为了提升视觉体验，各种电子设备的屏幕越来越大，更能满足用户在电子设备上同时运行多个任务的需求。
当多个任务以多个窗口显示在显示屏时，用户可以将一个窗口内的文件拖拽到其它窗口，以实现文件共享。但是，目前在对文件拖拽的过程中，只有当用户完成拖拽动作之后才能知道文件是否拖拽成功。并且，当文件拖拽失败时，用户不知道失败的原因，可能会使得用户反复操作，进而使得用户体验较差。
发明内容
本申请提供一种文件拖拽方法及电子设备，用以提升文件拖拽过程中的用户体验。
第一方面，本申请提供一种文件拖拽方法，该方法包括：响应用户的第一操作，显示第一窗口和第二窗口；响应用户在所述第一窗口选择目标文件的图标的第二操作，在所述第一窗口显示第一界面，其中，所述第一界面中包括所述目标文件的图标；响应用户的第三操作，当检测到所述目标文件的图标被从所述第一窗口拖拽到所述第二窗口时，在所述第二窗口显示第一标识信息或第二标识信息；其中，所述第三操作用于将所述目标文件的图标从所述第一窗口拖拽到所述第二窗口，所述第一标识信息用于标识所述目标文件的图标能够添加到所述第二窗口，所述第二标识信息用于标识所述目标文件的图标不能添加到所述第二窗口。
通过上述技术方案，在文件被拖拽到目标窗口时，可以通过标识信息来标识目标窗口是否能够接收被拖拽的文件，这样用户可以直观的看到文件是否拖拽成功。特别在目标窗口不能接收被拖拽的文件时，能够避免用户反复操作，可以提升用户体验。
在一种可能的设计中，所述方法还包括：当检测到所述目标文件的图标被从所述第一窗口拖拽到所述第二窗口时，在所述第二窗口显示第三标识信息，所述第三标识信息用于标识所述目标文件的图标的数量。
在上述技术方案中，可以在文件拖拽到目标窗口时，显示被拖拽的文件数量，这样用户可以直观的看到拖拽的文件数量，能够使得在实际成功拖拽文件个数小于实际拖拽文件个数时，用户能够知道个数遗漏的原因，从而提升用户体验。

所述方法还包括：当检测到所述目标文件的图标被从所述第一窗口拖拽到所述第二窗口时，在所述第二窗口显示第四标识信息，所述第四标识信息用于标识所述第二窗口不能添加所述第二类型的第二文件的图标。
通过上述技术方案，在被拖拽的文件数量为多个时，如果目标窗口只能接收特定文件类型的文件，那么在被拖拽的文件中可能会存在目标窗口不能接收的文件，此时可以显示提示信息，以提醒用户目标窗口不能接收其它类型的文件。
在一种可能的设计中，所述方法还包括：显示第一提示信息，所述第一提示信息用于提示用户所述目标文件的图标处于拖拽状态。
通过上述技术方案，可以在用户选择目标文件之后，显示目标文件处于拖拽状态，这样能够避免用户在操作过程中失误丢手的情况，从而提升用户体验。
在一种可能的设计中，所述方法还包括：若检测到所述目标文件的图标的高度大于第一设定高度，则将所述目标文件的图标的高度调整为第二设定高度，并显示在所述第二窗口，所述第二设定高度为所述第一设定高度的N倍，所述N满足：0<N<1。
通过上述技术方案，可以在目标文件的高度大于设定高度时，对目标文件的高度进行缩放，这样能够便于用户检查文件是否有遗漏，避免窗口过多时，文件拖拽出现混乱的情况发生。

本申请实施例中，应用程序层可包括至少一个应用程序，以两个应用程序为例，其中一个应用程序为发送应用(或者称为拖出应用，即元素拖出时元素所在的应用)，另一个应用程序为接收应用(即接收拖拽元素的应用)。参阅图2B所示，电子设备可检测用户的长按操作进入拖拽处理事件，并存储用户选择的拖拽数据(例如，保存到ClipDescription)，然后通过系统(应用框架层(Framework))ACTION_DRAG_STARTED事件将拖拽数据发送给接收应用。另外，发送应用可在系统回调绘制图层时，绘制角标。这里的角标包括元素数量的图标以及元素是否支持添加到接收窗口的图标。
相应的，接收应用可申明接口，并申明应用的每个控件(或者称为窗口)所能接收的文件类型。当接收应用接收到ACTION_DRAG_STARTED事件之后，可根据ACTION_DRAG_STARTED事件中携带的拖拽信息匹配自身能够接收的文件数量，并保存匹配结果。
当用户将元素拖拽到接收应用的可释放区域(接收应用的界面)时，可接收控件收到ACTION_DRAG_ENTERED通知。然后接收应用向系统反馈匹配结果，系统再将匹配结果传递给发送应用。相应的，发送应用接收到匹配结果后可更新角标。可以理解的是，这里的角标可以理解为下述实施例中文件是否支持添加到接收窗口的图标和拖拽文件的数量。
当拖拽动作离开可释放区域时，接收应用的可接收控件收到ACTION_DRAG_EXITED通知，向系统反馈“离开”通知(即拖拽动作离开接收应用)。然后接收应用向系统反馈“离开”通知，系统再将“离开”通知传递给发送应用。相应的，发送应用接收到“离开”通知后恢复角标。
可以理解的是，元素即为下述实施例中的文件，本申请中有时候两者会混用，应理解，其含义一致。
如图2C所示，为本申请实施例提供的处理流程图，该流程图的具体步骤实现可参阅图2B所示实施例的介绍，此处不再重复赘述。
需要说明的是，当用户触发拖拽动作时，注册了ACTION_DRAG_STARTED广播的可接收控件，可以根据广播中携带的ClipDescription信息(即拖拽信息)，匹配接收控件能够接收的文件数量。
以下实施例以应用在图1所示的手机100所示的架构中为例进行描述。
此外，下述实施例涉及的至少一个，包括一个或者多个；其中，多个是指大于或者等于两个。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
目前，为了满足用户同时处理多个任务的需求，电子设备支持多窗口模式，即可以将多个任务同时显示在一个显示屏上，以避免用户频繁切换窗口的麻烦。在此场景下，用户可以将一个窗口内的文件拖拽到另一个窗口，以实现资源共享。在文件拖拽过程中，由于显示屏上没有提示信息，只有当文件拖拽完成之后，用户才能知道文件是否拖拽成功。如 果文件拖拽失败，用户也无法区分是操作有误还是其它原因，使得用户体验较差。
有鉴于此，本申请实施例提供了一种文件拖拽方法，通过在文件拖拽过程中，实时反馈拖拽状态，例如显示拖拽的状态、拖拽的文件数量以及文件是否支持拖拽等，以提升用户体验。
以下，将结合附图对本申请实施例提供的一种文件拖拽方法进行具体介绍。
如图3所示，为本申请实施例提供的一种文件拖拽方法流程图，参阅图3所示，该方法可包括如下步骤：
S301：电子设备响应用户的第一操作，在显示屏上显示第一窗口和第二窗口。
这里，用户的第一操作可以为用户开启多任务窗口的操作。示例性的，该第一操作可以为触发分屏显示的操作，例如显示屏显示第一应用界面，在此第一应用界面上，电子设备可以响应用户的第一操作，例如沿着显示屏的左边缘向内滑动，调出智慧分屏的应用栏，然后点击分屏应用栏中想要进行分屏的应用图标即可实现分屏。当然可以理解的是，触发分屏显示的操作还可以为其它的手势操作，比如也可以通过下拉通知栏中的快捷开关开启分屏，或者还可以通过语音控制的方式开启分屏等等，本申请对此不作限定。
需要说明的是，分屏显示的两个窗口的大小可以相同，也可以不同，并且，分屏显示的窗口可以以悬浮窗的形式显示在显示屏上。本申请实施例中，第一窗口和第二窗口也可以自由显示在电子设备的显示屏上，本申请对此不作限定。
参阅图4A所示，假设电子设备的显示屏上显示图库的应用界面400，此时用户可沿着界面400的右边缘向内滑动，调出分屏的应用栏，例如显示屏上可显示用户界面410。其中界面410中包括分屏的应用栏411，然后在应用栏411中点击应用图标“电子邮件”412，此时显示屏上可显示用户界面420。这样显示屏上即可显示两个应用窗口，比如包括图库的应用窗口421和电子邮件的应用窗口422。
以下，为了描述方便，可将显示屏上显示的窗口记为“第一窗口”和“第二窗口”。
本申请实施例中，电子设备的显示屏上可显示多个窗口，并且多个窗口可以为一个应用程序的多个窗口，也可以为多个应用程序的多个窗口，本申请对此不作限定。示例性的，显示屏上显示第一窗口和第二窗口。其中，第一窗口可以为第一应用的显示窗口，第二窗口可以为第二应用的显示窗口。另一示例，第一窗口可以为第一应用的第一显示窗口，第二窗口可以为第一应用的第二显示窗口。也就是说，本申请中，可以在两个应用的应用窗口之间拖拽文件，也可以在一个应用的两个应用窗口之间拖拽文件。
需要说明的是，文件可以包括图片、视频、文本、音频等。另外，用户在选择文件时，可以选择一个文件，也可以选择多个文件。
S302：电子设备响应用户在第一窗口的第二操作。
这里的第二操作可以为用户选择文件的操作，示例性的，该第二操作可以为用户在图库中对图片或者视频的长按操作，比如用户长按某一张图片预设时长(例如，2s)之后，可选中该图片。
参阅图4B所示，假设第一窗口为应用程序图库的界面，第二窗口为应用程序邮件的界面。假设用户要将第一窗口的图片拖拽到第二窗口，比如用户在图4B中的(a)所示示意图的图库中选择了两张图片，则可长按选择的图片，然后图库可显示如图4B中的(b)所示的界面，即当用户长按图片之后，图片可处于选择状态，例如图片的右下角可显示对号。
应理解，本申请中的应用窗口可以左右放置，也可以上下放置，本申请对此不作限定。以下实施例中以手机处于横屏状态，且应用为左右放置为例进行介绍。
需要说明的是，当图片处于选择状态时，被选择的图片和未被选择的图片从用户视觉上看起来可能会有所不同，例如，被选择的图片的上层可能会显示一层模糊的层，当然，在实际产品实现时，也可能不显示，本申请对此不作限定。
可以理解的是，步骤S301和步骤S302在实际应用中，并不限定其执行的前后顺序，用户也可以先选择要拖拽的文件，然后开启多任务窗口，本申请对此不作限定。
S303：电子设备响应用户的第三操作，将第一文件从第一窗口拖拽到第二窗口。
这里第三操作可以为用户对第一文件的拖拽操作，例如可以为用户对图片的拖拽操作，也可以为用户对视频的拖拽操作，或者也可以为用户对图片和视频的拖拽操作等，本申请对此不作限定。当然，拖拽操作可以为用户对一张图片的拖拽操作，也可以用户对多张图片的拖拽操作。当用户在第一窗口中选择第一文件之后，可以将在第一窗口选择的文件拖拽到第二窗口。
在一些实施例中，电子设备可以预先保存每一个窗口中支持拖拽的文件。示例性的，假设第一窗口内包括多个文件，比如标识信息为1、2、4分别对应的文件1、文件2、文件4为支持拖拽的文件，标识信息为3、5、6分别对应的文件3、文件5、文件6为不支持拖拽的文件。当然，也可以针对文件类型来区分是否支持拖拽，比如，当文件类型为图片时，支持拖拽；当文件类型为视频时，不支持拖拽。或者，还可以根据文件的格式来区分，例如，当文件的格式为XML格式时，支持拖拽；当文件的格式为JSON格式时，不支持拖拽。或者，还可以根据文件的后缀名来区分是否支持拖拽等，本申请对此不作限定。
由于用户操作时可能会出现失误丢手(可以理解为，松开拖拽状态)，为了避免文件在拖拽过程中的这种问题，本申请实施例中若文件支持拖拽，则可显示提示信息，该提示信息可用于提示文件支持拖拽，且处于拖拽状态。
示例性，参阅图4C所示，用户可在图4B中的(b)所示的示意图中长按(例如，2s)并拖拽所选择的文件，然后文件可进入拖拽状态。示例性的，用户可将选择的文件拖拽到界面上的其它位置，例如图中的示意。此时电子设备的显示屏上可显示图4C所示的提示信息，例如可显示“一个文件支持拖拽，且处于拖拽状态”。
另一示例，若选择的文件不支持拖拽(比如，由于文件太大的原因不支持拖拽)，则也可以显示提示信息，例如可显示“文件不支持拖拽”，或者显示“文件太大，不支持拖拽”等，以避免用户拖拽多次，没有响应，不知道由于什么原因导致的拖拽失败问题，从而提升用户体验。
需要说明的是，上述提示信息可显示在第一窗口，也就是被拖拽文件所在的窗口，以提示用户有文件处于拖拽状态。
S304：电子设备判断第二窗口是否支持接收第一文件。
对于每个窗口而言，窗口内的文件可以拖拽到其它的窗口，相应的，也可以接收用户从其它窗口拖拽的文件。在另一些实施例中，电子设备中可以预先保存每一个窗口所支持接收的文件。示例性的，假设第二窗口为接收窗口，第二窗口支持接收标识信息为1、2、3分别对应的文件1、文件2、文件3，不支持接收标识信息为4、5、6分别对应的文件4、文件5、文件6；或者第二窗口支持接收图片类型的文件，不支持接收视频类型的文件；或者还可以为第二窗口支持接收第一格式(例如，XML)的文件，不支持接收第二格式(例 如，JSON)的文件等，或者，还可以根据文件的后缀名来判断窗口是否支持接收，或者根据文件的大小判断窗口是否支持接收等，本申请对此不作限定。
作为一种可能的实施方式，本申请实施例中针对每一个窗口，可提供一个数据申明接口，该数据声明接口可用于申明窗口能够接收的文件。具体来说，该数据声明接口可以用于声明每个窗口所能够接收的文件类型。示例性，可参阅表1所示，每一个声明接口都可对应一个数据声明。
表1接口与数据声明的对应关系
声明接口 数据声明
接口1 声明窗口1只能接收文本类型的文件
接口2 声明窗口2能够接收文本类型的文件以及图片
接口3 声明窗口3能够接收各种类型的文件
可以理解的是，上述表1仅是一种示意性说明，不同的声明接口可对应不同的数据声明。当然，不同的声明接口也可对应相同的数据声明，本申请对此不作限定。
本申请实施例中，接收窗口可以根据自身窗口的数据声明确定是否能够接收拖拽的文件。比如，拖拽的文件的文件类型属于接收窗口的数据声明范围，则接收窗口可以接收拖拽的文件；若拖拽的文件的文件类型不属于接收窗口的数据声明范围，则接收窗口不能接收拖拽的文件。
S305：若第二窗口支持接收第一文件，则将第一文件添加到第二窗口。
S306：若第二窗口不支持接收第一文件，则在第二窗口显示提示信息。
在一些实施例中，当第二窗口不支持接收第一文件时，可以在第二窗口内显示提示信息，该提示信息用于提示用户第二窗口不支持接收第一文件，以便用户及时了解拖拽状态，避免在拖拽失败时不清楚失败原因多次尝试等问题，进而提升用户体验。
以下以拖拽图库中的文件为例，结合不同场景对该步骤的用户界面示意图进行详细介绍。
场景一：拖拽单张图片时，可以通过在图片上添加标识信息来标识图片是否支持添加到第二窗口。
示例性的，可以通过如图所示的标识来区分图片是否支持添加。例如，当图片支持添加到第二窗口时，图片的左上角可标识“+”；当图片不支持添加到第二窗口时，图片的左上角可标识“\”。
另一示例，可以通过图片的颜色(或者透明度)来标识图片是否支持添加。例如，当图片支持添加到第二窗口时，图片的颜色可以不变，即图片保持原来的颜色；当图片不支持添加到第二窗口时，图片的颜色可以为灰色，或者可以在原图的上层显示一层浮层。
其中，浮层是指位于当前显示界面上的另一个界面，该浮层可以是半透明的，该浮层可以使得用户从视觉上看到的当前显示界面为模糊的。例如，可以在用户拖拽的图片上层显示一层浮层，使得用户从视觉上看到的图片为模糊不清的。
当然，可以理解的是，也可以通过图片左上角的标识和图片的颜色来同时标识图片是否支持添加到接收窗口内。例如，当图片的左上角有“+”标识，且图片的颜色没有变化时，说明该图片支持添加到接收窗口内；当图片的左上角有“\”标识，且图片上有一层半透明的浮层时，可以说明该图片不支持添加到接收窗口内。
举例来说，假设用户在第一窗口选择的图片为支持拖拽的图片，则当用户将图片从第 一窗口拖拽到第二窗口时，如果第二窗口支持添加该图片，则第二窗口上可显示用户所拖拽的图片的缩略图，并且该缩略图上可显示支持添加的标识信息。参阅图5A所示，假设用户从第一窗口沿着图示所示的箭头方向将图片拖拽到第二窗口，此时第二窗口可显示如图5A所示的界面。该界面上可显示有所拖拽的图片，并且左上角可显示有“+”，以提示用户第二窗口可以接收该图片。
可以理解的是，接收窗口的数据声明可以主动声明，也可以不声明。当标识信息“+”所在的区域用绿色标识时，说明接收窗口主动声明其所在窗口的数据声明。当标识信息“+”所在的区域用黄色标识时，说明接收窗口未主动声明其所在窗口的数据声明。当然，上述仅是一种示例，实际产品实现时，也可以用其他颜色来标识。
参阅图5B所示，假设第二窗口不支持添加用户所拖拽的图片，则当用户从第一窗口沿着图示所示的箭头方向将图片拖拽到第二窗口时，第二窗口内可显示如图5B所示的界面。该界面上可显示有所拖拽的图片图，并且左上角可显示有“\”，以提示用户第二窗口不能接收该图片。
可以理解的是，上述示意图中仅是一种示意，在实际产品实现时，如果第二窗口不支持接收用户所拖拽的图片，则当图片被拖拽到第二窗口时，第二窗口上显示的图片上层可以是灰色的，并且标识信息“\”所在的圆形区域也是灰色的。这种显示方式可以使得用户直观的看到接收窗口不能添加所拖拽的图片，能够提升用户体验。
场景二：对多张图片进行拖拽时，显示拖拽的图片数量。
本申请实施例中，当拖拽多张图片时，可以在图片的右上角上添加标识信息，该标识信息用于标识用户选择的图片的数量。当然，如果拖拽一张图片，也可以在图片的右上角添加标识信息，例如显示数字“1”，本申请对此不作限定。
需要说明的是，在本申请实施例中，确定拖拽的文件数量的标识信息(例如，数字)，是电子设备的系统级能力，并不是应用程序级的能力。
可以理解的是，在图片的左上角添加标识信息来标识图片是否支持添加到接收窗口以及在图片右上角添加标识信息来标识图片的数量仅是一种示意性说明，例如，也可以在图片的左上角添加数字，以标识用户选中的图片数量，或者也可以在图片的左下角或者右下角添加数字，以标识用户选中的图片数量等，本申请对此不作限定。
在另一些实施例中，标识信息还可以在距离图片的左上角/左下角/右下角/右上角一定距离的位置处，本申请对此不作限定。
参阅图6A所示，假设用户在图库所在的窗口选择了多张图片，例如图6A中的(a)所示，选择了2张图片，然后用户长按多张图片的任意一张图片，使得图片处于拖拽状态，例如可拖拽到如图6A中的(b)所示的位置。然后用户可将多张图片沿着图中所示的箭头方向将多张图片拖拽到邮件所在的窗口。此时如果邮件所在的窗口支持接收多张图片，则可显示如图6A中的(c)所示的示意图。即若接收窗口支持添加所拖拽的图片，则可在接收窗口显示支持添加文件的标识信息以及文件数量的标识信息，例如可显示“+”和“2”。其中，“+”表示邮件所在的窗口支持添加拖拽的图片，“2”表示拖拽的图片数量为2张。
如果邮件所在的窗口不支持接收多张图片，则可显示如图6A中的(d)所示的示意图。即若接收窗口不支持添加所拖拽的图片，则可在接收窗口显示不支持添加文件的标识信息以及文件数量的标识信息，例如可显示“\”和“2”。其中，“\”表示邮件所在的窗口不支持添加拖拽的图片，“2”表示拖拽的图片数量为2张。
可以理解的是，图6A中的(d)所示的示意图中，图片上层的斜线仅是一种示意，在实际产品时，该图片可能是半透明的，本申请对此不作限定。
场景三：对多种文件类型的多个文件拖拽时，对于不支持拖拽的文件，显示提示信息。
示例性的，假设用户选中的文件包括多个，且包括不同的文件类型(比如拖拽的文件包括图片和视频两种类型)，如果接收窗口仅支持添加图片，那么在拖拽图片和视频到第二窗口之后，第二窗口内可显示提示信息，比如可显示“不支持添加视频”的提示信息。
举例来说，参阅图6B所示，假设用户在图库中选择了一张图片和一个视频，例如图6B中的(a)所示，当用户将选择的一张图片和一个视频沿着图示的箭头方向拖拽到邮件所在的窗口之后，用户可丢手，即松开拖拽状态之后，如果邮件所在的窗口不支持添加视频，则可将用户选择的图片加载并显示在邮件所在的窗口，并且显示“不支持添加视频”的提示信息，例如可参阅图6B中的(b)所示。
场景四：对于文本内容拖拽时，可以根据文本内容的高度对显示的文本内容的高度进行缩放。
作为一种可能的实现方式，对于文本内容拖拽时，如果文本内容的高度大于设定高度(例如，记为第一设定高度)时，可在拖拽时可以将文本内容的进行缩放，例如缩放为第二设定高度。其中，第一设定高度和第二设定高度之间的关系可以为：第二设定高度为第一设定高度的N倍，0<N<1。示例性的，当文本内容的高度<＝第一设定高度(比如，屏幕高度的30％)时，可以不缩放文本内容；当文本内容的高度>第一设定高度(比如，屏幕高度的30％)时，可以将文本内容缩放到屏幕高度的30％进行显示，这样能够避免文本内容过高时，遗漏信息，能够方便用户检查。
举例来说，参阅图6C所示，假设用户在应用程序备忘录中选择了一段文字(比如，文本内容高度大于设定高度)，例如图6C中的(a)所示，用户可以长按备忘录中的一段文字，使得文字进入拖拽状态。然后用户可沿着图示箭头方向将备忘录中选择的文字拖拽到邮件的编辑界面。例如，当拖拽到邮件的编辑界面后，文字的高度可以以文本内容实际高度的30％显示在用户的可视化界面上，例如图6C中的(b)所示。也就是说，当文本拖拽到邮件的编辑界面后，邮件的编辑界面显示的文本内容的高度为文本内容实际高度的30％。
通过本申请实施例的方案，可以对文件拖拽状态进行实时反馈，方便用户根据拖拽状态对拖拽过程进行控制，并且能够预判拖拽结果，提升用户的操作友好性。
基于上述实施例，如图7所示，本申请实施例还提供一种文件拖拽方法，参阅图7所示，该方法可包括如下步骤：
S701：响应用户的第一操作，显示第一窗口和第二窗口。
S702：响应用户在第一窗口选择目标文件的图标的第二操作，在第一窗口显示第一界面。
其中，所述第一界面中包括目标文件的图标。
S703：响应用户的第三操作，当检测到目标文件的图标被从第一窗口拖拽到第二窗口时，在第二窗口显示第一标识信息或第二标识信息。
其中，所述第三操作用于将所述目标文件的图标从所述第一窗口拖拽到所述第二窗口，所述第一标识信息用于标识所述目标文件的图标能够添加到所述第二窗口，所述第二标识 信息用于标识所述目标文件的图标不能添加到所述第二窗口。
