Various Android APIs are designed to +operate on the resource IDs instead of dealing with images, strings or binary blobs +directly. + +For example, a sample Android app that contains a user interface layout (main.axml), +an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png) +would keep its resources in the "Resources" directory of the application: + +Resources/ + drawable/ + icon.png + + layout/ + main.axml + + values/ + strings.xml + +In order to get the build system to recognize Android resources, set the build action to +"AndroidResource". The native Android APIs do not operate directly with filenames, but +instead operate on resource IDs. When you compile an Android application that uses resources, +the build system will package the resources for distribution and generate a class called "R" +(this is an Android convention) that contains the tokens for each one of the resources +included. For example, for the above Resources layout, this is what the R class would expose: + +public class R { + public class drawable { + public const int icon = 0x123; + } + + public class layout { + public const int main = 0x456; + } + + public class strings { + public const int first_string = 0xabc; + public const int second_string = 0xbcd; + } +} + +You would then use R.drawable.icon to reference the drawable/icon.png file, or R.layout.main +to reference the layout/main.axml file, or R.strings.first_string to reference the first +string in the dictionary file values/strings.xml. |
