フラグメント内のedittextから値を取得できません

Question

私は新しいです...

私の質問は：どのように断片的に編集テキストからデータを取得するのですか？私は本当に私が求めているすべてのものを試しましたが、結果はありませんでした。ここで

コードです：

PersonalDataFragment.java パブリッククラスPersonalDataFragmentは、私は私が間違っているのかわからない断片{

public EditText editText; 
public Calendar myCalendar; 
public DatePickerDialog.OnDateSetListener uDate; 
private getEditText listener = null; 

public PersonalDataFragment() { 
    // Required empty public constructor 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

    View v = inflater.inflate(R.layout.fragment_pdata, null); 

    //Calendar 
    editText = (EditText) v.findViewById(R.id.input_birthday); 
    final EditText i_lname = (EditText) v.findViewById(R.id.input_lName); 
    editText.setTextIsSelectable(true); 

    myCalendar = Calendar.getInstance(); 

    uDate = new DatePickerDialog.OnDateSetListener() { 

     @Override 
     public void onDateSet(DatePicker view, int year, int monthOfYear, 
           int dayOfMonth) { 
      // TODO Auto-generated method stub 
      myCalendar.set(Calendar.YEAR, year); 
      myCalendar.set(Calendar.MONTH, monthOfYear); 
      myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth); 
      updateLabel(); 
     } 

    }; 

    editText.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View vi) { 
      // TODO Auto-generated method stub 
      new DatePickerDialog(getActivity(), uDate, myCalendar 
        .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), 
        myCalendar.get(Calendar.DAY_OF_MONTH)).show(); 
     } 
    }); 

    //Getting EditTexts 
    i_lname.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 (listener != null) { 
       final String stg = i_lname.getText().toString(); 
       listener.onFragmentEditTextChanged(stg); 
       Toast.makeText(getActivity(), stg, Toast.LENGTH_SHORT).show(); 
      } 
     } 
    }); 
    return v; 
} 

@Override 
public void onAttach(Context context) { 
    listener = (getEditText) context; 
} 

private void updateLabel() { 
    String myFormat = "dd/MM/yy"; 
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US); 

    editText.setText(sdf.format(myCalendar.getTime())); 
} 

public interface getEditText { 
    public void onFragmentEditTextChanged(String lname); 
} 

}

を拡張します。私はそれらを利用するためにそれらのEditTextへのアクセスを取得し、ユーザーをSQLite DBに追加する必要がありますが、EditTextはFragmentにあるため、RegisterUserクラスから直接アクセスすることはできません。

これを解決する方法はありますか？私は本当に深く感謝します。

ありがとうございます。

は次のようにやって試してみてください、

TextInputLayout FlayoutBirthday= (TextInputLayout) v.findViewById(R.id.flayout_birthday); 
EditText i_lname = FlayoutBirthday.getEditText();
