Save timestamp in shared preferences when a button is clicked

Question

How do I save a timestamp in shared preferences for the moment when a button is clicked?

button.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
               //some logic...
            }
        });

Here is a piece of code

Long timestamp = System.getCurrentTimeInMillis()
SharedPreferences prefs = getApplicationContext().getSharedPreferences("preferences", Context.MODE_PRIVATE);
prefs.edit().putLong("time", timestamp).commit();

  in this way you can save current time in SharedPreferences 

  SharedPreferences preferences;
  button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {

   preferences = getSharedPreferences("pref_namae",MODE_PRIVATE);
    SharedPreferences.Editor editor = preferences.edit();
    editor.putLong("TimeStamp",System.currentTimeMillis());
    editor.apply();
        }
    });

to get value from prefercance use this code.

long timeStamp = preferences.getLong("TimeStamp",0);

Just like this:

SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context);
sharedPreferences.edit()
            .putLong("YourKey", timestamp)
            .apply();

You can use SimpleDateFormat to save time in your required timestamp.

SimpleDateFormat simpleDateFormat=new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ", Locale.US);
    Date date=new Date(System.currentTimeMillis());
    String formatDate=simpleDateFormat.format(date);

You can refer here for other date formats. And use SharedPreference to save it.
