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);
