Want to automatically calculate age and date of birth...

Hi... I want to do a task in android... If i enter the date of birth in a edittext then age should be calculated and if i enter the age in edittext then birth year should be calculated automatically.. This must be done without using buttons... How to do.. Help me.

Add a Listener process for the text box that checks the content. If it looks like a date of birth then calculate the age. If it looks like an age then calculate the date of birth. See http://developer.android.com/guide/topics/ui/controls/text.html[^] for more details.

This sounds like a bad UI in the making. For example, if you wanted to enter the birth year 2003 and got the 20 entered, how would your code know that it was part of the birth year and not the age? Listening for each letter typed and trying to figure out the user's intent is not always possible and leaves room for misinterpretation.

Put your logic in afterTextChange with help of onTextChaneListener.
