You may find this project useful. Simply use the code to create pattern password

Intent intent = new Intent(context, LockPatternActivity.class); intent.putExtra(LockPatternActivity._Mode, LockPatternActivity.LPMode.CreatePattern); startActivityForResult(intent, _ReqCreatePattern);

and in onActivityResult you get your password.
