日付時刻選択ツールの値を取得する方法は？

Question

アラートダイアログからの日付と日付を設定する必要があります。私はDate Time Pickerの値を得るために新しいXMLレイアウトを作成しました。しかし、私はそれぞれの値を別々に得る方法を知らない。Textview。

MainFragment extends Fragment implements 
     DatePickerDialog.OnDateSetListener, TimePickerDialog.OnTimeSetListener { 

    int day, month, year, hour, minute; 
    int dayFinal, monthFinal, yearFinal, hourFinal, minuteFinal; 
    String dayFinalString, monthFinalString, yearFinalString, hourFinalString, minuteFinalString; 

    TextView et2; 

    String dateFrom; 
    String Dates, time; 

    @Override 
    public void onDateSet(DatePicker datePicker, int i, int i1, int i2) { 
     yearFinal = i; 
     monthFinal = i1 + 1; 
     dayFinal = i2; 

     Calendar c = Calendar.getInstance(); 
     hour = c.get(Calendar.HOUR_OF_DAY); 
     minute = c.get(Calendar.MINUTE); 

     Dates = (monthFinal < 10 ? ("0" + monthFinal) : (monthFinal)) + "-" + (dayFinal < 10 ? ("0" + dayFinal) : (dayFinal)) + "-" + yearFinal ; 

     TimePickerDialog timePickerDialog = new TimePickerDialog(_context, this, hour, minute, DateFormat.is24HourFormat(_context)); 
     timePickerDialog.show(); 
    } 

    @Override 
    public void onTimeSet(TimePicker timePicker, int i, int i1) { 
     hourFinal = i; 
     minuteFinal = i1; 

     time = (hourFinal < 10 ? ("0" + hourFinal) : (hourFinal)) + ":" + (minuteFinal < 10 ? ("0" + minuteFinal) : (minuteFinal)); 



          //Here I want to set for example 
          et2.setText(Dates + " " + time + ":00"); 
          dateFromListFragment = et2.getText().toString(); 

          et3.setText(Dates + " " + time + ":00"); 
          dateFromListFragment = et3.getText().toString(); 


    } 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

     .... 

      @Override 
      public void onClick(View view) { 

       final Dialog dialog = new Dialog(getContext()); 

       dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
       dialog.setContentView(R.layout.date_time); 
       dialog.setCancelable(false); 

       ImageView close = (ImageView) dialog.findViewById(R.id.close); 
       close.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View view) { 
         dialog.dismiss(); 
        } 
       }); 

       et2 = (TextView) dialog.findViewById(R.id.editText2); 
       et2.setOnClickListener(new View.OnClickListener() { 
        public void onClick(View arg0) { 
         Calendar c = Calendar.getInstance(); 
         year = c.get(Calendar.YEAR); 
         month = c.get(Calendar.MONTH); 
         day = c.get(Calendar.DAY_OF_MONTH); 

         DatePickerDialog datePickerDialog = new DatePickerDialog(_context, SnailTrailTwoHrsFragment.this, year, month, day); 
         datePickerDialog.show(); 

        } 
       }); 

       final TextView et3 = (TextView) dialog.findViewById(R.id.editText3); 
       et3.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View view) { 
         Calendar c = Calendar.getInstance(); 
         year = c.get(Calendar.YEAR); 
         month = c.get(Calendar.MONTH); 
         day = c.get(Calendar.DAY_OF_MONTH); 

         DatePickerDialog datePickerDialog = new DatePickerDialog(_context, SnailTrailTwoHrsFragment.this, year, month, day); 
         datePickerDialog.show(); 

        } 
       }); 

} 

そして、ここでは、私がDate To TextViewと同じDate From TextViewを押すと、ダイアログで設定DateTimePickerを持つようにしたい私のXML

です。

問題：私はDate From TextViewを押すと、私は値がDate Time Pickerから来てDate Toと同じDate Fromに設定することができません取得できます。これを行うには
