EDITTEXT定制：移动光标到下一个和多个零件输入

Question

我需要我的EditText像下面的图片，其中用户可以输入数字和完成后的位数限制光标移动到下一个。

更新：用户可以从设定的DatePicker日期，月份&年从键盘&也单击并设置日期。

Answer 1

这听起来像所有你需要的是一个DatePicker，以便设置为spinner

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

Answer 2

您可以使用TextWatcher类模式工作再上一个的EditText内的文本变化通知。

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); 
}
