墙纸更改事件 [英] Wallpaper change event

问题描述

我可以得到一个广播接收机墙纸更改事件？
我需要的，如果用户更改墙纸检测。
我怎么能这样做呢？

Can I get a wallpaper changed event in a broadcast receiver? I need to detect if the user changed the wall paper. How could I do it?

我在做什么是这样的：
我有全自动改变墙纸的应用程序。
如果用户手动将其使用不同的aplication改变，我想注意到它，并询问用户，如果他/她要添加新的墙纸到列表在我的应用

What I am doing is this: I have an app that changes wallpaper automaticly. If the user changes it manually using a different aplication I would like to notice it and ask the users if he/she wants to add that new wallpaper to the list in my application

推荐答案

有只适用于当墙纸图像变化的广播：<一href=\"http://developer.android.com/reference/android/content/Intent.html#ACTION_WALLPAPER_CHANGED\">http://developer.android.com/reference/android/content/Intent.html#ACTION_WALLPAPER_CHANGED

There is only a broadcast for when a wallpaper image changes: http://developer.android.com/reference/android/content/Intent.html#ACTION_WALLPAPER_CHANGED

要做到你想要什么，你将需要以此来确定更多的逻辑，如果墙纸已更改为东西，除了图像：<一href=\"http://developer.android.com/reference/android/app/WallpaperManager.html#getWallpaperInfo\">http://developer.android.com/reference/android/app/WallpaperManager.html#getWallpaperInfo()

To do what you want, you will need to have more logic to use this to determine if the wallpaper has been changed to something besides an image: http://developer.android.com/reference/android/app/WallpaperManager.html#getWallpaperInfo()

要说句实话，如果你制作的是要改变壁纸，你真的应该考虑只写一个动态壁纸。这将适合更多的舒适进入系统：你可以改变你呈现时，你想要什么，当用户选择了一个不同的墙纸，因为你的生活壁纸将被停止很显然

To be honest, if you are making a wallpaper that is going to change, you really should consider just writing a live wallpaper. This will fit much more comfortably into the system: you can change what you are showing whenever you want, and it is clear when the user has selected a different wallpaper because your live wallpaper will be stopped.

另外你必须非常小心使用ACTION_WALLPAPER_CHANGED的，因为它可以让你与其他应用程序交互不好。下面是这将出现下一个API的文档：

Also you need to be extremely careful about the use of ACTION_WALLPAPER_CHANGED, because it can get you into bad interactions with other applications. Here is the documentation for it that will appear in the next API:

/**
 * Broadcast Action:  The current system wallpaper has changed.  See
 * {@link android.app.WallpaperManager} for retrieving the new wallpaper.
 * This should <em>only</em> be used to determine when the wallpaper
 * has changed to show the new wallpaper to the user.  You should certainly
 * never, in response to this, change the wallpaper or other attributes of
 * it such as the suggested size.  That would be crazy, right?  You'd cause
 * all kinds of loops, especially if other apps are doing similar things,
 * right?  Of course.  So please don't do this.
 *
 * @deprecated Modern applications should use
 * {@link android.view.WindowManager.LayoutParams#FLAG_SHOW_WALLPAPER
 * WindowManager.LayoutParams.FLAG_SHOW_WALLPAPER} to have the wallpaper
 * shown behind their UI, rather than watching for this broadcast and
 * rendering the wallpaper on their own.
