  • Activity is an application component that provides a screen on which the user can Interact with an electronic device on a screen to complete a task.

  • Each Activity can respond to onCreate(), onStart(), onResume(), onPause(), onStop( when switching between foreground and background. ), onDestory() and other function calls make each Activity in a different running state by calling different functions.
  • onCreate() indicates that the Activity is being created, which is the first method of the life cycle. In this method, you can do some initialization work, such as calling setContentView to load page layout resources, initializing the data required by the Activity, etc.
  • onStart() indicates that the Activity is being started and is about to start. At this time, the Activity is already visible, but it has not yet appeared in the foreground and cannot interact with the user yet. At this time, it can actually be understood that the Activity has been displayed, but we cannot see it yet.
  • onResume() means that the Activity is already visible, appears in the foreground and starts to be active. At this time, the Activity must be at the top of the return stack and in a running state.
  • onStart and onResume indicate that the Activity is already visible, but the Activity is still in the background during onStart, and the Activity is only displayed in the foreground during onResume.
  • onPause() indicates that the Activity is being paused. You can do some work such as storing data, stopping animations, etc., but it cannot be too time-consuming because it will affect the display of the new Activity.
  • onPause() must be executed first before the new Activity's onResume will be executed.
  • implement. onStop() indicates that the Activity is about to stop, and you can do some heavyweight recycling work, which should not be too time-consuming.
  • onDestory() indicates that the Activity is about to be destroyed. This is the last callback of the Activity life cycle.
  • onRestart() indicates that the Activity is being restarted. Under normal circumstances, onRestart() will be called when the current Activity changes from invisible to visible again. This situation is usually caused by user behavior. For example, the user presses the Home button to switch to the desktop or the user opens a new Activity. At this time, the current Activity will be suspended, that is, onPause() and onStop() are executed. This situation will occur when the user returns to this Activity.
  • onStop() In the above Activity life cycle, the main difference between onStop() and onPause() is that if the new Activity started is a dialog-type Activity, that is, when the new Activity does not completely cover the currently displayed Activity, onPause() will be called function without calling the onStop() function. Among them, after calling the onPause() function, the suspended Activity will still remain active (that is, keep all states, member information, and remain connected to the window manager), and will only be forcibly terminated when the system memory is extremely low. ; After calling the onStop() function, when memory is needed elsewhere, the stopped Activity may be recycled by the system. That is to say, when there is insufficient memory, the system will give priority to recycling stopped activities.

Therefore, when receiving the first trigger operation, the preset pause function (ie, onPause() function) will be called to control the Activity corresponding to the foreground application to enter the pause state. In other words, during the process of displaying recent tasks, the life cycle of the foreground application will only reach the paused state, but will not enter the next stop state.

在相关技术中，从当前应用内进入近期任务，背景都展示桌面的背景图片，当前应用的应用界面缩放为近期任务的一张Task任务卡片。如图1所示，设置应用程序为当前应用，界面101即为当前应用的应用界面，图2示出了从设置应用程序进入近期任务的显示界面，在近期任务的显示界面中，界面201为以桌面的背景图片作为背景界面，以设置应用程序的缩放界面202为近期任务中的第一张任务卡片，线上商城应用程序的缩放界面203为第二张任务卡片，其中，缩放界面202和缩放界面203均叠加显示在背景界面201。用户想要切换应用，需要通过滑动操作才能切换。当用户进入近期任务无操作时退出近期任务或者打开原来的应用时，当前应用会发生重新启动，影响用户的使用体验。
发明人提出一种界面显示方法、装置、电子设备及存储介质，响应于第一触发操作，在前台应用程序的应用界面的部分区域中叠加显示目标应用程序对应的任务标识。下面对本申请实施例提供的界面显示方法进行详细描述。
请参照图3，图3为本申请一实施例提供的一种界面显示方法的流程示意图。下面将结合图3对本申请实施例提供的界面显示方法进行详细阐述。该界面显示方法可以包括以下步骤：
步骤S110：显示当前处于前台运行状态的前台应用程序的应用界面。
在本实施例中，前台应用程序可以理解为在电子设备的屏幕中，可见的且用户能进行交互操作的应用程序，例如，正在运行的游戏应用程序、即时通信应用程序、购物应用程序以及设置应用程序等；对应地，第一界面即为前台应用程序当前显示的应用界面。仍以前台应用程序为设置应用程序为例，请参阅图1，图1示出了设置应用程序的应用界面。
其中，电子设备包括但不限于智能手机、平板电脑、电子书阅读器、膝上型便携计算机、车载电脑、台式计算机、智能电视机、可穿戴设备等等。
步骤S120：响应于第一触发操作，在所述应用界面的部分区域中叠加显示目标应用程序对应的任务标识，所述目标应用程序包括接收所述第一触发操作之前处于后台运行状态的至少部分后台应用程序。
基于此，用户若想要查看后台应用程序、切换前台应用程序或者清除后台应用程序，可以输入第一触发操作，对应地，电子设备则响应于第一触发操作，并展示近期任务，展示近期任务可以具体通过在应用界面的部分区域中叠加显示目标应用程序对应的任务标识的方式来进行展示。其中，任务标识至少包括应用程序的历史显示界面的界面截图、应用图标、应用名称、历史显示界面的内容信息中的一种或多种。如此，用户可以根据任务标识，选择其想要查看后台应用程序或者待清除的后台应用程序，提高了操作的便捷性。
其中，近期任务可以理解为在指定时间段内启动过的应用程序，指定时间段可以是当前时间之前且与当前时间相距指定时长的时间段，该指定时长可以是电子设备默认的时长，例如2小时、3小时等；当然，用户也可以根据实际需求对该默认时长进行调整，例如，电子设备可以提供相应的时长设置界面，用户可以在该时长设置界面内对指定时长进行调整。对应地，上述目标应用程序即为响应第一触发操作之前的指定时间段内，启动过且处于后台运行状态的至少部分后台应用程序。也就是说，电子设备可以响应于第一触发操作，展示近期任务，即在应用界面的部分区域中叠加显示指定时间段内启动过且处于后台运行状态的后台应用程序对应的任务标识。
其中，由于在响应第一触发操作之后，前台应用程序也会进入后台运行状态，因此，上述目标应用程序仅包括接收第一触发操作之前的后台应用程序，具体地，在确定目标应用程序时，可以调用loadTasksInBackground方法，过滤掉前台应用程序，仅确定第一触发操作之前的后台应用程序作为目标应用程序。在实际应用中，由于电子设备的屏幕尺寸的限制，当后台应用程序的数量过多时，电子设备无法一次性将所有的后台应用程序的任务标识同时显示，因此，上述目标应用程序包括至少部分后台应用程序，当然，在后台应用程序数量较少时，目标应用程序也可以包括所有的后台应用程序。
可选地，上述第一触发操作包括但不限于：滑动操作、或者点击操作、或者长按操作等。其中，响应于上述滑动操作的区域可以是某个控件、也可以是屏幕中或者边缘指定的某一区域，滑动方向可以是从左到右、从右到左、从上到下、从下到上、45度方向或者30度方向等。其中，控件可以指提供或实现用户界面功能的组件，组件是对数据和方法的封装，组件可以有自己的属性和方法。在实际应用中，可以在界面的下边缘、上边缘、左边缘、或者右边缘显示所述控件。当然，也可以在界面的中间区域等任意位置显示上述控件，本申请实施例对于上述控件在界面中的具体位置不加以限制。点击操作可以是单击操作、或者双击操作等。响应单击操作的区域可以是某个控件、也可以是屏幕中、边缘指定的某一区域或者是物理按键，例如“home”按键。长按操作可以指对屏幕的操作时长超过预设时长的操作，预设时长可以是预先设置的时长，例如2秒等。响应长按操作的区域可以是某个控件、也可以是屏幕中或者边缘指定的某一区域、或者还可以是物理按键，例如“home”按键，本实施例对此不作限制。
请参阅图4，以任务标识为应用程序的历史显示界面，前台应用程序为设置应用程序为例，图4示出了设置应用程序的应用界面401的部分区域中叠加显示目标应用程序对应的历史显示界面的界面截图，其中，叠加显示的界面截图包括线上商城应用功能程序的历史显示界面402和即时通信应用程序的历史聊天界面403。也可以理解为，以应用界面401作为近期任务的显示背景图片，将近期任务中的目标应用程序的历史显示界面的界面截图进行缩小后，以可滑动选择的任务卡片的形式叠加显示在应用界面401上。
在一些实施方式中，请参阅图5，步骤S120可以包括步骤S121至步骤S122中的内容：
步骤S121：响应于所述第一触发操作，调用预设暂停函数控制所述前台应用程序进入暂停状态。
在本实施例中，以电子设备为安卓(Android)系统为例，对于Android程序来说，每个显示界面都是一个单独的Activity，Activity是一个应用程序组件，提供一个屏幕，用户可以在该屏幕上与电子设备进行交互来完成某项任务。请参阅图6，图6示出了Android系统中Activity的生命周期的示意图，其中，每个Activity在前后台切换时可以对onCreate()、onStart()、onResume()、onPause()、onStop()、onDestory()等函数调用，通过调用不同的函数，使得每个Activity处于不同的运行状态。
其中，onCreate()表示Activity正在被创建，这是生命周期的第一个方法。在这个方法中，可以做一些初始化工作，比如调用setContentView去加载页面布局资源，初始化Activity所需数据等。onStart()表示Activity正在被启动，即将开始，这时Activity已经可见，但是还没有出现在前台，还无法和用户交互。这个时候其实可以理解为Activity已经显示出来了，但是我们还看不到。onResume()表示Activity已经可见，出现在前台并且开始活动，此时的Activity一定位于返回栈的栈顶，并且处于运行状态。onStart和onResume都表示Activity已经可见，但是onStart的时候Activity还在后台，onResume的时候Activity才显示到前台。onPause()表示Activity正在暂停，可以做一些存储数据、停止动画等工作，但是不能太耗时，因为会影响到新的Activity的显示，onPause()必须先执行完，新的Acitivty的onResume才会执行。onStop()表示Activity即将停止，可以做一些稍微重量级的回收工作，同样不能太耗时。onDestory()表示Activity即将被销毁，这是Activity生命周期的最后一个回调，在这个方法中，可以做一些回收工作和最终的资源释放。onRestart()表示Activity正在重新启动。一般情况下，在当前的Activity从不可见重新变成可见状态时，onRestart()就会被调用。这种情形一般时用户行为所致，比如用户按Home键切换到桌面或者用户打开了一个新的Activity，这个时候当前的Activity就会暂停，也就是onPause()和onStop()被执行了，该用户又回到这个Activity，就会出现这种情况。
在上述Activity生命周期中，onStop()和onPause()的主要区别在于，如果启动的新Activity是一个对话框式的Activity，即新Activity没有完全覆盖当前显示的Activity时，则会调用onPause()函数，而不会调用onStop()函数。其中，在调用onPause()函数后，处于暂停状态的Activity依然保持活力(即保持所有的状态，成员信息，和窗口管理器保持连接)，仅会在系统内存极端低下的时候将被强行终止掉；而在调用onStop()函数后，当其他地方需要内存时，处于停止状态的Activity有可能会被系统回收。也就是说，当内存不足时，系统会优先回收处于停止状态的Activity。
基于此，由于本实施例中电子设备在展示近期任务时，删除AppToOverviewAnimationProvider窗口动画，即不不执行针对前台应用程序的窗口缩放动画，直接以前台应用程序的应用界面始终作为近期任务的背景进行显示，即始终可见的状态。因此，在接收到第一触发操作时，会调用预设暂停函数(即onPause()函数)控制前台应用程序对应的Activity进入暂停状态。也就是说，在展示近期任务的过程中，前台应用程序的生命周期仅会走到暂停状态，而不会进入到下一步的停止状态，
步骤S122：在所述应用界面的部分区域中叠加显示目标应用程序对应的任务标识。
进一步地，在暂停前台应用程序对应的Activity之后，可以创建近期任务对应的新的Activity，上述目标应用程序对应的任务标识即为新的Activity。具体地，系统则会自动调用onCreate()函数创建新的Activity，并调用OnStart()函数启动新的Activity，最后，调用OnResume()函数使得新的Activity出现在前台运行，处于可见且可交互状态。
具体地，从前台应用程序进入近期任务的函数调用流程可以表示如下：
ApplicationActivity1.onPause()-＞LauncherActivity.onCreate()-＞Launchertivity.OnStart()-＞Launchertivity.OnResume()
其中，ApplicationActivity1为前台应用程序的应用界面，LauncherActivity为新界面。
在一些实施方式中，在步骤S122之后，电子设备可以响应于第六触发操作，调用预设恢复函数控制所述暂停状态的前台应用程序恢复前台运行状态，并将当前显示界面切换为所述前台应用程序的显示界面。其中，前台应用程序的显示界面为前台应用程序从暂停状态恢复至前台运行状态时，根据当前时刻的实际待显示信息确定的实时显示界面；第六触发操作可以是点击前台应用程序的应用界面的任一可见区域，即可实现从近期任务返回至前台应用程序，操作简便快捷，避免了相关技术中用户在滑动了近期任务的任务卡片后，需要再滑动回前台应用程序对应的任务卡片处，再点击前台应用程序对应的任务卡片才能返回至前台应用程序的繁琐操作。当然，第六触发操作也可以是滑动操作或长按操作等，具体的操作方式可以参阅前述对第一触发操作的描述，在此不再赘述。
其中，从近期任务返回至前台应用程序的函数调用流程可以表示如下：
LauncherActivity.onPause()-＞ApplicationActivity1.OnResume()-＞LauncherActivity.onStop()
其中，LauncherActivity为近期任务的显示界面，ApplicationActivity1为新界面，即前台应用程序的应用界面。由此可见，用户进入近期任务无操作时返回至前台应用程序时，直接调用OnResume()函数，及时控制前台应用程序恢复前台运行状态，并将当前显示界面切换为前台应用程序的实时显示界面，即前台应用程序不会重新启动，进而实现用户在进入退出近期任务对当前正在使用的前台应用程序无感，提高了用户使用体验。
而在相关技术中，例如图2中的近期任务展示界面中，当用户向右滑动后，前台应用程序的应用界面则会变为不可见，即此时，前台应用程序则会调用onstop()函数，若用户用进入近期任务无操作时返回至前台应用程序时，则会调用onRestart()函数、onstart()函数以及OnResume()函数，相当于重启了前台应用程序，导致用户从近期任务返回至前台应用程序时，无法查看到在进入近期任务前该前台应用程序的应用界面。例如，若用户在前台应用程序填写个人信息，需要通过近期任务中查看网上银行应用程序中的银行卡号码，再返回至前台应用程序进行填写，相关技术中的近期任务显示方式，则会导致前台应用程序重新启动，即用户在从近期任务返回至前台应用程序时，又需要重新填写进入近期任务前已填写过的个人信息，大大降低了用户体验。由此可见，本实施例的近期任务的显示方式相较于现有技术中的近期任务的显示方式，对用户操作来说更为友好和便捷。
在另一些实施方式中，在步骤S122之后，可以响应于程序切换操作，将当前显示界面切换为所述程序切换操作选择的任务标识对应的应用程序的显示界面；检测到所述应用界面处于被完全覆盖的状态，调用预设停止函数控制所述前台应用程序进入停止状态。也就是说，用户可以通过程序切换操作，从应用界面的部分区域中叠加显示目标应用程序对应的任务标识中，任选一个任务标识，对应地，电子设备则将当前显示界面切换为程序切换操作选择的任务标识对应的应用程序的显示界面。可以通俗地理解为，用户将近期任务中的任一后台应用程序切换至前台运行时，当前应用程序的应用界面才会被切换至前台运行的后台应用程序的应用界面完全覆盖，此时，才会调用预设停止函数控制前台应用程序进入停止状态。具体地，从近期任务进入其他后台应用的函数调用流程可以表示如下：
LauncherActivity.onPause()-＞ApplicationActivity2.onRestart()-＞ApplicationActivity2.Start()-＞Applicatio nActivity2.OnResume()-＞LauncherActivity.onStop()
其中，LauncherActivity为近期任务的显示界面，Applic ationActivity2为目标应用程序中的任一应用程序。
基于此，请参阅图7，图7示出了本实施例中前台应用程序在进入近期任务时的可见性以及生命周 期变化的流程示意图。前台应用程序在近期任务的展示过程中，一直处于可见的前台状态，使得前台应用程序进会处于暂停状态，而不会进入停止状态导致系统直接释放资源，进而使得用户在从前台应用程序进入到近期任务以及从近期任务返回至前台应用程序的操作变得无感。同时，也能避免前台应用程序可能存在自身逻辑问题，在处于停止状态时，调用destroy()函数销毁掉自身等问题的发生。再者，由于前台应用程序的应用界面始终是作为近期任务的背景图片显示，而不是同其他后台应用程序一样以任务卡片的形式展示，避免了因三方开发者不规范操作，例如错误配置和使用ExcludeFormRecents属性，导致的近期任务中不显示前台应用程序的任务卡片，用户无法从近期任务中返回至前台应用程序等问题的发生。
在本实施例中，显示当前处于前台运行状态的前台应用程序的应用界面；响应于用于触发展示近期任务的第一触发操作，在当前的前台应用程序的应用界面的部分区域中叠加显示目标应用程序对应的任务标识，其中，目标应用程序包括响应第一触发操作之前处于后台运行状态的至少部分后台应用程序。也就是说，前台应用程序在近期任务的展示过程中，一直处于可见的前台状态，使得前台应用程序处于暂停状态，而不会进入停止状态导致系统直接释放资源，以及重新返回至前台应用程序时不会发生程序重启，进而使得用户在从前台应用程序进入到近期任务以及从近期任务返回至前台应用程序的操作变得无感；同时，将目标应用程序对应的应用标识叠加显示在前台应用程序的应用界面上，也更方便用户从近期任务退出并返回至前台应用程序的操作，减少了从近期任务返回至前台应用程序的繁琐操作，提高了用户体验。
请参照图8，图8为本申请另一实施例提供的一种界面显示方法的流程示意图。下面将结合图8对本申请实施例提供的界面显示方法进行详细阐述。该界面显示方法可以包括以下步骤：
步骤S210：显示当前处于前台运行状态的前台应用程序的应用界面。
在本实施例中，步骤S210的具体实施方式可以参阅前述实施方式中的内容，在此不再赘述。
步骤S220：响应于第一触发操作，获取所述多个后台应用程序中每个后台应用程序进入后台运行时的时间信息，得到每个后台应用程序对应的第一时间。
在本实施例中，响应第一触发操作之前处于后台运行状态的后台应用程序的数量一般为多个，同时，电子设备的屏幕大小有限，可能无法同时显示所有的后台应用程序的任务标识。考虑到用户进入近期任务一般是要进行应用切换，而离当前时刻越近的后台应用程序被用户选择作为应用切换的几率越大。因此，可以获取每个后台应用程序进入后台运行时的时间信息，作为每个后台应用程序对应的第一时间。进而，可以根据第一时间确定每个后台应用程序的显示顺序，更便于用户在近期任务中进行应用切换。
其中，多个后台应用程序可以是距离当前时刻之前的指定时长内启动过的处于后台运行状态的应用程序，也可以是当前时刻之前所有的启动过的处于后台运行状态的应用程序，本实施例对此不作限制。
步骤S230：获取所述每个后台应用程序对应的第一时间距离当前时刻的时长，得到所述每个后台应用程序对应的第一时长。
步骤S240：基于所述第一时长的从小到大的顺序，对所述多个后台应用程序进行排序，得到所述第一显示顺序。
其中，第一时长越小，表征其对应的后台应用程序上一次被使用的时刻距离当前时刻最近，被用户选作用于切换前台应用程序的几率越大。
步骤S250：基于多个后台应用程序对应的第一显示顺序，获取所述第一显示顺序中前N个后台应运用程序对应的任务标识，所述N为正整数，所述第一显示顺序是基于每个后台应用程序进入后台运行时的时间确定得到。
进一步地，在确定出第一显示顺序之后，电子设备可以获取第一显示顺序中前N个后台应运用程序对应的任务标识，其中，N可以是电子设备的系统默认的数值，例如，4或5等；当然，也可以由用户根据自身实际需求，对该数值进行调整，本实施例对此不作限制。
在一些实施方式中，也可以先判断多个后台应用程序的数量是否大于N的数值，若大于，执行步骤S250的内容；若不大于，则直接按照第一显示顺序，将多个后台应运用程序对应的任务标识，叠加显示在所述应用界面的部分区域。
步骤S260：按照所述第一显示顺序，将所述前N个后台应用程序对应的任务标识，叠加显示在所述应用界面的部分区域。
在一些实施方式中，任务标识可以包括应用程序的历史显示界面的界面截图以及应用图标，将每个后台应用程序对应的历史显示界面的界面截图按照预设缩小参数进行缩小，得到每个后台应用程序对应的缩略截图；再根据第一显示顺序，将前N个后台应用程序对应的缩略截图按照预设方向叠加显示在应用界面的第一部分区域，并且，将前K个后台应用程序的应用图标也按照预设方向叠加显示在应用界面的第二部分区域，其中，第二部分区域为除第一部分区域之外的其他区域，K的取值大于或等于N。其中，第一部分区域以及第二部分区域可以是电子设备默认的区域，当然，也可以由用户根据自身的查看需求，对第一部分区域以及第二部分区域的显示位置进行调整。预设方向可以是从左至右、从右至左、从上至下、从下至上等方向，本实施例对此不作限制。如此，用户可以通过缩略截图直观地获知到后台应用程序的历史显示界面中的显示内容，以及通过任务图标更为简洁直观地告知用户当前存在哪些后台应用程序。
示例性地，请参阅图9，图9示出了根据第一显示顺序，将N个后台应用程序的缩略截图901按照从右至左的方向叠加显示在设置应用程序的应用界面903的第一部分区域，以及K个后台应用程序的应用图标902叠加显示在设置应用程序的应用界面903的第二部分区域。其中，N个后台应用程序包括线上商城应用程序以及即时通信应用程序，K个后台应用程序的应用图标包括线上商城应用程序、即时通信应用程序、浏览器应用程序以及通讯录应用程序的应用图标。
在本实施例中，根据基于每个后台应用程序进入后台运行时的时间确定得到第一显示顺序，将多个后台应用程序中的每个后台应用程序对应的任务标识，依次叠加显示于应用界面的部分区域，更便于用户在近期任务中进行应用切换。并且，在显示近期任务时，前台应用程序的应用界面始终可见，避免了在近期任务中前台应用程序被停止，导致从近期任务返回至前台应用程序时发生应用重启等问题的发生，使得用户从近期任务返回至前台应用程序的操作变得无感，提高了用户体验。
请参照图10，图10为本申请又一实施例提供的一种界面显示方法的流程示意图。下面将结合图10对本申请实施例提供的界面显示方法进行详细阐述。该界面显示方法可以包括以下步骤：
步骤S310：显示当前处于前台运行状态的前台应用程序的应用界面。
步骤S320：响应于第一触发操作，基于多个后台应用程序对应的第一显示顺序，获取所述第一显示 顺序中前N个后台应运用程序对应的任务标识，所述N为正整数，所述第一显示顺序是基于每个后台应用程序进入后台运行时的时间确定得到。
步骤S330：按照所述第一显示顺序，将所述前N个后台应运用程序对应的任务标识，叠加显示在所述应用界面的部分区域。
在本实施例中，步骤S310至步骤S330的具体实施方式可以参阅前述实施方式中的内容，在此不再赘述。
步骤S340：响应于针对指定应用程序的第二触发操作，停止运行所述指定应用程序，所述指定应用程序为所述目标应用程序中的任一应用程序。
在实际应用中，用户触发展示近期任务的目的是为了结束部分后台应用程序的后台运行，对应地，电子设备可以响应于针对指定应用程序的第二触发操作，停止运行指定应用程序，即结束指定应用程序的后台运行。其中，第二触发操作，可以是针对指定应用程序进行长按操作、双击操作、滑动操作等，操作的具体内容可以参阅前述实施例中的内容，在此不再赘述。示例性地，以第二触发操作为滑动操作为例，请参阅图11，图11中包括前台应用程序的应用界面111、线上商城应用程序的任务标识112以及即时通信应用程序的任务标识113，用户按住线上商城应用程序的任务标识112向上滑动，即可结束线上商城应用程序的后台运行。
步骤S350：获取当前所述电子设备的设备参数。
可以理解地，用户结束后台应用程序的后台运行，可能是因为后台应用程序耗电量过大，导致电子设备掉电过快；也可能是因为后台应用程序的处理器占用率过大，导致当前的前台应用程序运行卡顿；还可能是因为后台应用程序的流量消耗过大，导致电子设备消耗的流量可能超过流量套餐中的流量上限等等。因此，可以获取电子设备的设备参数，并根据设备参数对第一显示顺序进行更新，进而使得用户可以基于更新后的第一显示顺序所展示的近期任务的任务卡片，更快地找到其想要结束后台运行的后台运行程序。其中，设备参数指的是与电子设备的设备状态相关的状态参数，可选地，设备参数可以至少包括电子设备的剩余电量值、处理器占用率以及流量消耗值中的一种或多种。
步骤S360：根据所述设备参数，对所述第一显示顺序进行更新。
在一些实施方式中，所述设备参数为所述电子设备的剩余电量值，若所述剩余电量值小于预设电量阈值，基于应用程序的耗电量从大至小的顺序，对去除所述指定应用程序后的所述多个后台应用程序进行排序，得到更新后所述第一显示顺序。可以理解地，当用户于近期任务中结束掉指定应用程序的同时，若获取到剩余电量值小于预设电量阈值，表征当前电子设备的当前电量过低，用户结束掉指定应用程序的目的极有可能是为了节省电子设备的耗电量，后续用户可能还会结束其他后台应用程序的后台运行，以减少电子设备的耗电速度。基于此，电子设备可以根据应用程序的耗电量从大至小的顺序，对去除指定应用程序后的多个后台应用程序进行排序，得到更新后第一显示顺序；并按照更新后的第一显示顺序，将去除所述指定应用程序后的所述多个后台应用程序中的前N个后台应用程序对应的任务标识，叠加显示在所述应用界面的部分区域。如此，使得耗电量更大的后台应用程序显示顺序更靠前，进而使得用户打开近期任务所清除掉的后台应用程序为耗电量更多的应用程序，实现在尽可能少地结束后台应用程序的同时，也能大幅度降低电子设备的耗电速度。
在另一些实施方式中，所述设备参数为所述电子设备的处理器占用率，若所述处理器占用率大于预设占用率，基于应用程序的处理器占用率从大至小的顺序，对去除所述指定应用程序后的所述多个后台应用程序进行排序，得到更新后的所述第一显示顺序。可以理解地，当用户于近期任务中结束掉指定应用程序的同时，若获取到处理器占用率大于预设占用率，表征当前电子设备的当前处理器压力较大，用户结束掉指定应用程序极有可能是因为电子设备的处理器占用率过大，导致前台应用程序出现卡顿等问题，为了提高前台应用程序的运行速度，后续用户可能还会结束其他后台应用程序的后台运行，以提高电子设备的处理速度。基于此，电子设备可以根据应用程序的处理器占用率从大至小的顺序，对去除指定应用程序后的多个后台应用程序进行排序，得到更新后的第一显示顺序；并按照更新后的第一显示顺序，将去除所述指定应用程序后的所述多个后台应用程序中的前N个后台应用程序对应的任务标识，叠加显示在所述应用界面的部分区域。如此，使得处理器占用率更大的后台应用程序显示顺序更靠前，进而使得用户打开近期任务所清除掉的后台应用程序为处理器占用率更多的应用程序，实现在尽可能少地结束后台应用程序的同时，也能大幅度提高电子设备的处理速度。
在本实施例中，在响应于针对指定应用程序的第二触发操作，停止运行所述指定应用程序之后，还可以同时获取电子设备的设备参数，并根据设备参数调整近期任务中的多个后台应用程序的任务标识的显示顺序，使得调整显示顺序后的近期任务列表，更便于用户进行操作，提高用户体验。
请参照图12，图12为本申请再又一实施例提供的一种界面显示方法的流示意图。下面将结合图12对本申请实施例提供的界面显示方法进行详细阐述。该界面显示方法可以包括以下步骤：
步骤S410：显示当前处于前台运行状态的前台应用程序的应用界面。
在本实施例中，步骤S410的具体实施方式可以参阅前述实施方式中的内容，在此不再赘述。
步骤S420：响应于所述第一触发操作，在缩小尺寸后的所述应用界面中的部分区域，按照第二显示顺序叠加显示所述第二显示顺序中的前M个后台应用程序对应的任务标识，所述M为正整数，所述第二显示顺序是基于每个后台应用程序进入后台运行时的时间确定得到。
在本实施例中，电子设备响应于第一触发操作，以桌面图片作为近期任务的显示背景，将缩小尺寸后的应用界面叠加显示在桌面图片的指定区域，同时，在缩小尺寸后的应用界面中的部分区域，根据第二显示顺序，位于前M个后台应用程序中的第一位的后台应用程序对应的任务标识叠加显示在缩小尺寸后的应用界面中的部分区域，并按照预设方向依次显示第二显示顺序中的前M个后台应用程序中其他后台应用程序对应的任务标识。其中，尺寸缩小可以按照预设缩小参数进行缩小，预设方向可以是从右至左、从左至右、从上至下或者从下至上，本实施例对此不作限制。具体如何叠加显示任务标识可以参阅前述实施例中的内容，在此不再赘述。
示例性地，请参阅图13，以设置应用程序为前台应用程序为例，前M个后台应用程序包括线上商城应用程序以及即时通信应用程序，位于前M个后台应用程序中的第一位的线上商城应用程序的任务标识132叠加显示在缩小尺寸后的设置应用程序的应用界面133中的部分区域，按照从右至左的方向在背景界面131中依次显示第二显示顺序中的前M个后台应用程序中其他后台应用程序对应的任务标识，即在线上商城应用程序的左侧显示即时通信应用功能程序的任务标识134。其中，背景界面131可以是以桌面图片作为背景，也可以是以其他预先设置的图片作为背景，本实施例对此不作限制。
步骤S430：响应于第三触发操作，按照所述第二显示顺序，对所述应用界面的部分区域中当前叠加 显示的任务标识进行更新，所述第三触发操作用于切换当前显示的任务标识。
在该方式下，用户可以通过输入用于切换当前显示的任务标识第三触发操作，查看近期任务中的其他后台应用程序对应的任务标识，对应地，电子设备响应于第三触发操作，并按照第二显示顺序，对应用界面的部分区域中当前叠加显示的任务标识进行更新。其中，第三触发操作可以是滑动操作，例如，请参阅图14，图14中包括近期任务的背景界面141、前台应用程序的应用界面143、线上商城应用程序的任务标识142和即时通信应用程序的任务标识144。用户可以在电子设备的屏幕上向右滑动，对应地，电子设备则响应于右滑操作，并按照第二显示顺序，对应用界面143的部分区域中当前叠加显示的任务标识142进行更新。例如，请参阅图15，图15示出了用户在图14的屏幕中通过右滑操作，更新任务标识后的近期任务的显示界面，使得线上商城应用程序的任务标识142被覆盖，即时通信应用程序的任务标识144叠加显示在设置应用程序的应用界面143，其中，任务标识145为第二显示顺序中位于即时通信应用程序后面的后台应用程序的任务标识。
在一些实施方式中，电子设备可以响应于第一触发操作，以桌面图片为近期任务的显示背景，将缩小尺寸后的所述应用界面显示在电子设备的屏幕的第一区域，在除第一区域之外的第二区域中，按照第二显示顺序显示所述第二显示顺序中的前M个后台应用程序对应的任务标识；进一步地，用户可以在第二区域输入第三触发操作，以指示电子设备对第二区域中显示的任务标识进行更新。也就是说，前台应用程序的应用界面始终独立于近期任务中的后台应用程序的任务标识进行显示，即前台应用程序的应用界面中在展示近期任务中，始终全部可见，也能避免在近期任务中前台应用程序的应用界面因被完全覆盖而进入停止状态，导致从近期任务返回至前台应用程序时发生应用重启等问题的发生。同时，在该方式中，近期任务相当于分屏显示，即用户可以在看到前台应用程序的内容的同时，也能翻阅近期任务中的后台应用程序。
例如，请参阅图16，以前台应用程序为设置应用程序为例，电子设备响应于第一触发操作，前M个后台应用程序为即时通信应用程序和相册应用程序为例，将缩小尺寸后的设置应用程序的应用界面163显示在第一区域161，以及按照第二显示顺序显示即时通信应用程序对应的任务标识165和相册应用程序对应的任务标识164在第二区域162；基于此，第三操作可以是在第二区域中的滑动操作，滑动方向可以是从右至左，也可以从左至右，具体的滑动方向是由按照第二显示顺序对任务标识进行显示的显示方向所确定的。
又例如，请参与图17，以前台应用程序为设置应用程序为例，电子设备响应于第一触发操作，前M个后台应用程序为即时通信应用程序和相册应用程序为例，将缩小尺寸后的设置应用程序的应用界面173显示在第一区域171，以及按照第二显示顺序显示即时通信应用程序对应的任务标识175和相册应用程序对应的任务标识174在第二区域172；基于此，第三操作可以是在第二区域中的滑动操作，滑动方向可以是从上至下，也可以从下至上，具体的滑动方向是由按照第二显示顺序对任务标识进行显示的显示方向所确定的。
在本实施例中，电子设备由前台应用程序进入近期任务中，前台应用程序的应用界面始终是显示在桌面背景的指定区域上，即显示区域固定不变，且用于切换当前显示的任务标识的第三触发操作仅能滑动后台应用程序对应的任务标识，无法滑动前台应用程序的应用界面。也就是说，前台应用程序的应用界面在近期任务中始终保持部分区域可见，未被完全覆盖，因此，避免了在近期任务中前台应用程序的应用界面因被完全覆盖而进入停止状态，导致从近期任务返回至前台应用程序时发生应用重启等问题的发生，使得用户从近期任务返回至前台应用程序的操作变得无感，提高了用户体验。
请参照图18，图18为本申请又另一实施例提供的一种界面显示方法的流程示意图。下面将结合图18对本申请实施例提供的界面显示方法进行详细阐述。该界面显示方法可以包括以下步骤：
步骤S510：显示当前处于前台运行状态的前台应用程序的应用界面。
步骤S520：响应于第一触发操作，在所述应用界面的部分区域中叠加显示目标应用程序对应的任务标识。
在本实施例中，步骤S510至步骤S520的具体实施方式可以参阅前述实施方式中的内容，在此不再赘述。
步骤S530：响应于第四触发操作，在所述应用界面的部分区域中叠加显示未处于运行状态的预设应用程序的任务标识，所述第四触发操作用于切换当前显示的任务标识。
在本实施例中，上述未处于运行状态的预设应用程序指既未处于前台运行状态也未处于后台运行状态的预设应用程序，在实际应用中，未处于运行状态的预设应用程序可以是从未启动过的应用程序，也可以是被用户手动结束或电子设备自动结束的处于运行状态(后台运行状态或前台运行状态)的应用程序。请参阅图19，除了在应用界面193的部分区域中叠加显示目标应用程序对应的任务标识194之外，还可以显示第一页码标识191和第二页码标识192。可以理解地，用户切换至近期任务一般是想要进行应用切换，但是，在实际应用中，处于后台运行状态的后台应用程序可能会因为运行前台应用程序的内存不足，而被停止运行，因此，近期任务中可能没有完全包含用户近期启动过的应用程序，导致用户在近期任务中可能无法找到其需要切换的后台应应用程序。因此，电子设备在第一页码标识191对应的显示页面中，叠加显示目标应用程序对应的任务标识，即在第一页码标识191对应的显示页面中显示近期任务。
进一步地，若用户无法从第一页码标识191对应的显示页面中查找到待切换的后台应用程序，则可以通过输入第四触发操作，对应地，电子设备响应于第四触发操作，在应用界面的部分区域中叠加显示未处于运行状态的预设应用程序的任务标识。其中，第四触发操作可以是点击第二页码标识192，也可以是在通过滑动操作，将当前显示页面切换至显示第二页码标识192对应的显示界面。请参阅图20，图20中示出了在设置应用程序对应的应用界面193上，叠加显示切换至第二页码标识192对应的显示界面195，在该显示界面195中，叠加显示未处于运行状态的预设应用程序的任务标识。如此，用户可以在无需退出近期任务的前提也，也查找到待切换被停止后台运行的应用程序。
步骤S540：响应于针对所述预设应用程序的任务标识的第五触发操作，运行所述预设应用程序。
步骤S550：于所述电子设备的第一显示区域显示尺寸缩小后的所述应用界面，于所述电子设备的第二显示区域显示所述预设应用程序的运行界面，所述第二显示区域为除所述第一显示区域之外的其他显示区域。
在实际应用中，用户进入到近期任务中，可能是想同步打开其他后台应用程序。例如，当前应用程序为视频应用程序，若视频应用程序正在播放广告，但是用户并不想观看，同时，用户想在播放广告的时间段的同时，浏览线上商城。此时，若直接切换至线上商城应用程序，则会导致视频应用程序的运行 被中断，用户由线上商城应用程序返回至视频应用程序时，视频应用程序仍会继续播放广告或者重头播放广告。如此，则会大大降低用户的使用体验。
基于此，在本实施例中，用户可以通过输入第五触发操作，选择预设应用程序的任务标识，对应地，电子设备响应于第五触发操作，运行第五触发操作所选择的任务标识对应的预设应用程序。并且，于电子设备的第一显示区域显示尺寸缩小后的应用界面，于电子设备的第二显示区域显示预设应用程序的运行界面。可以理解为，用户在近期任务中，通过输入第五触发操作，实现分屏操作，使得在电子设备在不影响前台应用程序的前台运行的基础上，同时显示另一个应用程序的应用界面供用户交互操作，提高了用户操作的多样性和便捷性。其中，第五触发操作可以是拖动任一任务标识至分屏区域的操作，也可以是双击或者多次点击任一任务标识的操作，具体如何设置第五触发操作可以参阅前述实施例中的内容，在此不再赘述。
示例性地，请参阅图21，第五触发操作选择了图20中的相册应用程序对应的任务标识，对应地，电子设备则运行相册应用程序，于电子设备的第一显示区域212显示尺寸缩小后的设置应用程序的应用界面213，于电子设备的第二显示区域211显示相册应用程序的运行界面214。如此，若相册里存储有包含局域网的登录密码的照片，用户在设置应用程序中输入局域网密码时，可以通过将相册应用程序进行分屏，更方便查看相册中包含有局域网的登录密码的照片，进而更为快速且便捷的在设置应用程序的应用界面中完成对局域网的登录。
在本实施例中，将后台应用程序和未处于后台运行状态的预设应用程序进行分页显示，更便于用户在近期任务中切换到所需要的应用程序。以及，用户可以通过第五触发操作，直接从近期任务触发分屏显示，使得电子设备在不影响前台应用程序的前台运行的基础上，同时显示另一个应用程序的应用界面供用户交互操作，提高了用户操作的多样性和便捷性。
