本发明实施例提供的技术方案时，用于实现本发明实施例提 供的技术方案的程序代码保存在存储器 104中， 并由处理器 102来执行。  The memory 104 may be a read only memory (ROM), a static storage device, a dynamic storage device, or a random access memory (RAM). The memory 104 can store an operating system and other applications. When the technical solution provided by the embodiment of the present invention is implemented by software or firmware, the program code for implementing the technical solution provided by the embodiment of the present invention is stored in the memory 104 and executed by the processor 102.
触摸屏 106 既是输入设备， 也是输出设备。 作为输入设备， 触摸屏 106可接收用户通过触摸方式输入的数据和信息。 为便于用户输入信息， 以及显示更为丰富的内容，终端 100所配置的触摸屏 106的尺寸通常很大。 通过触摸触摸屏 106 , 用户可以实现文字和命令等信息的输入， 从而使用 终端 100所提供的各种功能， 例如但不限于拨打电话、 发送短消息、 播放 音乐视频、 玩游戏等。 作为输出设备， 触摸屏 106可向用户显示操作结果 等信息。 应注意， 在具体实现过程中， 终端 100还可包含图 1中未示出的 其他输入输出设备， 例如但不限于扬声器等。  The touch screen 106 is both an input device and an output device. As an input device, the touch screen 106 can receive data and information that the user inputs by touch. In order to facilitate user input of information and display of richer content, the size of the touch screen 106 configured by the terminal 100 is usually large. By touching the touch screen 106, the user can input information such as text and commands, thereby using various functions provided by the terminal 100, such as, but not limited to, making a call, sending a short message, playing a music video, playing a game, and the like. As an output device, the touch screen 106 can display information such as an operation result to the user. It should be noted that in a specific implementation process, the terminal 100 may further include other input and output devices not shown in Fig. 1, such as but not limited to a speaker or the like.
通信接口 108使用例如但不限于收发器一类的收发装置，来实现终端 100 与其他设备或通信网络（例如但不限于以太网， 无线接入网 （Radio Access Network, RAN ) , 无线局域网 ( Wireless Local Area Network, WLAN ) 等 )之间的通信。 Communication interface 108 implements the terminal using transceivers such as, but not limited to, transceivers 100 Communication with other devices or communication networks such as, but not limited to, Ethernet, Radio Access Network (RAN), Wireless Local Area Network (WLAN), etc.
总线 110可包括一通路， 在终端 100各个部件 （例如处理器 102、 存 储器 104、 触摸屏 106和通信接口 108 )之间传送信息。  Bus 110 may include a path for communicating information between various components of terminal 100, such as processor 102, memory 104, touch screen 106, and communication interface 108.
通过配置性能更为强大的器件，例如但不限于性能更为强大的处理器 102、 存储器 104、 触摸屏 106、 通信接口 108和总线 110 , 终端 100可以 实现多任务处理， 即在同一时间， 在移动终端上运行多个任务。 在同时运 行的多个任务中，正在通过触摸屏 106的当前显示界面向用户展示并可能 需要与用户进行交互的任务称为前台任务，而处于挂起状态的其他任务则 称为后台任务。 后台任务往往不需要与用户进行交互， 也不需要向用户展 示信息， 因此通常在不打扰用户其它工作的时候执行。 通过任务切换， 后 台任务可以切换至前台， 而切换之前的前台任务切换至后台。 例如， 用户 的终端上同时运行有多个任务， 包括下载任务、 电子邮件收发任务和电子 游戏任务。 其中， 用户当前正在玩对应电子游戏任务的电子游戏， 游戏过 程通过触摸屏的当前显示界面显示给用户。 在这种情况下， 该电子游戏任 务即为前台任务， 其他任务如下载任务和电子邮件收发任务则为后台任 务。  By configuring more powerful devices such as, but not limited to, the more powerful processor 102, memory 104, touch screen 106, communication interface 108, and bus 110, the terminal 100 can implement multitasking, ie, at the same time, on the mobile Run multiple tasks on the terminal. Among the plurality of tasks running simultaneously, a task that is being presented to the user through the current display interface of the touch screen 106 and that may need to interact with the user is referred to as a foreground task, and other tasks in a suspended state are referred to as a background task. Background tasks often do not need to interact with the user, nor do they need to present information to the user, so they are usually executed without disturbing the user's other work. Through task switching, the back-end tasks can be switched to the foreground, and the foreground tasks before switching are switched to the background. For example, a user's terminal runs multiple tasks simultaneously, including download tasks, email tasks, and video game tasks. The user is currently playing an electronic game corresponding to the electronic game task, and the game process is displayed to the user through the current display interface of the touch screen. In this case, the video game task is the foreground task, and other tasks such as download tasks and email sending and receiving tasks are background tasks.
应注意，尽管图 1所示的终端 100仅仅示出了处理器 102、存储器 104、 触摸屏 106、 通信接口 108以及总线 110 , 但是在具体实现过程中， 本领 域的技术人员应当明白， 终端 100 还包含实现正常运行所必须的其他器 件。 同时， 根据具体需要， 本领域的技术人员应当明白， 移动终端 100还 可包含实现其他功能的硬件器件。  It should be noted that although the terminal 100 shown in FIG. 1 only shows the processor 102, the memory 104, the touch screen 106, the communication interface 108, and the bus 110, in a specific implementation process, those skilled in the art should understand that the terminal 100 also Contains other devices necessary to achieve proper operation. Meanwhile, according to specific needs, those skilled in the art should understand that the mobile terminal 100 may also include hardware devices that implement other functions.
图 2是依据本发明一实施例的任务切换方法 200的示范性流程图。图 2所示的任务切换方法 200应用于终端 （例如但不限于移动终端） ， 该终 端配置有一触摸屏， 且该终端上运行有至少一个后台任务。 步骤 202 , 在所述触摸屏的当前显示界面上显示一任务栏， 并在该任 务栏内显示所述至少一个后台任务的任务图标。 2 is an exemplary flow diagram of a task switching method 200 in accordance with an embodiment of the present invention. The task switching method 200 shown in FIG. 2 is applied to a terminal (such as but not limited to a mobile terminal), the terminal is configured with a touch screen, and at least one background task runs on the terminal. Step 202: Display a task bar on a current display interface of the touch screen, and display a task icon of the at least one background task in the task bar.
在具体实现过程中，上述任务栏可以一直显示在终端触摸屏的当前显 示界面上。 此外， 也可实时检测触摸触摸屏的当前显示界面的操作， 并且 在检测到触摸所述触摸屏的当前显示界面的操作时，在当前显示界面上显 示所述任务栏。 在釆用后一种方式的情况下， 为防止显示的任务栏妨碍用 户对当前显示界面上正在显示的主要内容（例如但不限于游戏画面， 视频 画面等）的观看， 在显示上述任务栏之后， 若在一预设显示时长之内没有 检测到对终端的任何操作， 则还可取消对上述任务栏的显示。 在具体实现 过程中， 可根据具体需要来设置上述任务栏的显示时机。  In the specific implementation process, the above task bar can be displayed on the current display interface of the terminal touch screen. In addition, the operation of touching the current display interface of the touch screen can also be detected in real time, and when the operation of touching the current display interface of the touch screen is detected, the task bar is displayed on the current display interface. In the case of the latter method, in order to prevent the displayed task bar from obstructing the user from viewing the main content being displayed on the current display interface (for example, but not limited to a game screen, a video screen, etc.), after displaying the above taskbar If no operation on the terminal is detected within a preset display duration, the display of the above task bar may also be cancelled. In the specific implementation process, the display timing of the above task bar can be set according to specific needs.
此外， 上述任务栏可显示在终端当前显示界面上的任意位置， 例如当 前显示界面的顶部、 底部或者侧边等。 在具体实现过程中， 可根据具体需 要来设置任务栏的显示位置。 当任务栏设置在当前显示界面的顶部时， 当 前显示界面可如图 3A所示。 图 3A所示的当前显示界面 300中包含一任 务栏 302。 该任务栏 302 中包含 3个后台任务对应的任务图标 302、 304 和 306。 本领域的技术人员应当明白， 图 3A所显示的当前显示界面 300 仅用于举例。在具体实现过程中，所显示的任务图标的数量可以不止 3个， 也可以少于 3个。  In addition, the above task bar can be displayed at any position on the current display interface of the terminal, such as the top, bottom or side of the current display interface. In the specific implementation process, the display position of the task bar can be set according to specific needs. When the taskbar is set at the top of the current display interface, the current display interface can be as shown in Figure 3A. The current display interface 300 shown in FIG. 3A includes a task bar 302. The task bar 302 contains task icons 302, 304, and 306 corresponding to three background tasks. Those skilled in the art will appreciate that the current display interface 300 shown in Figure 3A is for illustration only. In the specific implementation process, the number of task icons displayed may be more than three or less than three.
受限于终端触摸屏的尺寸，任务栏所能显示的后台任务的任务图标的 数量是有限的。在这种情况下，还可仅仅显示一部分后台任务的任务图标， 再显示一预设的特殊图标。 在这种情况下， 可在检测到触摸该预设特殊图 标的操作时， 弹出一任务列表， 在该任务列表中显示其任务图标未能显示 在任务栏内的所有后台任务的任务图标， 以供用户进一步选择。  Due to the size of the touch screen of the terminal, the number of task icons of the background tasks that can be displayed on the taskbar is limited. In this case, it is also possible to display only a part of the task icon of the background task, and then display a preset special icon. In this case, when an operation of touching the preset special icon is detected, a task list is popped up, and a task icon whose task icon fails to be displayed in all the background tasks in the task bar is displayed in the task list, For users to choose further.
同时， 受限于终端触摸屏的尺寸， 任务栏本身的显示面积可能很小， 这使得任务栏内显示的任务图标也很小。在这种情况下，为便于用户选择， 可釆用一种放大显示方案， 具体包括： 步骤 A, 检测针对所述任务栏的长时触摸操作， 其中， 所述长时触摸 操作为触摸时长超过预设触摸时长阈值的触摸操作。 At the same time, due to the size of the touch screen of the terminal, the display area of the taskbar itself may be small, which makes the task icon displayed in the taskbar small. In this case, in order to facilitate the user's choice, an enlarged display scheme can be used, which specifically includes: Step A: detecting a long-time touch operation for the task bar, wherein the long-time touch operation is a touch operation in which the touch duration exceeds a preset touch duration threshold.
步骤 B , 在检测到所述长时触摸操作时， 根据该长时触摸操作所对应 的触摸位置计算一待放大区域， 其中， 所述待放大区域为所述任务栏的一 部分， 且所述触摸位置位于该待放大区域之内。  Step B, when the long-time touch operation is detected, calculating an area to be enlarged according to the touch position corresponding to the long-time touch operation, wherein the area to be enlarged is a part of the task bar, and the touch The location is within the area to be enlarged.
