Hi,
The basic list that I want to view is working.
In my first list activity(ListDemoActivity), I choosed some element,
which triggers another list A activity. If I go back (on pressing
"BACK" key), the state of ListDemoActivity screen is preserved. Now
If I select the same element again, I expect the state of A activity
to be preserved aswell, but its not happening.
Below is the code snippet, Can you please suggest me what I need to do?
public class ListDemoActivity extends ListActivity {
String[] firstPage = {"a", "b", "c", "d", "e"};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
firstPage));
}
public void onListItemClick(ListView parent, View v,
int position, long id)
{
String txt = firstPage[position];
if ((txt == "a") ||
(txt == "b"))
{
Intent startActivity = new Intent(this, Activity_A.class);
startActivity.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startActivity);
}
else
{
Intent startActivity = new Intent(this, Activity_B.class);
startActivity.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startActivity);
}
}
}

correct?
Yes
Also, how to store parent list in the stack? so that on pressing "escape"
key, I can navigate backwards.
Android does this automatically, and I assume you mean the 'back'
key. Each new activity is launched ontop of the older ones allowing
you to navigate backwards down the stack.
