TextWatcher не работает, что не так

Реализация TextWatcher в методе onCreate не работает, я пробовал вводить текст с использованием виртуальной клавиатуры и присутствующей аппаратной клавиатуры, также пробовал код на эмуляторе и реальном устройстве. вроде ничего не работает.

я даже переименовал EditTexts в макете и очистил проект, перестроил его, без надежды

любая идея?

вот код

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.remarks);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    Intent i = getIntent();
    Current_Language = i.getStringExtra("Lang");
    Q1Rate = i.getFloatExtra("Q1Rate", 0f);
    Q2Rate = i.getFloatExtra("Q2Rate", 0f);
    Q3Rate = i.getFloatExtra("Q3Rate", 0f);
    Q4Rate = i.getFloatExtra("Q4Rate", 0f);
    Q5Rate = i.getFloatExtra("Q5Rate", 0f);
    LoadSettings();
    NextBtnState();
    final EditText edt_PhoneNo     = (EditText) findViewById(R.id.edt_Remarks_PhoneNo);
    final EditText edt_Suggestions = (EditText) findViewById(R.id.edt_Remarks_Suggestion);
    edt_Suggestions.addTextChangedListener(new TextWatcher() {
        public void onTextChanged(CharSequence s, int start, int before, int count) {
        }
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }
        public void afterTextChanged(Editable s) {
            ShowToast("I Am Here Firas");
            resetTimeout();
        }
    });
    edt_PhoneNo.addTextChangedListener(new TextWatcher() {
        public void onTextChanged(CharSequence s, int start, int before, int count) {
        }
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }
        public void afterTextChanged(Editable s) {
            ShowToast("I Am Here Firas");
            resetTimeout();
        }
    });
}

вот мой ShowToast

public void ShowToast (String Msg) {
    Context context = getApplicationContext();
    CharSequence text = Msg;
    int duration = Toast.LENGTH_LONG;
    Toast toast = Toast.makeText(context, text, duration);
    toast.setGravity(Gravity.CENTER|Gravity.CENTER, 0, 0);
    toast.show();
}

а вот макет
