这是我的应用程序，我想一些图片保存到我的SD卡。为此，我需要创建一个文件夹。

From my application, I want to store some images into my SD card. For that I need to create a one folder.

目前首次夹将创建，但它会检查该文件夹是否是present或不是之后。我该怎么办呢？

At the first time folder will create but after it checks whether that folder is present or not. How can I do it?

推荐答案

低于code将创建一个目录，如果它不存在

below code will create a directory if it does not exist

   File direct = new File(Environment.getExternalStorageDirectory() + "/New Folder");

   if(!direct.exists())
    {
        if(direct.mkdir()) 
          {
           //directory is created;
          }

    }
