如果你不想改为全透明，只想调节透明度
1.packages\apps\Launcher3\res\values\styles.xml
主题一：
<style name="BaseLauncherThemeWithCustomAttrs" parent="@style/BaseLauncherTheme">
<item name="allAppsScrimColor">#CCFFFFFF</item>
主题二：
<style name="LauncherThemeDark" parent="@style/LauncherTheme">
<item name="allAppsScrimColor">#7A212121</item>
其中#号后面的两位数字“CC”和“7A”为透明度（00～FF），可以根据需求修改，全透明为00
- packages\apps\Launcher3\res\values\congfig.xml
<integer name="extracted_color_gradient_alpha">153</integer>
取值范围为0～255
具体修改原因这里不多做介绍，“Read The Fucking Source Code!”
主菜单全透明比较完善的方案基于原生Launcher3，需要的拿走
