Displaying Error if no item from a spinner is selected

Updated 18 December 2016


Hello Everyone,
This blog is quite easy to understand and implement.
We all use spinner to display a list of selectable options and make our app interface more interactive .
In order to make app UI more interactive, we all try to set and point the error exactly at the view which is left empty. Let’s see how to do this on a spinner.


Concept : 
A Spinner in android is actually a collection of textviews that are listed according to the number of entries in the list.
All you need to do is, to check if the spinner is empty and then select the default text view and set error message on that text view.

How to do this :

  1. Check if spinner is empty.
  2. Get the default selected view.
  3. Request Focus for the same view.
  4. Set some error message to be displayed.
  5. You can also perform a click on the spinner so that the spinner list is displayed. (additional option).


calling error method if spinner is empty :

And it is done .
Check it out and I believe this makes UI better.

Keep coding and Keep Sahring.
