具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
可以理解，本申请所使用的术语“第一”、“第二”等可在本文中用于描述各种元件，但这些元件不受这些术语限制。这些术语仅用于将第一个元件与另一个元件区分。举例来说，在不脱离本申请的范围的情况下，可以将第一时长阈值称为第二时长阈值，且类似地，可将第二时长阈值称为第一时长阈值。第一时长阈值和第二时长阈值两者都是时长阈值，但其不是同一时长阈值。
图1为一个实施例中显示屏检测方法的流程图。如图1所示，该显示屏检测方法包括步骤102至步骤108。其中：
步骤102，检测是否存在图层在电子设备的显示屏中显示。
在一个实施例中，电子设备中可以安装一个或多个应用程序，用户可以通过应用程序实现应用操作。例如，通过应用程序看视频、听音乐、购物、玩游戏等。应用程序在前台运行时，在电子设备的显示屏上形成交互界面，用户可以通过交互界面来对应用程序进行操作。
具体的，显示屏上形成的交互界面由一个或多个应用程序对应的图层叠加形成的，不同的图层叠加形成的交互界面可能不同。例如，电子设备的应用程序A对应的图层为图层A，当应用程序A切换到前台时，显示屏中显示的图层就可能包括图层A、桌面图层和壁 纸图层；当前台没有运行应用程序的时候，显示屏中显示的图层就只包括桌面图层和壁纸图层。
图层显示的顺序、透明度、形状、大小等可以调节，显示的图层的顺序、透明度、形状和大小不同时，形成的交互界面也不同。例如，显示屏中显示的图层包括图层A、图层B和图层C，若显示屏是按照图层A→图层B→图层C的顺序由下至上显示的，那么用户看到的就是图层C中的内容。若按照图层A→图层B→图层C的顺序右下至上显示，且图层的透明度分别为0％、0％和100％，那么用户看到的就是图层B中的内容。
步骤104，当检测到不存在图层在电子设备的显示屏中显示时，重启电子设备的系统。
电子设备可以检测是否存在图层在显示屏中显示。如果不存在图层在显示屏中显示，则可以判定是由于电子设备的系统故障导致无图层显示，可以将电子设备的系统进行重启。具体的，检测是否存在图层在显示屏中显示，是指检测显示屏是否输出了显示信号。若显示屏中没有显示信号输出，则说明显示屏中没有显示图层。
可以理解的是，电子设备在待机状态的时候，显示屏中是没有输出显示信号的，即电子设备在待机状态下，显示屏中不显示图层。因此为了避免误判，可以在检测电子设备处于运行状态下时，执行步骤102。也就是说，当电子设备在处于运行状态时，若检测到显示屏中没有输出信号，则判定电子设备的系统故障。
步骤106，当检测到存在图层在电子设备的显示屏中显示时，检测图层是否按照设定规则在显示屏中显示。
当检测到显示屏中有显示信号输出时，则认为存在图层在显示屏中显示。当检测到存在图层在电子设备的显示屏中显示时，则进一步检测显示屏中显示的图层是否是按照设定规则进行显示的。正常情况下，图层应该是按照设定规则去显示的，若图层未按照设定规则进行显示，则可以认为是显示的图层对应的目标应用程序出现故障。
其中，设定规则是指设定的显示屏中显示图层的显示规则。例如，显示屏中显示了三个图层，即图层1、图层2和图层3。假设设定的规则是按照图层1→图层2→图层3的顺序显示的，而实际检测到的是按照图层3→图层1→图层2的顺序显示的，那么就可以认为显示屏中显示的图层1、图层2、图层3未按照设定规则显示。又例如，显示屏中显示的图层A设定的透明度为80％，而实际显示的图层A的透明度为100％，那么就可以认为图 层A未按照设定规则显示。
在一个实施例中，在判断显示屏中的图层是否按照设定规则显示时，可以对显示屏中显示的全部图层进行判断，也可以对显示屏中显示的全部图层中的一个或多个图层进行判断是否符合设定规则。具体的，可以从显示屏中显示的图层中确定目标图层，判断目标图层是否按照设定规则在显示屏中显示。当目标图层未按照设定规则在显示屏中显示时，重启目标图层对应的目标应用程序。例如，显示屏中显示的图层包括图层A、图层B、图层C、图层D，则可以将图层D作为图层，只要图层D显示在最上层，则认为图层是按照设定规则显示的，其他位于图层D下方显示的图层A、图层B、图层C可以不考虑。
步骤108，当图层未按照设定规则在显示屏中显示时，重启显示屏中所显示的图层对应的目标应用程序。
当上述图层未按照设定规则在显示屏中显示时，则认为是应用程序故障，电子设备可以控制显示屏中显示的图层对应的目标应用程序重启。例如，目标应用程序可能是电子设备前台运行的应用程序，当检测到图层未按照设定规则在显示屏显示时，则将前台运行的目标应用程序重启。
上述实施例提供的显示屏检测方法，可以检测是否存在图层在电子设备的显示屏中显示。当检测到不存在图层在电子设备的显示屏中显示时，可判定电子设备的系统故障，则重启电子设备的系统。当检测到存在图层在电子设备的显示屏中显示，但图层未按照设定规则在显示屏中进行显示时，可判定显示屏中所显示的图层对应的目标应用程序故障，则重启目标应用程序。这样可以根据显示屏中显示的图层，检测电子设备的黑屏、花屏等故障，从而通过重启系统或应用程序的方式解决故障，提高了电子设备的使用效率。
图2为另一个实施例中显示屏检测方法的流程图。如图2所示，该显示屏检测方法中包括步骤202至步骤220。其中：
步骤202，检测是否存在图层在电子设备的显示屏中显示。
在一个实施例中，电子设备在检测显示屏中是否显示图层时，可以实时对显示屏进行检测，也可以每间隔一定时间段对显示屏进行一次检测，在此不做限定。例如，电子设备可以每间隔1秒钟检测一次，也可以每间隔5秒钟检测一次。
具体的，当电子设备在待机状态下的时候，显示屏是处于黑屏状态的，因此在待机状态下可以不用对显示屏进行检测。当电子设备处于运行状态时，再执行步骤202，开始对显示屏进行检测。
步骤204，当检测到不存在图层在电子设备的显示屏中显示时，开始计时。
步骤206，当计时时长大于第一时长阈值且不存在图层在显示屏中显示时，重启电子设备的系统。
当检测到不存在图层在电子设备的显示屏中显示时，电子设备会立即启动计时器开始计时。开始计时后，电子设备进入等待状态，在当计时时长大于第一时长阈值且不存在图层在显示屏中显示时，电子设备会停止等待，并对计时器清零，然后将系统重启。当计时时长小于或等于第一时长阈值且检测到目标层在显示屏中显示时，电子设备也会停止等待，然后电子设备会对计时器清零，并进入正常的运行状态。
例如，当电子设备检测到显示屏中没有显示图层时，电子设备会立即启动计时器，并进入等待状态。当计时时长超过5秒钟还未检测到显示屏中显示图层时，电子设备会将计时器清零，将电子设备的系统重启。
在一个实施例中，在执行步骤206之前，电子设备可以根据电量的剩余情况调节第一时长阈值，当电子设备的剩余电量较多的时候，使电子设备等待的时间更长，电子设备的剩余电量较少的情况下，直接重启电子设备，这样可以减少电子设备在等待过程中消耗的电量。具体的，获取电子设备的剩余电量，根据预先建立的剩余电量和第一时长阈值的对应关系获取剩余电量对应的第一时长阈值。
例如，预先建立的剩余电量和第一时长阈值的对应关系如下：电量为0～20％、20％～60％、60％～100％时，对应的第一时长阈值分别为1秒、5秒、8秒。当电子设备在检测到显示屏中无图层显示时，开始计时进入等待，并获取电子设备的剩余电量。若电子设备的剩余电量为58％，则第一时长阈值就对应为5秒，当等待时长达到5秒的时候，就将系统进行重启。
步骤208，当检测到存在图层在电子设备的显示屏中显示时，获取显示屏中显示的图层对应的目标应用标识，根据预先建立的目标应用标识与第二时长阈值的对应关系获取目标应用标识对应的第二时长阈值。
当存在图层在显示屏中显示时，可以获取显示屏中显示的图层对应的目标应用标识。其中，目标应用标识用于标示显示屏中显示的图层所对应的目标应用程序。例如，目标应用标识可以是目标应用程序的应用包名，在此不做限定。电子设备可以预先建立目标应用标识与第二时长阈值的对应关系，在获取到显示屏中显示的图层对应的目标应用标识后，根据建立的对应关系获取所述目标应用标识对应的第二时长阈值。
步骤210，检测显示屏中显示的图层是否超过第二时长阈值未更新。
在获取到第二时长阈值之后，检测显示屏中显示的图层是否超过第二时长阈值未更新，当显示屏中的图层超过第二时长阈值未更新时，则认为显示屏中显示的图层产生的了卡顿。
第二时长阈值是根据目标应用标识获取的，也即不同应用程序显示的图层的判断标准不一样。例如，对于游戏类应用程序，显示屏更新画面的速度往往比较快，那么游戏类应用程序对应的第二时长阈值就可以设置得比较小；对于小说类应用程序，显示屏更新画面的速度往往比较慢，那么小说类应用程序对应的第二时长阈值就可以设置得比较大。
具体的，当显示屏中显示的图层更新时，应用程序会将更新的图层发送给窗口管理服务(WindowManagerService)，然后通过窗口管理服务将图层发送给显示屏进行显示。电子设备可以根据窗口管理服务上一次接收到的图层的时刻，得到显示屏中显示的图层上一次更新的时刻，从而得到显示屏中显示的图层未更新的时长。
步骤212，当检测到显示屏中显示的图层超过第二时长阈值未更新时，判定图层未按照设定规则在显示屏中显示。
当检测到显示屏中显示的图层超过第二时长阈值未更新时，则认为显示屏中显示的图层产生的了卡顿，即判定图层未按照设定规则在显示屏中显示。例如，第二时长阈值为5秒，当显示屏中显示的图层超过5秒没有更新时，就会认为图层未按照设定规则在显示屏中显示。
步骤214，当图层未按照设定规则在显示屏中显示时，统计显示屏中所显示的图层对应的目标应用程序在预设时长内的重启次数。
当图层未按照设定该规则在显示屏中显示时，认为显示屏中所显示的图层对应的目标应用程序产生了异常，则需要将目标应用程序进行重启。在对目标应用程序进行重启之前， 可以统计目标应用程序在预设时长内重启的次数，根据统计的重启次数判断是都将目标应用程序进行重启。
步骤216，当统计的重启次数小于或等于次数阈值时，重启目标应用程序。
当统计的重启次数大于次数阈值时，认为目标应用程序重启太频繁，这样频繁重启可能会造成电子设备的资源浪费，则可以向用户发出提示信息。当统计的重启次数小于或等于次数阈值时，则可以直接将目标应用程序重启。
步骤218，当统计的重启次数大于次数阈值时，输出提示信息。
步骤220，当接收到根据提示信息输入的重启指令时，重启目标应用程序。
当重启次数大于次数阈值时，电子设备可以输出提示信息，用于提示用户目标应用程序重启太频繁。用户在接收到提示信息之后，可以根据提示信息输入指令。当用户输入重启指令时，电子设备就可以重启目标应用程序。例如，电子设备可以统计目标应用程序在10分钟内重启的次数，当重启次数小于或等于5次时，直接将目标应用程序重启；当重启次数大于5次时，输出提示信息，用以提示用户目标应用程序的重启频率过高。
具体的，上述提示信息的形式在此不做限定。例如，上述提示信息可以是以声音、提示框、震动等形成输出的，当用户接收到该提示信息时，就可以根据提示信息输入重启指令。用户还可以根据提示信息输入停止指令，当电子设备检测到停止指令时，目标应用程序停止运行。
上述实施例提供的显示屏检测方法，可以检测是否存在图层在电子设备的显示屏中显示。当检测到不存在图层在电子设备的显示屏中显示时，可判定电子设备的系统故障，则重启电子设备的系统。当检测到存在图层在电子设备的显示屏中显示，但图层未按照设定规则在显示屏中进行显示时，可判定显示屏中所显示的图层对应的目标应用程序故障，则重启目标应用程序。这样可以根据显示屏中显示的图层，检测电子设备的黑屏、花屏等故障，从而通过重启系统或应用程序的方式解决故障，提高了电子设备的使用效率。
在本申请提供的其他是实施例中，检测图层是否按照设定规则显示的步骤还可以包括：
步骤302，检测图层是否按照设定排列顺序在显示屏中显示。
步骤304，当检测到图层未按照设定排列顺序在显示屏中显示时，判定图层未按照设 定规则在显示屏中显示。
当检测到电子设备的显示屏中显示图层时，检测显示屏中显示的图层是否按照设定排列顺序进行显示的。可以理解的是，应用程序在运行过程中，会在显示屏上生成不同的交互界面，因此显示屏中显示的图层也是在实时调整的。例如，前台应用程序退出时，电子设备中可能只显示壁纸图层和桌面图层，且壁纸图层显示在桌面图层的下方。当前台应用程序开始运行时，前台应用程序对应的前台应用图层会显示在壁纸图层和桌面图层的上方，以使得用户可以通过前台应用图层中显示的内容实现交互操作。
也就是说，电子设备在运行过程中，显示屏中所显示的图层的排列规则是不断再变化的。应用程序在运行过程中可以请求电子设备更改排列规则，从而使得电子设备可以根据排列规则来显示图层。例如，当应用程序切换到前台时，应用程序可以请求电子设备的窗口管理服务对图层的顺序进行调整。
图4为一个实施例中显示屏显示图层的示意图。如图4所示，电子设备的显示屏40中显示了图层402、图层404和图层406。在显示图层402、图层404和图层406的时候，设定排列顺序为图层402→图层404→图层406。当显示屏40在显示图层的时候，若检测显示的图层的排列顺序为图层402→图层404→图层406，则认为显示屏40当前是按照设定规则显示图层402、图层404和图层406的。假设检测显示的图层的排列顺序为图层404→图层402→图层406，则认为显示屏40当前未按照设定规则显示图层402、图层404和图层406。
在本申请提供的其他是实施例中，在检测到图层超过第二时长阈值未更新的时候，判断图层是否按照设定规则在显示屏中显示的步骤具体包括：
步骤502，当检测到显示屏中显示的图层超过第二时长阈值未更新时，检测图层缓冲器中是否存在待显示图层，或检测显示屏中显示的图层中所有像素点的像素值是否都为预设像素值；其中，图层缓冲器用于存储显示屏显示的图层。
在一个实施例中，检测到显示屏中显示的图层长时间未更新时，可以进一步检测图层缓冲器中是否存储了待显示的图层，或者检测显示屏中显示的图层中的像素点是否满足预设条件，然后根据检测结果判断图层是否按照设定规则显示。
应用程序在电子设备的前台运行时，会向电子设备请求一个图层缓冲器，应用程序在 需要显示图层时，会将需要显示的图层存放在定义的图层缓冲器中，显示屏就可以对图层缓冲器中的图层进行显示。因此，当电子设备检测到显示屏中的图层超过第二时长阈值未更新时，可以检测图层缓冲器中是否存在待显示图层，若图像缓冲器中不存在待显示图层，则认为该图像缓冲器为无效的图像缓冲器，则认为应用程序出现异常。
电子设备还可以检测是否显示屏中显示的图层中所有像素点的像素值都为预设像素值，当显示屏中显示的图层中所有像素点的像素值都为预设像素值时，认为应用程序出现异常。
步骤504，当图层缓冲器中不存在待显示图层或显示屏中显示的图层中所有像素点的像素值为预设像素值时，判定图层未按照设定规则在显示屏中显示。
当图层缓冲器中不存在待显示图层或显示屏中显示的图层中所有像素点的像素值为预设像素值时，判定图层未按照设定规则在显示屏中显示，即应用程序出现异常。其中，预设像素值为预先设定的像素值。例如，当图层中所有像素点的像素值全为0，或者小于某个较小的像素值时，认为图层未按照设定规则在显示屏中显示。
图6为又一个实施例中显示屏检测方法的流程图。如图6所示，首先对电子设备的显示屏中显示的图层进行检测，并根据检测的结果识别电子设备的显示屏当前所处的场景。当识别到显示屏中无图层显示时，判定由于电子设备的系统异常导致显示屏黑屏，然后对电子设备进行系统重启。当识别到显示屏中有图层显示，但图层的显示顺序错乱的时候，判定由于应用程序异常导致显示屏花屏，此时可以将图层对应的目标应用程序重启。当识别到显示屏中有图层显示，但图层长时间无刷新时，可以进一步判断目标应用程序定义的图层缓冲器是否无效，或判断显示屏中显示的所有图层合成之后的画面中包含的所有像素点的像素值是否都为0。若目标应用程序定义的图层缓冲器无效，或显示屏中显示的所有图层合成之后的画面中包含的所有像素点的像素值都为0，则判定是目标应用程序异常导致的黑屏，然后将目标应用程序重启。
应该理解的是，虽然图1、2、3、5、6的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图1、2、3、5、6中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶 段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
