können Sie diese Methode verwenden, eine andere Bitmap von Ihrem erstellen Offset

/** 
* Returns an immutable bitmap from the specified subset of the source 
* bitmap. The new bitmap may be the same object as source, or a copy may 
* have been made. It is initialized with the same density as the original 
* bitmap. 
* 
* @param source The bitmap we are subsetting 
* @param x  The x coordinate of the first pixel in source 
* @param y  The y coordinate of the first pixel in source 
* @param width The number of pixels in each row 
* @param height The number of rows 
* @return A copy of a subset of the source bitmap or the source bitmap itself. 
* @throws IllegalArgumentException if the x, y, width, height values are 
*   outside of the dimensions of the source bitmap, or width is <= 0, 
*   or height is <= 0

public static Bitmap createBitmap(Bitmap source, int x, int y, int width, int height) { 
    return createBitmap(source, x, y, width, height, null, false); 
} 

Eine weitere Option ist eine benutzerdefinierte Image erstellen, dann außer Kraft setzen onDraw() Methode Bitmap

Nutzung auf Canvas von Ihrem Offsets zu ziehen Diese Methode Canvas Klasse

public void drawBitmap(@NonNull Bitmap bitmap, float left, float top, @Nullable Paint paint) { }
