I guess my title is not clear enough. Okay, let says in this way.
1- I have a spinner that acts as Filter. By default if user clicks on spinner, drop down list appears and displays my values.
2- When user selects item_1 then fragmentDialog appears and displays my lists. User is able to select an item and my fragment/activity will respond accordingly.
3- Now, if user click on spinner and selects item_1 again, drop down list closes and nothing happens. I want drop down list displays fragmentDialog again and let user to select another item.
It seems when user selects an item from drop-down list then by selecting same item onItemSelected() callback never invoke unless user click on another item.
Hope I could explain what is my problem. Thanks.
