Layout UIDs and layout names are used in Android development to identify a layout. Layout UIDs are unique identifiers of the layouts while layout names are the human readable name of the layout.
Layout UIDs: Layout UIDs (UID) is a unique identifier for each view in an XML file. It is used to uniquely identify views within a single XML file. This allows you to refer to views by their ids instead of their ids and names, which can be long and difficult to remember.
Layout Names: Layout name is the human readable name of a view in an XML file. It can be any text string that describes what the view looks like or what it does when displayed on screen.
