Description

一种快速返回界面的方法及电子设备
本申请要求于2021年06月26日提交中国专利局、申请号为202110715180.1、申请名称为“一种快速返回界面的方法及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子设备技术领域，尤其涉及一种快速返回界面的方法及电子设备。
背景技术
一个应用程序可以包括多个应用程序活动(Activity)。用户在使用应用程序的过程中，应用程序会根据用户的操作生成多个活动，这多个活动会按照访问顺序依次进入堆栈。当堆栈中的活动数量较多时，若用户想要返回到之前打开的一个界面(例如应用程序的主界面)，需多次触发返回键逐级返回，活动也会按照访问顺序的反向顺序依次弹出堆栈，用户操作繁琐。或者，用户可以直接退出该应用程序，再重新打开该应用程序，但这样之前的操作记录会丢失，用户可能需要重新操作，操作繁琐且违背正常感知，用户体验感差。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。本申请实施例的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
本申请实施例提供了一种快速返回界面的方法，应用于电子设备。电子设备可以响应于一次返回操作，将活动任务栈(简称活动栈)(Activity Stack)中的多个活动(Activity)出栈，以执行返回多个用户界面的操作，即实现快速返回界面的效果，避免用户多次执行返回操作，操作更加便捷，提升用户体验感。
本申请中，返回操作例如但不限于为：作用于应用程序内置的返回键的操作，作用于三键导航中的返回键的操作，手势导航中的返回操作(如从屏幕左边缘或右边缘向内滑动)，语音(如发出声音：“返回”)，手势(如张开手指并从左往右挥动)。上述返回键可以是虚拟按键，也可以是实体按键。
本申请中，电子设备可以运行至少一个应用，一个应用可以包括至少一个应用程序活动。可选地，一个应用程序活动可以对应一个用户界面，为便于描述，本申请实施例将应用程序活动简称为活动，或应用活动。应用程序活动可以是安卓(Android)系统中的活动(Activity)，还可以是IOS等其他操作系统中的应用程序活动，本申请对此不作限定。
以下实施例以应用程序活动为Android系统中的Activity为例进行说明。
其中，Activity是Android系统中用户和应用程序之间进行交互的接口。Activity供应用程序在其中绘制界面。Activity通常会填满屏幕，但也可能比屏幕小，并浮动在其他Activity上面。一个Activity是用户可以直观交互的东西，可以表现为一个用户界面，可以理解为一个Activity对应一个用户界面。一个应用可以包含多个用户界面，也可以理解为是一个应用可以包含多个Activity。操作应用程序时，偶尔需要调用多个Activity来完成需求。每个Activity可以启动另一个Activity，以执行不同的操作。例如，用户启动电子邮件应用后可以先进入应用的主界面，主界面对应的Activity可以启动其他Activity，以提供执行写邮件和打开邮件这类任务的用户界面。
在操作应用程序的过程中，Andord系统可以使用堆栈的方式管理Activity，可以称为活动任务栈(Activity Stack)，也可称为Task，Task便于线性记录Activity示例。Task在安卓开放源代码项目(Android open source project)中，实际为一种动态数组(array list)。堆栈的特性是压入(也可称进入)和弹出，并且采用先进后出的原则，即先压入堆栈(也可称进入堆栈)的Activity比后压入堆栈的Activity先弹出堆栈。一个Task可以包括至少一个Activity。一个Task中的多个Activity可以是同一应用包括的Activity，也可以是不同应用包括的Activity。第一个压入Task且最后一个弹出Task的Activity，可以理解为是Task中位于最底层的Activity，可以称为根部Activity，最后一个压入Task且第一个弹出Task的Activity，可以理解为是Task中位于最顶层的Activity，可以称为顶部Activity。
在一些实施例中，根部Activity通常对应应用的主界面。顶部Activity通常是正在运行、用户正在交互的Activity，也可以称为前台活动(foreground activity)，前台活动对应的用户界面用户可见。
本申请中，每次启动新的Activity时，该Activity可以压入Task，成为Task的顶部Activity。用户可以触发返回操作，以返回顶部Activity之前压入Task的一个Activity，直到Task的根部Activity被弹出。因此，Task也可称为回退栈(back stack)。具体示例如下图1所示。

如图9所示，快速返回操作和普通返回操作的作用区域可以相同(均为返回区域)，但操作方式可以不同，普通返回操作可以为从屏幕左边缘向内水平滑动的操作，快速返回操作可以为从屏幕左边缘向内滑动且滑动方向为对角向上的操作。不限于此，也可以是普通返回操作和快速返回操作的滑动距离不同，本申请对具体操作方式不作限定。快速返回操作的示例和上图8类似，只是快速返回操作替换为从屏幕左边缘向内滑动，且滑动方向为对角向上的操作。
在一些实施例中，电子设备可以显示提示信息，用户可以基于提示信息执行快速返回操作。示例性地，提示信息用于指示以下至少一项：快速返回操作的作用区域、作用控件、操作方式、返回界面、返回界面对应的应用，具体示例如下图10-图11、图15-图16所示。
请参见图10，图10示例性示出了又一种返回操作的示意图。
如图10的(A)所示，电子设备显示用户界面520时，可以接收作用于返回区域2且滑 动距离为第一距离的滑动操作，响应于该滑动操作，电子设备可以在用户界面520上显示第二提示信息521的部分内容。在一些实施例中，第二提示信息521用于指示用户执行快速返回操作后返回显示的用户界面：购物应用的主界面，例如第二提示信息521为购物应用的图标。第二提示信息521显示的内容多少是根据滑动操作的滑动距离确定的。电子设备可以继续接收上述作用于返回区域2的滑动操作，但此时滑动距离变更为第二距离，第二距离大于第一距离。响应于该滑动操作，电子设备可以在用户界面520上显示第二提示信息521的全部内容，具体可参见图10的(B)所示的用户界面520。
如图10的(C)所示，电子设备可以接收作用于第二提示信息521的用户操作(例如触摸操作、滑动操作等)，即可以接收快速返回操作，响应于快速返回操作，直接返回显示购物应用的主界面：图8的(F)所示的用户界面300。
请参见图11，图11示例性示出了又一种返回操作的示意图。
如图11的(A)所示，电子设备显示用户界面520时，可以接收作用于返回区域2且滑动距离为第一距离的滑动操作，此时用户界面520保持不变。电子设备可以继续接收上述作用于返回区域2的滑动操作，但此时滑动距离变更为第二距离，第二距离大于第一距离。响应于该滑动操作，电子设备可以在用户界面520上显示第二提示信息521，具体如图11的(B)所示。电子设备可以继续接收上述作用于返回区域2的滑动操作，但此时滑动距离变更为第三距离，第三距离大于第二距离，即可以接收快速返回操作，具体如图11的(C)所示。响应于快速返回操作，电子设备可以直接返回显示购物应用的主界面：图8的(F)所示的用户界面300。
在一些实施例中，用户可以在浏览用户界面的过程中可以对用户界面执行特定操作(可称为收藏用户界面)，收藏的用户界面用于在响应于快速返回操作时返回显示，具体示例如下图12所示。
请参见图12，图12示例性示出一种特定操作的示意图。
如图12所示，电子设备显示的用户界面420可以还包括新增的收藏选项424。电子设备可以响应于作用于收藏选项424的用户操作(例如触摸操作)，确定当前显示的用户界面420为响应于快速返回操作返回显示的用户界面。可以理解地，电子设备可以在安装的全部应用或部分应用的用户界面显示收藏选项424，电子设备可以在一个应用的全部用户界面或部分用户界面显示收藏选项424。
不限于此，还可以通过应用程序中已有的控件收藏用户界面，例如上图8的(B)所示的用户界面510中，电子设备可以响应于作用于购物选项“收藏”的用户操作(例如触摸操作)，确定当前显示的用户界面510为返回界面。
本申请中，电子设备显示的任意一个用户界面可以被收藏。
在一些实施例中，可收藏的用户界面的数量可以小于或等于预设的最大数量。可选地，电子设备可以将用户最近收藏的第一数量个用户界面，确定为第一数量种类型的快速返回操作对应返回显示的用户界面，第一数量等于最大数量。示例性地，假设用户在使用应用A的过程中，依次收藏了用户界面A、B和C，以及假设最大数量为2，则电子设备可以将用户界面B和用户界面C，确定为两种类型的快速返回操作对应返回显示的用户界面。
不限于上述列举的收藏操作，在具体实现中，用户还可以通过握拳手势等手势操作来收藏用户界面，本申请对收藏操作的具体实现方式不作限定。
不限于上述列举的情况，在具体实现中，电子设备也可以预设返回界面，例如预设返回界面为当前应用第一次打开的用户界面(如应用主界面)。电子设备也可以按照预设规则确定 返回界面，例如记录用户界面的浏览时长，浏览时长大于或等于预设浏览时长的用户界面为快速返回操作对应返回显示的用户界面。
在一些实施例中，快速返回操作可以包括多种类型，不同类型的快速返回操作对应返回显示不同的用户界面，不同类型的快速返回操作例如但不限于是作用区域不同，作用控件不同，操作方式不同等等，具体示例如下图13-图16所示。
以下实施例以快速返回操作包括两种类型：第一快速返回操作和第二快速返回操作为例进行说明。
请参见图13，图13示例性示出又一种返回操作的示意图。
如图13所示，快速返回操作可以包括两种类型：第一快速返回操作和第二快速返回操作，这两种类型的操作的作用区域可以不同，如图13的(A)所示，第一快速返回操作的作用区域可以为返回区域3，如图13的(B)所示，第二快速返回操作的作用区域可以为返回区域4。而普通返回操作的作用区域可以为返回区域1，其中，返回区域1位于返回区域3和返回区域4的上侧，返回区域3位于返回区域4的上侧，不限于此，在具体实现中，也可以是返回区域3位于屏幕左下侧，返回区域4位于屏幕右下侧，本申请对作用区域的具体位置不作限定。
请参见图14，图14示例性示出又一种返回操作的示意图。
如图14所示，快速返回操作可以包括两种类型：第一快速返回操作和第二快速返回操作。普通返回操作、第一快速返回操作和第二快速返回操作的作用区域可以相同(均为返回区域)，但操作方式可以不同，如图14的(A)所示，第一快速返回操作可以为从屏幕左边缘向内滑动且滑动方向为对角向上的操作，如图14的(B)所示，第二快速返回操作可以为从屏幕左边缘向内滑动且滑动方向为对角向下的操作，而普通返回操作可以为从屏幕左边缘向内水平滑动的操作。
请参见图15，图15示例性示出又一种返回操作的示意图。
如图15的(A)所示，电子设备显示用户界面520时，可以接收作用于返回区域2且滑动距离为第一距离的滑动操作，此时用户界面520保持不变。电子设备可以继续接收上述作用于返回区域2的滑动操作，但此时滑动距离变更为第二距离，第二距离大于第一距离。响应于该滑动操作，电子设备可以在用户界面520上显示第三提示信息522A、第四提示信息522B、第五提示信息522C，具体如图15的(B)所示。这三个提示信息可以分别对应三种类型的快速返回操作，可以包括和返回界面对应的图标和文字。第三提示信息522A指示的返回界面为购物应用的主界面：用户界面300，第四提示信息522B指示的返回界面为：图12中通过新增的收藏选项424收藏的用户界面420，第五提示信息522C指示的返回界面为：通过购物应用已有的收藏选项511收藏的用户界面510。
如图15的(C)所示，电子设备可以继续接收上述滑动操作，此时滑动操作的滑动方向从水平变更为对角向上，且作用于第三提示信息522A，即可以接收第一快速返回操作，响应于第一快速返回操作，直接返回显示用户界面300。不限于此，电子设备还可以接收针对第四提示信息522B或第五提示信息522C的滑动操作，以返回对应的返回界面。
请参见图16，图16示例性示出又一种返回操作的示意图。
如图16的(A)所示，电子设备显示用户界面520时，可以响应于作用于返回区域2的滑动操作，在用户界面520上显示第三提示信息522A、第四提示信息522B、第五提示信息522C，具体说明和图15中的提示信息一致。电子设备可以接收作用于任意一个提示信息的用户操作，即可以接收快速返回操作，响应于快速返回操作，直接返回显示和作用的提示信 息对应的返回界面。例如，电子设备可以接收作用于第三提示信息522A的点击操作，即可以接收第一快速返回操作，响应于第一快速返回操作，直接返回显示用户界面300，具体示例可参见图16的(B)。
在一些实施例中，电子设备可以响应于用户操作，分屏显示当前界面和上一级界面之前打开的用户界面，具体示例如下图17-图18所示。
请参见图17，图17示例性示出一种分屏显示的用户界面实施例的示意图。
如图17的(A)所示，电子设备可以显示用户界面520，用户界面520可以包括第三提示信息522A、第四提示信息522B、第五提示信息522C，触发显示提示信息的方式可参见上图16，提示信息的说明可参见上图15。电子设备可以接收作用于第五提示信息522C的拖拽操作，该拖拽操作用于将第五提示信息522C拖拽至屏幕上方，响应于该拖拽操作，电子设备可以显示分屏界面，具体示例如图17的(B)所示。
如图17的(B)所示，电子设备显示的分屏界面可以包括上下两个窗口：第一窗口1810和第二窗口1820，以及这两个窗口之间的移动控件1830。第一窗口1810用于显示第五提示信息522C，第二窗口1820用于显示用户界面520(仅示出部分)，移动控件1830用于调整第一窗口1810和第二窗口1820的相对大小，例如将移动控件1830往上移动时，第一窗口1810变小，第二窗口1820变大。电子设备检测到作用于第五提示信息522C的触摸操作(也可理解为是上述拖拽操作)取消时，可以在第一窗口1810显示第五提示信息522C对应的返回界面：用户界面510，具体可参见图17的(C)。也即电子设备在第一窗口1810检测到第五提示信息522C对应的快速返回操作，因此可以直接在第一窗口1810返回显示第五提示信息522C对应的返回界面。
在一些实施例中，用户还可以在图17的(C)所示的用户界面520下，将第三提示信息522A或第四提示信息522B拖拽至第一窗口1810，则电子设备可以在第一窗口1810显示拖拽的提示信息对应的返回界面，并且在第一窗口1810或第二窗口1820上显示第五提示信息522C。
在一些实施例中，用户还可以在图17的(C)所示的用户界面520下，点击第三提示信息522A或第四提示信息522B，则电子设备可以在第二窗口1820显示点击的提示信息对应的返回界面。
在一些实施例中，电子设备可以接收作用于第二窗口1820的快速返回操作，例如作用于第三提示信息522A的触摸操作，响应于该触摸操作，返回显示第三提示信息522A对应的返回界面，或者作用于第四提示信息522B的触摸操作，响应于该触摸操作，返回显示第四提示信息522B对应的返回界面。

如图18的(A)所示，电子设备可以在折叠屏显示上图17的(A)所示的用户界面520，其中，第三提示信息522A、第四提示信息522B、第五提示信息522C均位于第一显示区域。图18的(A)到图18的(C)的过程，和上图17的(A)到图17的(C)的过程类似，只 是作用于第五提示信息522C的拖拽操作的拖拽方向不同，图18中，该拖拽操作用于将第五提示信息522C从第一显示区域拖拽至第二显示区域。分屏的显示窗口也不同，图18中，用于显示原用户界面520的显示窗口为第一显示区域，用于显示第五提示信息522C以及对应的返回界面的为显示窗口为第二显示区域。图18中，移动控件1910位于弯折线上，但具体功能和图17所示的移动控件1830一致。具体过程可参见图17所示说明，不再赘述。
在一些实施例中，电子设备可以接收作用于第一显示区域的快速返回操作，例如作用于第三提示信息522A的触摸操作，响应于该触摸操作，返回显示第三提示信息522A对应的返回界面，或者作用于第四提示信息522B的触摸操作，响应于该触摸操作，返回显示第四提示信息522B对应的返回界面。

如图20的(A)所示，电子设备显示用户界面520时，可以接收作用于返回区域2且滑动距离为第一距离的滑动操作，此时用户界面520保持不变。电子设备可以继续接收上述作用于返回区域2的滑动操作，但此时滑动距离变更为第二距离，第二距离大于第一距离。响应于该滑动操作，电子设备可以在用户界面520上显示第六提示信息523A和第七提示信息523B，具体如图20的(B)所示。这两个提示信息可以位于用户手指触摸位置的附近，例如触摸位置的右侧。这两个提示信息可以分别对应两种类型的返回操作，用于分别返回不同应用的用户界面，这两个提示信息可以包括返回界面的应用的图标。第六提示信息523A包括购物应用的图标，第七提示信息523B包括视频应用的图标，电子设备可以接收作用于第六提示信息523A的触摸操作，具体如图20的(C)所示，作用于第七提示信息523B的触摸操作类似。电子设备可以响应于作用于第六提示信息523A的触摸操作，返回显示购物应用中第一个打开的用户界面，即图19的(D)所示的用户界面430。电子设备可以响应于作用于第七提示信息523B的触摸操作，返回显示视频应用的主界面，即图19的(A)所示的用户界面2510。

不限于上述示例，电子设备也可以响应于接收的触发操作，显示提示信息，触发操作例如从屏幕右边缘向内水平滑动的操作，从屏幕左边缘向内的长滑动操作等等，本申请对触发显示提示信息的具体方式不作限定。
不限于上述示例，快速返回操作也可以是滑动距离较长的长滑动操作，本申请对快速返回操作的具体类型不作限定。
不限于上述示例，图4所示实施例中，还可以跳转显示更多的用户界面，例如图4的(A)到图4的(D)之间还有多个用户界面，图4的(D)到图4的(F)之间还有多个用户界面。因此，图5所示实施例中，用户需执行更多的返回操作，以及返回显示更多的用户界面，才能返回到图5的(F)所示的用户界面300。图6和图8所示实施例中，电子设备可以响应于 快速返回操作，返回更多的用户界面。图19所示实施例类似，本申请对跳转显示过的用户界面的数量，返回的用户界面的数量不作限定。

应用选项3080可以包括多个应用的快速返回功能的功能开关，例如视频应用的功能开关3080A、购物应用的功能开关3080B、社交应用的功能开关3080C。任意一个应用的功能开关用于用户开启或关闭针对该应用的快速返回功能。在一些实施例中，应用选项3080中的应用可以是电子设备默认设置的，例如，上图3-图20所示的购物应用和视频应用为可以开启快速返回功能的应用。用户使用购物应用和视频应用的过程中，均可以从一个用户界面A开始，中间跳转多个用户界面到另一个用户界面B，并且返回用户界面时需要多次执行普通返回操作才能返回到用户界面A，或者用户界面A和用户界面B之间的显示的用户界面。而通常不可以开启快速返回功能的应用，例如图库应用，通常是从一个用户界面C(例如图片列表)跳转到另一个用户界面D(例如图片A的界面)，然后再返回用户界面C，再从用户界面C跳转到另一个用户界面E(例如图片B的界面)，对于从用户界面C跳转到的其他用户界面，往往只需要少量的返回操作即可返回到用户界面C。
不限于上述示例，用户还可以设置不同滑动距离对应返回不同的用户界面，是否显示提示信息，提示信息的具体形式等，本申请对用户可以设置的快速返回功能不作限定。
不限于上述示例，电子设备还可以默认开启某些应用(例如购物应用和视频应用)的快速返回功能，或者电子设备可以默认开启所有应用的快速返回功能。本申请对开启快速返回 功能的应用不作限定。

基于上图1、图2A-图2B、图3-图25所示的实施例，接下来介绍本申请提供的快速返回界面的方法。
请参见图26，图26是本申请实施例提供的一种快速返回界面的方法。该方法可以应用于图2A所示的电子设备100。该方法可以应用于图2B所示的电子设备100。该方法可以包括但不限于如下步骤：
S101：电子设备接收普通返回操作。
S102：电子设备接收快速返回操作。
具体地，普通返回操作和快速返回操作可以但不限于满足以下至少一项：作用的区域不同，作用的控件不同，操作方式不同(例如操作方向不同，触摸距离不同)等，具体示例可参见上图3-图25中的普通返回操作和快速返回操作。在一些实施例中，电子设备接收普通返回操作(即S101)后，可以跳转到S103。在另一些实施例中，电子设备接收快速返回操作(即S102)后，可以跳转到S105。
S103：电子设备判断是否满足快速返回的触发条件。
在一些实施例中，电子设备可以判断接收第一预设次数次普通返回操作的时段是否小于或等于第一预设时长，若是则确定满足快速返回的触发条件，否则确定不满足快速返回的触发条件。在另一些实施例中，电子设备可以判断第一预设时长内接收的普通返回操作的次数是否大于或等于第一预设次数，若是则确定满足快速返回的触发条件，否则确定不满足快速返回的触发条件。
在一些实施例中，电子设备确定不满足快速返回的触发条件时，可以跳转到S104。在另一些实施例中，电子设备确定满足快速返回的触发条件时，可以跳转到S105。
示例性地，假设执行S101之前电子设备接收了K次普通返回操作，K为正整数，这K次普通返回操作中最早接收到的普通返回操作的时刻为第一时刻，电子设备执行S101的时刻为第二时刻。快速返回的触发条件可以但不限于包括：第一时刻和第二时刻的差值小于或等于第一预设时长，和/或，(K+1)小于或等于第一预设次数。
S104：电子设备执行普通返回方法。
具体地，确定接收普通返回操作且不满足快速返回的触发条件时，电子设备可以返回当前界面的上一级界面(即执行普通返回方法)，具体示例可参见上图5。
S105：电子设备执行快速返回方法。
具体地，确定接收普通返回操作且满足快速返回的触发条件，或者，接收快速返回操作时，电子设备可以返回多个用户界面，直接返回显示预设返回界面，具体示例可参见上图6-图18。其中，预设返回界面可以是电子设备在当前界面之前显示过的，除上一级界面外的任意一个用户界面，例如第一个打开的应用界面，例如应用的主界面。在一些实施例中，预设返回界面可以和当前界面属于同一个应用的用户界面，在另一些实施例中，预设返回界面和当前界面属于不同应用的用户界面。
在一些实施例中，预设返回界面可以有多个，在一些实施例中，快速返回操作可以包括多种类型，不同类型的快速返回操作对应返回到不同的用户界面，不同类型的快速返回操作 例如但不限于是作用的区域不同，作用的控件不同，操作方式不同(例如操作方向不同，触摸距离不同)等等。在一些实施例中，不同类型的快速返回操作对应返回的不同的用户界面，可以是同一个应用的，具体示例可参见上图6-图18，在另一些实施例中，也可以是不同应用的，具体示例可参见上图19-图20。
在一种可能的实现方式中，电子设备的软件系统可以是Android系统，可以将电子设备显示的一个用户界面理解为是对应一个Activity，而Activity是通过Task来管理的。Task也可称为回退栈(back stack)。因此，打开一个用户界面，可以理解为是将该用户界面对应的Activity压入Task(即入栈)。执行返回操作以返回当前界面的上一级界面，可以理解为是弹出Task的顶部Activity(也可称栈顶活动)(即当前界面对应的Activity)(即出栈)，具体示例可参见上图1。因此，图26所示的快速返回方法用于返回预设返回界面，可以理解为是：快速返回方法用于将Task中预设返回界面对应的Activity之上的多个Activity出栈，以将预设返回界面对应的Activity设置为Task的顶部Activity。
在一些实施例中，假设电子设备运行有第一活动栈，电子设备显示第一应用程序的第二界面时，和第二界面关联的第二活动(也可称为和第二界面对应的第二活动)压入(也可称为进入)第一活动栈，然后，电子设备显示第一应用程序的第一界面时，和第一界面关联的第一活动压入第一活动栈。示例性地，上图4所示过程中，电子设备响应于每次的用户操作(用于打开/跳转到当前显示界面的下一级界面)，依次显示用户界面300、用户界面410、用户界面420、用户界面430、用户界面510和用户界面520，也就是将用户界面300、用户界面410、用户界面420、用户界面430、用户界面510和用户界面520对应的Activity压入第一活动栈。其中，用户界面520例如为第一界面(即当前显示界面)，则第一活动栈的栈顶活动为用户界面520关联的第一活动。用户界面300例如为第二界面，则第一活动栈的底部Activity(也可称栈底活动)为用户界面300关联的第二活动，不限于此，用户界面410、用户界面420和用户界面430中任意一个界面也可以为第二界面，第二界面关联的第二活动可以理解为是栈中活动(即栈底活动和栈顶活动之外的活动)，但可以理解的是，第二活动不为用户界面510(即当前显示界面的上一级界面)关联的活动。
在一些实施例中，电子设备显示第一应用程序的第一界面时，确定接收普通返回操作且不满足快速返回的触发条件时，可以返回第一界面的上一级界面，也就是说，电子设备可以弹出第一活动栈的栈顶活动。示例性地，上图5所示过程，电子设备显示用户界面520时，可以响应于每次的返回操作，依次返回显示用户界面510、用户界面430、用户界面420、用户界面410和用户界面300，也就是依次弹出第一活动栈的栈顶活动，直到栈顶活动为用户界面300关联的活动。示例性地，电子设备可以执行S104所示的普通返回方法，图26所示实施例中，back stack包括更多的Activity，例如为20个Activity，从底部往顶部(即按照进入的顺序，也即按照打开的先后顺序)依次为：Activity1、Activity2、…、Activity19、Activity20，电子设备确定接收普通返回操作且不满足快速返回的触发条件时，可以弹出back stack的栈顶活动：Activity20。上述情况可以理解为是一次普通返回操作出栈一个Activity。
在一些实施例中，电子设备显示第一应用程序的第一界面时，接收第一用户操作，响应于第一用户操作，弹出第一活动栈的至少两个活动。具体地，电子设备显示第一应用程序的第一界面时，第一活动栈的栈顶活动为第一活动。电子设备响应于第一用户操作，弹出第一活动栈中第二活动之后进入的至少两个活动，显示第二界面。
在一些实施例中，第一用户操作为普通返回操作，电子设备接收第一用户操作时确定满足快速返回的触发条件，示例性地，以上图5所示的用户界面为例说明，用户界面520为第 一界面，用户界面300为第二界面。电子设备显示图5的(A)所示的用户界面520时，响应于1秒内执行的2次普通返回操作，在1秒内连续出栈了用户界面520和图5的(B)所示的用户界面510关联的Activity，响应于下1秒内再次接收的普通返回操作(确定满足快速返回的触发条件，也可理解为满足第一预设条件)，将用户界面300关联的第二活动之后入栈的多个Activity出栈，即将用户界面430、用户界面420和用户界面410关联的多个Activity出栈，可以理解为是一次返回操作(实际为第3次接收的普通返回操作)出栈3个Activity。
在另一些实施例中，第一用户操作为快速返回操作，示例性地，上图6所示过程中，用户界面520为第一界面，用户界面300为第二界面，电子设备响应于1秒内执行的2次普通返回操作(确定第二数量个第二用户操作满足第二预设条件)，在1秒内连续出栈了用户界面510和用户界面520关联的Activity，并且在显示用户界面430时显示第一提示信息434(满足第二预设条件时，显示的第一控件例如为第一提示信息434)。电子设备可以响应于作用于第一提示信息434的用户操作(即快速返回操作)，将用户界面300关联的第二活动之后入栈的多个Activity出栈，即将用户界面430、用户界面420和用户界面410关联的多个Activity出栈，可以理解为是一次快速返回操作出栈3个Activity。示例性地，上图8所示过程中，电子设备响应于作用于区域2的滑动操作(即快速返回操作)，将用户界面300关联的第二活动之后入栈的多个Activity出栈，即将用户界面520、用户界面410、用户界面430、用户界面420和用户界面410关联的多个Activity出栈，可以理解为是一次快速返回操作出栈5个Activity。其他示例的第一用户操作可参见上图10-图11、图13-图16。
示例性地，电子设备可以执行S105所示的快速返回方法，图26所示实施例中，back stack包括更多的Activity，例如为20个Activity，从底部往顶部(即按照进入的顺序，也即按照打开的先后顺序)依次为：Activity1、Activity2、…、Activity19、Activity20。第一活动为栈顶活动：Activity20，第二活动为栈底活动：Activity20。电子设备确定接收普通返回操作且满足快速返回的触发条件，或者接收快速返回操作时，可以弹出back stack的Activity20之后进入的(即之上)的Activity(即Activity2、…、Activity20)。
在一些实施例中，电子设备可以预设执行快速返回方法后第一活动栈的栈顶活动(即上述第二活动)，例如预设执行快速返回方法前第一活动栈的栈底活动为第二活动。
在另一些实施例中，电子设备可以根据Activity的类型确定执行快速返回方法后第一活动栈的栈顶活动(即上述第二活动)。假设Activity的名称包括应用程序的名称(简称包名)和具体名称(简称Activity标记)，属于同一个应用程序的Activity的包名相同，但Activity标记不同，不同类型的Activity对应的标记不同。在一些实施例中，电子设备可以记录接收特定操作的用户界面关联的Activity，例如图12所示实施例中，电子设备可以响应于作用于收藏选项424(例如第四控件为收藏选项424)的用户操作，记录用户界面420关联的Activity。在一些实施例中，记录的Activity可以为执行快速返回方法后第一活动栈的栈顶活动。示例性地，电子设备可以记录应用程序的主界面关联的Activity，以及记录接收特定操作的用户界面关联的Activity。电子设备可以根据快速返回操作的类型确定返回界面对应的Activity，具体地，电子设备可以响应于第一快速返回操作，将第一活动栈中应用程序的主界面关联的Activity之上的Activity出栈，即返回到应用程序的主界面。电子设备可以响应于第二快速返回操作，将第一活动栈中接收特定操作的用户界面关联的Activity之上的Activity出栈，即返回到接收特定操作的用户界面。
在另一些实施例中，假设电子设备运行有第一活动栈，电子设备显示第二应用程序的第三界面时，和第三界面关联的第三活动压入第一活动栈，然后，电子设备显示第一应用程序 的第二界面时，和第二界面关联的第二活动压入第一活动栈，然后，电子设备显示第一应用程序的第一界面时，和第一界面关联的第一活动压入第一活动栈。示例性地，上图19所示过程中，电子设备响应于每次的用户操作(用于打开/跳转到当前显示界面的下一级界面)，依次显示视频应用的用户界面2510、视频应用的用户界面2520、视频应用的用户界面2530、购物应用的用户界面430、购物应用的用户界面510和购物应用的用户界面520，也就是将用户界面2510、用户界面2520、用户界面2530、用户界面430、用户界面510和用户界面520压入第一活动栈。其中，购物应用的用户界面520例如为第一应用程序的第一界面(即当前显示界面)，则第一活动栈的栈顶活动为用户界面520关联的第一活动。购物应用的用户界面430例如为第一应用程序的第二界面，视频应用的用户界面2510例如为第二应用程序的第三界面。
在一些实施例中，电子设备显示第一应用程序的第一界面时，接收第一用户操作。电子设备可以响应于第一用户操作，弹出第一活动栈的至少两个活动，显示第一应用程序的第二界面，或者，电子设备可以响应于第一用户操作，弹出第一活动栈的至少两个活动，显示第二应用程序的第三界面。
在一些实施例中，第一用户操作为普通返回操作，电子设备接收第一用户操作时确定满足快速返回的触发条件，在另一些实施例中，第一用户操作为快速返回操作，具体示例和上述第一活动栈包括第一活动和第二活动的示例类似。
在一些实施例中，显示第二界面之前和显示第二界面之前，接收的第一用户操作的类型不同，例如作用区域、作用控件、操作方向、滑动距离等操作方式不同，例如图13-图14所示的第一快速返回操作和第二快速返回操作。示例性地，图20所示过程中，购物应用的用户界面520为第一应用程序的第一界面，购物应用的用户界面430为第一应用程序的第二界面，视频应用的用户界面2510为第二应用程序的第三界面。电子设备显示图20的(B)所示的用户界面520时，可以显示第六提示信息523A和第七提示信息523B(显示的第一界面中，包括的第二控件例如为第六提示信息523A，第三控件例如为第七提示信息523B)，第六提示信息523A为购物应用的图标，用于指示购物应用，第七提示信息523B为视频应用的图标，用于指示视频应用。电子设备可以响应于作用于第六提示信息523A的触摸操作，返回显示购物应用中第一个打开的用户界面，即用户界面430(即第二界面)，也就是说，电子设备可以将用户界面430关联的第二活动之后入栈的多个Activity出栈，即将用户界面520和用户界面510关联的2个Activity出栈，可以理解为是一次快速返回操作出栈2个Activity。电子设备可以响应于作用于第七提示信息523B的触摸操作，返回显示视频应用中第一个打开的用户界面，即视频应用的主界面，即用户界面2510(即第三界面)，也就是说，电子设备可以将用户界面2510关联的第三活动之后入栈的多个Activity出栈，即将用户界面520、用户界面510、用户界面430、用户界面2530、用户界面2520关联的多个Activity出栈，可以理解为是一次快速返回操作出栈5个Activity。
在一些实施例中，电子设备可以根据Activity对应的应用程序，确定执行快速返回方法后第一活动栈的栈顶活动(即上述第二活动或第三活动)。假设Activity的名称包括应用程序的名称(简称包名)和具体名称(简称Activity标记)，属于同一个应用程序的Activity的包名相同。在一些实施例中，电子设备可以识别第一活动栈中Activity的包名是否变化，可选地，电子设备可以记录包名变化后的第一个Activity，可选地，电子设备也可以记录包名变化前第一个入栈的Activity，可选地，记录的Activity可以为执行快速返回方法后第一活动栈的栈顶活动。示例性地，图19所示实施例中，电子设备显示视频应用的用户界面2530时，可 以响应于作用于购物选项2531的用户操作，显示购物应用的用户界面430，此时第一活动栈的栈顶活动的包名从视频应用的包名变为购物应用的包名，则电子设备可以记录包名变化后的第一个Activity：用户界面430关联的第二活动，也可以记录包名变化前第一个入栈的Activity：用户界面2510关联的第三活动(即第一活动栈的栈底活动)。电子设备可以根据快速返回操作的类型确定返回界面对应的Activity，具体地，电子设备可以响应于第一快速返回操作，将第一活动栈中第二活动之上的Activity出栈，即返回到购物应用的用户界面430。电子设备可以响应于第二快速返回操作，将第一活动栈中第三活动之上的Activity出栈，即返回到视频应用的用户界面2510。
在一些实施例中，电子设备可以记录第一活动栈中每个Activity出栈的时间和出栈的Activity的个数，以在确定接收普通返回操作的情况下，根据记录的信息判断是否满足快速返回的触发条件，具体示例如下所示(以下示例以预设返回界面对应的Activity为Activity1为例进行说明)：
示例一：假设电子设备接收了K次普通返回操作，K为正整数，电子设备可以响应于每次的返回操作，将第一活动栈中的顶部Activity出栈，可以理解为是执行了K个S101、S103和S104。电子设备可以记录每次Activity出栈的时间，假设记录的出栈时间为[t1,t2,…，t(K)]。然后，假设电子设备在时刻t(K+1)接收第(K+1)次普通返回操作，可以判断(t(K+1)-t(K))是否小于或等于第一预设时长。若电子设备确定(t(K+1)-t(K))小于或等于第一预设时长，则确定满足快速返回的触发条件。因此，电子设备可以响应于第(K+1)次普通返回操作，将第一活动栈中预设返回界面对应的Activity1以上的多个Activity出栈。在一些实施例中，可以理解为是执行了第(K+1)个S101和S103，以及执行了1个S105。
示例二：假设电子设备接收了K次普通返回操作，K为正整数，电子设备可以响应于每次的返回操作，将第一活动栈中的顶部Activity出栈，可以理解为是执行了K个S101、S103和S104。电子设备可以记录每次Activity出栈的时间，假设记录的出栈时间为[t1,t2,…，t(K)]。然后，电子设备可以接收第(K+1)次普通返回操作，响应于第(K+1)次普通返回操作，将第一活动栈中的顶部Activity出栈，并记录出栈时间t(K+1)。若电子设备确定(t(K+1)-t(K))小于或等于第一预设时长，则确定满足快速返回的触发条件。因此，电子设备可以响应于第(K+1)次普通返回操作，将第一活动栈中预设返回界面对应的Activity1以上的多个Activity出栈。在一些实施例中，可以理解为是执行了第(K+1)个S101和S103，以及执行了1个S105。
不限于此，在另一些示例中，电子设备确定满足快速返回的触发条件时，也可以显示提示信息(例如第一控件)，该提示信息用于用户确定是否执行快速返回操作，用户确定执行快速返回操作时，电子设备可以执行S102和S103。
在一些实施例中，S101和/或S102之前，该方法还可以包括：确定第一活动栈中Activity的数量大于或等于预设数量阈值。可以理解为是，Activity的数量大于或等于预设数量阈值的back stack可以应用本申请所示的快速返回方法。
在一些实施例中，S101和/或S102之前，该方法还可以包括：确定第一活动栈中Activity关联的用户界面的应用程序为可启用快速返回功能的应用(简称预设应用)，可选地，确定第一活动栈中任意一个Activity关联的用户界面的应用程序为预设应用，可选地，确定执行快速返回方法后第一活动栈的栈顶活动关联的用户界面的应用程序为预设应用。可选地，假设Activity的名称包括应用程序的名称(简称包名)和具体名称(简称Activity标记)，属于同一个应用程序的Activity的包名相同，但Activity标记不同。则确定预设应用时，电子设备可以判断Activity的包名是否为预设应用的包名。可以理解为是，电子设备上的预设应用可以 应用本申请所示的快速返回方法。可选地，预设应用可以为电子设备上部分或全部的应用。
上图26中任意至少一项为可选的步骤，例如仅包括S102和S105，或者仅包括S101和S104，或者不包括S102。不限于此，还可以是包括S101和S103，并且该方法还可以包括：在确定电子设备满足快速返回的触发条件的情况下，即S103的判断结果为是的情况下，电子设备可以显示提示信息。或者，还可以是在S101和/或S102之前，该方法还可以包括：电子设备显示提示信息。提示信息用于指示快速返回操作。提示信息的示例可参见上图6、图10-图11、图15-图18、图20。
可以理解地，图26所示方法的示例可参见上图3-图25所示实施例。
本申请中，若用户想要返回到预设返回界面，用户只需执行少量的普通返回操作，或执行一次快速返回操作，就能返回到预设返回界面，具体示例可参见下图27-图28。
以下实施例以back stack包括20个Activity，预设返回界面对应Activity为back stack底部的Activity1为例进行说明。
请参见图27，图27示例性示出一种Activity出栈的示意图。
如图27所示，假设快速返回的触发条件为：接收5次普通返回操作的时段的时长小于或等于3秒。当back stack包括20个Activity时，电子设备可以在2秒内依次接收了用户4次的普通返回操作，响应于每次的普通返回操作，将back stack的顶部Activity出栈，即从当前显示界面返回到上一级界面。此时，back stack的顶部Activity为16，电子设备可以在1秒内接收用户第五次的普通返回操作。电子设备确定第4次普通返回操作和第5次普通返回操作的接收时刻的差值小于或等于1秒，即确定满足快速返回的触发条件。电子设备可以响应于第5次的普通返回操作，将back stack中预设返回界面对应的Activity1以上的多个Activity出栈。Activity1以上的多个Activity即为Activity2、Activity3、…、Activity15、Activity16这15个Activity，此时，back stack的顶部Activity为Activity1，电子设备可以显示预设返回界面。用户仅需执行5次普通返回操作，即可达到执行19次普通返回操作才能返回显示的用户界面，操作简单。
在一些实施例中，电子设备可以响应于一次快速返回操作，将back stack中预设返回界面对应的Activity以上的多个Activity按照先进后出的原则依次出栈，该方案可以称为第一出栈方案。在另一些实施例中，电子设备可以响应于一次快速返回操作，先将back stack中预设返回界面对应的Activity和顶部Activity之间的多个Activity出栈，然后再将顶部Activity出栈，该出栈方案可以称为第二出栈方案，具体示例可参见下图28。
请参见图28，图28示例性示出又一种Activity出栈的示意图。
如图28所示，当back stack包括20个Activity时，电子设备可以响应于用户的快速返回操作，将back stack中预设返回界面对应的Activity1和顶部Activity(即Activity20)之间的18个Activity出栈，在一些实施例中，Activity19、Activity18、…、Activity3、Activity2这18个Activity按照先进后出的原则依次出栈。在这个过程中，back stack的顶部Activity保持为Activity20，即电子设备显示的用户界面保持为Activity20对应的用户界面。然后，电子设备可以继续将Activity20出栈，此时，back stack的顶部Activity为Activity1，电子设备可以显示预设返回界面。
不限于图28所示示例，在具体实现中，也可以是Activity19、Activity18、…、Activity3、Activity2这18个Activity按照后进先出的原则依次出栈，还可以是按照任意顺序出栈，本申请对此不作限定。
不限于图28所示示例，在具体实现中，电子设备也可以响应于用户的普通返回操作(且 确定满足快速返回的触发条件)，将back stack中预设返回界面对应的Activity和顶部Activity之间的多个Activity出栈，例如图27中，当back stack的顶部Activity为16时，电子设备可以响应于用户第五次的普通返回操作，将back stack中预设返回界面对应的Activity1和顶部Activity(即Activity16)之间的14个Activity出栈，然后再将Activity16出栈。
在一些实施例中，在Android系统中，当用户进入、退出、回到应用(也可以理解为是打开、退出、返回用户界面)时，用户界面对应的Activity经历了生命周期中的不同状态，Android系统调用了一系列生命周期中的方法。可以理解为是每个Activity存在生命周期，具体示例可参见下图29。
请参见图29，图29示例性示出一种Activity的生命周期的示意图。
如图29所示，生命周期的整个过程可以理解为是从创建方法onCreated()开始，到销毁方法onDestroy()结束，用户可以见到Activity，也可以理解为是用户可以见到该Activity对应的用户界面，是从开始方法onStart()到停止方法onStop()之间。用户可以和Activity交互，也可以理解为是用户可以和该Activity对应的用户界面交互，是从恢复方法onResume()到暂停方法onPause()。除此以外，生命周期还可以包括重启方法onRestart()，也就是说，生命周期可以包括七种方法，说明示例如下所示：
创建方法onCreated()：在Activity被创建时调用，通常做一些初始化设置。
开始方法onStart()：在Activity准备显示在屏幕前调用，调用后Activity处于可见状态。
恢复方法onResume()：在Activity获取焦点开始和用户交互时调用。
暂停方法onPause()：在当前Activity被其他Activity部分覆盖或锁屏时调用。
停止方法onStop()：在Activity对用户处于不可见状态时调用。
销毁方法onDestroy()：在Activity即将被销毁时调用。
重启方法onRestart()：在Activity从停止(Stopped)状态再次启动时调用。
如图29所示，Activity在不同的方法调用执行后处于不同的状态，生命周期可以包括五中状态，说明示例如下所示：
创建(Created)状态：方法onCreated()执行后Activity所处的状态，Activity处于当前状态时对用户不可见且不可与用户交互。
开始(Started)状态：方法onStart()执行后Activity所处的状态，Activity处于当前状态时对用户可见但不可与用户交互。其中，当Activity处于Created状态时，方法onStart()执行后Activity处于Started状态。当Activity处于Stopped状态时，方法onRestart()、onStart()依次执行后Activity处于Started状态。
恢复(Resumed)状态：也可称为运行(running)状态。方法onResume()执行后Activity所处的状态，Activity处于当前状态时对用户可见且可以与用户交互。其中，方法onResume()执行前，Activity可以处于Started状态或Paused状态。
暂停(Paused)状态：方法onPause()执行后Activity所处的状态，Activity处于当前状态时对用户可见但不可与用户交互。
停止(Stopped)状态：方法onStop()执行后Activity所处的状态，Activity处于当前状态时对用户不可见且不可与用户交互。
销毁(Destroyed)状态：方法onDestroy()执行后Activity所处的状态，Activity处于当前状态时对用户不可见且不可与用户交互。
以下实施例以针对不同的Activity调用生命周期的方法时，方法携带Activity的标识为例进行说明，本申请以Activity(i)为Activity的标识为例进行说明，i为正整数。例如，假设图1 中，针对Activity1调用的生命周期的方法可以表示为：onCreated(Activity1)、onStart(Activity1)、onResume(Activity1)、onPause(Activity1)、onStop(Activity1)、onDestroy(Activity1)、onRestart(Activity1)。
示例性地，在上图1中，Activity1第一次启动，压入back stack时，可以针对Activity1依次调用方法onCreated(Activity1)、onStart(Activity1)、onResume(Activity1)，则Activity1的状态可以依次为Created、Started、Resumed。也就是说，当Activity1为back stack的顶部Activity时，状态为Resumed，对用户可见且可以与用户交互。而当Activity2第一次启动，压入back stack时，可以针对Activity1和Activity2依次调用方法onPause(Activity1)、onCreated(Activity2)、onStart(Activity2)、onResume(Activity2)、onStop(Activity1)。此时，Activity2为back stack的顶部Activity，状态为Resumed，对用户可见且可以与用户交互，而Activity1状态为Stopped，对用户不可见且不可与用户交互。然后，当用户执行返回操作，Activity2出栈时，可以针对Activity1和Activity2依次调用方法onPause(Activity2)、onRestart(Activity1)、onStart(Activity1)、onResume(Activity1)、onStop(Activity2)、onDestroy(Activity2)。Activity2被销毁，Activity1重新变为back stack的顶部Activity。
在一些实施例中，采用第一出栈方案时，电子设备可以响应于用户的快速返回操作，将back stack中预设返回界面对应的Activity以上的多个Activity按照先进后出的原则依次出栈，即将Activity20、Activity19、…、Activity3、Activity2依次出栈，以使Activity1为顶部Activity，Activity1对用户可见且可以与用户交互。以Activity20出栈为例，可以针对Activity20和Activity19依次调用方法onPause(Activity20)、onRestart(Activity19)、onStart(Activity19)、onResume(Activity19)、onStop(Activity20)、onDestroy(Activity20)，而这样的过程还需执行18次。因此，采用第一出栈方案时，电子设备需调用(19×6)次生命周期的方法，才能使Activity1为顶部Activity。
在一些实施例中，如图28所示，采用第二出栈方案时，电子设备可以响应于用户的快速返回操作，将back stack中预设返回界面对应的Activity1和顶部Activity(即Activity20)之间的18个Activity出栈，在一些实施例中，Activity19、Activity18、…、Activity3、Activity2这18个Activity按照先进后出的原则依次出栈，电子设备可以依次调用方法onDestroy(Activity19)、onDestroy(Activity18)、…、onDestroy(Activity3)、onDestroy(Activity2)，共调用了18次生命周期的方法。在这个过程中，back stack的顶部Activity保持为Activity20，即电子设备显示的用户界面保持为Activity20对应的用户界面。然后，电子设备可以继续将Activity20出栈，电子设备可以针对Activity20和Activity1依次调用方法onPause(Activity20)、onRestart(Activity1)、onStart(Activity1)、onResume(Activity1)、onStop(Activity20)、onDestroy(Activity20)，共调用了6次生命周期的方法。因此，采用第二出栈方案时，电子设备需调用(18+6)次生命周期的方法，就可以使Activity1为顶部Activity。
可以理解地，(18+6)远小于(19×6)，电子设备采用第二出栈方案时所耗费的功耗远远小于采用第一出栈方案时所耗费的功耗，例如减少了90％的功耗。并且，电子设备采用第一出栈方案时，用户执行一次快速返回操作，电子设备显示的用户界面会从Activity20对应的用户界面，依次跳转到Activity1对应的预设返回界面，即电子设备实际显示了20个用户界面(加载了20个用户界面所需的图片、视频等数据)，但由于跳转速度过快(跳转时间较短)，用户可见的用户界面可能出现闪烁、白屏、卡顿等问题。而电子设备采用第二出栈方案时，用户执行一次快速返回操作，电子设备显示的用户界面会直接从Activity20对应的用户界面跳转到Activity1对应的预设返回界面，即电子设备实际显示了2个用户界面，性能流畅，用 户体验感更好。
示例性地，上图8所示实施例中，电子设备显示用户界面520时，用户界面520和第一活动栈的栈顶活动关联，假设用户界面300和第一活动栈的栈底活动关联，第一活动栈包括的Activity按照从底部往顶部的顺序(即进入的先后顺序)依次为用户界面300、用户界面410、用户界面420、用户界面430、用户界面510和用户界面520关联的Activity。电子设备可以响应于用户的快速返回操作，弹出栈顶活动和栈底活动之间的多个Activity，即对栈顶活动和栈底活动之间的多个Activity分别执行方法onDestroy()，例如依次调用方法onDestroy(用户界面510关联的Activity)，onDestroy(用户界面430关联的Activity)，onDestroy(用户界面420关联的Activity)，onDestroy(用户界面410关联的Activity)。然后，电子设备可以弹出栈顶活动，显示用户界面300，即依次调用方法onPause(用户界面520关联的活动)、onRestart(用户界面300关联的活动)、onStart((用户界面300关联的活动)、onResume((用户界面300关联的活动)、onStop(用户界面520关联的活动)、onDestroy(用户界面520关联的活动)。其他快速返回的用户界面的示例类似，不再赘述。
不限于上述示例，也可以是Activity19、Activity18、…、Activity3、Activity2这18个Activity按照后进先出的原则依次出栈，电子设备可以依次调用方法onDestroy(Activity2)、onDestroy(Activity3)、…、onDestroy(Activity18)、onDestroy(Activity19)，还可以是按照任意顺序出栈，本申请对此不作限定。
快速返回方法返回的预设返回界面对应的Activity和Task的顶部Activity之间也可以仅包括一个Activity。
以上实施例以快速返回方法返回的预设返回界面对应back stack中位于底部的Activity1为例进行说明。在具体实现中，快速返回方法返回的预设返回界面对应的back stack中除顶部Activity外的任意一个Activity，例如Activity(2)、Activity(5)等。
本申请中的活动(Activity)可以理解为是一个用户界面，例如显示在整个显示屏上的用户界面，或者显示在显示屏上除状态栏以外的区域的用户界面等。用户界面可以是电子设备响应于接收的用户操作显示的界面，例如上图4所示实施例中，电子设备显示用户界面300时，可以响应于作用于夏季服饰320A的触摸操作，跳转显示用户界面400。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，该流程可以由计算机程序来计算机程序相关的硬件完成，该计算机程序可存储于计算机可读取存储介质中，该计算机程序在执行时，可包括如上述各方法实施例的流程。而前述的存储介质包括：只读存储器(read-only memory，ROM)或随机存取存储器(random access memory，RAM)、磁碟或者光盘等各种可存储计算机程序代码的介质。
