在代码中用法：

private void showDatePicker() {
		//获取当前日期
		Calendar calendar = Calendar.getInstance();
		year = calendar.get(Calendar.YEAR);
		month = calendar.get(Calendar.MONTH);
		day = calendar.get(Calendar.DAY_OF_MONTH);
		
		//创建并显示DatePickerDialog
		DatePickerDialog dialog = new DatePickerDialog(this, Datelistener, year, month, day);
		dialog.show();
		
		//只显示年月，隐藏掉日
		DatePicker dp = findDatePicker((ViewGroup) dialog.getWindow().getDecorView());
		if (dp != null) {
			((ViewGroup)((ViewGroup)dp.getChildAt(0)).getChildAt(0))
									.getChildAt(2).setVisibility(View.GONE);
			//如果想隐藏掉年，将getChildAt(2)改为getChildAt(0)
		}
	}

findDatePicker方法

private DatePicker findDatePicker(ViewGroup group) {
   if (group != null) {
      for (int i = 0, j = group.getChildCount(); i < j; i++) {
         View child = group.getChildAt(i);
         if (child instanceof DatePicker) {
            return (DatePicker) child
