Wallpaper describes how to use a style to set the system wallpaper as the background of the current activity. This is the definition of wallpaperactivity in androidmanifest. xml: <Activity Android: Name = ". App. wallpaperactivity" Android: Label = "@ string/activity_wallpaper" Android: theme = "@ style/theme. Wallpaper"> <Intent-filter> <Action Android: Name = "android. Intent. Action. Main"/> <Category Android: Name = "android. Intent. Category. sample_code"/> </Intent-filter> </Activity> @ Style/theme. wallpaper is defined as follows: Inherit the Android: style/theme. wallpaper system and set the foreground color to white (the text color here) <! -A theme that has a wallpaper background. Here we explicitly specify That this theme is to inherit from the system's wallpaper theme, Which sets up various attributes correctly.-> <Style name = "theme. Wallpaper" parent = "Android: style/theme. Wallpaper"> <Item name = "Android: colorforeground"> # fff </item> </Style>
