我希望我的行为出现在活动列表（画廊。动态壁纸等）时，尽量选择从主屏幕壁纸，你看到的。

I want my activity to appear in the list of activities (gallery. live wallpapers, etc) that you see when you try to choose a wallpaper from the home screen.

林假设这是有意向做，但不能似乎找到一个工作。最近的一个我能找到的：

Im assuming this is done with intents but cant seem to find one that works. The closest one I can find is:

<action android:name="android.intent.action.ACTION_SET_WALLPAPER>

但是，这并不工作，似乎是用别的东西。

but that doesn't work and seems to be used for something else.

推荐答案

这应该是意图过滤器，你想要的：

This should be the intent-filter you want:

<intent-filter>
    <action android:name="android.intent.action.SET_WALLPAPER" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

定义如下：http://developer.android.com/reference/android/content/Intent.html#ACTION_SET_WALLPAPER

（默认类别是意图标准的语法。）

(The DEFAULT category is a standard syntax for intents.)
