Furthermore, I checked it with a very simple example. ListActivity,
with one list. It's OK with ArrayAdapter, but it does not work with
SimpleCursorAdapter. The activity contains only the onCreate method,
and the corresponding imports. Someone could verify this?
WORKING EXAMPLE:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_activty);
mListView = getListView();
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_multiple_choice, COUNTRIES));
mListView.setItemsCanFocus(false);
mListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}
DOESN'T WORK:
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_activty);
FinTracDatabase database = mDatabaseProvider.get();
Cursor cursor = database.getTransactionCursor(false);
mListView = getListView();
setListAdapter(new SimpleCursorAdapter(
this,
android.R.layout.simple_list_item_multiple_choice,
cursor,
new String[] { Transactions.TITLE },
new int[] { android.R.id.text1 },
0));
mListView.setItemsCanFocus(false);
mListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}
