how to avoid editText change using textWatcher?

Question

I have an editText that i want to control in length.

how can i avoid the user from entering a character which will lead the text to be longer than X ?

I have thought to use beforeTextChanged(CharSequence s, int start, int count, int after) {

but then i'm not sure how to skip adding the character if i want.

The length is determined dynamically - getting this from the server side on activity start

Well, if you need to stop the user from entering a text longer than x, simply put android:maxLength="x" as an attribute for your EditText.

Or,

mEditText.setFilters( new InputFilter[] { new InputFilter.LengthFilter(<length>) } );

so you can code into .java file, make string object and get the length of string into your edittext using this property in dynamically way. – jack May 05 '14 at 05:20
