    You are looking for TextWatcher:

        youredittext.addTextChangedListener(new TextWatcher()
        {
            @Override
            public void afterTextChanged(Editable mEdit) 
            {
                text = mEdit.toString();
            }
    
            public void beforeTextChanged(CharSequence s, int start, int count, int after){}
    
            public void onTextChanged(CharSequence s, int start, int before, int count){}
        });
