You can start a DialogFragment with a EditText (How to take text input with DialogFragment in Android?) and you can handle this dialog with you list item click.

Click Item -> Open Dialog Asking Password -> Return the password from the edit text -> Do Something you want.

if you want show a edit text in the listview item, you can set the item as view.invisibly and set the visibility with the event click.
