1. Read the resource files in the jar package through the AssetManager class

The AssetManager class provides an interface for reading files and xml files.

Note: The restriction is that the file to be read must be placed in the Assets folder.

 

The following is an example of reading resources.

Public static Drawable getAssertDrawable (Context context, String fileName) {try {InputStream inStream = context. getAssets (). open (fileName); return new BitmapDrawable (BitmapFactory. decodeStream (inStream);} catch (IOException e) {Log. e (LOG_TAG, "Assert" + fileName + "does not exist");} return null ;}

Use the ClassLoader class to read resource files

The classLoader class provides interfaces for reading resource paths and resources (in stream form.

The difference between the classLoader class and the AssetManager class is that the classLoader class can also read Resources in the res folder.

 

 

The following is a small example of ClassLoader reading resources.

　　BufferedImage image=ImageIO.read(ClassLoader.getSystemResourceAsStream(“/res/drawable/icon.png”));
