锁屏、桌面、桌面万象小组件联动<globalPersist>

功能概述

通过在锁屏、桌面和桌面万象小组件的变量声明脚本中，同时给变量的globalPersist属性设置为true，可以实现锁屏、锁屏和桌面万象小组件使用同一个变量的值。

globalPersist是锁屏、桌面和桌面万象小组件变量同步的桥梁，可以将锁屏上变量的变化传递给桌面和桌面万象小组件，实现更多的创意主题。

应用场景

• 在锁屏中双击切换壁纸、桌面和桌面万象小组件的背景图片同步变化。

XML规范

 <Var name="cartoon" expression="1" type="number" globalPersist="true"/>

参数说明

应用示例

示例一：锁屏上设置红、白、黑3张壁纸，双击切换壁纸颜色。在锁屏上切换壁纸颜色后，将变化同步给桌面和桌面万象小组件，桌面和桌面万象小组件的壁纸颜色同步变化。

• 桌面脚本

<CommonWallpaper displayDesktop="true" frameRate="60" id="201801194068" screenWidth="1080" version="1">

• 桌面万象小组件脚本

<Widget version="1" frameRate="30" displayDesktop="true" screenWidth="940" screenHeight="940">
	<Group x="0" y="0" visibility="true">
		<Image x="0" y="0" src="clock_1.png" visibility="eq(#bg_id,0)"/>
		<Image x="0" y="0" src="clock_2.png" visibility="eq(#bg_id,1)"/>

	</Group>

	<Button x="0" y="0" w="940" h="940">
		<Trigger action="click">
			<IntentCommand action="android.intent.action.MAIN" package="com.android.deskclock" class="com.android.deskclock.AlarmsMainActivity"/>
		</Trigger>
	</Button>
</Widget>

示例二：锁屏与桌面的背景图片同步变化

为变量cartoon声明globalPersist="true"：即锁屏和桌面中cartoon的值将同步变化。cartoon作为image标签的资源id控制参数，可以控制图片资源变化。双击屏幕可以改变cartoon的值，以显示对应的图片资源，同时锁屏和桌面的图片会同步变化。注意：需要给锁屏和桌面设置相同的或相关联的图片资源。
