[android-beginners] Re: getting length of an EditText while entering text
One way would be to subclass the EditText class... You would then have access to onTextChanged and could do whatever you want with it.

I see that the TextView has a protected method onTextChanged, but how can I make the activity get informed about a change, so I can update the text? href to that method: http://developer.android.com/reference/android/widget/TextView.html#onTextChanged(java.lang.CharSequencehttp://developer.android.com/reference/android/widget/TextView.html#onTextChanged%28java.lang.CharSequence , int, int, int) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

Thanks Justin, That sounds like a big overhead :-( for something quite simple. I hope there is somehow a simpler way available...

And indeed there is... My last post was without referencing the docs. However there is this: addTextChangedListener(TextWatcher watcher) Hope that helps.
