Use the addTextChangedListener method on your EditText and make your class implement or define an inner class implementing the TextWatcher class:

textMessage = (EditText)findViewById(R.id.textMessage);
    textMessage.addTextChangedListener(new TextWatcher(){
        public void afterTextChanged(Editable s) {

}
        public void beforeTextChanged(CharSequence s, int start, int count, int after){}
        public void onTextChanged(CharSequence s, int start, int before, int count){}
    });
