Description

显示页面的刷新方法、阅读器及计算机存储介质
相关申请的交叉参考
本申请要求于2019年12月30日提交中国专利局、申请号为201911392605.9、名称为“显示页面的刷新方法、阅读器及计算机存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及墨水屏显示技术领域，具体涉及一种显示页面的刷新方法、阅读器及计算机存储介质。
背景技术
墨水屏阅读设备是指使用电子墨水屏(E-ink或Electronic Paper Display，简称EPD)的电子阅读设备。其中，电子墨水屏是一种本身不发光而依靠外界反光实现显示效果的屏幕，其显示效果与纸质材料极为类似，因此可比拟纸质材料阅读的体验。电子墨水屏由许多微囊组成，每个微囊里包含多个黑色粒子和多个白色粒子，两者各带相反电荷。当需要在屏幕上显示黑色内容时，通过电压驱动黑色粒子向上移动到屏幕顶部(也即从底部向屏幕方向移动)，当显示白色内容时，通过电压驱动白色粒子向上移动到屏幕顶部(也即从底部向屏幕方向移动)。
墨水屏阅读设备在进行刷新显示时，通过采用全局刷新模式消除屏幕残影问题，全局刷新是指，将屏幕上所有像素点的墨水颗粒从当前位置刷新到全白位置，接着刷新到全黑位置，然后根据下一帧图像需要显示的内容，将墨水粒子从全黑位置刷新到不同的灰阶位置上。换言之，在全局刷新时，显示的内容变换时，墨水屏以像素为单位，每个像素会经历一个白－黑－白的颜色变化过程，以保持屏幕的对比度。
然而，发明人在实施本公开实施例的过程中发现：全局刷新模式虽然能够有效消除残影问题，但是由于墨水粒子有一个从当前灰度到全白到全黑再到下一帧灰度位置的刷新过程，所以刷新速度比较慢，尤其对于菜单、弹窗等页面元素的显示，不能满足快速刷新的要求。
发明内容
鉴于上述问题，提出了本公开以便提供一种克服上述问题或者至少部分地解决上述问题的显示页面的刷新方法、阅读器及计算机存储介质。
根据本公开的一个方面，提供了一种显示页面的刷新方法，包括：
响应于接收到的页面刷新请求，获取待显示页面中包含的多个页面视图 的视图布局信息；
当根据视图布局信息确定多个页面视图之间存在重叠区域时，针对存在重叠区域的页面视图的视图尺寸进行调整，以消除页面视图之间的重叠区域；
针对待显示页面中包含的多个调整后的页面视图，确定与多个调整后的页面视图相对应的至少一个页面刷新区域，通过多个刷新通道并行刷新各个页面刷新区域。
根据本公开的另一方面，提供了一种阅读器，包括：处理器、存储器、通信接口和通信总线，处理器、存储器和通信接口通过通信总线完成相互间的通信；
存储器用于存放至少一可执行指令，可执行指令使处理器执行如下操作：
响应于接收到的页面刷新请求，获取待显示页面中包含的多个页面视图的视图布局信息；
当根据视图布局信息确定多个页面视图之间存在重叠区域时，针对存在重叠区域的页面视图的视图尺寸进行调整，以消除页面视图之间的重叠区域；
针对待显示页面中包含的多个调整后的页面视图，确定与多个调整后的页面视图相对应的至少一个页面刷新区域，通过多个刷新通道并行刷新各个页面刷新区域。
根据本公开的又一方面，提供了一种非易失性计算机可读存储介质，非易失性计算机可读存储介质中存储有至少一可执行指令，可执行指令使处理器执行如下操作：
响应于接收到的页面刷新请求，获取待显示页面中包含的多个页面视图的视图布局信息；
当根据视图布局信息确定多个页面视图之间存在重叠区域时，针对存在重叠区域的页面视图的视图尺寸进行调整，以消除页面视图之间的重叠区域；
针对待显示页面中包含的多个调整后的页面视图，确定与多个调整后的页面视图相对应的至少一个页面刷新区域，通过多个刷新通道并行刷新各个页面刷新区域。
根据本公开的再一方面，还提供了一种计算机程序产品，该计算机程序产品包括存储在上述非易失性计算机可读存储介质上的计算程序。
根据本公开的显示页面的刷新方法、阅读器及计算机存储介质，对于接收到的页面刷新请求，依据待显示页面包含的多个页面视图的视图布局信息 分析出多个页面视图之间是否存在重叠区域，并针对存在重叠区域的页面视图的视图尺寸进行调整，以消除页面视图之间的重叠，后续则可针对调整后的页面视图划分的页面刷新区域，采用多个刷新通道进行并行刷新。由此可见，本公开方案通过对待显示页面中多个页面视图的视图尺寸进行调整，使多个页面视图之间不存在重叠区域，进而可利用多个刷新通道对多个页面刷新区域同时进行刷新，相较于现有技术中针对存在重叠区域的页面视图，只能利用全刷模式依次进行刷新的方式，可以极大地提高刷新显示的效率。

本公开的较佳实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
图1示出了本公开显示页面的刷新方法实施例的流程图。该方法应用于墨水屏阅读器。如图1所示，该方法包括以下步骤：
步骤S110：响应于接收到的页面刷新请求，获取待显示页面中包含的多个页面视图的视图布局信息。
其中，页面刷新请求是指显示新的页面内容的请求。
具体地，在墨水屏接收到页面刷新请求时，获取待显示页面中包含的多个页面视图的视图布局信息，其中，待显示页面是指新的页面内容所在的页面，并且，每个待显示页面通常由多个页面视图组成，每个页面视图用于显 示不同的内容，例如，状态栏视图用于显示电量、时间、网络等内容，菜单栏视图则可以显示亮度等设置信息；以及，视图布局信息则是反映构成该待显示页面的多个页面视图的位置的信息。
步骤S120：当根据该视图布局信息确定该多个页面视图之间存在重叠区域时，针对存在重叠区域的页面视图的视图尺寸进行调整，以消除页面视图之间的重叠区域。
其中，两个页面视图之间存在重叠区域是指该两个页面视图分别覆盖的视图区域中存在部分相同的区域。
具体地，在确定多个页面视图中至少两个页面视图之间存在重叠区域时，则针对该至少两个页面视图进行重叠区域的消除，直至任意两个页面视图均不存在重叠区域为止。在消除的过程中，通过调整视图尺寸，不断缩小重叠区域。
步骤S130：针对待显示页面中包含的多个调整后的页面视图，确定与多个调整后的页面视图相对应的页面刷新区域，通过多个刷新通道并行刷新各个页面刷新区域。
在针对具有重叠区域的页面视图的视图尺寸进行调整后，则得到经调整处理后的多个页面视图(其中可能存在部分页面视图的视图尺寸并未改变)。将调整后的多个页面视图的视图区域划分为多个页面刷新区域，其中，一个页面刷新区域覆盖至少一个页面视图的视图区域；并且，通过并行的多个刷新通道对多个页面刷新区域同时进行刷新处理，将页面刷新区域覆盖的至少一个页面视图的视图元素刷新显示在墨水屏上。由于调整后的多个页面视图之间不存在重叠区域，则划分出的页面刷新区域之间也不存在重叠区域，进而可通过多个刷新通道来并行刷新，提高刷新处理的效率。
根据本实施例提供的显示页面的刷新方法，对于接收到的页面刷新请求，依据待显示页面包含的多个页面视图的视图布局信息分析出多个页面视图之间是否存在重叠区域，并针对存在重叠区域的页面视图的视图尺寸进行调整，以消除页面视图之间的重叠，后续则可针对调整后的页面视图划分的页面刷新区域，采用多个刷新通道进行并行刷新。由此可见，本实施例方案，通过对待显示页面中多个页面视图的视图尺寸进行调整，使多个页面视图之间不存在重叠区域，进而可利用多个刷新通道对多个页面刷新区域同时进行刷新，相较于现有技术中针对存在重叠区域的页面视图，只能利用全刷模式依次进行刷新的方式，可以极大地提高刷新显示的效率。
图2示出了本公开显示页面的刷新方法另一个实施例的流程图。该方法应用于墨水屏阅读器中。如图2所示，该方法包括以下步骤：
步骤S210：响应于接收到的页面刷新请求，获取待显示页面中包含的多个页面视图的视图布局信息。
其中，页面视图包括：电子书状态栏视图、电子书菜单栏视图、弹窗视图及电子书正文视图，其中，电子书正文视图包括但不限于阅读页面中正文内容所在的视图及书城页面中书城正文所在的视图。
其中，页面刷新请求为任意可以使屏幕显示内容发生改变的请求，例如，唤起菜单、弹窗或状态栏的刷新请求。
具体地，在接收到页面刷新请求后，获取待显示页面中包含的多个页面视图的视图布局信息，分析各个页面视图的位置关系，包括平面位置关系以及层叠位置关系，以便后续确定页面视图之间是否存在重叠。
进一步地，获取视图布局信息的方式如下：
方式一，在将墨水屏阅读器对应的阅读应用的adb(Android Debug Bridge，安卓调试桥)调试模式打开后，通过android studio的Layout Inspector的工具，可以获取到应用程序的视图布局信息。
方式二，确定与该页面刷新请求相对应的多个刷新申请，其中，多个刷新申请是由墨水屏阅读器的系统依据待显示页面中包含的页面视图的视图类型以及页面视图所在的位置区域划分出来的，通常情况下，将一类页面视图划分为一个刷新申请，将集中在连续位置区域的页面视图划分为一个刷新申请。获取各个刷新申请中包含的刷新区域信息，其中，在刷新申请中携带有刷新区域信息，该刷新区域信息由划分至该刷新申请的页面视图的视图区域的区域信息构成。根据各个刷新申请中包含的刷新区域信息，确定待显示页面中包含的多个页面视图的视图布局信息，在获取到各个刷新申请中携带的刷新区域信息之后，则可还原出待显示页面中包含的多个页面视图的视图布局信息，例如，将待显示页面中电子书菜单栏视图的刷新划分为一个刷新申请，以及将待显示页面中电子书状态栏视图的刷新划分为另一个刷新申请，则在获取到该两个刷新申请中携带的刷新区域信息后，确定电子书菜单栏视图与电子书状态栏视图的位置关系，即得到视图布局信息。
在一些实际的场景中，针对接收到的页面刷新请求，仅需对页面中少量的内容进行刷新，例如，在阅读书籍的过程中，点击墨水屏中央，会发起页面刷新请求，而此时通常只是在当前显示的内容的基础上，在墨水屏的顶部和顶部下方显示状态栏和菜单栏，其中状态栏主要用于显示电量、时间等信息，以及菜单栏主要用于显示调节字体、亮度等的设置信息。基于此，在本公开的一些可选的实施例中，将待显示页面与当前显示页面进行比较，根据比较结果确定该待显示区域中包含的页面变化区域，获取该页面变化区域中包含的各个页面视图的视图布局信息，通过这种方式，每次仅获取页面变化区域中包含的各个页面视图的视图布局信息，后续则可针对该发生变化的视图布局信息来进行分析与刷新，可提高刷新效率。
另外，页面刷新请求的种类多种多样，通常情况下，一个页面刷新请求对应着一帧画面的刷新，即一个图像帧的刷新，这种情况，通过获取该一个 图像帧所在的待显示页面的视图布局信息并进行分析即可；而在一些特殊情况下，页面刷新请求为用于多个图像帧的动态刷新请求，例如，菜单栏的呼出、消失过程会伴随动效，或者菜单栏中的按键在切换开关状态时也会有移动效果，这些动效的展示，往往是由多个图像帧连续刷新实现的。针对这种情况，在本公开的一些可选的实施例中，依次获取各个待显示页面，以根据获取到的待显示页面进行动态刷新，其中，此处的各个待显示页面是指构成动效的多个图像帧分别所在的页面；其中，每当获取到一个待显示页面后，比较本次获取到的待显示页面与上一次获取到的待显示页面是否相同；若相同，则表明前后两帧显示的内容未改变，则舍弃本次获取到的待显示页面，继续获取下一个待显示页面，即取消针对本次获取到的待显示页面进行视图布局信息的分析以及刷新的处理过程；若不相同，则表明前后两帧显示的内容发生了改变，则获取本次获取到的待显示页面中包含的多个页面视图的视图布局信息，以根据本次获取到的待显示页面进行动态刷新，进而将当前帧的图像刷新显示在墨水屏上。在这些动态刷新的可选实施例中，通过这种前后帧比较的方式，可以减少刷新次数，进而实现动态效果刷新速度的提升。
在上述动态刷新的可选实施例中，也可以结合针对局部变化区域进行分析的方式，在比较前后两帧显示的内容是否相同的基础上，进一步确定本次获取到的待显示页面相对于上一次获取到的待显示页面的动态变化区域，其中，可通过获取前后两帧图像，将两帧图像按区域分别进行比较，确定前后帧图像内容变化的区域(即动态变化区域)；或者，确定前后两帧图像中灰度发生变化的像素位置，记为变化像素，通过相邻变化像素构建灰度变化区域的外接矩形，将待显示页面中该外接矩形覆盖的区域确定为动态变化区域。通过上述方式，则可以缩小视图布局信息分析以及刷新的区域，进一步提高处理效率。然后，在获取视图布局信息时，仅获取该动态变化区域中包含的各个页面视图的视图布局信息。
步骤S220：当根据该视图布局信息确定该多个页面视图之间存在重叠区域时，针对存在重叠区域的页面视图的视图尺寸进行调整，以消除页面视图之间的重叠区域。
具体地，分析视图布局信息中各个页面视图的位置信息，确定任意两个页面视图的位置信息是否存在垂直于页面方向的重叠，例如，待显示页面的左上顶点为坐标原点，且菜单栏视图的横坐标的范围是[0，10]，纵坐标的范围是[1，5]，状态栏视图的横坐标的范围是[0，10]，纵坐标的范围是[0,2]，则菜单栏视图和状态栏视图在横坐标范围[0,10]，纵坐标范围[1,2]构成的区域内存在重叠。并且，在确定出存在重叠区域后，依据位置信息进一步确定出重叠区域的大小，以便后续据此消除重叠。
在本公开中，进行重叠区域的确定，是为了后续能够消除重叠并方便通过并行刷新通道并行处理多个刷新申请。相应地，在本公开的一些可选的实 施例中，在确定重叠区域的过程中，获取划分至不同的刷新申请的至少一个页面视图，并根据视图布局信息确定划分至不同的刷新申请中的页面视图是否存在重叠区域。通过针对划分至不同刷新申请的页面视图进行重叠区域的确定，以确保多个刷新申请的页面刷新区域之间不存在重叠，进而使得多个刷新申请可以通过并行刷新通道进行并行刷新处理，而无需关注同一刷新申请中的页面视图是否存在重叠，提高重叠区域确定的效率。例如，划分至刷新申请1的页面视图包括菜单栏视图a和菜单栏视图b，且分别的视图区域为视图区域A和视图区域B，划分至刷新申请2的页面视图为状态栏视图c，且视图区域为视图区域C，则只需对视图区域A或视图区域B是否与视图区域C之间具有重叠区域进行确定，最终只需确保视图区域A与视图区域C之间不存在重叠区域或视图区域B与视图区域C之间不存在重叠区域，则可进行并行处理。而视图区域A与视图区域B属于同一刷新申请内，并不影响并行刷新，则无需进行是否存在重叠的确定。
进一步地，在消除重叠区域时，针对任意两个存在重叠区域的页面视图，对其中至少一个页面视图的视图尺寸进行缩小处理，以使该任意两个页面视图之间的重叠区域消失。其中，将存在重叠区域的至少两个页面视图中的至少一个页面视图确定为目标视图，该目标视图为需要进行视图尺寸调整的视图。在一些可选的实施例中，针对该目标视图的冗余区域进行裁剪处理，其中，冗余区域是指不存在视图元素的区域，例如，菜单栏视图中，上边缘有一部分空白区域，该空白区域中不存在任何菜单控件或文字，则该空白区域为冗余区域，将该冗余区域进行裁剪，裁剪后的目标视图的视图尺寸变小，该至少两个页面视图之间的重叠区域减少甚至消除；其中，可依据重叠区域的大小进行裁剪，以使裁剪掉的区域与重叠区域恰好相等，避免对目标视图的视图形状造成过大的影响。在另一些可选的实施例中，针对该目标视图中包含的视图元素的排布方式进行调整，这些可选的实施例针对的是对目标视图的冗余区域进行裁剪处理不足以消除重叠区域的情况，通过调整目标视图的视图元素来增大冗余区域，以便通过裁剪冗余区域消除重叠区域。通过上述可选的实施方式，使得可以在消除重叠区域的同时，不影响目标视图中的视图元素的正常显示。
更进一步地，可通过设置页面视图的视图类型的优先级，并依据优先级从存在重叠区域的至少两个页面视图中确定出目标视图。其中，确定存在重叠区域的各个页面视图的视图类型，根据各个页面视图的视图类型，选择至少一个页面视图作为目标视图，按照视图类型的优先级由低至高选择目标视图。其中，页面视图的视图类型包括：系统类型以及应用类型，则在选择目标视图时，将应用类型的页面视图选择为目标视图，其中，应用类型的页面视图主要包括菜单栏视图、及弹窗视图，系统视图主要包括状态栏视图。在设置优先级时，设置系统类型的优先级高于应用类型的优先级，避免对系统类型的页面视图(例如状态栏视图)的视图尺寸的调整处理而影响所有页面 中该页面视图的显示。但是，若存在重叠区域的至少两个页面视图中不包括应用类型的页面视图时，则可选择系统类型的页面进行视图尺寸的调整，以消除重叠区域。通过上述确定目标视图的方式，可以优先确保系统类型的页面视图的视图尺寸不发生更改，以降低对系统设置的影响。
上述根据视图类型选择目标视图的方式仅为一种可选的方式，在实际实施时，还可以考虑尺寸调整的难度或者调整后对显示的影响度来选择相应的方式确定出目标视图，可选地，可根据存在重叠区域的至少两个页面视图中分别包括的视图元素的种类或数量来进行选择，例如，将至少两个页面视图按照包含的视图元素的种类的数量或包含的视图元素的数量由低至高进行排序，并选择排序靠前的预设数量的页面视图作为目标视图，例如，将包含的视图元素的数量最少的页面视图确定为目标视图，又如，将包含的视图元素单一(全为控件或全为文字的情况)的页面视图确定为目标视图，则可以降低调整的难度；或者，可根据存在重叠区域的至少两个页面视图的冗余区域的大小来进行选择，从该至少两个页面视图中选择出冗余区域最大的预设数量的页面视图确定为目标视图，以尽可能仅通过对冗余区域的裁剪处理来消除重叠区域，而避免对视图元素的调整。
需要说明的是，在仅针对划分至不同刷新申请的页面视图进行重叠区域的确定的实施例中，重叠区域的消除也是指消除不同刷新申请中包含的页面视图之间的重叠区域，则在确定目标视图时，是将任意两个刷新申请之间存在重叠区域的至少两个页面视图中的至少一个页面视图选择为目标视图。
图3a示出了一个具体示例中视图尺寸调整前的示意图。如图3a所示，菜单栏视图的高度为d2，状态栏视图的高度为d1，其中，高度d0对应的灰色区域为状态栏视图和菜单栏视图的重叠区域，假设按照视图类型的优先级对重叠区域进行调整，则需调整菜单栏视图的视图尺寸。图3b示出了对应图3a的示例进行视图尺寸调整后的示意图。如图3b所示，菜单栏视图经视图尺寸调整后的高度由d2变为d2-d0，此时菜单栏视图和状态栏视图不存在重叠区域。
步骤S230：针对待显示页面中包含的多个调整后的页面视图，确定与多个调整后的页面视图相对应的至少一个页面刷新区域；从该至少一个页面刷新区域中确定目标刷新申请的目标页面刷新区域，得到目标刷新申请更新后的刷新区域信息；其中，目标刷新申请是刷新模式为非全刷模式的申请。
实际中，针对一个页面刷新请求，系统会划分出一个或多个刷新申请，其中，刷新申请与页面刷新区域一一对应，每个刷新申请中携带有一个页面刷新区域的刷新区域信息，该页面刷新区域由划分至该刷新申请的页面视图的视图区域合并而成。
以及，在划分出的一个或多个刷新申请中，系统还会根据实际的刷新需求在刷新申请中携带刷新模式的模式信息，尤其针对一些需要确保不能出现 残影的页面视图的刷新，通常会默认采用全刷模式，相应地，则在刷新申请中携带全刷模式的模式信息，这些指定刷新模式为全刷模式的刷新申请，不能采用并行刷新的方式进行刷新处理。基于此，在本实施例中，通过筛选出刷新模式为非全刷模式的目标刷新申请，并针对这些目标刷新申请进行并行刷新处理。
具体地，针对任一刷新申请，检测刷新申请的刷新模式是否为全刷模式；根据检测结果从多个刷新申请中筛选出刷新模式不是全刷模式的目标刷新申请，至此则确定出了可以采用并行刷新方式进行刷新处理的目标刷新申请。
并且，在对页面视图的视图尺寸进行调整后，可得到经调整处理后各个页面视图的视图区域的区域信息以及其包含的视图元素的元素信息(包括元素的内容信息以及位置信息)。根据划分至目标刷新申请的调整后的页面视图，从至少一个页面刷新区域中确定目标刷新申请的目标页面刷新区域，得到目标刷新申请更新后的刷新区域信息。其中，根据各个页面视图被划分至的刷新申请，可以确定由划分至同一刷新申请的调整后的页面视图的视图区域构成的一个页面刷新区域，而由划分至目标刷新申请的调整后的页面视图的视图区域则构成了目标刷新申请的目标页面刷新区域。需要在此说明的是，调整前后各个页面视图划分至的刷新申请是不会改变的，只是页面视图的视图区域的区域信息或页面视图中包含的视图元素的元素位置发生了改变；以及，相较于系统初次划分时确定的页面刷新区域而言，该依据调整后的页面视图的视图区域确定的页面刷新区域为新的页面刷新区域，该新的页面刷新区域的刷新区域信息记为更新后的刷新区域信息，目标刷新申请也同理。
步骤S240：将携带该更新后的刷新区域信息的目标刷新申请分发至多个刷新通道并行刷新目标页面刷新区域。
具体地，将目标刷新申请分发至多个刷新通道，则可以完成目标页面刷新区域的并行刷新处理。其中，目标刷新申请中携带更新后的刷新区域信息，以及携带视图元素的元素信息，其中，元素信息包括元素内容信息以及元素位置信息，该视图元素是指划分至目标刷新申请的调整后的页面视图包含的视图元素，相应地，元素位置则与调整后的视图元素的位置信息一致。任一刷新通道在接收目标刷新申请后，可根据目标刷新申请中携带的更新后的刷新区域信息和元素信息，将划分至当前的目标刷新申请的页面视图的视图元素刷新显示在目标页面刷新区域的相应位置中。
进一步地，在将目标刷新申请分发至刷新通道之前，根据该目标刷新申请的数量向刷新芯片申请并行刷新时刷新通道的通道数量，通常情况下，刷新芯片上并行刷新通道的数量是固定的，例如，为16个。通过向刷新芯片进行申请，可便于刷新芯片对有限的并行刷新通道进行调度，其中，当目标 刷新申请的数量少于刷新芯片上的并行刷新通道的总数量时，则可分配与目标刷新申请数量相同的并行刷新通道以响应当前的页面刷新请求。根据刷新芯片分配的通道数量将目标刷新申请分发至与该通道数量一致的刷新通道，其中，若分配的通道数量少于目标刷新申请的数量，则需将多个目标刷新申请分批次分发至与该通道数量一致的刷新通道；若分配的通道数量多于或等于目标刷新申请的数量，则可将目标刷新通道一次分发至于与通道数量一致的刷新通道。
本实施例方案可广泛应用于墨水屏中需要快速刷新显示的场景，例如，针对唤起菜单、弹窗或状态栏的页面刷新请求，通过对重叠区域进行消除处理，则目标刷新申请的目标页面刷新区域之间不存在重叠，可同时并行刷新，相较于现有技术中因重叠而只能一个接一个依次刷新的方式，可以极大地提高刷新显示的效率；并且，并行刷新时直接将墨水粒子从当前帧的灰度位置驱动到下一帧图像的灰度位置，中间省去了闪黑闪白的过程，进一步提高了刷新速度。
根据本实施例提供的显示页面的刷新方法，对于接收到的页面刷新请求，依据待显示页面包含的多个页面视图的视图布局信息分析出多个页面视图之间是否存在重叠区域，并针对存在重叠区域的页面视图的视图尺寸进行调整，以消除页面视图之间的重叠，其中，可仅针对前后帧发生变化的页面区域的视图布局信息进行分析和调整，通过减少分析数据量来提高重叠区域的分析及消除的速度；以及，在进行重叠区域的分析时，可以仅分析被划分至不同刷新申请页面视图的视图区域之间是否存在重叠，然后针对刷新申请之间的重叠进行消除，进而在确保刷新申请可通过并行刷新通道进行刷新处理的同时，进一步提高重叠区域的分析和消除的效率；并且，在采用并行刷新通道对页面刷新区域进行并行刷新之前，对刷新申请的刷新模式进行检测，并根据检测结果将刷新模式不是全刷模式的刷新申请分发至并行刷新通道进行并行刷新处理，以在确保刷新速率的同时，避免特定视图的刷新信息留下残影，提升刷新显示效果。由此可见，本实施例方案，通过对待显示页面中多个页面视图的视图尺寸进行调整，使多个页面视图之间不存在重叠区域，进而可利用并行刷新通道对多个页面刷新区域同时进行刷新，相较于现有技术中针对存在重叠区域的页面视图，只能依次进行刷新的方式，可以极大地提高刷新显示的效率；同时，通过前后帧比较确定出发生变化的页面区域或对刷新申请之间的重叠区域进行分析，可以提高重叠区域的分析以及消除的效率。
本公开实施例提供了一种非易失性计算机可读存储介质，该非易失性计算机可读存储介质存储有至少一可执行指令，该计算机可执行指令可执行上述任意方法实施例中的显示页面的刷新方法。
可执行指令具体可以用于使得处理器执行以下操作：
响应于接收到的页面刷新请求，获取待显示页面中包含的多个页面视图的视图布局信息；
当根据视图布局信息确定多个页面视图之间存在重叠区域时，针对存在重叠区域的页面视图的视图尺寸进行调整，以消除页面视图之间的重叠区域；
针对待显示页面中包含的多个调整后的页面视图，确定与多个调整后的页面视图相对应的至少一个页面刷新区域，通过多个刷新通道并行刷新各个页面刷新区域。
在一种可选的方式中，可执行指令使处理器执行以下操作：
