Question

Mi main activity is a TabActivity that launches an intent TabGroup activity, this tabGroup starts a child activity, this child activity is a Listview with several options.
And now, if you select some option from the listview and change the device orientation, I lose focus from the current activity because the oncreate() from the TabGroup is called, there is any way to prevent this?
Many thanks for the help!.

Answer 1

The activity gets shut down and restarted on orientation change.

use onSaveInstanceState(Bundle) to store the selected option and restore that selection in onCreate(Bundle).

i.e.

onSaveInstanceState(Bundle bundle) {
bundle.putInt("selected", listView.getSelectedItemPosition());
}


onCreate(Bundle bundle) {
if (bundle.containsKey("selected")) {
listView.setSelection(bundle.getInt("selected"));
}
