How can I format an EditText to follow the " dd/mm/yyyy " format the same way that we can format using a TextWatcher to mask the user input to look like "0.05€". I'm not talking about limiting the characters, or validating a date, just masking to the previous format. Juan Cortés I wrote this TextWatcher for a project, hopefully it will be helpful to someone. Note that it does not validate the date entered by the user, and you should handle that when the focus changes, since the user may not have finished entering the date. Update 25/06 Made it a wiki to see if we reach a better final code.

android edittext onchange listener

I know a little bit about TextWatcher but that fires on every character you enter. I want a listener that fires whenever the user finishes editing. Is it possible? Also in TextWatcher I get an instance of Editable but I need an instance of EditText . How do I get that? EDIT : the second question is more important. Please answer that.
