你可以试试这个:

WallpaperManager wallpaperManager = WallpaperManager.getInstance(this);
Drawable drawable = getResources().getDrawable(R.drawable.newimage);
Bitmap wallpaper_source = ((BitmapDrawable) drawable).getBitmap();           
try {
    int w = wallpaperManager.getDesiredMinimumWidth();
    int h = wallpaperManager.getDesiredMinimumHeight();
    int x = (w-wallpaper_source.getWidth())/2;
    int y = (h-wallpaper_source.getHeight())/2;
    Bitmap wallpaper = Bitmap.createBitmap(w, h, Config.ARGB_8888);
    Canvas c = new Canvas(wallpaper);
    c.drawBitmap(wallpaper_source, x,y, null);
    wallpaperManager.setBitmap(wallpaper);
} 
catch (IOException e) 
{
    e.printStackTrace();
}
