相关技术中，在多个运行中的应用同时在屏幕上显示的场景下，对于同一时间只能供一个应用进程使用的资源(如临界资源中的音频资源使用权限、打印机等)该如何分配，具体来说，对于临界资源，如音频资源，默认将使用权限分配给最后一个打开的应用，前一个应用释放使用权限，如打印机，排队使用资源，即前一个应用使用完，接着下一个应用使用。上述方法比较混乱，有时会中断用户的使用，给用户带来不好的体验，用户体验不高。对于后台主动显示的应用，如来电的场景(包括语音来电和视频来电)，相关技术中自动退出分屏场景，若用户通话结束后还想使用分屏，则还得重新依次打开分屏的多个应用，用户体验不高。为解决上述问题，本申请提供一种屏幕显示方法及电子设备，通过在多个窗口上同时显示多个运行中的应用时，显示用于区分主窗口和副窗口的提示符，该提示符可用于用户设置主窗口和副窗口，从而可将同一时间只能供一个应用进程使用的资源固定分配给多窗口显示中的一个窗口显示的应用，避免多个屏幕窗口的应用争抢资源，提高用户体验。对于后台主动显示的应用，可将其显示在主窗口或副窗口，不会退出多窗口(例如分屏)，便于用户继续使用多窗口，提高用户体验。下面结合附图详细说明本申请提供的屏幕显示方法及电子设备。
首先，本申请实施例中的术语临界资源，多道程序系统中存在许多进程，它们共享各种资源，然而有很多资源一次只能供一个进程使用。一次仅允许一个应用进程使用的资源称为临界资源。如音频资源。许多物理设备都属于临界资源，如输入机、打印机、磁带机等。
图3为本申请提供的一种屏幕显示方法实施例的流程图，如图3所示，本实施例的方法 应用于具有触摸屏的电子设备中，在电子设备接收多窗口指令之后，可以是在屏幕上显示两个窗口，还可以显示两个以上的窗口，本实施例以显示两个窗口为例，本实施例的方法可以包括：
S101、接收多窗口指令。
具体来说，本申请实施例中的多窗口指令，是指电子设备接收多窗口指令之后，屏幕上可以显示两个或者两个以上的窗口。多窗口不一定是完整的划分整个屏幕，多窗口指令还可以是分屏指令，分屏是对整个屏幕划分。
例如，可以是用户在一个应用的显示界面中输入的多窗口指令(例如两个手指头从屏幕底端向上方滑动)，电子设备响应于该多窗口指令，显示两个窗口；还可以是用户在电子设备的主界面输入的多窗口指令，电子设备响应于该多窗口指令，显示两个窗口。
S102、响应于多窗口指令，显示第一窗口和第二窗口，并在第一窗口上显示第一提示符和第一提示符的状态指示，在第二窗口上显示第二提示符和第二提示符的状态指示，第一窗口显示第一应用的界面，第二窗口显示第二应用的界面，第一提示符和第二提示符的状态为激活状态或未激活状态，处于激活状态的提示符所在的窗口为主窗口，处于未激活状态的提示符所在的窗口为副窗口，第一提示符的状态指示和第二提示符的状态指示根据预设规则确定。
具体地，电子设备响应于多窗口指令，显示两个窗口，图4为本申请提供的一种屏幕显示示意图，如图4所示，电子设备左边显示第一窗口32，右边显示第二窗口33，还可以是上下分屏显示，并在第一窗32上显示第一提示符30和第一提示符的状态指示，在第二窗口33上显示第二提示符31和第二提示符的状态指示，第一提示符30和第二提示符31为相同的图标，第一提示符30和第二提示符31的状态指示可以通过图标显示不同的颜色来指示，例如，激活状态对应的状态指示为红色，未激活状态对应的状态指示为黑色，或者还可以是如图4中所示的图标的线条粗细明显不同。其中，第一窗口显示第一应用的界面，第二窗口显示第二应用的界面，比如第一窗口显示微信的界面，第二窗口显示一购物应用的界面。通过提示符的状态指示，用户可以知晓哪个界面是主窗口，哪个界面是副窗口。需要说明的是，第一提示符或第二提示符在对应窗口的位置不限。
其中，第一提示符的状态指示和第二提示符的状态指示根据预设规则确定，例如，以分屏为例，预设规则可以为：在左右分屏时，初始设置左边窗口为主窗口，右边窗口为副窗口，在上下分屏时，初始设置上边窗口为主窗口，下边窗口为副窗口。
在一种可实施的方式中，预设规则还可以为：确定第一应用和第二应用打开的先后顺序，将先打开的应用对应的窗口确定为主窗口，将后打开的应用对应的窗口确定为副窗口；或者，
将后打开的应用对应的窗口确定为主窗口，将先打开的应用对应的窗口确定为副窗口。
具体来说，以多窗口显示中的分屏场景为例，例如可以是在首次进行分屏场景时，将先打开的应用对应的窗口确定为主窗口，将后打开的应用对应的窗口确定为副窗口。在不是首次进行分屏时，将最近一次打开的应用确定为主窗口，其它的窗口为副窗口。
在一种可实施的方式中，用户可以通过操作提示符(例如点击提示符)来变更窗口的提示符的状态，通过用户操作提示符，可以变更窗口的主副之分。此时，本实施例的方法还可以包括：
S104、接收对第一提示符或第二提示符的操作。
S105、响应于对第一提示符或第二提示符的操作，变更第一提示符或第二提示符的状态。
进一步地，在预设时间内未接收到对第一提示符的操作时，不显示第一提示符；在预设时间内未接收到对第二提示符的操作时，不显示第二提示符。预设时间例如为5s，预设时间后提示符自动消失，避免影响用户正常使用。
进一步地，提示符消失之后，当用户需要重新调整主副窗口时，提示符会自动弹出，此时，本实施例的方法还可以包括：
S106、接收到对触摸屏的操作。
S107、响应于对触摸屏的操作，在所述第一界面上重新显示所述第一提示符，在所述第二界面上重新显示所述第二提示符。
例如，用户在调整第一窗口或第二窗口的大小，即屏幕的分割线的时候，两个界面上的提示符会同时自动弹出。
需要说明的是，第一界面上的第一提示符和第二界面上的第二提示符是同时消失或者同时显示的。
S103、存储主窗口显示的应用，主窗口显示的应用为第一应用或第二应用。
具体地，在用户确定了主副窗口之后，可以是电子设备中的窗口管理器存储主窗口显示的应用，从而，电子设备知道了主窗口显示的应用和副窗口显示的应用，可以将同一时间只能供一个应用进程使用的资源固定分配给多窗口显示中的一个窗口显示的应用，该窗口可以是主窗口，也可以是副窗口，避免多个屏幕窗口的应用争抢资源，提高用户体验。而且，对于后台主动显示的应用(例如通话应用中的语音来电或者通讯应用中的视频来电或语音来电)，可将其显示在主窗口或副窗口，不会退出多窗口(例如分屏)，便于用户继续使用多窗口，提高用户体验。此时，本实施例的方法还可以包括如下三种可实施的方式：
方式一、接收第三应用的临界资源使用权限获取申请，第三应用为第一应用或第二应用，若第三应用是已存储的主窗口显示的应用，则将临界资源使用权限分配给第三应用。
具体来说，即就是将临界资源使用权限分配给主窗口显示的应用，这样可以避免多个屏幕窗口的应用争抢资源，例如，临界资源为音频资源，在主副窗口中，主窗口一旦获取音频资源，则副窗口无法获取音频资源。也就是说，用户一旦在主窗口中使用音乐APP播放音乐，在副窗口中无论是看视频，打游戏，都不会占用音频资源，避免多个窗口的应用来回争抢。用户可以无忧的在主窗口听音乐，副窗口根据字幕看视频。
方式二、接收用户输入给电子设备的指令，根据用户输入给电子设备的指令对主窗口进行相应的处理。
其中，用户输入给电子设备的指令包括用户操作电子设备的指令和语音输入指令。
具体来说，在分屏显示后，用户操作电子设备，以手机为例，如操作手机的导航键、外接键盘、蓝牙键盘等，还有调整音量的按键，还有语音输入等，这些均是用户输入给电子设备的指令，接收到用户输入给电子设备的指令后，将该指令分发到主窗口，根据指令对主窗口进行相应的处理。对于副窗口来说，只能接收触屏的指令，根据触屏指令执行相应的处理。
通过本方式的方法，在分屏场景下，可以避免用户操作电子设备的指令会在不同分屏 窗口来回切换。
方式三、接收后台发送的第四应用显示指令，在主窗口显示第四应用。
在方式三中，进一步地，还可以包括：接收第四应用结束指令，在主窗口重新显示主窗口显示的应用。
具体地，上述第四应用是后台主动显示的应用，是与第一应用和第二应用不同的应用，对于后台主动显示的应用，例如通话应用中的语音来电或者通讯应用中的视频来电或语音来电，会主动显示在电子设备的屏幕上，在本申请中，当接收到后台发送的第四应用显示指令时，可将第四应用显示在主窗口，还可以显示在副窗口，不会退出分屏，当第四应用结束显示时，在主窗口重新显示之前主窗口显示的应用，便于用户继续使用分屏，提高用户体验。
本实施例提供的屏幕显示方法，通过接收到多窗口指令之后，响应于多窗口指令，显示第一窗口和第二窗口，并在第一窗口上显示第一提示符和第一提示符的状态指示，在第二窗口上显示第二提示符和第二提示符的状态指示，第一窗口显示第一应用的界面，第二窗口显示第二应用的界面，第一提示符和第二提示符的状态为激活状态或未激活状态，处于激活状态的提示符所在的窗口为主窗口，处于未激活状态的提示符所在的窗口为副窗口，最后存储主窗口显示的应用，主窗口显示的应用为第一应用或第二应用。从而，电子设备知道了主窗口显示的应用和副窗口显示的应用，可以将同一时间只能供一个应用进程使用的资源固定分配给多窗口显示中的一个窗口显示的应用，避免多个屏幕窗口的应用争抢资源，提高用户体验。而且，对于后台主动显示的应用，可将其显示在主窗口或副窗口，不会退出多窗口(例如分屏)，便于用户继续使用多窗口，提高用户体验。
下面采用三个具体的实施例，对图3所示方法实施例中的三种方式的技术方案进行详细说明。
实施例一
临界资源，即同一时间只能供一个应用进程使用的资源，如音频资源、打印机等，本实施例中以音频资源为例来说明分屏场景下临界资源的分配。电子设备系统中不能同时有两个或两个以上的应用同时使用音频资源，比如两个音乐APP同时播放音乐，系统则没法听了。在现有的安卓系统中，两个应用同时打开两个音乐应用，则先打开的那个音乐应用会停止播放，后面打开的才会继续播放。也就是说Android默认最后一个应用获取音频资源的使用权限，其他的应用必须释放音频资源的使用权限。该方法比较混乱，有时会中断用户的使用，给用户带来不好的体验，用户体验不高。在本申请实施例中，通过在多窗口显示时，区分主窗口和副窗口，窗口管理器(即窗口管理服务)存储主窗口显示的应用，并且提供对外查询接口，音频资源管理器(AudioManager)在接收到应用申请音频资源使用权限时，会通过窗口管理器查询该应用是否是主窗口显示的应用，若是则将音频资源使用权限分配给该应用，若不是，则不分配，或者，还可以是分配虚假的音频资源使用权限给该应用，该应用获取到虚假的音频资源使用权限时，根据虚拟的音频输出句柄。通过将临界资源使用权限分配给主窗口显示的应用，这样可以避免多个屏幕窗口的应用争抢资源，例如，用户一旦在主窗口中使用音乐APP播放音乐，在副窗口中无论是看视频，打游戏，都不会占用音频资源，避免多个窗口的应用来回争抢。用户可以无忧的在主窗口听音乐，副窗口根据字幕看视频。
实施例二
在分屏显示后，用户操作电子设备，如操作电子设备的导航键、外接键盘、蓝牙键盘等，还有调整音量的按键，还有语音输入等，这些均是用户输入给电子设备的指令，这也意味着用户输入给电子设备的指令也是一种临界资源，在本申请实施例中，通过在多窗口显示时，区分主窗口和副窗口，可以设置用户输入给电子设备的指令全部分发至主窗口，副窗口只接收触屏指令。
具体地，在安卓系统中，输入电子设备指令的传递流程，可以大致分为三个部分：输入系统部分、窗口管理器处理部分和视图(View)处理部分，窗口管理器作为窗口的管理者，或配合输入管理服务(Input Manager Service)将输入指令交由合适的应用或窗口来处理。本实施例中，由于在多窗口显示时，区分主窗口和副窗口，可以设置用户输入给电子设备的指令全部分发至主窗口，主窗口根据指令对主窗口进行相应的处理。副窗口只接收触屏指令，副窗口根据触屏指令执行相应的处理。从而，在分屏场景下，可以避免用户操作电子设备的指令会在不同分屏窗口来回切换。
实施例三
本实施例中，由于在多窗口显示时，区分主窗口和副窗口，当接收到后台发送的第四应用显示指令时，可将第四应用显示在主窗口，还可以显示在副窗口，不会退出分屏，当第四应用结束显示时，在主窗口重新显示之前主窗口显示的应用，便于用户继续使用分屏，提高用户体验。例如，在显示通话界面之前，安卓窗口管理服务会去窗口管理器查询当前哪个窗口是主窗口，根据查询结果决定通话界面的显示位置。
需要说明的是，上述实施例中是以多窗口显示场景下显示两个窗口为例，也可以是两个以上窗口，当是两个以上窗口时，类似地，在每个窗口上显示应用时同时显示提示符，只有一个提示符是激活状态，即就是只有一个窗口是主窗口，其它窗口都是副窗口，在临界资源的分配场景下，可以将临界资源的使用权限分配给主窗口，用户输入给电子设备的指令也可全部分发至主窗口，后台发送的应用也可以显示在主窗口，不会退出多窗口显示，详细的过程与两个窗口的方案类似，下面结合图5进行说明。
图5为本申请提供的一种屏幕显示方法实施例的流程图，如图5所示，本实施例的方法应用于具有触摸屏的电子设备中，在电子设备接收多窗口指令之后，可以是在屏幕上显示两个窗口，还可以显示两个以上的窗口，本实施例以显示三个窗口为例，本实施例的方法可以包括：
S201、接收多窗口指令。
S202、响应于多窗口指令，显示第一窗口、第二窗口和第三窗口，并在第一窗口上显示第一提示符和第一提示符的状态指示，在第二窗口上显示第二提示符和第二提示符的状态指示，在第三窗口上显示第三提示符和第三提示符的状态指示，第一窗口显示第一应用的界面，第二窗口显示第二应用的界面，第三窗口显示第三应用的界面，第一提示符、第二提示符和第三提示符的状态为激活状态或未激活状态，处于激活状态的提示符所在的窗口为主窗口，处于未激活状态的提示符所在的窗口为副窗口，第一提示符的状态指示、第二提示符和第三提示符的状态指示根据预设规则确定。
在一种可实施的方式中，预设规则可以为：确定第一应用、第二应用和第三应用打开的先后顺序，将先打开的应用对应的窗口确定为主窗口，将其余的应用对应的窗口确定为 副窗口；或者，将后打开的应用对应的窗口确定为主窗口，将其余应用对应的窗口确定为副窗口。
在一种可实施的方式中，预设规则可以为：在左右显示时，初始设置位于屏幕最左方或最右方的窗口为主窗口，其余窗口为为副窗口，或者，还可以其它方式。
在一种可实施的方式中，用户可以通过操作提示符(例如点击提示符)来变更窗口的提示符的状态，通过用户操作提示符，可以变更窗口的主副之分。此时，本实施例的方法还可以包括：
S204、接收对第一提示符或第二提示符或第三提示符的操作。
S205、响应于对第一提示符或第二提示符或第三提示符的操作，变更第一提示符或第二提示符或第三提示符的状态。
进一步地，在预设时间内未接收到对第一提示符的操作时，不显示第一提示符；在预设时间内未接收到对第二提示符的操作时，不显示第二提示符；在预设时间内未接收到对第三提示符的操作时，不显示第三提示符。预设时间例如为5s，预设时间后提示符自动消失，避免影响用户正常使用。
进一步地，提示符消失之后，当用户需要重新调整主副窗口时，提示符会自动弹出，此时，本实施例的方法还可以包括：
S206、接收到对触摸屏的操作。
S207、响应于对触摸屏的操作，在所述第一界面上重新显示所述第一提示符，在所述第二界面上重新显示所述第二提示符，在所述第三界面上重新显示所述第三提示符。
例如，用户在调整屏幕的分割线的时候，三个界面上的提示符会同时自动弹出。
需要说明的是，第一界面上的第一提示符、第二界面上的第二提示符和第三界面上的第三提示符是同时消失或者同时显示的。
S203、存储主窗口显示的应用，主窗口显示的应用为第一应用、第二应用和第三应用中的任一个。
具体地，在用户确定了主副窗口之后，可以是电子设备中的窗口管理器存储主窗口显示的应用，从而，电子设备知道了主窗口显示的应用和副窗口显示的应用，可以将同一时间只能供一个应用进程使用的资源固定分配给多窗口显示中的一个窗口显示的应用，该窗口可以是主窗口，也可以是副窗口，避免多个屏幕窗口的应用争抢资源，提高用户体验。而且，对于后台主动显示的应用(例如通话应用中的语音来电或者通讯应用中的视频来电或语音来电)，可将其显示在主窗口或副窗口，不会退出多窗口(例如分屏)，便于用户继续使用多窗口，提高用户体验。具体的过程可以参见图3所示实施例中的方式一、方式二和方式三的描述，此处不再赘述。
