A resource in Android is a file (like a
music file) or a value (like the title of a dialog box) that is bound to an executable
application. These files and values are bound to the executable in such a way that you
can change them without recompiling the application.
String Resources
Android allows you to define strings in one or more XML resource files.
These XML files containing string-resource definitions reside in the /res/values subdirectory.
例:
<?
xml version="1.0" encoding="utf-8"
?>
< resources >
< string name ="hello" >hello </ string >
< string name ="app_name" >hello appname </ string >
</ resources >
< resources >
< string name ="hello" >hello </ string >
< string name ="app_name" >hello appname </ string >
</ resources >
Layout Resources
In Android, the view for a screen is often loaded from an XML file as a resource. These
XML files are called layout resources.A layout resource is a key resource used in
Android UI programming.
