显示设备可以以图片形式展示图片类型的文件。以图片形式展示图片类型文件的实现方式一般有两种：一种是将原图缩小后显示，该方法会占用大量的内存资源；另一种方式是分别将用户打开的文件夹中包含的图片生成一个缩略图，显示缩略图，但是生成缩略图会消耗一定的时间，影响显示效率，用户体验不好。
为了解决现有技术存在的问题，本申请实施例示出的一种显示设备，具体的可以参阅图5，图5为根据一可行性实施例示出的显示设备的结构框图，其中，显示设备至少包括显示器2和控制器1，其中，控制器内设置有存储器11和处理器12，存储器11用于存储显示设备下载的文件。用户可以根据需求将一些文件放置于同一个文件夹内。处理器，用于执行存储在存储器中的操作系统和应用程序指令或线程。以及根据接收的用户输入指令，来执行各种应用程序、数据和内容的处理，以便最终显示和播放各种音视频内容。具体应 用到本实施例示出的方案中，处理器可以调用缩略图构建线程121、文件管理线程122和系统框架中的展示层123。显示器与控制器的交互流程图可以参阅图6。
显示器执行步骤S101显示已下载的文件夹；其中，文件夹包括至少一个文件，每个文件夹配置一个缩略图列表，缩略图列表用于存储部分或全部文件的缩略图。
为了方便文件的查找，用户通常会配置多个文件夹，图7为根据一可行性实施例示出的显示器显示已下载的文件夹时展示界面示意图。从图中可以看出显示器可以同时展示多个文件夹。
用户可以根据需求将一些文件聚类在同一个文件夹中。例如，可以将人物相关的图片聚类在人物文件夹中，可以将山水相关的图片聚类在山水文件夹中。本申请实施例并不对文件的聚类方式作以限定，在实际应用的过程中，用户可以根据需求配置文件夹。
用户执行步骤S102选中文件夹；

例如，图7展示的实施例，展示界面上配置有焦点，焦点被配置受控移动，用户可以通过遥控器控制焦点移动，以完成文件夹的选中。
再例如，在一可行性实施例中，控制器可以安装有语音助手软件，用户可以通过语音指令来完成文件夹的选中。
在实际应用的过程中，用户选中文件夹的实现方式可以是但不限于上述两种方式。
响应于用户对文件夹的选中，控制器被配置为执行步骤S103依次遍历用户选中文件夹对应的缩略图列表；
本申请并不对控制器遍历缩略图列表的顺序作以限定；
例如，在一可行性实施例中，文件夹中的文件按照文件的名称降序排列，在此情况下控制器可以按照文件名称的排序依次遍历用户选中文件夹对应的缩略图列表，判断缩略图列表中是否记录与所述文件相匹配的缩略图。
举例说明，在一可行性实施例中，文件夹中共包含8个文件分分别为：文件1、文件2、文件3、文件4、文件5、文件6、文件7和文件8；在文件夹内8个文件按照文件的名称降序排列的结果可以参阅表1；

Figure PCTCN2021119627-appb-000002
控制器首先判断缩略图列表中是否记录与文件1相匹配的缩略图；而后，判断缩略图列表中是否记录与文件2相匹配的缩略图……判断缩略图列表中是否记录与文件8相匹配的缩略图。
再例如，在一可行性实施例中，文件夹中的文件按照文件的修改时间降序排列，在此情况下控制器可以按照修改时间的排序依次遍历用户选中文件夹对应的缩略图列表，判断缩略图列表中是否记录与所述文件相匹配的缩略图。
在实际应用的过程中，控制器遍历缩略图列表的顺序可以是但不限于上述两种方式，在此申请人不做过多的限定。

例如，在一可行性上实施例中可以为文件和该文件的缩略图配置相应的标识。控制器基于文件的标识在缩略图列表内查找与所述标识相匹配的缩略图；
举例说明，在一可行性实施例中，缩略图列表中记录有4个缩略图，分别为：缩略图1、缩略图2、缩略图3、缩略图4，具体的缩略图列表可以参阅表2；
表2
序号 文件名称 标识 备注
1 缩略图1 标识1  
2 缩略图2 标识2  
3 缩略图3 标识3  
4 缩略图4 标识4  
控制器基于文件1的标识(标识1)遍历表2，确定表2中记录有与文件1的缩略图；而后，控制器基于文件2的标识(标识2)遍历表2，确定表2中记录有与文件2的缩略图……控制器基于文件5的标识(标识5)遍历表2，确定表2中未记录有与文件2的缩略图。
再例如，为了减少缩略图列表存储的数据量，在一可行性实施例中，可以将文件名称作为标识，具体的缩略图列表可以参阅表3；

2 文件2.png  
3 文件3.png  
4 文件4.png  
再例如，在一些可行性实施例中，缩略图列表和文件可能存储在同一文件夹中，在此情况下不允许缩略图与文件采用同一个名称，基于此本申请实施例示出一种缩略图的命名方式，具体的名称方式为缩略图的名称＝文件的存储地址+文件的名称，具体的缩略图列表可以参阅表4；
序号 文件名称 备注
1 照片_人物_文件1.png.bmp  
2 照片_人物_文件2.png.bmp  
3 照片_人物_文件3.png.bmp  
4 照片_人物_文件4.png.bmp  
采用上述命名方式所带来的有益效果在后文的方案中会详细描述。
在实际应用的过程中，判断缩略图列表内是否记录该文件的缩略图的实现方式可以是但不限于上述几种方式，在此申请人不做过多的限定。
如果缩略图列表内记录该文件的缩略图，控制器执行步骤S13控制显示器在文件展示位置展示缩略图，控制器继续执行步骤S11。
其中，文件展示位置由用户设定的图标尺寸及显示器展示界面的尺寸所决定。图9为根据一可行性实施例示出的显示器展示界面的示意图。图9示出的实施例中，用户设定图标以超大图标的形式展示，此时，显示器的展示界面上可以同时展示8个图标，将展示界面划分为4*2个区域，其中每个区域为一个文件的展示位置。图9中的区域A为文件1的展示区域。
如果缩略图列表内未记录该文件的缩略图，控制器执行步骤S14控制显示器在文件展示位置展示预置图标，控制器继续执行步骤S11。
本申请实施例示出的方案并不对预置图标的样式作以限定。
图9中的文件夹4、5、7、8示出的图标，仅是示例性的展示一种预置图标的样式，在实际应用的过程中预置图标的样式可以是但不限于图9中展示的样式。
如果缩略图列表记录文件的缩略图，控制器被配置为执行步骤S104控制显示器在文件展示位置展示缩略图；
如果缩略图列表未记录文件的缩略图，控制器被配置为执行步骤S105控制显示器在文件展示位置展示预置图标；
下面结合具体的实例对本实施例示出的显示设备的作业过程作以详细的说明。
在一可行性实施例中，用户选中文件夹1，其中文件夹1包含8个文件，分别为文件1、文件2、文件3、文件4、文件5、文件6、文件7和文件8；文件夹1对应的缩略图列表为缩略图列表1。响应于用户对文件夹1的选中，控制器基于文件1的名称遍历缩略图列表1，确定缩略图列表1记录有文件1的缩略图，控制器控制显示器展示文件1的缩略图，此时显示器的展示界面可以参阅图10中的界面11；而后，控制器基于文件2的名称遍历缩略图列表1，确定缩略图列表1记录有文件2的缩略图，控制器控制显示器展示文件2的缩略图，此时显示器的展示界面可以参阅图10中的界面12；而后，控制器基于文件3的名称遍历缩略图列表1，确定缩略图列表1未记录文件3的缩略图，控制器控制显示器展示预置图标，此时显示器的展示界面可以参阅图10中的界面13……控制器基于文件8的名称遍历缩略图列表1，确定缩略图列表1未记录文件8的缩略图，控制器控制显示器展示预置图标，此时显示器的展示界面可以参阅图10中的界面14。
至此完成本实施例的描述。
本实施提供的技术方案设计的初衷是当待展示文件为媒资文件时，可以以缩略图的形式展示该文件，以对用户起到提示的作用。如果文件的类型为非媒资类型，控制器继续遍历缩略图列表无疑是浪费控制器的计算资源，基于此本申请实施例示出的方案中控制器可以预先判断文件类型是否为媒资类型，然后根据判断结果确定是否遍历缩略图列表，以此降低控制器的数据处理量。
本申请实施例示出一种显示设备，显示设备的结构框图可以参阅图5，其中，显示设备中显示器与控制器的交互流程图可以参阅图11。
显示器执行步骤S201显示已下载的文件夹；
已下载文件夹的显示方式可以参阅上述实施例，在此便不赘述。
用户执行步骤S202选中文件夹；
用户选中文件夹的实现方式可以参阅上述实施例，在此便不赘述。
响应于用户对文件夹的选中，控制器被配置为执行步骤S203依次读取文件夹内储存文件的文件类型；
读取文件的文件类型的实现方式有多种；
例如，在一可行性实施例中，可以通过文件名称的后缀来读取文件类型。举例说明，文件的文件名称为“20201126-1.JPG”，可以确定该文件类型为图片；文件的文件名称为“20201126-2.PNG”，可以确定该文件类型为图片；文件的文件名称为“20201126-3.AVI”，可以确定该文件类型为视频；文件的文件名称为“20201126-4.MOV”，可以确定该文件类型为视频。
如果文件类型不是媒资类型，控制执行步骤S204控制显示器在文件展示位置展示显示预置图标；
本申请实施例示出的媒资类型包括图片和视频。
其中预置图标的展示方式可以参阅上述实施例，在此便不赘述。
在一些可行性实施例中，为了提升用户的体验感，本申请实施例预先设计每种文件类型对应的文件类型图标，用户通过显示器展示的文件类型图标便可获知该文件的类型，进而提升用户的体验感。
图12为根据一可行性实施例示出的显示器展示界面的示意图。从图中可以看出，其中文件1、文件2、文件3、文件6以缩略图的形式进行展示。文件4、文件5、文件7、文件8以文件类型图标的形式进行展示。用户通过图12的展示内容可以看出文件4为音频类型的文件，文件5为音频类型的文件，文件7为音频类型的文件，文件8为安装包类型的文件。
可见本申请实施例示出的技术方案，当控制器确定文件类型不是媒资类型时，控制显示器在文件展示位置展示显示文件类型图标，用户可以通过显示器展示的文件类型图标，获知该文件的类型，进而提升用户的体验感。
如果文件类型为媒资类型，控制执行步骤S205遍历文件夹的缩略图列表；
遍历文件夹的缩略图列表的实现方式可以参阅上述实施例，在此便不赘述。
如果缩略图列表记录文件的缩略图，控制器被配置为执行步骤S206控制显示器在文件展示位置展示缩略图；
如果缩略图列表未记录文件的缩略图，控制器被配置为执行步骤S207控制显示器在 文件展示位置展示媒资图标；
本实施例中媒资图标为图片图标或视频图标。
在一可行性实施例中，所述媒资图标不同于文件类型图标。由于在后续过程中本申请实施例示出的技术方案会对那些不存在缩略图的媒资文件构建缩略图，但是对那些非媒资文件不做任何处理。因此本申请实施例示出的方案将所述媒资图标设计成不同于文件类型图标，可以对用户起到一定的提示作用，提示用户在后续过程中哪些文件可能出现缩略图。
本实施例中涉及到的媒资可以包括图片和/或视频，图13A为根据一可行性实施例示出的文件展示过程的流程图；
控制器执行步骤S21读取文件类型；
控制器执行步骤S22判断文件类型是否是图片；
如果文件类型是图片，控制器执行步骤S231判断缩略图列表中是否记录该文件的缩略图；
如果缩略图列表内记录该文件的缩略图，控制器执行步骤S241控制显示器在文件展示位置展示缩略图，控制器继续执行步骤S21；

如果缩略图列表内记录该文件的缩略图，控制器执行步骤S362控制显示器在文件展 示位置展示缩略图，控制器继续执行步骤S31；
下面结合具体的实例对本实施例示出的显示设备的作业过程作以详细的说明。
在一可行性实施例中，用户选中文件夹2，其中文件夹2包含8个文件，分别为文件1、文件2、文件3、文件4、文件5、文件6、文件7和文件8；文件夹2对应的缩略图列表为缩略图列表2。响应于用户对文件夹2的选中，控制器读取文件1名称的后缀，通过文件1名称的后缀判断文件1为图片；控制器基于文件1的名称遍历缩略图列表2，确定缩略图列表2记录有文件1的缩略图，控制器控制显示器展示文件1的缩略图，此时显示器的展示界面可以参阅图14中的界面21。而后，控制器读取文件2名称的后缀，通过文件2名称的后缀判断文件2为音频类型文件，控制器控制显示器展示音频类型文件图标，此时显示器的展示界面可以参阅图14中的界面22。而后，控制器读取文件3名称的后缀，通过文件3名称的后缀判断文件3为图片；控制器基于文件3的名称遍历缩略图列表2，确定缩略图列表2未记录有文件3的缩略图，控制器控制显示器图片图标，此时显示器的展示界面可以参阅图14中的界面23……控制器读取文件8名称的后缀，通过文件8名称的后缀判断文件8不是图片，控制器继续通过文件8名称的后缀判断文件8为视频；控制器基于文件1的名称遍历缩略图列表2，确定缩略图列表2记录有文件8的缩略图，控制器控制显示器展示文件8的缩略图，此时显示器的展示界面可以参阅图14中的界面24。
至此完成本实施例的描述。
本实施提供的技术方案设计的初衷是当待展示文件为媒资文件时，可以以缩略图的形式展示该文件，以对用户起到提示的作用。为了进一步的提升用户的体验感，本实施例示出的技术方案中，在控制器内设置有缩略图生成线程，缩略图线程用于当缩略图列表内不存在当前文件的缩略图示，构建当前文件的缩略图，以保证媒资类型的文件均可以以缩略图的形式进行展示，进而提升用户的体验感。
本申请实施例示出一种显示设备，显示设备的结构框图可以参阅图5，其中，显示设备中显示器与控制器的交互流程图可以参阅图15。
响应于用户对文件夹的选中，文件管理线程被配置为执行步骤S301依次读取文件夹内储存文件的文件类型；
本申请实施例示出的技术方案中文件管理线程通过文件的名称确定文件类型。其中，读取文件类型的实现方式可以参阅上述实施例，在此便不赘述。
如果文件类型为媒资类型，文件管理线程被配置为执行步骤S302遍历文件夹的缩略图列表；
遍历缩略图列表的实现方式可以参阅上述实施例在此便不赘述。
如果缩略图列表未记录文件的缩略图，文件管理线程被配置为执行步骤S3031调用缩略图生成线程；
本申请实施例示出的技术方中，文件管理线程调用略图生成线程的同时，将文件的名称以及文件的存储地址一通发送给缩略图生成线程。
缩略图生成线程被配置为执行步骤S3041构建文件的缩略图；
缩略图生成线程可以基于文件的储存位置找到文件所在的文件夹，然后基于文件的名称找到待构建缩略图的文件。
构建缩略图的实现方式可以采用本领域惯用的缩略图构建方式，例如通过以下步骤构建缩略图。(1)将源图像(文件)装载到一个PHP(Hypertext Preprocessor，超文本预处 理器)变量中。(2)确定源图像的高度和宽度。(3)创建一个具有正确尺寸的空白缩略图。(4)复制原有图像到空白缩略图。(5)使用正确的内容类型显示缩略图。
本实施例仅是示例性的介绍一种缩略图的构建方法，在实际应用的过程中缩略图的构建方式可以是，但不限于上述方式。
本实施例中缩略图的名称＝存储地址+文件名称，所述存储地址为缩略图对应文件的存储地址。文件名称为缩略图对应文件的名称。通过文件名称可以构建文件与缩略图之间的对应关系。在遍历缩略图列表的过程中也是基于文件名称实现的。
响应于完成缩略图的构建，缩略图生成线程被配置为执行步骤S3051发送更新消息至展示层；
本实施例中，更新消息中封装有缩略图的存储地址，以及缩略图的名称。
展示层执行步骤S3061基于更新消息携带的缩略图存储地址存储的数据绘制缩略图，显示器展示的内容由媒资图标转换为缩略图。
展示层基于更新消息携带的缩略图存储地址存储的数据绘制缩略图，绘制缩略图数据的实现方式可以采用本领域惯用的图像绘制方式。
展示层执行步骤S3071控制显示器展示缩略图；
展示层基于更新消息携带的缩略图名称找到文件的媒资图片，然后控制显示器撤销媒资图标展示构建的缩略图。
如果缩略图列表未记录文件的缩略图，文件管理线程S3032发送预置图标地址至展示层；
本申请实施例示出的方案中，预置图标可以为多个文件夹所共用，因此，展示图片可以存储在一个独立的存储区域内，进而保证当一个文件夹被删除时，预置图标依然可以为其他文件夹提供服务。
相比较之下，预置图标列表为一个文件夹服务。当该文件夹被删除时，该文件夹对应的缩略图列表也就失去了意义。因此，可以将缩略图列表存储在其对应的文件夹内，具体的，生成缩略图放到本磁盘根目录下.vrThumbnail文件夹下，即在/storage/sdcard这个磁盘内创建.vrThumbnail文件夹，在此情况下，文件夹被删除，相应的，其对应的缩略图列表一同被删除。

当待浏览数据写入数据列表的时间等于预置时间时，主线程将数据列表记录的待浏览数据写入临时列表。举例说明，在一可行性实施例中，待浏览数据共包括1024个文件，主线程以数据流的形式将待浏览数据写入数据列表；当待浏览数据写入数据列表的时间等于预置时间时，主线程将524个文件写入数据列表，此时主线程将写入数据列表中的524个文件写入临时列表，同时主线程继续将剩余的(1054-524)个文件写入数据列表。
如果将全部的待浏览数据写入数据列表的时间小于或等于预置时间，主线程不将数据列表记录的待浏览数据写入临时列表；举例说明，在一可行性实施例中，待浏览数据共包括512个文件，主线程以数据流的形式将待浏览数据写入数据列表；在300ms时(300ms小于预置时间500ms)主线程将全部的将待浏览数据写入数据列表，在此情况下，主线程无需将数据列表内记录的待浏览数据写入临时列表内。在后续的过程中主线程直接调用数据列表中记录的512个文件。
主线程被配置为执行步骤S195如果临时列表记录有待浏览数据，则基于临时列表记录的待浏览数据绘制展示页面；如果临时列表未记录待浏览数据，则基于数据列表记录的待浏览数据绘制展示页面。

用户执行步骤S211触发文件浏览请求；

主线程被配置为执行步骤S2121响应于接收到文件浏览请求，启动子线程，以使得子线程将待浏览数据写入数据列表；S2122启动定时器，定时器用于记录待浏览数据写入数据列表的时间；
将待浏览数据写入数据列表的实现方式可以参阅上述实施例，在此便不赘述。
如果将全部的待浏览数据写入数据列表的时间大于预置时间，则当待浏览数据写入数据列表的时间等于预置时间时，子线程被配置为执行步骤S2131将数据列表记录的待浏览数据写入临时列表；
如果将全部的待浏览数据写入数据列表的时间小于或等于预置时间，子线程被配置为执行步骤S2132则不将数据列表记录的待浏览数据写入临时列表；
子线程被配置为执行步骤S214对记录在待浏览数据/或数据列表内的待浏览数据进行排序；
本申请实施例并不对记录在待浏览数据/或数据列表内的待浏览数据的排序规则作以限定，在实际应用的过程中用户可以在文件浏览请求中限定排序规则。
例如，在一可行性实施例中，用户在文件浏览请求中限定文件按照文件命名降序排序，相应的，子线程按照文件命名降序的排序规则对记录在待浏览数据/或数据列表内的待浏览数据进行排序。
再例如，在一可行性实施例中，用户在文件浏览请求中限定文件按照文件生成的时间降序排序，相应的，子线程按照文件生成的时间降序的排序规则对记录在待浏览数据/或数据列表内的待浏览数据进行排序。
本申请实施例仅是示例性的介绍几种文件排序规则，在实际应用的过程中文件的排序 规则可以是，但不限于上述几种方式。
主线程被配置为执行步骤S215如果临时列表记录有待浏览数据，则基于临时列表记录的待浏览数据绘制展示页面；如果临时列表未记录待浏览数据，则基于数据列表记录的待浏览数据绘制展示页面。
主线程被配置为执行步骤S216控制显示器显示展示页面。
至此完成本实施例的描述。
本申请实施例示出的技术方案设计的初衷是当进行文件浏览时，将全部待浏览文件以分页的形式进行展示，以保证在待浏览数据量较大时，无需等待将全部的待浏览数据写入数据列表后，才进行展示页面的渲染，进而降低用户的等待时间。为了保证展示页面的灵活绘制，本申请实施例示出一种展示页面的绘制方式，具体的可以参阅图22，图22为根据一可行性实施例示出的展示页面的绘制流程图，其中主线程/子线程被配置为执行步骤S221：基于初始位置及文件数量，在排序后的待浏览数据中筛选出分页数据；
本申请实施例示出的技术方案中，文件浏览请求携带有文件请求数据参数，文件请求数据参数可以包括：startIndex和length：startIndex为获取文件的起始位置和length为文件数量，即一页显示的文件数据。
举例说明，在一可行性实施例中，初始位置为1，文件数量为10；500ms时子线程完成对临时数据表内记录的数据的排序，临时数据表可以参阅表1：
表1
序号 待浏览数据 备注
1 待浏览数据17 -
2 待浏览数据25 -
3 待浏览数据34 -
4 待浏览数据28 -
5 待浏览数据26 -
6 待浏览数据9 -
7 待浏览数据7 -
8 待浏览数据13 -
9 待浏览数据29 -
10 待浏览数据8 -
…… …… ……
N 待浏览数据86 -
在本是实施例中待浏览数据17、待浏览数据25、待浏览数据34、待浏览数据28、待浏览数据26、待浏览数据9、待浏览数据7、待浏览数据13、待浏览数据29及待浏览数据8为分页数据。
主线程执行步骤S222基于分页数据绘制展示页面。
采用表1示出的实施例绘制出的展示页面可以参阅图23，图23为根据一可行性实施例示出的展示页面的示意图。
在一些可行性实施例中文件请求数据参数还可以包括：orderBy，orderBy为排序规则。在文件请求数据参数不包括orderBy的情况下，默认根据文件名称排序。
在一些可行性实施例中文件请求数据参数还可以包括：fileType，fileType为指定获取 文件类型。在文件请求数据参数包括fileType的应用场景下，主线程/子线程将与fileType具有相同文件类型的待浏览数据写入数据列表。
在一些可行性实施例中文件请求数据参数还可以包括：获取目录，path为获取目录。在文件请求数据参数包括path的应用场景下，主线程/子线程将path目录下的全部待浏览数据写入数据列表。
采用本实施例示出的显示设备，用户可以根据需求输入相应的文件请求数据参数，以达到展示页面的灵活绘制的目的。
在一可行性实施例中，为了进一步缩短用户的等待时间，预置时间写入数据列表的数据量等于绘制一页展示页面所需的数据量。
举例说明，在一可行性实施例中，初始位置为M，文件数量为N；主线程将N个待浏览数据写入数据列表所需的时间为Lms，那么在本实施例示出的方案中预置时间可以为Lms。
在一可行性实施例中，主线程/子线程还被配置为：响应于将全部的待浏览数据写入数据列表，对数据列表记录的待浏览数据进行排序；响应于完成数据列表内待浏览数据的排序，如果待浏览数据写入数据列表的时间小于或等于预置时间，则关闭定时器；如果待浏览数据写入数据列表的时间大于预置时间，则删除临时列表内记录的待浏览数据。
在实际应用的过程中，存在两种情况需要对显示器展示的浏览页面进行刷新，一种情况是用户重新输入文件浏览请求，在此情况下，主线程/子线程需要读取件浏览请求内path，然后基于path将该path目录下的全部待浏览数据写入数据列表。一种情况是用户重新输入页面更新请求，用户输入页面更新请求的目的在于对显示器当前展示的展示页面进行翻页处理。举例说明，在一可行性实施例中，文件浏览请求中初始位置为1，文件数量为10，在此情况下显示器首次展示的展示页面为排序为1-10的待浏览数据；而后用户触发页面更新请求的目的在于控制显示器展示排序为11-20的待浏览数据，在此情况下，主线程/子线程无需重新获取待浏览数据，可以直接调用记录在临时列表或数据列表内的待浏览数据。具体的实现过程可以是：主线程/子线程还被配置为：响应于接收到页面更新请求，如果临时列表内未记录待浏览数据，则基于记录在数据列表内的待浏览数据绘制展示页面；如果临时列表内记录的待浏览数据，将数据列表记录的数据写入临时列表；对临时列表记录的待浏览数据进行排序；基于记录在临时列表内记录的待浏览数据绘制展示页面。
在一可行性实施例中，用户可能不进行后续的页面刷新操作，为了在一定程度上降低主线程/子线程的数据处理量，在一可行性实例中如果待浏览数据写入数据列表的时间大于预置时间，响应于将全部的待浏览数据写入数据列表，主线程/子线程的数据处理量可以不对记录的待浏览数据进行排序。具体的实现过程可以是，主线程/子线程还被配置为：响应于将全部的待浏览数据写入数据列表，如果待浏览数据写入数据列表的时间小于或等于预置时间，则关闭定时器；如果待浏览数据写入数据列表的时间大于预置时间，则删除临时列表内记录的待浏览数据。相对应的，响应于接收到页面更新请求，控制器还被配置为：如果临时列表内未记录待浏览数据，则对数据列表记录的待浏览数据进行排序；响应于完成数据列表内待浏览数据的排序，基于记录在数据列表内的待浏览数据绘制展示页面；如果临时列表内记录的待浏览数据，将数据列表记录的数据写入临时列表；对临时列表记录的待浏览数据进行排序；基于记录在临时列表内记录的待浏览数据绘制展示页面。

值得注意的是，由于每个数据流中包含的字节数决定后续拷贝进度的刷新率，每个数据流中包含的字节数越少后续拷贝进度的刷新率越快，用户体验感越好；同时每个数据流中包含的字节数也决定文件的拷贝速率，每个数据流中包含的字节数越多在一定程度上文件的拷贝速率越快。因此，设计者在设计由于每个数据流中包含的字节数是应兼顾续拷贝进度的刷新率及文件拷贝的效率。在一可行性实施例中，数据流中包含的字节数可以是1024字节，每个数据流中包含1024个字节可以兼顾续拷贝进度的刷新率及文件拷贝的效率。
每次响应于完成一个数据流的写入，主线程被配置为执行步骤S254计算当前文件写入量；
计算当前文件写入量的实现方式有多种；
例如，在一可行性实施例中，主线程可以根据如下公式，计算当前文件写入量：
copyTotle(N)＝copyTotle(N-1)+size(N)；
其中，copyTotle(N)为当前文件写入量，copyTotle(N-1)在最近一次数据流写入之前，写入目标存储区的数据量；size(N)为最近一次写入的数据流包含的字节数。
举例说明，当完成第一个数据流写入时，copyTotle(1-1)＝0字节，size(1)＝1024字节，相应的copyTotle(1)＝0+1024；完成第二个数据流写入时size(2)＝1024字节，copyTotle(2)＝1024+1024；依次进行，完成第N个数据流写入时size(N)＝256字节，copyTotle(N)＝1024+1024+……+256；
采用本申请实施例示出的当前文件写入量的计算方式，每次写入目标存储区内的数据流包含的字节数可以相同也可以不同，该实现方式的适用范围更宽。
再例如，在一可行性实施例中，主线程可以根据如下公式，计算当前文件写入量：
copyTotle(N)＝N*size(N)；
其中，copyTotle(N)为当前文件写入量，size(N)为一次写入的数据流包含的字节数，N为写入数据流的次数。
举例说明，当完成第一个数据流写入时，size(1)＝1024字节，相应的copyTotle(1)＝1024*1；完成第二个数据流写入时，size(2)＝1024字节，copyTotle(2)＝1024*2；依次进行，完成第N个数据流写入时，size(N)＝1024字节，copyTotle(N)＝1024*N；
本实施例仅是示例性的介绍两种当前文件写入量的计算方式，在实际应用的过程中，当前文件写入量的计算法方式可以是但不限于上述两种方式。
主线程被配置为执行步骤S255基于当前文件写入量和文件总量计算文件拷贝进度，文件总量为待拷贝文件包含的字节数；
本申请文件拷贝进度可以采用百分比的形式展示，具体的：
文件拷贝进度＝当前文件写入量/文件总量；
举例说明，在一可行性实施例中，文件总量为10*1024个字节。当完成第一个数据流写入时，copyTotle(1)＝1024，此时的文件拷贝进度为1024/(10*1024)；当完成第二个数据流写入时，copyTotle(2)＝1024*2，此时的文件拷贝进度为(1024*2)/(10*1024)；当完成第三个数据流写入时，copyTotle(3)＝1024*3，此时的文件拷贝进度为(1024*3)/(10*1024)……当完成第10个数据流写入时，copyTotle(10)＝1024*10，此时的文件拷贝进度为(1024*10)/(10*1024)。
主线程执行步骤S256基于文件拷贝进度绘制拷贝窗口；
主线程执行步骤S257控制显示器展示拷贝窗口。
图26为根据一可行性实施例示出的展示有拷贝窗口的显示器的示意图，从图中可以看出拷贝窗口26可以以浮层窗口的形式存在。在拷贝窗口内，为了使用户以更加直观的方式了解拷贝进度，在拷贝窗口内可以设置有进度条261。进一步的，为了使用户更加准确的获知拷贝进度，可以以数字的形式展示拷贝进度262；为了进一步提升用户的体验感可以设置一些提示语263。本实施例中并不对提示语的内容作以限定，可以根据需求配置提示语的内容。
下面结合具体的实例对本申请实施例示出的显示设备的工作过程作以说明；
在一可行性实施例中，待拷贝文件的文件总量为10*1024个字节。响应于用户触发文件拷贝功能，主线程待拷贝文件写入内存缓冲区；而后，主线程以数据流的形式将内存缓冲区内存储的待拷贝文件写入目标存储区，本申请中每个数据流包含1024个字节；第一个数据流写入目标存储区时，主线程得到的当前文件写入量＝1024个字节；主线程得到拷贝进度＝1024/1024*10＝1/10；主线程基于拷贝进度绘制拷贝窗口，此时显示器的展示界面可以参阅图27的界面11；第二个数据流写入目标存储区时，主线程得到的当前文件写入量＝1024个字节；主线程得到拷贝进度＝1024*2/1024*10＝1/10；主线程基于拷贝进度绘制拷贝窗口，此时显示器的展示界面可以参阅图27的界面12……第二个数据流写入目标存储区时，主线程得到的当前文件写入量＝1024个字节；主线程得到拷贝进度＝1024*10/1024*10＝100％；主线程基于拷贝进度绘制拷贝窗口，此时显示器的展示界面可以参阅图27的界面13。
本申请实施例示出的显示设备包：控制器，被配置执行主线程；响应于用户触发文件拷贝功能，主线程可以以数据流的形式将所述内存缓冲区内存储的待拷贝文件写入目标存储区；每次响应于完成一个所述数据流的写入，计算当前文件写入量，基于所述当前文件写入量和文件总量计算文件拷贝进度。可见本申请实时示出的显示设备中的主线程每次将数据流写入目标存储区时，均基于当前文件写入量计算拷贝进度，所述拷贝进度是基于实际的拷贝情况计算得出，因此计算结果较为准确。主线程均可将拷贝进度呈现给用户，以保证用户可以准确的获知文件的拷贝进度，用户体验感较好。
至此完成本实施例的描述。
通常显示设备的系统内设置一个主线程，但是系统内多个进程可以同时进行，在同一时间内一个主线程只能为一个线程提供服务，为了保证主线程可以空余出更多的计算量为其他进行提供服务，本申请实施例示出的一种显示设备，具体的可以参阅图20，图20为根据一可行性实施例示出的显示设备的结构框图，其中，显示设备至少包括显示器202和控制器201，其中，控制器内设置有存储区2011和处理器2012；存储区2011用于存储显示设备下载的文件。用户可以根据需求将一些文件放置于同一个文件夹内。处理器，用于 执行存储在存储区中的操作系统和应用程序指令或线程，以及根据接收的用户输入指令，来执行各种应用程序、数据和内容的处理，以便最终显示和播放各种音视频内容。具体应用到本实施例示出的方案中，处理器可以调用主线程20121和子线程20122。显示设备的交互流程图可以参阅图28。

本实施提供的技术方案设计的初衷是当文件拷贝时，可以基于当前文件写入量和文件总量实时的计算文件的拷贝进度，并将拷贝进度呈现给用户，以保证用户可以准确的获知文件的拷贝进度。存在一种应用场景，待拷贝文件的文件总量大于目标存储区的剩余存储量，在此情况下无法将待拷贝文件写入目标存储区，基于上述应用场景本申请实施例示出一种显示设备，显示设备在文件拷贝之前可以对待拷贝文件的文件总量和目标存储区的剩余存储量进行统计，并根据统计结果确定是够将待拷贝文件写入目标存储区。具体的，可以参阅图29，图29为根据一可行性实施例示出的显示设备与用户的交互流程图。
