다이얼로그안에 토글 스위치... 질문입니다.

Question

Context mContext2 = getApplicationContext();
    LayoutInflater inflater2 = (LayoutInflater) mContext2
      .getSystemService(LAYOUT_INFLATER_SERVICE);
    View layout2 = inflater2.inflate(
      R.layout.tab_host_notification_log, null);
    
    final TextView tvStateofToggleButton;
    tvStateofToggleButton = (TextView) findViewById(R.id.tvstate);
    tvStateofToggleButton.setText("OFF");

    AlertDialog.Builder ntDialog = new AlertDialog.Builder(
      Tab_host_Setting.this);
    ntDialog.setTitle("알림 변경");
    ntDialog.setView(layout2);

    ntDialog.setPositiveButton("확인",
      new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog,
         int which) {

        ToggleButton tButton = (ToggleButton) findViewById(R.id.toggleButton1);
        tButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {

         @Override
         public void onCheckedChanged(
           CompoundButton buttonView,
           boolean isChecked) {

          if (isChecked) {
           tvStateofToggleButton.setText("ON");
           Log.e("토글", "ON");
          } else {
           tvStateofToggleButton
             .setText("OFF");
           Log.e("토글", "OFF");
          }

         }
        });
       }
      });

java.lang.NullPointerException 이 값이 왜 떨어기는것인가요 ㅠ.ㅠ 다이얼로그안에 토글 스위치 사용이 불가능 한것인지.. 머리속에서는 가능 할듯 한데.. 왜 널값이 떨어지는지를 모르겟어요 ㅠ.ㅠ

ntDialog.setPositiveButton("확인",
      new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog,
         int which) {

       }

      });

    ToggleButton tButton = (ToggleButton) layout2
      .findViewById(R.id.toggleButton1);
    final TextView tvStateofToggleButton;
    tvStateofToggleButton = (TextView) layout2
      .findViewById(R.id.tvstate);
    tvStateofToggleButton.setText("OFF");
    Log.e("토글", "1");
    tButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {

     @Override
     public void onCheckedChanged(CompoundButton buttonView,
       boolean isChecked) {
      Log.e("토글", "2");
      if (isChecked) {
       tvStateofToggleButton.setText("ON");
       Log.e("토글", "ON");
      } else {
       tvStateofToggleButton.setText("OFF");
       Log.e("토글", "OFF");
      }

     }
    });

    AlertDialog ntlog = ntDialog.create();
    ntlog.show();
