背景技术
截屏功能是手机的一项常用功能。现有的截屏方法是将手机当前屏幕显示的整个界面截取下来，并保存为图片。然而，随着手机功能的日益强大，越来越多的手机能够实现双屏，甚至是多屏显示，即屏幕在一个界面中显示多个应用程序的界面。在这种情况下，截取手机屏幕中显示的一部分界面的需求变得频繁。若仍采用现有的截屏方法，则在截整个界面后，还需要采用手机自带的编辑工具或第三方修图软件对截取的图片进行编辑，操作较为繁琐，用户体验不佳。
发明内容

以下实施例中所涉及的技术方案均可以在具有上述硬件架构和软件架构的电子设备100中实现。以下，以电子设备为手机进行举例说明。
图3A至图3H示出了一些手机的界面示意图，以下结合附图对本申请实施例提供的对界面中部分应用窗口进行截屏的方法进行详细说明。
随着手机屏幕的增大，尤其是折叠屏手机的出现，用户可以使用手机开启多个应用程序，在屏幕的一个显示界面(即第一界面)中对多个应用程序进行操作。如图3A所示，界面300为第一界面的一个示例，界面300中显示有多个应用程序的窗口。例如：浏览器应用的窗口301、微信应用的聊天窗口302、视频应用的窗口303、文档应用的窗口304以及照片应用的 窗口305。
响应于检测到截屏操作，手机可以截取整个屏幕的截图(即第一界面的截屏图片，简称第一截图)。同时，手机获取当前屏幕(即第一界面)中各个应用窗口的信息，例如：各个应用的标识、各个应用窗口的大小和坐标等信息。这样，手机可以确定出各个应用窗口在屏幕中的显示区域，也即，确定出各个应用窗口在整个屏幕的截图(即第一截图)中的位置。
在一个具体的实现方式中，响应于检测到截屏操作，手机中的截屏应用或功能可以调用SurfaceControl.screenshot截取整个屏幕的截图，即第一截图。同时，截屏应用或功能调用应用程序框架层的窗口管理服务，获取各个应用窗口的大小、坐标等信息。截屏应用或功能将第一截图和各个应用窗口的显示区域建立关联，例如：在第一截图上绘制与各个应用窗口相关联的控件。后续，截屏应用根据用户对控件的操作，确定在第一截图中保留或去掉某些应用窗口，并生成最终的截图，即第二截图。而后，将第二截图保存在图库应用中。
当然，手机也可以在检测到截屏操作后，通过调用WMS获取当前屏幕中显示的各个应用窗口的信息，建立与当前屏幕中显示的各个应用窗口一一对应的控件。而后，由用户通过这些控件选择需要保留在最终截图中的应用窗口。手机再确定需要保留的应用窗口在第一截图中的位置，从第一截图中获取需要保留的应用窗口的内容。在这种情况下，手机可以在从检测到截屏操作到确定需要保留的应用窗口在第一截图中的位置之间任一时刻截取第一界面的截图(即第一截图)。即，本申请实施例对截取第一界面的截图的时间不做限定。
其中，上述的截屏操作例如可以是用户按压物理按键的操作(例如：同时按住开机键和音量键)、用户执行预定义的手势(例如：在屏幕上三指下滑、指关节敲击屏幕)、用户在屏幕上操作相应按钮(点击通知栏中的截屏控件)等。本申请实施例对截屏操作不做具体限定。
其中，在确定各个应用窗口在屏幕中的显示区域时，可以用各个应用窗口的四个顶点坐标来表示在屏幕中的显示区域，也可以一个顶点坐标和应用窗口的大小来表示，还可以采用其他方式表示各个应用窗口在屏幕中的显示区域，本申请对此不做具体限定。
举例说明，手机屏幕正向放置时，坐标系例如是以屏幕左上角顶点(例如O点)为原点；以平行于屏幕上边缘，由手机左侧边缘指向右侧边缘的方向为X轴的正方向；以平行于屏幕左侧边缘，由手机上边缘指向下边缘的方向为Y轴的正方向。该坐标系的单位可以是像素单位，也可以是物理单位(例如：mm)，还可以是其他单位，本申请实施例对此不做具体限定。
应用窗口在屏幕中的显示区域可以用四个顶点的坐标来表示。例如：浏览器应用的窗口可以用左上角的顶点(A点)的坐标、右上角的顶点(B点)的坐标，左下角的顶点(C点)的坐标以及右下角的顶点(D点)的坐标表示。其他应用窗口的显示区域的表示方式类似，不再赘述。或者，应用窗口在屏幕中的显示区域还可以用一个顶点和窗口大小来表示。例如：浏览器应用的窗口可以用左上角的顶点(A点)的坐标，以及窗口的大小(例如：M*N)。其他应用窗口的显示区域的表示方式类似，不再赘述。
需要说明的是，坐标系的原点也可以是屏幕上其他任意一点，例如：屏幕中心，X轴和Y轴的方向也可以是其他方向，本申请实施例对坐标系不做限定。
在确定了各个应用窗口在屏幕中的显示区域后，也可以在整个屏幕的截图(即第一截图)中确定各个应用窗口的显示区域。而后，将各个应用窗口的显示区域关联相应的控件。这样，用户可以通过操作这些控件，对各个应用窗口的显示区域进行相应的选择。例如：选择在第一截图中保留某个应用窗口的显示区域，或者，选择在第一截图中去掉某个应用窗口的显示区域等。即，在本申请中，手机可以根据用户的选择，在整个屏幕的截图中保留用户想要显示的应用窗口的内容，或者去掉用户不想显示的应用窗口的内容。也即，本申请实现对整个 屏幕中的特定区域的快速截屏。
在一些实施例中，在截取整个屏幕的截图(即第一截图)后，可以在屏幕上显示该第一截图(即第二界面)，并在第二界面上显示有关联各个应用窗口的一些控件，例如选择控件、删除控件等。其中，选择控件可用于选择应用窗口，即选择需要保留在最终截图中的应用窗口。删除控件可用于去选择应用窗口，即选择不需要保留在最终截图中的应用窗口。这样，用户可以直接操作各个应用窗口对应的控件，来选择最后截图中保留的应用窗口的内容，或者，选择最后截图中需要删除的应用窗口的内容。可选的，手机在显示第二界面时，可以将第一截图进行适当比例的缩小，以便用户可以区分第一界面和第二界面。可选的，在手机截取第一截图时，手机也可以播放例如拍照声等提示音，提示用户已经对第一界面进行截屏。
其中，与各个应用窗口关联的控件可以显示在各个应用窗口的显示区域上，也可以显示在各个应用窗口的显示区域的周围。或者，也可以列表形式显示在其他区域，本申请实施例对控件的显示方式和位置等均不做限定。
例如：如图3A所示，界面306为第二界面的一个示例。界面306中显示有缩小后的第一截图307。在缩小后的第一截图307中，各个应用窗口的显示区域也进行了适当的缩小。并且，在界面306上还显示有各个应用窗口对应的控件。一些示例中，手机在截取第一界面的截图后，也可以默认第一界面中的各个应用程序均未被选中，即默认为用户在最终的截图中不保留任何应用窗口的内容。而后，用户可以通过点击选择控件来选择想要保留某些应用窗口的内容。又一些示例中，手机在截取第一界面的截图后，可以默认第一界面中的各个应用程序均被选中，即默认为用户在最终的截图中想要保留第一界面中的各个应用窗口的内容。而后，用户可以通过点击删除控件来选择去掉某些应用程序的窗口。
举例来说，文档应用对应的显示区域上显示有删除控件308。当手机检测到用户点击删除控件308，手机将文档应用的窗口所在显示区域显示为能够区分于其他应用窗口的颜色，例如灰色。或者，采用其他能够区分其他应用窗口的方式显示文档应用的窗口。这表示用户选择在最终的截图中去掉该应用窗口的内容，即最终的截图中不显示该应用窗口的内容。
可选的，界面306上还可以显示一些其他控件，例如：合并控件311、分离控件310、反选控件312、编辑控件313等。其中，合并控件311用于指示将选中的多个应用程序的窗口的内容显示在一个截图(即一张图片)上，在一个实施例中，该多个应用程序的窗口在该一张截图上不重叠。即，合并控件311用于实现将选中的多个应用程序的窗口内容合并显示的功能，以下简称合并功能。分离控件310用于指示将选中的多个应用程序的窗口内容显示在多个截图(即多张图片)上，例如：每个截图中仅显示一个应用程序的窗口内容。即，分离控件310用于实现将选中的多个应用程序的窗口内容分开显示的功能，以下简称分离功能。反选控件312用于快速的将当前截图中选中的应用程序切换为未选中状态，将未选中的应用程序切换为选择状态。编辑控件313用于指示将当前的截图切换到编辑状态，可对当前截图进行例如剪裁、涂鸦、马赛克、转发等操作。
如图3B所示，界面314为手机检测到用户点击删除控件308后显示的界面。可见，删除控件308对应的文档应用的窗口与其他应用的窗口显示方式不同，图中以阴影的方式进行区分。可选的，被选择删除的应用窗口还可以关联添加控件，例如：添加控件315，以便用户通过该添加控件将该应用窗口添加回来，即，在最终的截图中显示该应用窗口的内容。
可选的，在选择了要显示的应用窗口(或者选择了不要显示的应用窗口)后，还可以选择将选中的应用窗口合并显示在一张截图上，还是将选中的应用窗口分别显示在多张截图上。即，选择合并功能或分离功能。
首先，介绍合并功能。
在第二界面上，若检测到用户点击合并控件311，则手机根据用户当前的选择，生成最终的截图(即第二截图)，该第二截图中显示有用户当前选择要显示的多个应用窗口的内容。第二截图与第一截图的大小相同，第二截图中各个应用程序窗口的大小也与第一截屏中相应的应用程序窗口的大小相同。
例如：第二界面为界面314时，界面314中，用户选择删除文档应用的窗口后，响应于检测到用户点击合并控件311，手机生成第二截图。该第二截图中包括有浏览器应用的窗口、微信的聊天窗口、视频应用的播放窗口、以及图库应用的窗口。如图3B所示，图片316为手机生成的第二截图的一个示例。在该截图中未显示有用户选择去掉的应用窗口(即文档应用的窗口)的内容。在一个具体的实现方式中，可以对第一截图中，用户选择去掉的应用窗口(例如文档应用的窗口)的显示区域的像素值进行修改，使得该显示区域显示为黑色、或灰色、或白色、或马赛克等特定图案。本申请实施例中对此不做具体限定。
需要说明的是，在第二截图中显示多个应用窗口的内容时，可以保留各个应用窗口原来的位置，即各个应用窗口的显示区域不变。也即，第二截图的大小与第一界面的大小相同，各个应用窗口在第二截图中的位置，与各个应用窗口在第一界面中的位置相同。在另一个具体的实现方式中，手机可以自动根据用户的选择，将第一截图中用户未选择要保留的应用窗口(或者用户选择要删除的应用窗口)从第一截图中裁剪掉，即得到第二截图。即，第二截图的大小小于第一界面的大小。但各个应用程序之间在第二截图中的相对位置，与各个应用程序之间在第一界面中的相对位置相同。
可选的，手机也可以自动对某些应用窗口的位置进行调整，使得第二截图上各个应用窗口的布局更加紧凑与美观，方便后续对第二截图进行其他处理，例如：裁剪、压缩等。用户还可以通过例如拖动等方式手动对某些应用窗口的位置进行移动。本申请实施例对调整应用窗口的位置的方法不做具体限定。在一个具体的实现方式中，手机可以自动根据用户的选择，将用户选择要保留的各个应用窗口分别裁剪下来，然后根据屏幕的大小，对裁剪下来的各个应用窗口的位置进行重排，合成第二截图。即，各个应用窗口在第二截图中的大小，与各个应用窗口在第一界面中的大小相同，但各个应用窗口在第二截图中的位置，与各个应用窗口在第一界面中的位置不同。可选的，手机也可以根据屏幕的大小，对裁剪下来的各个应用窗口的位置以及大小进行重排，合成第二截图。即，各个应用窗口在第二截图中的大小和位置，与各个应用窗口在第一界面中的大小和位置均不同。
例如：如图3C所示，用户在界面317上选择要保留的应用窗口有浏览器应用的窗口，以及视频应用的播放窗口。那么，在检测到用户点击合并控件后，手机生成包含有多个应用窗口的内容的第二截图。第二截图例如可以是图片318。即，第二截图上各个应用窗口的位置与第一截图上相应的应用窗口的大小和位置均相同。第二截图例如也可以是图片319。即，第二截图上各个应用窗口大小与第一截图上相应的应用窗口的大小相同，但部分应用窗口的位置与第一截图中相应的应用窗口的位置可以不同，即对某些应用窗口的位置进行了调整。例如：将原来不相连的应用窗口，集中在一起显示，使得第二截图中各个应用窗口布局更加紧凑。可选的，手机也可以自动将第二截图中未显示有应用窗口的区域裁剪掉。即，第二截图的图片大小小于第一截图。第二截图例如还可以是图3D所示的图片332，即对某些应用窗口的位置和大小均进行调整。比如，将视频应用的窗口的长和宽按照一定比例进行放大，使得第二截图中各个应用窗口的排列更加紧凑和美观。
又例如：如图3E所示，用户在界面320上选择要保留的应用窗口有浏览器应用的窗口， 微信的聊天窗口以及视频应用的播放窗口。那么，在检测到用户点击合并控件后，手机生成包含有多个应用窗口的内容的第二截图。第二截图例如可以是图片321。图片321上，各个应用窗口保留各自在第一截图上的位置。第二截图例如也可以是图片322。图片322上，对某些应用窗口的位置进行了调整，使得第二截图上的布局更加紧凑。有利于后续对第二截图进行其他处理，比如剪裁、压缩等处理。可选的，手机也可以自动将第二截图中未显示有应用窗口的区域裁剪掉。即，第二截图的图片大小小于第一截图。
再来，介绍分离功能。
在第二界面上，若检测到用户点击分离控件310，则手机根据用户当前的选择，生成多个第二截图，其中每个第二截图中仅显示用户选择的一个应用窗口的内容。可选的，每个第二截图的大小均小于第一截图的大小。
例如：如图3F所示，界面323为一个第二界面的一个示例。用户选择需要在第二截图中显示的应用窗口有浏览器应用的窗口、以及微信应用的聊天窗口。响应于检测到用户点击分离控件310，手机自动生成两张第二截图，例如图片324和图片325。其中，图片324显示浏览器应用的窗口，且图片324的大小与浏览器应用的窗口大小一致。图片325显示微信应用的聊天窗口，且图片325的大小与微信应用的聊天窗口大小一致。
在另一些实施例中，分离功能还可以和滚屏功能结合使用。例如：第二界面中还可以显示关联各个应用程序的滚屏控件。即，可实现对选中滚屏功能的应用窗口进行滚动截屏，得到该应用窗口的完整界面的截图。
例如：如图3G所示，界面326为第二界面的一个示例。该界面326上，用户选择要显示的应用窗口有浏览器应用的窗口和微信的聊天窗口。用户在点击了网易新闻应用的窗口关联的滚屏控件309，以及分离控件310后，手机生成两张第二截图，分别为图片327和图片328。可见，图片327显示了网易新闻应用当前窗口的完整界面。图片328显示了微信应用的当前聊天窗口的界面。
其中，手机在生成图片327时，可以自动对选中滚屏功能的应用窗口进行滚屏操作，并在执行滚屏操作的过程中，截取该窗口整个界面的截图。
分离功能中其他内容可参考合并功能中的相关内容的描述，这里不再赘述。
可以理解的是，手机可以在用户触发截屏操作时，可默认选择合并功能或分离功能中任一种方法生成第二截图，也可以同时采用合并功能和分离功能生成第二截图，本申请实施例对此不做限定。
可选的，若手机在预设时间段内一直未检测到用户点击合并控件311或者分离控件310，则自动根据用户选择中应用程序，默认采用合并功能或分离功能生成第二截图。可选的，若手机检测到用户连续触发截屏操作时，也可以默认采用合并功能或分离功能生成第二截图。本申请实施例对此不做限定。
可选的，还可以是检测到用户执行不同的截屏操作，手机默认选择不同的方法生成第二截图。例如：用户按压锁屏键和音量加键时，手机默认采用合并功能的方法生成第二截图。用户按压锁屏键和音量减键时，手机默认采用分离功能的方法生成第二截图。又例如：用户按键锁屏键和音量按键时，手机默认采用合并功能的方法生成第二截图。用户通过点击通知栏下的截屏控件时，手机默认采用分离功能的方法生成第二截图。
此外，手机在生成第二截图时，还可以显示提示信息，例如正在保存照片。
一些示例中，手机生成第二截图后，自动将第二截图保存在图库应用中，手机自动回到截屏前的界面，即显示第一界面。另一些示例中，手机在生成第二截图后，自动将第二截图 保存在图库应用中，并在显示的第一界面中显示第二截图的缩略图。若用户点击第二截图的缩略图时，手机显示第二截图的编辑界面，即可以对第二截图进行例如：剪裁、涂鸦、转发等操作。可选的，在对第二截图进行编辑后，手机回到第一界面。若用户点击第一界面中非第二截图的缩略图时，第二截图的缩略图消失，即手机显示第一界面。本申请实施例对此不做具体限定。
由此可见，本申请实施例提供了的截屏方法中，手机可以自动识别出屏幕中的多个应用窗口的显示区域，并可以根据用户的选择，自动截取用户选择需要的应用程序窗口的内容，能够实现快速截取界面中特定区域的截图，满足用户个性化需求，提升用户体验。
以上实施例是以手机屏幕铺满了应用窗口，即第一界面由多个应用窗口组成为例进行说明的。在另一些实施例中，手机屏幕可能没有被应用窗口铺满，即第一界面中除应用窗口外，还可以显示部分桌面、状态栏、停靠栏(dock)等。在这种情况下，屏幕中非应用窗口的显示区域可以作为一个或多个独立的显示区域。用户也可以选择在最终的截图中是否保留这一个或多个独立显示区域。也就是说，该一个或多个独立的显示区域也可以关联一个或多个控件，例如：删除控件、添加控件等。
例如：如图3H所示，界面329为第一界面的另一个示例。在该界面329上，显示有多个应用程序的窗口和一部分桌面330。在检测到用户执行截屏操作时，手机对当前的屏幕进行截屏，并获取当前屏幕中各个应用程序的信息，确定出各个应用程序的显示区域。手机还可以根据获取的各个应用程序的显示区域的信息，确定出第一界面中部分桌面所在的显示区域。而后，手机可以显示第二界面，即，界面329。该界面329上各个应用窗口的显示区域都关联有删除控件，并且显示桌面的区域也关联有删除控件331。即，用户也可以通过操作删除控件331，选择是否在第二截图中保留该部分桌面的内容。
上文详细介绍了对多个应用窗口的界面进行一次截屏的过程。考虑到这样的场景，用户在进行一次截屏后，可能需要对该界面上某些应用窗口的内容进行一些操作，然后再次对这些应用窗口进行截屏。于是，本申请实施例还提供了一种可以在截屏过程中对下次仍需要截屏的应用窗口进行锁定的操作。那么，用户再次截屏时，可以默认选择已锁定的应用窗口。
图4A至图4D为手机的又一些界面示意图，以下结合附图对本申请实施例提供的锁定方案进行详细说明。
用户在第一界面上，执行截屏操作(为了便于说明，将本次截屏操作记为第一次截屏操作)，手机显示第二界面。在第二界面上，还显示有与各个应用窗口关联的锁定控件，用户可以通过该锁定控件选择在下一次截屏需要保留的应用窗口。即，下次截屏时，默认锁定的应用窗口的内容为要保留在最终的截图中，默认未锁定的应用窗口的内容为不需要保留在最终的截图中。
一些实施例中，手机可以默认本次截屏时要保留的应用窗口为锁定状态，默认本次截屏时不需保留的应用窗口为非锁定状态，也可称为解锁状态。而后，用户可以通过操作锁定控件来切换应用窗口的锁定状态和解锁状态。
例如：如图4A所示，界面400为第二界面的一个示例。在界面400中，在各个应用窗口的显示区域还显示有相应的锁定控件。用户可以通过各个应用窗口关联的锁定控件选择需要锁定的应用窗口。例如：浏览器应用的窗口、微信应用的聊天窗口以及图库应用的窗口为锁定状态，视频应用的窗口和文档应用的窗口为解锁状态。响应于用户点击合并控件，手机生成本次的截屏图片，例如：图片402。图片402中显示有浏览器应用的窗口、微信应用的聊天窗口图库应用的窗口、以及视频应用的窗口。为了便于将本次截屏与后续的截屏进行区 分，将本次截屏记为第一次截屏。
完成第一次截屏后，手机回到第一界面。用户在第一界面上继续操作，例如：通过浏览器应用上查看了其他新闻，微信应用的聊天窗口有新的信息，得到第三界面。当检测到用户在第三界面上执行截屏操作(记为第二次截屏操作)，手机截取第三界面的截图。将第三界面的截图适当缩小后进行显示，即显示第四界面。
例如：如图4B所示，界面403为第四界面的一个示例。界面403上默认上次截屏(即第一次截屏)时锁定的应用窗口为本次截屏(即第二次截屏)需要保留的应用窗口，默认上次截屏时未锁定的应用窗口为本次截屏不需要保留的应用窗口。即，浏览器应用的窗口，微信应用的聊天窗口，以及图片应用的窗口默认为第二次截屏需要保留的应用窗口。当然，用户也可以通过删除控件去掉不再想保留的应用窗口，或者，通过添加控件恢复想保留的应用窗口。这里以用户未对默认保留的应用窗口进行修改为例，进行说明。响应于用户在第三界面点击合并控件，手机生成新的截图，例如：图片404。图片404中显示有浏览器应用的窗口内容，微信应用的聊天窗口的内容，以及图库应用的窗口的内容。可选的，手机也可以自动将未显示有应用窗口内容的区域裁剪掉，有利于减少截图的大小。
用户还可以通过操作个应用窗口关联的锁定控件，来切换某个应用窗口的锁定状态和锁定状态。或者，用户还可以通过退出某个已锁定的应用窗口，来将该应用窗口由锁定状态切换到非锁定状态。本申请对此不做限定。
例如：仍然以界面403为第四界面为例进行说明。如图4C所示，界面403中显示图库应用的窗口为锁定状态。响应于用户点击锁定控件401，手机将图库应用的窗口切换为解锁状态，如界面405所示。也就是说，当手机完成第二次截屏后，若再次检测用户执行截屏操作(记为第三次截屏操作)时，手机默认图库应用的窗口为第三次截屏时不需要保留的应用窗口，即默认第三次截屏生成的截图中不显示图库应用的窗口内容。
需要说明的是，在锁定应用窗口后，应用窗口的位置发生变化时，并不影响锁定状态。
例如：仍然以界面403为第四界面为例进行说明。在手机完成第二次截屏时，回到第三界面。第三界面中的应用窗口的排列与第四界面中的排列相同。若用户将部分应用窗口的位置进行移动，并不影响应用窗口被锁定状态。比如，在第三界面上，用户将微信应用的聊天窗口与图库应用的窗口进行调换。手机再次检测截屏操作(即第三次截屏操作)时，如图4D所示，手机显示界面406，在该界面406上，浏览器应用的窗口、图库应用的窗口、以及微信应用的聊天窗口均为默认在第三次截屏时需要保留的应用窗口，且均为锁定状态。响应于用户点击合并控件，手机生成第三次截屏的截图，即图片407。
以下，对锁定部分应用窗口的内部实现进行示例性说明。
检测到用户在第一界面上执行截屏操作，手机显示第二界面。用户可以在第二界面上通过锁定控件选择锁定的应用窗口。此时，手机(例如可以是截屏应用)记录下处于锁定状态的应用窗口的标识(或是应用程序的标识，例如应用程序的包名等)。也就是说，手机中维护有处于锁定状态的应用程序或应用程序的窗口的列表。
而后，手机完成本次截屏后，回到第一界面。用户继续在第一界面上进行操作，得到第三界面。手机检测到用户在第三界面上再次执行截屏操作后，手机一方面截取第三界面的整个界面的截图，并获取第三界面中各个应用程序的标识、坐标、位置等信息。另一方面，手机读取存储的处于锁定状态的应用程序或应用程序的窗口的列表。
而后，将列表中包含的应用程序窗口与本次获取的各个应用程序的窗口(即第三界面中显示的各个应用程序窗口)进行比对，将两者中重合的应用程序窗口设置为默认需要在最终 截图中保留的应用窗口。
若列表中包含的某个应用程序窗口，但第三界面中没有显示该应用窗口，表示用户已退出该应用程序。则手机可以更新该列表，删除该应用程序窗口的标识，或者，将给应用程序窗口设置为非锁定状态。当然，在另一些实施例中，也可以在处于锁定状态的应用窗口退出时，手机就即时更新该列表，删除已退出的应用程序窗口的标识，或者，将已退出的应用程序窗口设置为非锁定状态。
若第三界面中显示有某个应用窗口，但列表中没有包含的该应用程序窗口，表示该应用程序可能是用户新打开的应用程序，或者是未锁定的应用程序。
而后，用户还可以通过在第三界面上操作锁定控件对应用窗口的锁定状态进行切换，手机根据用户的操作，及时更新列表，以便下次截屏调用。
再有，考虑另一些场景中，用户可能会经常对某些应用的窗口进行截屏，例如短信应用、微信的窗口、视频应用的窗口、浏览器应用的窗口等。用户也可以对经常截屏的应用进行配置，即将经常截屏的应用配置为锁定状态。这样，用户在执行截屏操作时，手机可以将当前屏幕中包含的用户经常截屏的应用窗口默认设置为需要保留的窗口。这样，有利于提高截屏效率，提升用户体验。在该场景下，经常截屏的应用的锁定状态的解除，由用户进行设置。
在一个具体的实现方式中，用户可以通过系统设置或者截屏应用的设置，选择经常截屏的应用设置为锁定状态。后续，用户也只能通过系统设置或截屏应用的设置，将设置的锁定状态切换为解锁状态。
可以理解的是，用户可以通过执行不同的截屏操作，选择不同场景下的锁定方法。例如：用户按键锁屏键和音量按键时，手机默认采用第一种场景下的锁定方法，设置默认选择保留的应用窗口。用户通过点击通知栏下的截屏控件时，手机默认采用第二种场景下的锁定方法，设置默认选择保留的应用窗口。
前述实施例都是在检测到用户的截屏操作后，先截取整个屏幕的截图(例如：第一截图)，然后根据用户对应用窗口的操作，从整个屏幕的截图中选择保留或删除一个或多个应用窗口，得到最后的截图(例如：第二截图)。在另一些实施例中，也可以不用截取整个屏幕的截图，可以直接根据用户对应用窗口的操作，确定出用户需要保留或删除的应用窗口，直接获取需要保留的一个或多个应用窗口的截图，得到最后的截图。
示例的，响应于检测到用户在第一界面上截屏操作，手机中的截屏应用或功能可以调用应用程序框架层的窗口管理服务，获取当前屏幕中显示的应用窗口的标识(或应用程序的标识)，例如APP1的标识、APP2的标识和APP3的标识。而后，手机可以在第一界面上或者在新的界面上绘制与当前各个应用窗口关联的控件，例如：与APP1关联的第一控件，与APP2关联的第二控件，以及与APP3关联的第三控件。用户可以通过操作这些控件对各个控件对应的应用窗口进行选择或去选择的操作。其中，选择操作，是指选择在最终的截图中需要保留的应用窗口。去选择，是指选择在最终的截图中不需要保留的应用窗口。
根据用户的各个应用窗口对应的控件的操作，确定需要在最终的截图中保留的应用窗口。例如：用户选择的应用窗口有APP1和APP2，或者，用户去选择的应用窗口为APP3。那么，手机可以确定在最终的截图中需要显示APP1和APP2的应用窗口，不用显示APP3的应用窗口。
而后，手机可以根据选择的应用窗口的标识，或应用程序的标识(如：APP1和APP2的标识)从WMS中获取相应的应用窗口的信息(例如：APP1的应用窗口的大小、坐标等信息、以及APP2的应用窗口的大小、坐标等信息)。此外，手机还可以根据选择的应用窗口的标识 分别获取各个应用中获取各个应用的顶层视图(Decor View)的缓存(cache)，即获取各个应用窗口的界面内容(例如：APP1和APP2的界面内容)。例如：从APP1中获取顶层视图的缓存，即得到APP1的窗口中显示的内容。从APP2中获取顶层视图的缓存，即得到APP2的窗口中显示的内容。可以注意到的是，在一实施例中，可以不用获取用户去选择的应用窗口的界面内容，例如：不用获取APP3的窗口中的显示内容。
再根据获取到的各个应用窗口的大小、坐标等信息(该各个应用窗口的大小、坐标等信息用于表征在第一界面中各个应用窗口的大小以及位置)，各个应用窗口的界面内容绘制最终的截图。一些示例中，得到的各个应用窗口的截图是保留了原界面中各个应用窗口的大小和位置。
若用户选择合并功能，则最终的截图中包括有选择保留的多个应用窗口的内容。一些示例中，最终的截图的大小与第一界面的大小相同，这多个应用窗口在最终的截图中的位置和大小，与这多个应用窗口在第一界面中的位置和大小均相同。即，采用获取到的各个应用窗口的大小、坐标等信息呈现各个应用窗口的界面内容。另一些示例中，最终的截图的大小与第一界面的大小相同，这多个应用窗口在最终截图中的位置和大小，也可以与这多个应用窗口在第一界面中的位置和大小有所不同。即，根据获取到的各个应用窗口的大小、坐标等信息，进行适当的调整后，呈现各个应用窗口的界面内容。例如：将获取到的APP1的大小按照一定比例进行缩放，作为APP1窗口在最终截图中的实际大小。此时，最终截图中APP1的窗口的大小与第一界面中APP1的大小不同。又例如：将获取到的APP1的坐标进行修改，如APP1应用窗口的左上角的顶点A点变换为A ’，APP1的大小保持不变。那么，APP1的窗口在该截图中的位置，与APP1的窗口在第一界面中的位置不同；APP1的窗口在该截图中的大小，与APP1的窗口在第一界面中的大小不同。另一些示例中，最后的截图的大小也可以和第一界面的大小不同，那么各个应用窗口在最后的截图中的相对位置，与各个应用窗口在第一界面中的相对位置可以相同，也可以不同。
需要说明的是，各个应用窗口在最终截图中的大小和位置，与各个应用窗口在第一界面中的大小和位置之间的关系可以参考前述实施例中的描述，这里不再赘述。
若用户选择的分离功能，则最终的截图为多张图片，其中每一张图片中包含有至少一个用户选择的需要保留的应用窗口的内容。仍然以第一界面中显示有APP1、APP2和APP3的窗口，且用户选择在最终截图中保留APP1、APP2为例，则最终的截图包括两张图片，一张图片显示有APP1的窗口内容，另一张图片显示有APP2的窗口内容。在一些示例中，最终截图的大小与第一界面的大小相同，则手机可以根据每个选择保留的应用窗口的大小、坐标等信息，以及每个应用窗口的界面内容进行分别绘制，得到多张图片，即为最后的截图。这样，各个应用窗口在最后截图中的位置和大小，与各个应用窗口在第一界面中的位置和大小相同。例如：根据前面获取到的APP1的大小、位置等信息，以及APP1的窗口内容进行绘制，得到一张包括APP1的窗口内容的截图。类似的，可以得到一张包括APP2的窗口内容的截图。在又一些示例中，考虑在最终截图中只包括有一个应用窗口，也可以对该应用窗口的位置和/或大小进行调整。比如，手机可以根据每个选择保留的应用窗口的大小，以及每个应用窗口的界面内容进行分别绘制，得到最后的截图。即，可以默认各个应用窗口在最后截图的特定位置(例如：居中位置)。此时，各个应用窗口在最后的截图中的大小，与各个应用窗口在第一界面中的大小相同；但各个应用窗口在最后的截图的位置，与各个应用窗口在第一界面中的位置不同。又比如，手机可以根据每个选择保留的应用窗口的界面内容进行分别绘制，得到最后的截图。即，可以默认各个应用窗口在最后截图的特定位置，以及预设大小。 此时，各个应用窗口在最后的截图中的大小和位置，与各个应用窗口在第一界面中的大小和位置均不同。在另一些示例中，最后的截图的大小也可以和第一界面的大小不同。
需要说明的是，各个应用窗口在最终截图中的大小和位置，与各个应用窗口在第一界面中的大小和位置之间的关系可以参考前述实施例中的描述，这里不再赘述。
在该实施例中，其他内容可参考前述实施例的相关内容的描述，不再赘述。
