Android programming to achieve the method of sorting files in folders

This article describes an example of Android programming to achieve the method of sorting files in folders. To share with you for your reference, as follows:

private int mFileSize = 0;
private List<String> mPathString = new ArrayList<String>();
private boolean sortFolder(String path) {
    if (path == null || StringUtil.isEmpty(path))
      return false;
    File[] fileList = null;
    File file = new File(path);
    if (file.exists() == false){
      file.mkdir();
    }
    if (!file.exists() || (file.isDirectory() && (file.listFiles().length == 0))) {
      return true;
    } else {
      fileList = file.listFiles();
      mFileSize = file.listFiles().length;
  mPathString.clear();
      if(mFileSize > 0) {
        for(int i = 0;i < mFileSize;i++) {
          mPathString.add(fileList[i].getAbsolutePath());
        }
        Collections.sort(mPathString);
      }
      return false;
    }
}

PS: Parameter path is the path to the folder
For descending sort

Collections.reverse(mPathString);
