EDITTEXT定製：移動光標到下一個和多個零件輸入

Question

我需要我的EditText像下面的圖片，其中用戶可以輸入數字和完成後的位數限制光標移動到下一個。

更新：用戶可以從設定的DatePicker日期，月份&年從鍵盤&也單擊並設置日期。

Answer 1

這聽起來像所有你需要的是一個DatePicker，以便設置爲spinner

<DatePicker 
    ... 
    android:datePickerMode="spinner" 
    android:calendarViewShown="false" /> 

Answer 2

您可以使用TextWatcher類模式工作再上一個的EditText內的文本變化通知。

EditText mDayEditText; 
EditText mMonthEditText; 
EditText mYearEditText; 

TextWatcher dayTextWatcher = new TextWatcher() { 
    @Override 
    public void beforeTextChanged(CharSequence s, int start, int count, int after) { 
     // Do nothing... 
    } 

    @Override 
    public void onTextChanged(CharSequence s, int start, int before, int count) { 
     if (s.length() == 2) { 
      mMonthEditText.requestFocus(); 
     } 
    } 

    @Override 
    public void afterTextChanged(Editable s) { 
     // Do nothing... 
    } 
}; 

TextWatcher monthTextWatcher = new TextWatcher() { 
    @Override 
    public void beforeTextChanged(CharSequence s, int start, int count, int after) { 
     // Do nothing... 
    } 

    @Override 
    public void onTextChanged(CharSequence s, int start, int before, int count) { 
     if (s.length() == 2) { 
      mYearEditText.requestFocus(); 
     } 
    } 

    @Override 
    public void afterTextChanged(Editable s) { 
     // Do nothing... 
    } 
}; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    super.onCreateView(inflater, container, savedInstanceState); 
    View v = inflater.inflate(R.layout.your_fragment, container, false); 

    mDayEditText = (EditText) v.findViewById(R.id.text_view_1); 
    mMonthEditText = (EditText) v.findViewById(R.id.text_view_2); 
    mYearEditText = (EditText) v.findViewById(R.id.text_view_3); 

    mDayEditText.addTextChangedListener(dayTextWatcher); 
    mMonthEditText.addTextChangedListener(monthTextWatcher); 
}
