I am having some trouble displaying the files currently modified date.

public class MyAdapter extends ArrayAdapter<String> {
String dir = "/FileDirectory/";
File file = new File(Environment.getExternalStorageDirectory() + dir);
private final Activity context;
Date lastModified = new Date(file.lastModified()); 
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");  
String formattedDateString = formatter.format(lastModified); 
private String dateFormat = "dd/MM/yyyy HH:mm:ss";
static class ViewHolder {
    public TextView text;
public MyAdapter(Activity context, String[] date) {
    super(context, R.layout.row, date);
    this.context = context;
    formatter = new SimpleDateFormat(dateFormat);
@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View rowView = convertView;
    if (rowView == null) {
        LayoutInflater inflater = context.getLayoutInflater();
        rowView = inflater.inflate(R.layout.row, null);
        ViewHolder viewHolder = new ViewHolder();
        viewHolder.text = (TextView) rowView.findViewById(R.id.FilePath);
        rowView.setTag(viewHolder);
    ViewHolder holder = (ViewHolder) rowView.getTag();
    String s = formattedDateString;
    holder.text.setText(s);
        return rowView;
As of now it just displays the last modified date of the directory on all files.  Any help would be greatly appreciated!
In your question, you are pointing a Directory, not a File.
File file = new File(Environment.getExternalStorageDirectory() + dir);
private final Activity context;
Date lastModified = new Date(file.lastModified()); 
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");  
String formattedDateString = formatter.format(lastModified);
The idea is to get a Directory and iterate searching for the Last modified date of all files. The following question may help:
How to get only 10 last modified files from directory using Java?
EDIT 1:
My Tricky Solution: 
File images = new File("YourDirectoryPath");
long[] fileModifieDate = new long[images.listFiles().length];
int i=0;
        File[] imagelist = images.listFiles(new FilenameFilter()
            public boolean accept(File dir, String name)
                File file = new File(dir, name);
                fileModifieDate[i++] = file.lastModified();
                return true;
// Here, max is the last modified date for this directory 
// Here, Long array **fileModifieDate** will give modified time of all files, which you can also access from Files array
// if you want the last modified file in the directory you can do this:
        File[] maxModifiedDate = images.listFiles(new FilenameFilter()
            public boolean accept(File dir, String name)
                File file = new File(dir, name);
                return file.lastModified() == max;
// Now **maxModifiedDate** File array will have only one File, which will have max modified date.
EDIT 2:
For your case, this would be helpful:
public class MyAdapter extends ArrayAdapter<String> {
String dir = "/FileDirectory/";
File myFolder= new File(Environment.getExternalStorageDirectory() + dir);
if(myFolder.exists()){
    File[] filelist = myFolder.listFiles(new FilenameFilter()
        public boolean accept(File dir, String name)
            return true;
// Now you have a filelist array of Files. If you want lastModified data, you can fetch from each individual file as you were doing previously:
  private final Activity context;
    Date lastModified = new Date(file.lastModified()); 
    SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");  
    String formattedDateString = formatter.format(lastModified); 
    private String dateFormat = "dd/MM/yyyy HH:mm:ss";
                Thanks for your response.  Well what I am wanting is to display when each of the files was modified in a list.  It is not a big deal to me if they are sorted correctly.

                @user2250122 : i think from List of files you can get the lastModified date of all files see updated answer which clarifies and list all modified date for all files in directory

    File file = new File("c:\\test\\myfile.txt");
    SimpleDateFormat sdf = new SimpleDateFormat("MM-dd-yyyy HH:mm:ss");
    System.out.println("Modified Date :- " + sdf.format(file.lastModified()));
File file = new File(Environment.getExternalStorageDirectory() + dir);
Points to directory, not a file.
If you need modified date of each file separately in a directory, just use walkfiletree.
Check this.
I tried the answer of Anonymous Mohit, but it only checks the file size of items inside the folder. But what if there are many subfolders? Here's how I did it.
public static long lastModifiedDate;
public static long getLastModified(String path) {
    File directory = new File(path);
    File[] files = directory.listFiles();
    if(GlobalValues.DEBUG) Log.i(TAG, "Get last modified date: " + path);
    if (files.length == 0) return directory.lastModified();
    else {
        for(File filesInFolder: files) {
            if(filesInFolder.isDirectory()) {
                getLastModified(filesInFolder.getAbsolutePath());
            } else {
                if(lastModifiedDate == 0) {
                    lastModifiedDate = filesInFolder.lastModified();
                } else{
                    if(filesInFolder.lastModified() >= lastModifiedDate){
                        lastModifiedDate = filesInFolder.lastModified();
        return lastModifiedDate;
