 int day = view.getDayOfMonth(); 
     int month= view.getMonth(); 
     int year = view.getYear(); 

     SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); 
     String formatedDate = sdf.format(new Date(year, month, day)); 
     Log.d("test", "" + formatedDate);//Here i'am retrieving 3914 instead 2014 

Answer 1

根据the documentation，Date()的第一个参数是“年份减去1900年“。这就是为什么你得到3914（= 2014 + 1900）。正如文件还指出，使用Calendar或GregorianCalendar而不是Date。

Answer 2

你更好地与日历的工作，这里有一个简单的例子：

public Dialog onCreateDialog(Bundle savedInstanceState) { 
    // Use the current date as the default date in the picker 
    final Calendar c = Calendar.getInstance(); 
    int year = c.get(Calendar.YEAR); 
    int month = c.get(Calendar.MONTH); 
    int day = c.get(Calendar.DAY_OF_MONTH); 

    // Create a new instance of DatePickerDialog and return it 
    return new DatePickerDialog(getActivity(), this, year, month, day); 
} 

public void onDateSet(DatePicker view, int year, int month, int day) { 
    // Do something with the date chosen by the user 
    int [] tabd=new int[3]; 
tabd[0]=day; 
    tabd[1]=month+1; 
    tabd[2]=year; 
    Button b1=(Button)getActivity().findViewById(R.id.yourButton); 
    String d=tabd[0]+"-"+tabd[1]+"-"+tabd[2]; 
// d is your string that contain the date now you can do whatever you want with it 

}
