Question

You don't need KeyListener. Use TextWatcher for it:

((EditText)findViewById(R.id.your_edit_text)).addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {
            if(s != null && s.length() > 0 && s.charAt(s.length() - 1) == ' '){
                //dp something
            }
        }
    });
