android - 从 DatePickerDialog 中删除年份

Question

我正在使用 Android 的基本 DatePickerDialog 教程，可在此处找到 Android Date Picker

我已经开始工作了。但我只想从今年挑一个日期。那么有没有办法把Dialog中的年去掉，只显示月和日呢？每次我尝试取出 Year int 时，它都会破坏代码。

Answer 1

是的，有可能。 DatePicker内置了三个NumberPicker控件，依次是年、月、日，先隐藏出来。

final Calendar cal = Calendar.getInstance();
mDialog = new CustomerDatePickerDialog(getContext(), this,
cal.get(Calendar.YEAR), cal.get(Calendar.MONTH),
cal.get(Calendar.DAY_OF_MONTH));
mDialog.show();
DatePicker dp = findDatePicker((ViewGroup) mDialog.getWindow().getDecorView());
if (dp != null) {
    ((ViewGroup) dp.getChildAt(0)).getChildAt(0).setVisibility(View.GONE);
} 

CustomerDatePickerDialog

class CustomerDatePickerDialog extends DatePickerDialog {
     public CustomerDatePickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) {
         super(context, callBack, year, monthOfYear, dayOfMonth);
     }

     @Override
     public void onDateChanged(DatePicker view, int year, int month, int day) {
         super.onDateChanged(view, year, month, day);
         mDialog.setTitle((month + 1) + "-" + day + "-");
     }
}

日期选择器:

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;
                } else if (child instanceof ViewGroup) {
                    DatePicker result = findDatePicker((ViewGroup) child);
                    if (result != null)
                        return result;
                }
            }
        }
        return null;

    }
