目前各种常见的电子设备，比如手机、平板电脑等，为了给用户更好的使用体验，屏幕越来越大，给用户提供更丰富的信息，可以提高人机交流的效率。但是，这类电子设备的屏幕太大也会影响其便携性能，而折叠式电子设备由于可以在展开时给用户大屏体验，也可以在折叠时满足便携需求，从而开始推广使用。
折叠式电子设备在折叠时，面向用户的显示屏称为主屏，折叠在电子设备背部的显示屏称为副屏，用户可以看到主屏上显示的内容，而看不到副屏。而折叠式电子设备在折叠后，用户只能用手指直接对主屏进行操作，以实现打开主屏上的应用或控件等，在有些场景下，比如单手握持时，用户希望可以通过对副屏进行操作以实现在主屏显示相应的操作结果，由于用户看不到手机的副屏，所以在用户对副屏进行操作时，用户并不能看到操作位置是否是想要操作的位置，可能会产生误操作，从而影响用户体验。
发明内容
本申请实施例提供一种操作提示的方法和电子设备，以实现在主屏对作用在副屏上的操作进行提示，防止误操作。
第一方面，本申请实施例提供了一种操作提示的方法，应用于具有可折叠触摸屏的电子设备，可折叠触摸屏包括第一屏和第二屏，第一屏与第二屏之间的夹角小于预设夹角，在该方法中，电子设备检测到对第一屏上的显示触摸区域的第一操作；响应于第一操作，根据位置映射关系，在第二屏对应位置显示提示标识，其中，提示标识在第二屏的显示位置与第一操作的触摸位置关联，位置映射关系根据第一屏与第二屏的显示触摸区域确定。
本申请实施例中，电子设备中的第一屏的显示触摸区域与第二屏的显示触摸区域之间存在位置映射关系，这样用户对第一屏的显示触摸区域进行第一操作时，该第一操作在显示触摸区域中的操作位置，可以映射到第二屏上的显示触摸区域中，从而在第二屏中与该第一操作存在位置映射关系的位置显示提示标识，以第一屏为副屏，第二屏为主屏为例，在副屏上进行操作，就可以实现在主屏上对作用在副屏上的操作进行提示，防止误操作。
在一种可能的设计中，第一屏的显示触摸区域的面积小于或等于第二屏的显示触摸区域的面积。这样用户手指只需要在第一屏上小面积的显示触摸区域进行操作，就可以实现对大面积的第二屏的整个显示触摸区域进行操作，便于用户操作。
在一种可能的设计中，第一操作可以为点击操作。用户对第一屏的显示触摸区域进行点击操作，电子设备可以响应于该点击操作在第二屏的显示触摸区域显示提示标识，提示标识可以为箭头，也可以为圆圈，也可以为其它形状，此处不作限制。
在一种可能的设计中，第一操作可以为滑动操作，提示标识可随着手指在显示触摸区域中的滑动而在第二屏中移动。这样用户在第一屏的显示触摸区域进行滑动操作，可以在第二屏上看到提示标识的移动轨迹，从而可以实现在想要进行下一步操作的位置进行相应操作。
在一种可能的设计中，电子设备响应于所述第一操作，根据位置映射关系，在所述第二屏显示提示标识之后，所述方法还包括：对第二屏中的提示标识所在位置的显示内容进行识别；响应于沿第一方向的滑动操作，对识别的显示内容进行放大；响应于沿第二方向的滑动操作，对识别的显示内容进行缩小。应理解，点击操作和滑动操作可以由同一手指完成，比如，用户右手的食指先进行点击操作，实现对提示标识所在位置的显示内容进行识别，再采用食指进行滑动操作。或者，点击操作和滑动操作也可以由不同手指完成，比如，用户右手的食指先进行点击操作，右手的中指进行滑动操作，当然，点击操作和滑动操作也可以是由不同手的两个手指完成。
通过该设计，用户可以对第一屏的显示触摸区域进行点击操作和滑动操作，实现对第二屏显示的想要进一步仔细查看内容进行放大，或者，对第一屏显示的内容进行缩小。
在一种可能的设计中，第一操作为点击操作，点击操作在第一屏的触摸位置对应第二屏上显示的应用的位置；响应于第一操作，根据位置映射关系，在第二屏显示提示标识之后，还可以响应于点击操作，在第二屏打开应用。
应理解，在第一屏的显示触摸区域进行任何操作，都可以在第二屏上的显示触摸区域显示相应的操作执行结果。
在一种可能的设计中，第一屏上的显示触摸区域设有指纹传感器，第一操作为触摸操作；在响应于第一操作，在第二屏显示提示标识之前，还可以通过指纹传感器采集触摸操作对应的指纹，并验证指纹与指纹模板库中的指纹模板匹配。
通过该设计，满足指纹与指纹模板库中的指纹模板匹配的条件的用户才可以对第一屏的显示触摸区域进行操作，从而可以增加安全性，当然，用户可以将常用的手指的指纹录入指纹模板库中，这样也可以防止用户的其它手指误触。
在一种可能的设计中，第一屏上的显示触摸区域设有指纹传感器，第一操作为触摸操作；响应于第一操作，在第二屏显示提示标识，包括：通过指纹传感器采集触摸操作对应的指纹，并在第二屏上显示指纹。如此，用户可以在第一屏的显示触摸区域录入指纹时，看到第二屏上显示指纹录入的情况，以便采集到完整可用的指纹。
在一种可能的设计中，预设夹角小于或等于180度。这样第一屏与所述第二屏之间的夹角小于180度，也就是说，这时电子设备的可折叠触摸屏处于折叠状态，可采用对第一屏进行操作，并在第二屏进行提示的方式来防止误触。
第二方面，本申请实施例提供一种电子设备，包括可折叠触摸屏、处理器和存储器，所述可折叠触摸屏包括第一屏和第二屏，所述第一屏与所述第二屏之间的夹角小于预设夹角，所述存储器用于存储一个或多个计算机程序；当所述存储器存储的一个或多个计算机程序被所述处理器执行时，使得该电子设备能够实现上述第一方面以及第一方面中任一种可能的设计的方法。
第三方面，本申请实施例还提供一种装置，该装置包括执行上述任一方面的任意一种可能的设计的方法的模块/单元。这些模块/单元可以通过硬件实现，也可以通过硬件执行相应的软件实现。
第四方面，本申请实施例中还提供一种计算机可读存储介质，所述计算机可读存储介质包括计算机程序，当计算机程序在电子设备上运行时，使得所述电子设备执行上述第一方面以及第一方面中任一种可能的设计的方法。
第五方面，本申请实施例还提供一种包含计算机程序产品，当所述计算机程序产品在终端上运行时，使得所述电子设备执行上述第一方面以及第一方面中任一种可能的设计的方法。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
本申请实施例中的具有可折叠触摸屏的电子设备，该电子设备可以为手机、pad、笔记本电脑等。以电子设备为手机为例，手机的可折叠触摸屏可以采用一个一体的柔性显示屏，也可以采用两个刚性屏以及位于两个刚性屏之间的一个柔性屏组成的显示屏。本申请实施例提供的可折叠触摸屏以包括三部分为例，如图1A、1B以及1C所示，可折叠触摸屏可包括第一屏111、第二屏112、以及连接第一屏111和第二屏113的可弯折区112。
下面结合附图对手机的可折叠触摸屏处于不同状态下的形状进行说明。
图1A示出了手机在完全展开时的形状示意图。如图1A中所示，在手机展开时，手机的壳体120展开，同时，可折叠触摸屏110也展开。其中，可折叠触摸屏110可以包括第一屏111、可弯折区112以及第二屏113，在手机的可折叠触摸屏110被完全展开时，第一屏111、可弯折区112以及第二屏113连接成一个整屏幕，此时，重力传感器可以检测到 第一屏111和第二屏113之间的夹角a为180°(实际的折叠角度可能无法达到180°，以实际上报的折叠角度为准)。
本申请实施例中，当第一屏111或者第二屏113发生旋转时，该可折叠触摸屏110可通过可弯折区112进行折叠，在手机的可折叠触摸屏被部分折叠时可参见图1B，完全折叠后的形状可参见图1C。
如图1B以及1C所示，在手机折叠时，手机的壳体120也折叠；同时，可折叠触摸屏110也折叠。图1B以及1C中示例性示出了可折叠触摸屏110在手机折叠时位于外露的一侧，应理解，手机折叠时也可以是壳体120外露，而可折叠触摸屏110位于内侧。
手机的可折叠触摸屏110从完全展开到被完全折叠的过程中，第一屏111与第二屏113之间的夹角a越来越小。如图1A所示，在可折叠触摸屏110完全展开时，第一屏111与第二屏113之间的夹角为180°。如图1B所示，在手机的可折叠触摸屏110被部分折叠时，重力传感器180E可以检测到第一屏111和第二屏113之间的夹角为40°。如1C所示，在手机的可折叠触摸屏110被完全折叠时，传感器检测到第一屏111和第二屏113之间的夹角为0度(实际的折叠角度可能无法达到0°，以实际上报的折叠角度为准)，此时第一屏111与第二屏113在手机折叠时位于外露的一侧，这样可以手机折叠时，可以同时对第一屏111和第二屏113进行操作。
本申请实施例中，当手机从完全展开时，第一屏111与第二屏113组成一整个屏幕，用户面向整个屏幕，当重力传感器检测到第一屏111旋转时，第二屏113面向用户称为主屏，第一屏111在背面称为副屏，手机可以响应于用户在副屏上进行操作，在主屏上的用户界面显示相应的提示标识，以便提示用户操作的位置。

以下实施例均可以在具有上述硬件结构的电子设备(例如手机100中实现。以下实施例将以手机100为例，结合附图对本申请实施例提供的操作提示方法进行详细介绍。
本申请的说明书和权利要求书及附图中的术语“用户界面”，是应用程序或操作系统与用户之间进行交互和信息交换的介质接口，它实现信息的内部形式与用户可以接受形式之间的转换。用户界面常用的表现形式是图形用户界面(graphic user interface，GUI)，是指采用图形方式显示的与计算机操作相关的用户界面。它可以是在电子设备的显示屏194中显示的一个图标、窗口、控件等界面元素，其中控件可以包括图标、按钮、菜单、选项卡、文本框、对话框、状态栏、导航栏、Widget等可视的界面元素。
下面介绍手机100提供的一些示例性用户界面(user interface，UI)。
本申请实施例中，在电子设备100处于完全展开状态时，电子设备100的副屏和主屏组成一个整体的屏幕，显示一个用户界面。
如图3中的3a所示，手机100的可折叠触摸屏处于完全展开的状态，手机100显示的用户界面310，该用户界面310为手机的主界面。其中，用户界面310可包括状态栏311、时间和天气小组件(widget)313、以及各种应用的图标，例如闹钟应用的图标、淘宝应用的图标、照片应用的图片、备忘录的图标等。状态栏311中可包括运营商名称(例如中国移动)、Wi-Fi图标、时间和剩余电量(如30％)等。该用户界面还可以包括可隐藏的导航栏(未在图中示出)，导航栏中可包括后退(back)键图标、主屏幕(home)键图标和前进键图标。此外，可以理解的是，在一些实施例中，状态栏311中还可以包括蓝牙图标、移动网络(例如，4G)、闹钟图标、外接设备图标等。还可以理解的是，在另一些实施例中，图3中的3a所示的用户界面310中还可以包括Dock栏312，Dock栏312中可以包括常用的应用图标，如浏览器应用的图标、设置应用的图标、微信应用的图标、相机应用的图标等。当处理器110检测到用户的手指(或触控笔等)针对某一应用的图标的触摸事件后，响应于该触摸事件，打开与该应用图标对应的应用的用户界面，并在显示屏194上显示该应用的用户界面。
在其他一些实施例中，该手机100还可以包括主屏幕键。该主屏幕键可以是实体按键，也可以是虚拟按键。该主屏幕键用于根据用户的操作，将触摸屏上显示的图形用户界面GUI返回到主屏幕的某一页面，这样可以方便用户随时查看主屏幕并对主屏幕中的控件(例如图标)进行操作。上述操作具体可以是用户按下主屏幕键，也可以是用户在短时间内连续两次按下主屏幕键，还可以是用户长按主屏幕键。在本申请其他一些实施例中，主屏幕键还可以集成指纹传感器，这样用户可以在按下主屏幕键的时候，手机100随之进行指纹采集，进而对用户身份进行确认。还有一些实施例中，主屏幕键中还可以包括屏下指纹传感器，在显示屏点亮状态下，显示屏发出的光照亮指纹纹路，指纹纹路上反射的光线被屏下指纹传感器捕获形成指纹图像，将该指纹图像与预存的指纹图像对比。在屏幕指纹解锁场景下，如果匹配成功即执行解锁，其中，比对的过程可以是提取指纹图像特征来和预存的特征模板进行比对，在相似度超过一定阈值时表明匹配成功。
可以理解的是，图3中3a仅仅示例性示出了手机100可折叠触摸屏处于完全展开的状 态上的用户界面，不构成对本申请实施例的限定。
本申请以下实施例中，以手机100折叠时主屏和副屏均位于外露的一侧为例进行介绍。
当手机100的完整的显示屏194被折叠时，副屏和主屏可以显示相同的内容，比如，主屏显示如图3中3b所示的用户界面320，该用户界面320包括的内容与用户界面310类似，比如，可以包括状态栏、时间和天气小组件(widget)、以及各种应用的图标等，具体可以参见关于用户界面310的描述。其中，副屏显示的用户界面与该用户界面320可以相同，即副屏也显示与用户界面320。副屏和主屏也可以显示不同的内容，比如主屏显示如图3中3b所示的用户界面320，副屏不显示内容。
本申请实施例中，当手机100处于折叠状态时，参见如图3中3b所示，用户面向主屏，副屏在主屏的背面，所以用户只能看到主屏上显示的内容，而看不到副屏上的内容，一般用户单手握持手机100时，为了能够支持手机重量、保持手机平衡，习惯掌心朝向副屏，大拇指在主屏的一个侧边，其它几个手指在主屏的另一侧边来握持手机，用户食指可以在副屏上进行操作。手机可以检测用户对副屏进行操作，并将该操作的结果显示在主屏上，以便于用户可以随时看到用户在副屏上的操作情况。所以，本申请实施例提供一种操作提示的方法，手机100可以在副屏提供一个显示触摸区域，手机100可以在接收到用户对副屏上的显示触摸区域进行触摸操作时，响应于该触摸操作根据位置映射关系在主屏上对应位置显示提示标识，提示标识在主屏中的显示位置与触摸操作的触摸位置关联，位置映射关系根据所述主屏与所述副屏的显示触摸区域确定。这样手机100可在接收到用户对副屏的显示触摸区域的触摸操作，在主屏显示提示标识，从而可以使得用户在看到提示标识时及时调整操作位置，进而可以避免用户因为看不到副屏而导致触摸操作所触发的位置错误，提升用户体验。
本申请实施例提供的操作提示方法可以应用于多种场景，在不同的场景下，副屏的显示触摸区域的大小也可以不同，在一些场景中，副屏的显示触摸区域可以是副屏的整个屏幕显示触摸区域。在另一些场景中，副屏的显示触摸区域也可以是副屏上的部分屏幕区域，这样用户手指只需要在小范围的显示触摸区域进行操作，就可以实现对大范围的主屏的整个显示触摸区域进行操作，便于用户操作。
为了便于理解，本申请以下实施例将以具有图2A所示结构的手机为例，结合附图2C的软件结构以及本申请实施例提供的各种应用场景，对本申请实施例提供的操作提示方法进行详细介绍。
应用场景1：手机100的主屏显示某一用户界面(比如主界面、负一屏、或者其它应用的用户界面等)的场景。在该场景下，副屏包括的显示触摸区域与主屏上的显示触摸区域存在位置映射关系，即在副屏上的显示触摸区域进行操作，可以在主屏的相应的位置显示提示标识。
以下实施例以手机100的主屏显示主界面为例，介绍通过对副屏进行操作，实现在主屏上显示提示标识的过程。
参见图4中4a，手机100的主屏上显示主界面410，该主界面410可以包括一个或多个应用图标，例如图4中4a所示的闹钟应用的图标、淘宝应用的图标、照片应用的图标、备忘录应用的图标、邮件应用的图标、设置应用的图标、微信应用的图标以及相机应用的 图标。手机100的副屏上显示有显示触摸区域420。
参见图4中4b，用户手指在副屏上的显示触摸区域420的触摸位置421进行触摸操作，手机100中的触摸器件检测到用户手指对副屏上的显示触摸区域420的触摸操作，通过TP驱动向状态检测服务上报输入事件以及副屏上的触摸位置421的坐标值，状态监测服务向显示管理服务上报输入事件以及副屏上的触摸位置421的坐标值。显示管理服务根据副屏上的触摸位置421的坐标值，以及主屏的显示触摸区域410与副屏的显示触摸区域420之间的位置映射关系，确定出副屏上的触摸位置421的坐标值在主屏上的响应位置，即图4中4b所示的提示标识411所在的位置。
下面结合图5，对主屏的显示触摸区域410与副屏的显示触摸区域420之间的位置映射关系进行说明。参见图5，为本申请提供的位置映射关系示意图。
如图5所示，副屏的显示触摸区域420的形状和主屏的显示触摸区域410的形状为均矩形，可以将矩形的显示触摸区域420上的各像素点的坐标与矩形的显示触摸区域410上的各像素点的坐标进行映射，得到位置映射关系。应理解，本申请实施例对副屏上的显示触摸区域的形状不作限制，比如显示触摸区域的形状也可以为椭圆形、菱形、圆形、或其它形状。
示例性的，手机100的副屏上的显示触摸区域420上的位置A(x，y)，根据副屏的显示触摸区域420与主屏的显示触摸区域410之间的位置映射关系，可以将位置A(x，y)映射到主屏的显示触摸区域410中位置B(X，Y)。也就是说，当用户在副屏上的显示触摸区域420的位置A(x，y)进行触摸操作，手机100可以响应于该触摸操作在位置B(X，Y)显示提示标识。其中，位置A(x，y)和位置B(X，Y)之间的映射参数可以为一个数值，比如映射参数为m，位置A(x，y)对应的位置B(mx，my)；映射参数也可以是数组，比如(m,n)，位置A(x，y)对应位置B为(mx，ny)。本申请实施例中对映射参数不作限定。
示例性的，副屏的显示触摸区域的面积小于或等于主屏的显示触摸区域的面积，这样用户手指只需要在小面积的显示触摸区域进行操作，就可以实现对大面积的主屏的整个显示触摸区域进行操作，便于用户操作。
在确定出用户手指在副屏上的触摸位置421的坐标值映射到主屏上的响应位置之后，显示管理服务将主屏上的响应位置的坐标值上报给窗口管理器，窗口管理器根据主屏上的响应位置的坐标值绘制提示标识411，并将绘制的包括提示标识411的图层以及其它图层一起发给表面管理器(SurfaceFlinger)，表面管理器对所有图层进行合并之后，下发给显示驱动，以通过显示驱动来驱动显示屏(如主屏)显示该包括提示标识411的显示界面。
本申请实施例中，提示标识411可以为箭头图标，应理解该提示标识411也可以为其它图标，比如圆点、笔等图标，此处不作限制。
用户还可以在副屏上的显示触摸区域420上进行触摸操作，实现在主屏上显示该提示标识411之后，在副屏的显示触摸区域420上滑动手指以实现将提示标识移动到想要打开的应用的图标上，然后在副屏上进行点击操作，以实现打开应用。
在打开应用之后，也可以在副屏上进行触摸操作，对主屏上显示的应用的用户界面进行操作，在主屏上显示手指在副屏上操作的位置。以下实施例以打开主屏上的照片应用为例，介绍通过对手机的副屏进行操作，实现对主屏上显示提示标识的过程。
参见图6中6a所示，手机100的主屏的显示触摸区域610显示有图片630，副屏的显 示触摸区域620为矩形，此处并不限制显示触摸区域620的具体形状，也可以为其它形状。其中，显示触摸区域610与显示触摸区域620存在位置映射关系。
示例性的，手机100检测到对副屏上的显示触摸区域620的触摸操作，手机100中的触摸器件检测到用户手指对副屏上的显示触摸区域620的触摸操作，通过TP驱动向状态检测服务上报输入事件以及副屏上的触摸位置621的坐标值，状态监测服务向显示管理服务上报输入事件以及副屏上的触摸位置621的坐标值。显示管理服务根据副屏上的触摸位置621的坐标值，以及主屏的显示触摸区域610与副屏的显示触摸区域620之间的位置映射关系，确定出副屏上的触摸位置621的坐标值在主屏上的响应位置，即图6中6a所示的提示标识611所在的位置。
在确定出用户手指在副屏上的触摸位置621的坐标值映射到主屏上的响应位置之后，显示管理服务将主屏上的响应位置的坐标值上报给窗口管理器，窗口管理器根据主屏上的响应位置的坐标值绘制提示标识611，并将绘制的包括图片630和提示标识611的图层以及其它图层一起发给表面管理器(SurfaceFlinger)，表面管理器对所有图层进行合并之后，下发给显示驱动，以通过显示驱动来驱动显示屏(如主屏)显示该包括提示标识611的显示界面。
示例的，该提示标识611为一个箭头图标，提示标识611也可以为其它形状，此处并不限定该提示标识611的具体形状。
用户手指在副屏上滑动手指的操作，在主屏上显示的提示标识611也会随着该滑动手指的操作而移动。用户可以在副屏上滑动手指至需要操作的区域，并进行操作，比如对需要操作的区域进行点击(单击、双击、多次点击)操作，该点击操作用于锁定(或者识别)住需要进行下一步操作的区域，然后再执行滑动操作，比如在主屏显示图片的场景中，该滑动操作用于放大或者缩小图片中锁定的区域，再比如，在播放视频或者播放音乐的场景中，该滑动操作用于前进或者后退，或者调节亮度变大或变小。
在主屏上显示提示标识611之后，参见图6中6b，当手机100检测到在该触摸位置622进行向上滑动的操作时，响应于该操作在主屏上显示放大的图片(如图6中6c所示)，在主屏上还可以显示提示标识613，该提示标识613用于指示用户手指在副屏上的某一点向上滑动轨迹。相应的，手机100检测到在该触摸位置622进行向下滑动的操作，可以响应于该操作在主屏上显示缩小的图片，以及用于指示用户手指在副屏上的滑动轨迹的提示标识。
在图4以及图6所示的示例中，副屏可以是触摸屏，也可以是具有指纹录入功能的指纹屏，指纹屏可以是在显示屏下方设置有指纹传感器，用于采集指纹。比如，照片应用设置有指纹验证的功能，那么在对照片进行操作之前，还需要验证触摸操作对应的输入指纹是否为指纹模板库中的指纹，在用户手指对副屏上的显示触摸区域620进行触摸操作时，指纹传感器可以采集用户手指的输入指纹，指纹传感器将采集的输入指纹上报至TEE中的指纹可信应用中，识别该指纹图像是否与安全存储器中存储的指纹模板进行匹配，得到指纹识别结果。指纹可信应用将指纹识别结果发送给指纹守护进程，之后，指纹守护进程通过指纹服务向指纹管理器上报指纹识别结果，如果指纹识别结果为匹配，那么指纹验证成功；如果指纹识别结果为不匹配，那么指纹验证失败。当指纹管理器确定指纹验证成功时，向WMS发送绘制指令，该绘制指令包用于指示绘制图谱630和提示标识611的图层，当指纹管理器确定指纹验证失败时，不向WMS发送绘制指令，也就是说，手机100对用户 在副屏的显示触摸区域上的触摸操作不进行响应，即不在主屏上显示提示标识。
通过上述图6所示的示例，用户可以单指对副屏上的显示触摸区域进行点击操作和滑动操作，也就是说，点击操作和滑动操作是单个手指执行的，从而实现通过副屏对主屏上的上显示的图片进行放大或缩小。
在其他一些实施例中，用户也可以采用双指对副屏上的显示触摸区域进行点击操作和滑动操作，从而实现对主屏上的上显示的图片进行放大或缩小。
示例性的，参见图7中7a，主屏上的显示触摸区域710显示图片730，用户可以在副屏上的显示触摸区域720的触摸位置721进行点击操作，手机100检测到点击操作，采集执行该点击操作对应的指纹A，并将该指纹A与指纹模板库中的指纹模板进行匹配，若该指纹模板库中存在指纹模板与该指纹A匹配，则手机100响应于该点击操作在主屏上显示提示标识711，该图示标识711可以为椭圆形图标。若该指纹模板库中不存在指纹模板与该指纹A匹配，手机100对该点击操作不作响应，即主屏不显示提示标识711。
之后，手机100检测到在该触摸位置722进行滑动操作，指纹传感器采集执行该滑动操作的指纹B，并将该指纹B与指纹模板库中的指纹进行匹配，若该指纹模板库中存在指纹模板与该指纹B匹配，手机100响应于该滑动操作(比如向上滑动)在主屏上显示放大的图片(如图7中7c所示)，相应的，手机100检测到在该触摸位置722进行滑动操作(比如向下滑动)，可以响应于该操作在主屏上显示缩小的图片。若该指纹模板库中不存在指纹模板与该指纹B匹配，手机100对该滑动操作不作响应。
通过上述图7所示的示例，用户可以双指对副屏上的显示触摸区域进行点击操作和滑动操作，即点击操作和滑动操作分别由两个手指执行的，从而实现对主屏上的上显示的图片进行放大或缩小。在图7所示的示例中，进行点击操作和滑动操作可以是同一手的两个不同手指，也可以是两个不同手的手指。为了操作方便，一般采用同一手的两个不同手指分别进行点击操作和滑动操作。示例的，用户可以用右手的食指进行点击操作，采用右手的中指进行滑动操作。
需要说明的是，上述图6和图7所示的示例中，是以点击操作实现锁定需要放大的位置，以向上滑动操作实现放大图片，向下滑动操作实现缩小图片为例进行说明的，还可以对需要放大的位置进行双击操作、多次点击操作、画圈等操作，来实现锁定该需要放大的位置，本申请对此不作限定。
应理解，也可以直接进行滑动操作实现放大或缩小图片，即不需要用户进行操作来锁定需要放大的位置，比如，可以在进行滑动操作时默认对图片的中心点的位置进行放大或缩小；再比如，可以在进行滑动操作时，手机100自动识别出图片中的目标对象(如图6中6a所示的人物)，然后对目标对象进行放大或缩小；又比如，手机可将滑动操作的起始点的位置进行放大或缩小。
在其他一些实施例中，也可以设置向上滑动操作用于实现缩小图片，向下滑动操作用于实现放大图片。在其他一些实施例中，可以设置点击操作用于放大图片，长按操作用于缩小图片；或者，可以设置点击操作用于缩小图片，长按操作用于放大图片。
在其它一些场景中，副屏可以支持指纹录入功能，例如指纹录入、指纹解锁等场景)，副屏中的显示触摸区域(如应用场景2中的显示触摸区域810、以及应用场景3中的显示触摸区域910)支持指纹录入功能，在开启指纹录入功能的情况下，可以通过位于副屏的 显示触摸区域的指纹传感器采集指纹。
其中，副屏的指纹录入功能可以通过多种方式触发开启。一种可能的实现方式中，当手机100处于灭屏状态时，手机100的主屏被唤醒(即主屏从灭屏状态进入亮屏状态)时，开启副屏的指纹录入功能。在另一种可能的实现方式中，手机100可以在检测到手机100被用户拿起时，开启副屏的指纹录入功能。还有一种可能的实现方式中，当手机100在检测到副屏与主屏之间的夹角小于预设阈值时，说明手机处于折叠状态，打开副屏的指纹录入功能，该预设阈值可以为180°，也可以为小于180°的任意角度，此处不作限制。
应理解，在开启指纹录入功能之后，该指纹录入功能可以一直处于开启状态。为节省功耗，当主屏从亮屏状态进入灭屏状态时，手机100关闭副屏的指纹录入功能，当主屏再次被唤醒时，手机100开启副屏的指纹录入功能。在其他一些实施例中，可以在开启指纹录入功能之后，定期关闭指纹录入功能，比如开启指纹录入功能后达到一定时长，关闭副屏的指纹录入功能，在需要使用指纹录入功能时再触发开启，也可以在手机100长时间未检测到在副屏上的操作时，关闭副屏的指纹录入功能。
本申请实施例中，当手机100的主屏处于息屏状态时，首先需要将手机的主屏唤醒，以使主屏处于亮屏状态，从而可以显示提示标识。而副屏可以处于息屏状态，也可以处于亮屏状态，在需要对副屏进行触摸操作时，副屏已开启指纹录入功能即可。
应用场景2：指纹录入场景。当手机100的用户需要在手机100中录入新指纹，可以在已打开副屏的指纹录入功能的情况下，手机100启动设置(Settings)应用，并给该设置应用打开指纹录入界面，进入指纹录入场景，应用程序层的设置应用将用于录入指纹的用户界面的相关参数通过WMS下发到表面管理器，表面管理器调用显示驱动，以驱动显示设备(如主屏)显示用于录入指纹的用户界面。另外，在设置应用进入指纹图标820的用户界面时，应用程序层的设置应用向底层系统下发指纹录入场景的命令码，例如为命令码1。指纹传感器驱动接收到该命令码1之后，驱动指纹传感器切换到采图模式，等待手指录入。
如图8中8a所示，副屏的显示触摸区域与主屏的显示触摸区域存在位置映射关系，例如，副屏上的指纹框810经过位置映射到主屏上的指纹图标820。当触摸器件检测到用户手指在副屏的显示触摸区域中的指纹框810进行触摸操作，TP驱动通过状态检测服务向显示管理服务上报输入事件以及副屏上的指纹框810的坐标值，显示管理服务可以根据主屏的显示触摸区域与副屏的显示触摸区域之间的位置映射关系，确定出指纹图标820的位置。即用户手指在副屏的指纹框810中录入指纹，可以在主屏的指纹图标820中显示提示标识821。
当指纹传感器检测到手指按压时，上报一个中断信息给指纹传感器驱动，指纹传感器驱动该指纹传感器采集指纹图像。之后，指纹传感器驱动读取指纹传感器采集到的指纹图像，并将该指纹图像以及命令码1上报至指纹管理器，指纹管理器根据命令码1，确定该指纹图像为新录入的指纹，将该指纹图像作为指纹模板存储在内部存储器中，并将已成功录入指纹的结果通过上报至设置应用。
在一些实施例中，在录入指纹的过程中，当采集的指纹不满足要求时，比如触摸位置不在指定区域内、录入指纹的面积小于预设面积等，可能会需要多次调整手指在副屏的显示触摸区域上的触摸位置，才能根据多次采集到的指纹合成得到一个完整的指纹，并将该完整的指纹作为一个指纹模板存储在手机100中的内部存储器121中，以便在指纹解锁的 场景中将采集到的输入指纹与指纹模板进行比较，并在输入指纹与指纹库中的与指纹模板匹配时，实现指纹解锁的功能。为了保证指纹模板的安全性，也可以将指纹模板存储在安全硬件中，比如安全硬件可以为安全存储器，指纹解锁的场景中在可信执行环境中验证输入指纹。
参见图8中8b，当手机100检测到用户手指触摸副屏中的指纹框810的触摸操作，该触摸操作在指纹框810的触摸区域811占用指纹框810的一部分面积，手机100在主屏上的指纹图标820显示与该触摸区域811对应的提示标识821，该提示标识821的形状与触摸区域811的形状一致，提示标识821在主屏的显示触摸区域中的位置与触摸区域811在副屏的显示触摸区域的位置满足位置映射关系，这样手机可以在主屏上提示用户在副屏中所录入的指纹的形状以及位置。
当用户看到如图8中8b所示的主屏上的提示标识821的面积小于指纹图标820的面积，而且提示标识821在指纹图标820中的位置靠中间，说明手机采集到的指纹是残缺的，所以提示标识821指示该触摸区域811采集到的指纹不满足要求，用户可以调整手指在显示触摸区域820中的触摸位置，比如在指纹图标820未被提示标识821占用的位置再次进行触摸操作，以便手机100可以采集到更完整的指纹。
在主屏显示如图8中8b所示的提示标识821之后，用户在副屏的指纹框810中偏左的位置再次进行触摸操作，参见图8中的8c，手机100响应于用户手指在副屏上的指纹框810的触摸操作(触摸位置在指纹框810的触摸区域811)，在主屏上的指纹图标820显示提示标识822，该提示标识822的形状与该触摸操作在指纹框810的触摸区域812的形状一致，且该提示标识822在主屏的显示触摸区域中的位置与触摸区域812在副屏的显示触摸区域中的位置之间满足位置映射关系。该提示标识822指示指纹的面积依然不满足录入指纹的要求，需要继续调整用户手指在副屏中的触摸位置，直到手机100在主屏上的指纹图标820显示的提示标识指示录入的指纹满足要求。
在主屏显示如图8中8c所示的提示标识822之后，用户在副屏的指纹框810中偏右的位置再次进行触摸操作，参见图8中8d，手机100响应于用户手指在副屏上的指纹框810的触摸操作(触摸位置在指纹框810的触摸区域813)，在主屏上的指纹图标820显示提示标识823，该提示标识823的形状与该触摸操作在指纹框810的触摸区域813的形状一致，且该提示标识823指示指纹的面积满足录入指纹的要求。此时，手机100可以得到完整的指纹，并将该完整的指纹作为指纹模板存储安全存储器中。
通过上述图8中8a、8b、8c以及8d可见，用户两次调整在副屏上的触摸位置从而采集到满足要求的指纹。在另一些实施例中，参见图8中8a、8b以及8d，当主屏上显示如图8中8b所示的提示标识822之后，经过一次调整在副屏上的触摸位置就可以得到如图8中8d所示的提示标识823，即指示满足要求的指纹。在其他一些实施例中，参见图8中8a以及8d，用户直接在副屏上的显示触摸区域810一次触摸操作就可以得到完整的指纹。本申请实施例仅示例性示出一次、两次、三次在副屏上的触摸区域进行触摸操作，从而采集到完整的指纹，在具体实施中，可能需要不止三次在副屏上的触摸区域调整触摸位置，才能采集到完整的指纹。
应用场景3：指纹解锁场景。本申请实施例中，指纹解锁场景可以是对处于锁屏状态的手机100进行解锁的场景，也可以在使用手机100上支付宝、微信等应用的支付功能时 需要验证指纹的场景。在指纹解锁场景中，用户可以在手机100的副屏上的显示触摸区域中进行触摸操作，并在主屏的显示触摸区域中显示提示标识，该提示标识可以指示用户手指在副屏的显示触摸区域中的触摸区域以及触摸位置。
下面以对处于锁屏状态的手机100进行解锁的场景为进行说明。
参见图9中9a，手机100的主屏的显示触摸区域显示一个指纹图标920，该指纹图标920用于显示指示用户对副屏的显示触摸区域上的指纹框910进行触摸操作时采集到的指纹。手机100的副屏显示一个指纹框910用于在检测到对指纹框910的触摸操作时采集指纹。
在需要验证指纹时，用户在副屏上的指纹框910进行触摸操作时，可能录入的指纹不全，如图9中9b所示，当手机100的指纹传感器检测到用户在副屏上的指纹框910的触摸操作时，该触摸操作在该指纹框910形成的触摸区域911，手机100响应于该触摸操作在主屏上的指纹图标920中显示提示标识921，此时提示标识921显示一个残缺的指纹，以使用户知晓该触摸操作所录入的指纹不正确，提示标识921在指纹图标920中的位置偏左，这样用户可以向右调整触摸位置进行触摸操作，以实现得到如图9中9c所示的完整的指纹。该提示标识921还可以是文字提示信息，比如提示调整指纹录入位置。
参见图9中9c，当手机100检测到用户在副屏上的指纹框910的触摸操作时，该触摸操作在该指纹框910形成的触摸区域912，手机100响应于该触摸操作在主屏上的指纹图标920中显示提示标识922，此时提示标识921显示一个完整的指纹，以使用户知晓该触摸操作所录入的指纹区域正确。然后，手机100将从显示触摸区域912采集的指纹与手机中存储的指纹模板进行比对，如果采集的指纹与指纹模板匹配，那么可以实现解锁；如果采集的指纹与指纹模板不匹配，那么解锁失败。
在解锁之后，参见图9中9d，手机100可以在主屏上用户界面930，用户界面930可以包括多个应用图标。用户可以在副屏的显示触摸区域940进行操作，并将触摸操作的位置映射到主屏上的显示触摸区域，并可以在主屏上的相应位置显示提示标识，具体过程参见图6的相关介绍，此处不再赘述。
应理解，上述指纹解锁的场景的实现过程，也可以应用于指纹应用的指纹验证的场景中，在使用支付宝、微信等指纹应用中的支付功能时，可能会采用指纹验证以代替密码验证，指纹应用的指纹验证实现过程与指纹解锁场景的实现过程类似。
