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);
}
}
}
