Various Android APIs are designed to 3 | operate on the resource IDs instead of dealing with images, strings or binary blobs 4 | directly. 5 | 6 | For example, a sample Android app that contains a user interface layout (main.xml), 7 | an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png) 8 | would keep its resources in the "Resources" directory of the application: 9 | 10 | Resources/ 11 | drawable-hdpi/ 12 | icon.png 13 | 14 | drawable-ldpi/ 15 | icon.png 16 | 17 | drawable-mdpi/ 18 | icon.png 19 | 20 | layout/ 21 | main.xml 22 | 23 | values/ 24 | strings.xml 25 | 26 | In order to get the build system to recognize Android resources, set the build action to 27 | "AndroidResource". The native Android APIs do not operate directly with filenames, but 28 | instead operate on resource IDs. When you compile an Android application that uses resources, 29 | the build system will package the resources for distribution and generate a class called 30 | "Resource" that contains the tokens for each one of the resources included. For example, 31 | for the above Resources layout, this is what the Resource class would expose: 32 | 33 | public class Resource { 34 | public class drawable { 35 | public const int icon = 0x123; 36 | } 37 | 38 | public class layout { 39 | public const int main = 0x456; 40 | } 41 | 42 | public class strings { 43 | public const int first_string = 0xabc; 44 | public const int second_string = 0xbcd; 45 | } 46 | } 47 | 48 | You would then use R.drawable.icon to reference the drawable/icon.png file, or Resource.layout.main 49 | to reference the layout/main.xml file, or Resource.strings.first_string to reference the first 50 | string in the dictionary file values/strings.xml. 51 | --------------------------------------------------------------------------------
