背景技术
随着智能终端的屏幕越来越大、CPU(Central Processing Unit，中央处理器)、内存、GPU(Graphics Processing Unit，图形处理器)等硬件功能越来越强大，用户对应用的需求也越来越高，例如用户希望在操作其他应用的同时能够观看视频。目前，如果终端在运行一个应用的同时想要运行视频应用，终端是需要将当前运行应用的相关操作暂停，或者关闭当前运行应用的应用界面，然后才能切换到另一个应用的应用界面。例如，当用户玩游戏的时候，需要观看视频，用户需要暂停或退出正在玩的游戏才能观看视频；或者，通过设置视频应用和其他应用的界面的显示大小，才能同时显示视频应用和其他应用，用户需要在各个应用的应用界面之间来回切换，给用户的操作带来不便，且并不能实现在显示其他应用的用户界面的同时播放视频。此外，现有技术方案中，视频播放模式的切换主要采用的是隐藏或者显示视图的方式，这种方式性能很低，且视图不能及时绘制，容易导致切换模式不流畅等问题。
发明内容

上述说明仅是本发明技术方案的概述，为了能够更清楚了解本发明的技术手段，而可依照说明书的内容予以实施，并且为了让本发明的上述和其它目的、特征和优点能够更明显易懂，以下特举本发明的具体实施方式。

具体实施方式
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。
本发明的发明人在使用一些应用(例如，游戏应用)的过程中发现，在使用这些应用的时候，并不能在显示应用的用户界面的同时还播放视频，即，用户不能在使用这些应用的同时还能观看视频，用户需要另外开启视频应用，然而，视频应用和其他应用并不能同时在移动终端屏幕上显示，在PC终端也需要通过设置视频应用和其他应用的界面的显示大小，才能同时显示视频应用和其他应用，若用户想要对视频应用或其他应用进行操作时，需要将光标定位到相应的应用，这样很容易造成使用不便，为了解决上述问题，发明人经过创造性的劳动，提出了利用寄生工具包，将寄生工具包与主应用预先绑 定，以提供在主应用的用户界面中播放视频的功能的解决方案。
其中，主应用是一独立的应用，该应用可以独立实现相应的功能，不需要依赖于任何其他的应用，例如，游戏应用，用户在启动游戏应用后，便可以在游戏应用所提供的用户界面上玩游戏。
而该寄生工具包需要依赖于主应用才可以实现相应的功能，需要主应用调用该寄生工具包的API接口才能实现寄生工具包相应的功能，例如，以在游戏应用播放视频为例，在用户玩游戏的时候可以同时播放视频，这里游戏应用为主应用，播放视频是寄生工具包所实现的功能。
在播放视频的过程中，用户可以根据需要选择视频播放模式，目前，视频播放模式的切换主要采用的是隐藏或者显示视图的方式，这种方式性能很低，且视图不能及时绘制，容易导致切换模式不流畅等问题。
图1示出了根据本发明一个实施例的利用寄生工具包实现的视频播放模式切换方法的流程图。如图1所示，该方法包括以下步骤：
步骤S100，根据用户触发的视频播放的行为，创建第一悬浮窗并设置第一悬浮窗的布局参数，在第一悬浮窗内嵌入视频播放器。
本发明实施例在通过创建悬第一悬浮窗(Floatwindow)的方式实现视频播放。第一悬浮窗是存在终端屏幕最上层的浮动窗口，第一悬浮窗不隶属于Activity界面，也不受Activity界面的覆盖影响，但与Activity的生命周期相同。本发明实施例中，第一悬浮窗由寄生工具包创建。当用户想要在主应用中观看视频时，可以通过触发视频播放的方式启动播放视频，在检测到用户的触发行为后，根据用户的该行为，创建Floatwindow。
Floatwindow的创建涉及到WindowManager接口，实现类有WindowManagerImpl，CompatModeWrapper，LocalWindowManager。具体地，寄生工具包的代码启动一个Service，然后在Service中创建第一悬浮窗。在创建第一悬浮窗时，需要定义第一悬浮窗的布局，创建第一悬浮窗设置布局参数的对象；设置第一悬浮窗的位置参数和尺寸参数(包含width和height)。第一悬浮窗的位置参数和尺寸参数决定了第一悬浮窗以预设尺寸显示在终端屏幕的预设位置。
在创建第一悬浮窗之后，在第一悬浮窗内嵌入视频播放器，该视频播放器可以用于显示视频流。
步骤S101，依据第一悬浮窗的布局参数对第一悬浮窗进行布局及展现。
在根据步骤S100设置第一悬浮窗的布局参数后，依据所设置的布局参数对第一悬浮窗进行布局，并展现布局后的第一悬浮窗，例如，设置第一悬浮 窗的尺寸参数为width：80、height：100(以像素为单位)，这样展现给用户的就是一个100*80的悬浮窗。
步骤S102，在呈现主应用的用户界面的同时在第一悬浮窗内播放服务器提供的视频流。
具体地，将服务器提供的视频流传输给视频播放器，在第一悬浮窗内播放该视频流，从而在呈现主应用的用户界面的同时播放视频流。
步骤S103，根据用户触发的切换视频播放模式的行为，修改第一悬浮窗的布局参数，根据修改后的布局参数对第一悬浮窗进行重新布局及展现。
在本发明实施例中，视频播放模式主要包括：全屏模式、极简模式和默认模式，其中，全屏模式指视频画面占用整个终端屏幕，视频画面将完全覆盖主应用的用户界面，极简模式中视频画面覆盖主应用的用户界面的部分最小，默认模式中视频画面将覆盖主应用的用户界面的一部分，然而默认模式中视频画面小于全屏模式下视频画面，但大于极简模式下的视频画面。
本发明实施例中，在视频播放器上会显示切换按钮，可以通过点击切换按钮进行视频播放模式的切换，对于有多种视频播放模式可供用户选择的情况，可以通过选择下拉菜单的方式供用户选择具体的视频播放模式。检测到用户选择下拉菜单中视频播放模式的操作，将检测到的用户选择下拉菜单中视频播放模式的操作作为用户的触发行为，当然，还可以采用其他方式，本实施例对此不作具体限定。
根据用户触发的切换视频播放模式的行为，对第一悬浮窗的布局参数进行修改，例如，修改为width：150、height：120，根据修改后的布局参数对第一悬浮窗进行重新布局，展现给用户的就是一个120*150的悬浮窗。
根据本发明上述实施例提供的方法，通过修改第一悬浮窗的布局参数，根据修改后的布局参数对第一悬浮窗进行重新布局及展现，实现了视频播放模式的切换，克服了现有技术中，采用隐藏或者显示视图的方式，导致性能很低，且视图不能及时绘制，切换模式不流畅等问题。进一步的，可通过第一悬浮窗播放视频实现了呈现主应用的用户界面的同时播放视频，解决了用户只能单独使用其他应用或视频应用，而不能在操作其他应用时同时显示视频应用的界面的缺陷，克服了现有技术中当需要操作其他应用或视频应用时，都需要切换到相应的应用，导致操作不便的问题，大大提高了用户操作的简便性，节省用户时间。
图2示出了根据本发明另一个实施例的利用寄生工具包实现的视频播放模式切换方法的流程图。如图2所示，该方法包括以下步骤：
步骤S200，根据用户触发的视频播放的行为，创建第一悬浮窗并设置第一悬浮窗的布局参数，在第一悬浮窗内嵌入视频播放器。
本发明实施例在通过创建悬第一悬浮窗(Floatwindow)的方式实现视频播放。第一悬浮窗是存在终端屏幕最上层的浮动窗口，第一悬浮窗不隶属于Activity界面，也不受Activity界面的覆盖影响，但与Activity的生命周期相同。本发明实施例中，第一悬浮窗由寄生工具包创建。当用户想要在主应用中观看视频时，可以通过触发视频播放的方式启动播放视频，在检测到用户的触发行为后，根据用户的该行为，创建Floatwindow。
Floatwindow的创建涉及到WindowManager接口，实现类有WindowManagerImpl，CompatModeWrapper，LocalWindowManager。具体地，寄生工具包的代码启动一个Service，然后在Service中创建第一悬浮窗。在创建第一悬浮窗时，需要定义第一悬浮窗的布局，创建第一悬浮窗设置布局参数的对象；布局参数至少包括窗口尺寸参数，例如，设置第一悬浮窗的位置参数和尺寸参数(包含width和height)。第一悬浮窗的位置参数和尺寸参数决定了第一悬浮窗以预设尺寸显示在终端屏幕的预设位置。
在创建第一悬浮窗之后，在第一悬浮窗内嵌入视频播放器，该视频播放器可以用于显示视频流。其中，视频播放器通过第一窗口视图来实现。为了能够使该悬浮窗显示用户所启动的视频服务的用户界面，在创建悬浮窗之后，在悬浮窗内嵌入第一窗口视图，该第一窗口视图用于绘制视频界面。这里第一窗口视图可以为任何能够显示视频服务所提供的用户界面的视图，本发明对此不作限制。本实施例以第一窗口视图为surfaceview视图为例进行说明。
在Android系统中，surfaceview具有独立的绘图表面，它不与其宿主窗口共享同一个绘图表面。由于具有独立的绘图表面，因此surfaceview的用户界面可在一个独立的线程中进行绘制，而且又不会占用主线程资源。surfaceview一方面可以实现复杂而高效的UI绘制，另一方面又不会导致用户输入得不到及时响应。因此，使用surfaceview作为窗口视图嵌入到悬浮窗中，可以实现复杂和高效的绘制。
为了克服由于第一窗口视图不能及时刷新而导致的第一窗口视图被透到终端屏幕的缺陷，在悬浮窗内嵌入第二窗口视图，设置第二窗口视图与第一窗口视图的相对位置关系，设定第二窗口视图位于第一窗口视图之下，即位于视频播放器之下，并且第二窗口视图为非透明的背景视图，从而能够解决第一窗口视图被透到终端屏幕的问题。
步骤S201，依据第一悬浮窗的布局参数对第一悬浮窗进行布局及展现。
在根据步骤S200设置第一悬浮窗的布局参数后，依据所设置的布局参数 对第一悬浮窗进行布局，并展现布局后的第一悬浮窗，例如，设置第一悬浮窗的尺寸参数为width：80、height：100，这样展现给用户的就是一个100*80的悬浮窗。
步骤S202，在呈现主应用的用户界面的同时在第一悬浮窗内播放服务器提供的视频流。
具体地，在将服务器提供的视频流传输给第一窗口视图之后，寄生工具包控制第一窗口视图在其绘图表面绘制视频流对应的视频界面，在所绘制的视频界面内显示视频流，实现了在呈现主应用的用户界面的同时在悬浮窗内播放视频流。
步骤S203，根据用户触发的切换视频播放模式的行为，查找切换后的视频播放模式对应的布局参数。
在本发明实施例中，视频播放模式主要包括：全屏模式、极简模式和默认模式，其中，全屏模式指视频画面占用整个终端屏幕，视频画面将完全覆盖主应用的用户界面，极简模式中视频画面覆盖主应用的用户界面的部分最小，默认模式中视频画面将覆盖主应用的用户界面的一部分，然而默认模式中视频画面小于全屏模式下视频画面，但大于极简模式下的视频画面。
本发明实施例中，在视频播放器上会显示切换按钮，可以通过点击切换按钮进行视频播放模式的切换，对于有多种视频播放模式可供用户选择的情况，可以通过选择下拉菜单的方式供用户选择具体的视频播放模式。检测到用户选择下拉菜单中视频播放模式的操作，将检测到的用户选择下拉菜单中视频播放模式的操作作为用户的触发行为，当然，还可以采用其他方式，本实施例对此不作具体限定。
根据用户触发的切换视频播放模式的行为，在预设的布局参数库中，查找切换后的视频播放模式对应的布局参数，该布局参数包含了切换后，第一悬浮窗的窗口尺寸参数等，窗口的宽和高，以及第一悬浮窗的位置参数，位置参数决定了第一悬浮窗在终端屏幕的位置。
步骤S204，依据切换后的视频播放模式对应的布局参数修改第一悬浮窗的布局参数。
步骤S205，根据修改后的布局参数对第一悬浮窗进行重新布局及展现。
在根据步骤S203查找到切换后的视频播放模式对应的布局参数后，依据该参数，对第一悬浮窗的布局参数进行修改，使第一悬浮窗以修改后的窗口尺寸参数进行展现，若在修改第一悬浮窗的布局参数时，修改了第一悬浮窗的位置参数，在修改后，使悬浮窗以修改后的窗口尺寸参数对应的尺寸显示 在终端屏幕的位置参数对应的位置。例如修改悬浮窗的窗口高度(height)或窗口宽度(width)，使悬浮窗缩小，如缩小为原来的三分之一，从而为主应用留出更大的显示空间。
在本实施例中，当视频播放模式切换到极简模式时，不仅可以显示视频还可以聊天等，以聊天为例，在极简模式下，通过创建两个悬浮窗，一个用于播放视频，一个用于聊天。
其中，第一播放模式可以为全屏模式或默认模式，第二播放模式为极简模式。
在本实施例的一个可能的实现方式中，若视频播放模式由第一播放模式切换到第二播放模式，方法还包括：创建用于展现用户交互界面的第二悬浮窗，设置第二悬浮窗的布局参数；依据第二悬浮窗的布局参数对第二悬浮窗进行布局及展现。
具体地，若视频播放模式由全屏模式或默认模式切换到极简模式，由于极简模式需要采用两个悬浮窗才能完成用户交互，因此，需要创建用于展现用户交互界面的第二悬浮窗，定义第二悬浮窗的布局，创建第二悬浮窗设置布局参数的对象；设置第二悬浮窗的位置参数和尺寸参数(包含width和height)。第二悬浮窗的位置参数和尺寸参数决定了第二悬浮窗以预设尺寸显示在终端屏幕的预设位置。在设置第二悬浮窗的布局参数后，依据所设置的布局参数对第二悬浮窗进行布局，并展现布局后的第二悬浮窗，例如，设置第二悬浮窗的尺寸参数为width：50、height：20，这样展现给用户的就是一个20*50的悬浮窗。
在本实施例的一个可能的实现方式中，若视频播放模式由第二播放模式切换到第一播放模式，方法还包括：修改第二悬浮窗的布局参数，使得第二悬浮窗被布局到终端屏幕之外。
具体地，若视频播放模式由极简模式到全屏模式或默认模式切换，由于全屏模式或默认模式下第一悬浮窗用于播放视频，这样就不需要创建两个悬浮窗，现有技术中采用的是隐藏第二悬浮窗，显示全屏模式或默认模式的第一悬浮窗口的方式，实现视频播放模式的切换，这种方式性能很低，且对应的视图不能及时绘制，容易导致切换模式不流畅等问题，为了克服这类问题，通过修改第二悬浮窗的布局参数，使得第二悬浮窗被布局到终端屏幕之外，例如修改第二悬浮窗的位置参数为负值。
根据本发明上述实施例提供的方法，通过修改第一悬浮窗的布局参数，根据修改后的布局参数对第一悬浮窗进行重新布局及展现，实现了视频播放模式的切换，克服了现有技术中，采用隐藏或者显示视图的方式，导致性能 很低，且视图不能及时绘制，切换模式不流畅等问题。进一步的，可通过第一悬浮窗播放视频实现了呈现主应用的用户界面的同时播放视频，解决了用户只能单独使用其他应用或视频应用，而不能在操作其他应用时同时显示视频应用的界面的缺陷，克服了现有技术中当需要操作其他应用或视频应用时，都需要切换到相应的应用，导致操作不便的问题，大大提高了用户操作的简便性，节省用户时间。
图3示出了根据本发明一个实施例的利用寄生工具包实现的视频播放模式切换装置的结构框图。如图3所示，该装置包括：创建模块300、嵌入模块310、布局展现模块320、呈现模块330和修改模块340。

嵌入模块310，适于在第一悬浮窗内嵌入视频播放器。

根据本发明上述实施例提供的装置，通过修改第一悬浮窗的布局参数，根据修改后的布局参数对第一悬浮窗进行重新布局及展现，实现了视频播放模式的切换，克服了现有技术中，采用隐藏或者显示视图的方式，导致性能很低，且视图不能及时绘制，切换模式不流畅等问题。进一步的，可通过第一悬浮窗播放视频实现了呈现主应用的用户界面的同时播放视频，解决了用户只能单独使用其他应用或视频应用，而不能在操作其他应用时同时显示视频应用的界面的缺陷，克服了现有技术中当需要操作其他应用或视频应用时，都需要切换到相应的应用，导致操作不便的问题，大大提高了用户操作的简便性，节省用户时间。
在此提供的算法和显示不与任何特定计算机、虚拟系统或者其它设备固有相关。各种通用系统也可以与基于在此的示教一起使用。根据上面的描述，构造这类系统所要求的结构是显而易见的。此外，本发明也不针对任何特定编程语言。应当明白，可以利用各种编程语言实现在此描述的本发明的内容，并且上面对特定语言所做的描述是为了披露本发明的最佳实施方式。
在此处所提供的说明书中，说明了大量具体细节。然而，能够理解，本发明的实施例可以在没有这些具体细节的情况下实践。在一些实例中，并未详细示出公知的方法、结构和技术，以便不模糊对本说明书的理解。
类似地，应当理解，为了精简本公开并帮助理解各个发明方面中的一个或多个，在上面对本发明的示例性实施例的描述中，本发明的各个特征有时被一起分组到单个实施例、图、或者对其的描述中。然而，并不应将该公开的方法解释成反映如下意图：即所要求保护的本发明要求比在每个权利要求中所明确记载的特征更多的特征。更确切地说，如下面的权利要求书所反映的那样，发明方面在于少于前面公开的单个实施例的所有特征。因此，遵循具体实施方式的权利要求书由此明确地并入该具体实施方式，其中每个权利要求本身都作为本发明的单独实施例。
本领域那些技术人员可以理解，可以对实施例中的设备中的模块进行自适应性地改变并且把它们设置在与该实施例不同的一个或多个设备中。可以把实施例中的模块或单元或组件组合成一个模块或单元或组件，以及此外可以把它们分成多个子模块或子单元或子组件。除了这样的特征和/或过程或者单元中的至少一些是相互排斥之外，可以采用任何组合对本说明书(包括伴随的权利要求、摘要和附图)中公开的所有特征以及如此公开的任何方法或者设备的所有过程或单元进行组合。除非另外明确陈述，本说明书(包括伴随的权利要求、摘要和附图)中公开的每个特征可以由提供相同、等同或相似目的的替代特征来代替。
此外，本领域的技术人员能够理解，尽管在此所述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本发明的范围之内并且形成不同的实施例。例如，在下面的权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
本发明的各个部件实施例可以以硬件实现，或者以在一个或者多个处理器上运行的软件模块实现，或者以它们的组合实现。本领域的技术人员应当理解，可以在实践中使用微处理器或者数字信号处理器(DSP)来实现根据本发明实施例的利用寄生工具包实现的视频播放模式切换设备中的一些或者全部部件的一些或者全部功能。本发明还可以实现为用于执行这里所描述的方法的一部分或者全部的设备或者装置程序(例如，计算机程序和计算机程序产品)。这样的实现本发明的程序可以存储在计算机可读介质上，或者可以具有一个或者多个信号的形式。这样的信号可以从因特网网站上下载得到，或者在载体信号上提供，或者以任何其他形式提供。
例如，图4示出了可以实现根据本发明的利用寄生工具包实现的视频播放模式切换方法的计算设备。该计算设备传统上包括处理器410和以存储器420形式的程序产品或者可读介质。存储器420可以是诸如闪存、EEPROM(电可擦除可编程只读存储器)、EPROM或者ROM之类的电子存储器。存储器420具有用于执行上述方法中的任何方法步骤的程序代码431的存储空间430。例如，用于程序代码的存储空间430可以包括分别用于实现上面的方法中的各种步骤的各个程序代码431。这些程序代码可以从一个或者多个程序产品中读出或者写入到这一个或者多个程序产品中。这些程序产品包括诸如存储卡之类的程序代码载体。这样的程序产品通常为如参考图5所述的便携式或者固定存储单元。该存储单元可以具有与图4的计算设备中的存储器420类似布置的存储段、存储空间等。程序代码可以例如以适当形式进行压缩。通常，存储单元包括可读代码431’，即可以由例如诸如410之类的处理器读取的代码，这些代码当由计算设备运行时，导致该计算设备执行上面所描述 的方法中的各个步骤。
应该注意的是上述实施例对本发明进行说明而不是对本发明进行限制，并且本领域技术人员在不脱离所附权利要求的范围的情况下可设计出替换实施例。在权利要求中，不应将位于括号之间的任何参考符号构造成对权利要求的限制。单词“包含”不排除存在未列在权利要求中的元件或步骤。位于元件之前的单词“一”或“一个”不排除存在多个这样的元件。本发明可以借助于包括有若干不同元件的硬件以及借助于适当编程的计算机来实现。在列举了若干装置的单元权利要求中，这些装置中的若干个可以是通过同一个硬件项来具体体现。单词第一、第二、以及第三等的使用不表示任何顺序。可将这些单词解释为名称。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分步骤可以通过程序来指令相关的硬件来完成，该程序可以存储于一计算机可读取存储介质中，比如ROM/RAM、磁碟、光盘等。
以上所述的具体实施例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限定本发明的保护范围，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
