I have a spinner that is populated by an sqlite db. However when the app is
first used and the cursor is empty, I want the spinner to offer an option to
add a new item. In fact I would like this option to always be available at
the end of the spinner list, but at this point I will settle for just when
the cursor is empty. The below code shows what I have tried. Although the
OnItemSelected method is called when the spinner is created. Therefore
since the only item is the "Add Item" item, NewItem gets called on creation
instead of when the user selects it. This would be fine because I could
just ignore the onItemSelected call on creation, but because the item is
selected, when the user then tries to select "Add Item", the
OnItemSelectedListener ignores the selection (which is wrong by the way, it
should be up to the code to do the ignoring not the widget, but that is
another topic).
if (_spinnerAdp.isEmpty())
{
// GetAddItemAdapter just returns an ArrayAdapter of 1 string
_spinnerAdp.setAdapter(GetAddItemAdapter(this));
_spinnerAdp.setSelection(-1);
_spinnerAdp.setOnItemSelectedListener(new OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> arg0, View arg1, int position,
long id)
{
NewItem()
}
public void onNothingSelected(AdapterView<?> arg0)
{
//when does this happen?
}
});
}
Does anyone have a method to do this? I have seen "add item" selections in
spinners before in other UI Frameworks and think it is intuitive way to get
this done. I am not stuck on a spinner though if there is another widget
that is easier to get this same thing done...
Thanks
