java - Android: Directories & sub-directory listing continuous Activity issue -

I am trying to create a directory list that shows a list of folder names. If the user clicks on the directory name and if that directory has sub-directories then a new activity will be asked to list all the sub-directories. And this process will continue. I have made the first page list, but now because it is a continuous looping process, what approach should I use whether this parental activity can call itself or do I use the initial activity for the result or viewflipper or something else Please suggest please.

edit [code added:]

main activity class

  public class main activity list extension provides OnClickListener {button ended, canceled Select, select all; See list view list; ArrayAdapter & LT; Directory & gt; Adapter; & Lt; Directory & gt; List; Hashmap & lt; String, Boolean & gt; CheckedMap; Override public null on @reate (bundle saved instainstate) {super.naught (savedinstenstate); Try {setContentView (R.layout.main); Did = (button) findViewById (R.id.bDone); Cancel = (button) FindById (R.id.bCancel); Select all = (buttons) ViewById (R.id.bSelAll); Done.setOnClickListener (this); Cancel.setOnClickListener (this); New AsyncHandler (this). Execute (); If (list! = Null) {checkedMap = new hashMap & lt; String, Boolean & gt; (); Iterator & LT; Directory & gt; I = list.iterator (); While (i.hasNext ()) {directory D = (directory) i.next (); Checked map.put (d.getName (), d.isSelected ()); }}} Hold (exception e) {toast. Make Text (it, E.Stosting (), Toast. LNNGHHORT). Show (); }} @ Override Protected click on ListItem (ListView L, VV, Int Status, Long ID) {// Super.

 Custom adapter  
  public class element adapter ArrayAdapter {Private context reference; Private list & lt; directory & gt; list; Public element adapter , List & lt; directory & gt; list) {super (c, r.
