1. 选择一个图片文件夹，将需要用到的壁纸放在该文件下

2. 在该文件夹下运行如下脚本：

   import glob, os
   import shutil
   import time
   
   
   curdir = os.getcwd()
   os.chdir(curdir)
   currentFilelist = glob.glob('*.*')
   currentImageFiles = glob.glob('*.jpg')
   
   currentTime = time.localtime()
   length = len(currentImageFiles)
   
   for i in currentFilelist:
    if i == 'backgroundslide.xml':
     os.remove(i)
   
   f = file('backgroundslide.xml', 'w')
   
   f.write('\n')
   f.write('\t\n')
   f.write('\t\t' + str(currentTime.tm_year) + '\n')
   f.write('\t\t' + str(currentTime.tm_mon) + '\n')
   f.write('\t\t' + str(currentTime.tm_mday) + '\n')
   f.write('\t\t' + str(currentTime.tm_hour) + '\n')
   f.write('\t\t' + str(currentTime.tm_min) + '\n')
   f.write('\t\t' + str(currentTime.tm_sec) + '\n')
   f.write('\t\n')
   f.write('\n')
   
   for i in currentImageFiles:
    length = length - 1
    print length
    #print curdir
    #print currentImageFiles[1]
    f.write('\t\n')
    f.write('\t\t595.0\n')
    f.write('\t\t' + curdir + '/' + currentImageFiles[length] +'\n')
    f.write('\t\n')
    f.write('\t\n')
    f.write('\t\t5.0\n')
    f.write('\t\t' + curdir + '/' + currentImageFiles[length] + '\n')
    if length >= 1:
     f.write('\t\t' + curdir + '/' + currentImageFiles[length-1] + '\n')
    if length <1:
     f.write('\t\t' + curdir + '/' + currentImageFiles[len(currentImageFiles)-1] + '\n')
    f.write('\t\n')
   
   f.write('\n')
   f.close()

    3. 将生成的background.xml加入桌面背景选择中
