Images, layout descriptions, binary blobs and string dictionaries can be included |
|||
in your application as resource files. 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.xml), |
|||
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-hdpi/ |
|||
icon.png |
|||
|
|||
drawable-ldpi/ |
|||
icon.png |
|||
|
|||
drawable-mdpi/ |
|||
icon.png |
|||
|
|||
layout/ |
|||
main.xml |
|||
|
|||
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 |
|||
"Resource" that contains the tokens for each one of the resources included. For example, |
|||
for the above Resources layout, this is what the Resource class would expose: |
|||
|
|||
public class Resource { |
|||
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 Resource.layout.main |
|||
to reference the layout/main.xml file, or Resource.strings.first_string to reference the first |
|||
string in the dictionary file values/strings.xml. |
