Field Details

LOOP_FOREVER

public static final int LOOP_FOREVER

A constant indicating that an animated drawable should loop continuously.

• Constant Field Values

LOOP_INTRINSIC

public static final int LOOP_INTRINSIC

A constant indicating that an animated drawable should loop for its default number of times. For animated GIFs, this constant indicates the GIF should use the netscape loop count if present.
