Embodiment 2
Each step based on the method for Android operating system control video playback among the embodiment 1 can realize by the AppWidget technology based on Android, its ultimate principle is described below: be to support little of Widget() exploitation of type application, Android system (Android 1.5 SDK) has increased the AppWidget framework, it provides to the developer, and API is convenient to develop mobile Widget at the Android platform, and the user can carry out with the Widgets of exploitation alternately on the table.AppWidget is a special view, by control process creation and maintenance, and draws on the desktop main screen.I.e. control process is responsible for determining what shows, and the desktop main screen is responsible for concrete the demonstration.The control process is transmitted the RemoteView object to main screen, and this RemoteView object is resolved and drawn to main screen.The RemoteView class is the class in the android.widget bag, and it has been described and can encapsulate the layout information of AppWidget in RemoteView at the view structure of other process demonstration, and layout information is described in the layout resource file.
The structural drawing of AppWidget framework as shown in Figure 3, the AppWidget here just is embedded into a kind of method in the window of outer process to the control of a process.AppWidget refers to the place of working control Widget, and Widget is not an independent user interface program, and it must colonize in certain program (Activity).If program will support the Widget parasitism will support AppWidgetHost, desktop programs (Launcher) is exactly to have realized this interface.AppWidgetProvider is the interface that the AppWidget supplier need to realize, it is actually a BroadcastReceiver.
The functional overview of main class is as shown in table 1 in the AppWidget framework.
| Class | Describe |
| AppWidgetHost | Provide mutual with AppWidgetService, for holding the container of Widget.AppWidgetHost in the Android system is exactly the desktop main screen, can be embedded into Widget among its UI |
| AppWidgetHostView | Be the container that depends on of AppWidget view, AppWidget shows at desktop by AppWidgetHostView. |
| AppWidgetProvider | A convenient class helps realize AppWidgetProvider, inherits in BroadcastReceiver, possesses all functions of radio receiver |
| AppWidgetManager | Upgrade the state of AppWidget, the information of the AppWidget Provider that obtains installing and the correlation behavior of other AppWidget |
| AppWidgetProviderInfo | The metadata of AppWidget has been described some information of AppWidget, comprises renewal frequency, layout etc.Related fields in this class is described under the xml catalogue in the xml file of AppWidget information＜appwidget-provider〉attribute of mark. |
| AppWidgetPicker | An activity, demonstration can be added the AppWidget tabulation of desktop to, start with AppWidgetManager.ACTION_APPWIDGET |
| AppWidgetService | Be the core classes of AppWidget, belong to one of system service, be responsible for the management work of Widgets, comprise the loading, deletion, timed events of Widget etc., AppWidgetService needs self-starting during start.Its purpose mainly is the coupling of untiing between AppWidgetProvider and the AppWidgetHost.If the relation of AppWidgetProvider and AppWidgetHost is fixing in the dust, Widget just can't show in the process arbitrarily. |
Table 1
Based on the AppWidget technology of the Android of above-mentioned introduction, can design a kind of concrete method based on Android operating system control video playback, specifically may further comprise the steps:
Step 101, in the master routine of described client, create a LetvWidget class, make it inherit the AppWidgetProvider class, and covering the onUpdate method, the class of the background service of the described client of startup is to obtain the video data of described video from server end in this onUpdate method.
The concrete meaning of here " AppWidgetProvider ": inherit from BroadcastRecevier reception notification when AppWidget uses update, enable, disable and delete.Wherein, onUpdate, onReceive are the most frequently used methods that arrives, and they receive update notification.The concrete meaning of " covering ": if in subclass, define a method, its title, return type and parameters signatures just in time with parent in title, return type and the parameters signatures of certain method be complementary, can say so, the method for subclass has covered the method for parent.The concrete meaning of " onUpdate " method here: call when generating on the table for assembly, and New Parent UI(User Interface more, user interface)." class of background service " just refers to the service service of unbounded face, is used for obtaining the data of concrete demonstration.
In this way, the LetvWidget class that creates in the step 101, owing to inheriting from the AppWidgetProvider class, the class of background service that therefore can be by starting described client in the onUpdate method is to obtain the video data of described video from server end.Obtain after the video data, can process it, form the essential information of described video and be presented on described little the Widget.
Further, in the AndroidMenifest.xml of described Android operating system, add the receiver label, make it point to the LetvWidget class.
Here " AndroidMenifest.xml " is explained as follows: Android starts before the new application component, and it must know that this assembly exists really.Therefore, application program has been stated its all components in the Manifest file.This Manifest file together has been packaged in the Android bag in company with application code, resource, and this bag is exactly the .apk file of often mentioning.The Manifest file is a structurized XML file, all is named as AndroidManifest.xml in all application programs.It also has many other functions except the assembly of statement application program, and for example, the storehouse that the statement application program need to connect (except the Android storehouse of acquiescence) also has some authorities of identification application expectation etc.The main task of Manifest file still provides the module information of application program for Android.
Step 102, LetvLayout class of definition in the master routine of described client, make it inherit the RelativeLayout class, this LetvLayout class is used for defining the size of described desktop viewing area, and (here " RelativeLayout " refers to relative layout, and child control can carry out relative layout with parameter according to they set reference controls.Can be father's control with reference to control, can be other child controls also, but the control that is referenced must define before the control with reference to it);
(windowing mechanism of whole Android is based on one and is called WindowManager here by the WindowManager class in the master routine of described client, this interface can add view to screen, also can delete view from screen) control described desktop viewing area makes it always be presented at the top of described main screen when opening.
Wherein, in the step 102, utilizing the onTouchEvent method of described LetvLayout class (also is the callback method of touch event, when screen has touch event, the method will be called) pounce on the action that drags of catching the user, to control the display position of described desktop viewing area, described desktop viewing area can be dragged arbitrarily.
In this way, the LetvLayout class of definition in the step 102 owing to inheriting from the RelativeLayout class, therefore can adopt the mode of relative layout to define described desktop viewing area (such as size etc.); Can pounce on the action that drags of catching the user by the onTouchEvent method of described LetvLayout class, described desktop viewing area can be dragged arbitrarily; The WindowManager class is then controlled described desktop viewing area always is presented at described main screen when opening the top.The top of main screen can directly be opened and be presented in the desktop viewing area of this definition when needs are opened, to make things convenient for the user to play and to watch video.
Step 103, (control for example is button, text box and so on etc. here in response to the user click action of described little upper control (for example selecting control 4) to be selected described video, when clicking the control on the Widget this moment, client can send request to server, then server returns corresponding data to client), by described little the played data of obtaining selected video that creates in the step 1; (" intent " Chinese is intention to mode by intent here, pass through intent, application program can be to certain request of Android system expression or hope, Android can respond by suitable assembly according to the content choice of intent, this moment, it can pass to the assembly that calls with intent, and finish calling of assembly, the description that the intent object is abstract the operation that will carry out, the content of its description comprises component Name, action, data, classification, additional information and zone bit etc.) the desktop viewing area of definition in the opening steps 2, and selected played data passed to described desktop viewing area to play selected video.
In this way, control (for example selecting control 4) in the step 103 on to described little is when carrying out click action, can be by described little the played data of obtaining described video, directly open the desktop viewing area of definition this moment by the mode of intent, and selected played data is passed to described desktop viewing area to play selected video.Because here after obtaining the played data of described video by little, directly to play selected video by self-defining desktop viewing area (also being video display area), do not need to use other playing programs (such as video jukebox software of installing on the client etc.) to cooperate the broadcast of video, therefore the efficient of its video playback is higher, carries out efficient better.
Corresponding with the method for embodiment 1, as shown in Figure 4, the invention allows for a kind of system based on Android operating system control video playback, it is characterized in that, comprising:
