Java 如何从DatePickerDialog获取月份和年份？

这是我的代码：

    public DatePickerDialog CREATE_DATEPICKER_DIALOG() {
        int themeResId = 2;
        datePickerDialog = new DatePickerDialog(this, themeResId, null, 2018, 1, 1);
        datePickerDialog.getDatePicker().setMinDate(get_min_calendar);
        datePickerDialog.getDatePicker().setMaxDate(get_max_calendar);

        try {
            // Hide selected day.
            ((ViewGroup) datePickerDialog.getDatePicker()).findViewById(Resources.getSystem().getIdentifier("day", "id", "android")).setVisibility(View.GONE);
            datePickerDialog.updateDate(datePickerDialog.getDatePicker().getYear(), datePickerDialog.getDatePicker().getMonth(), 0);
            datePickerDialog.setTitle("Change Month");
            datePickerDialog.setButton(DialogInterface.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    if(which==DialogInterface.BUTTON_POSITIVE){
                    TXT_MONTH.setText("MONTH_HERE");<----- datePickerDialog.getDatePicker().getMonth();
                    TXT_YEAR.setText("YEAR_HERE");<-----datePickerDialog.getDatePicker().getYear();
                    }else{

                    }
                }

            });
        } catch (Exception e) {
            e.printStackTrace();
        }

        return datePickerDialog;
}

public DatePickerDialog CREATE\u DATEPICKER\u DIALOG（）{
int-themeResId=2；
datePickerDialog=新的datePickerDialog（this，themeResId，null，2018,1,1）；
datePickerDialog.getDatePicker（）.setMinDate（获取日历）；
datePickerDialog.getDatePicker（）.setMaxDate（获取日历）；
试一试{
//隐藏所选日期。
（（ViewGroup）datePickerDialog.getDatePicker（））.findViewById（Resources.getSystem（）.getIdentifier（“day”、“id”、“android”））.setVisibility（View.GONE）；
datePickerDialog.updateDate（datePickerDialog.getDatePicker（）.getYear（），datePickerDialog.getDatePicker（）.getMonth（），0）；
datePickerDialog.setTitle（“变更月”）；
datePickerDialog.setButton（DialogInterface.BUTTON_“确定”，新的DialogInterface.OnClickListener（）{
@凌驾
public void onClick（DialogInterface dialog，int which）{
if（which==DialogInterface.BUTTON_正值）{
TXT_MONTH.setText（“这里的MONTH_”）解决方案：我建议您使用不同的
DatePickerDialog
，我目前也在我的项目中使用它。它很容易使用，请按照以下步骤操作：

步骤1:在你的Gradle中添加依赖项（应用程序级别）：

第二步：在应用程序中使用它：

try {
    Calendar now = Calendar.getInstance();

    DatePickerDialog dpd = DatePickerDialog.newInstance(

            new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
                    .......
                    // Get Year, Month and Day from the parameter here when you select and date.
                    .......
                }
            },
            now.get(Calendar.YEAR),
            now.get(Calendar.MONTH),
            now.get(Calendar.DAY_OF_MONTH)
    );
    dpd.setAccentColor(ContextCompat.getColor(FilterForLoadBoardActivity.this, R.color.colorPrimary));
    dpd.setMinDate(now);
    dpd.show(getFragmentManager(), "Datepickerdialog");
    return;
} catch (Exception e) {
    e.printStackTrace();
}

最后：您的方法应该如下所示：

public DatePickerDialog CREATE_DATEPICKER_DIALOG() {
......
......
......
DatePickerDialog dpd;

try {
Calendar now = Calendar.getInstance();

dpd = DatePickerDialog.newInstance(new DatePickerDialog.OnDateSetListener() {
             @Override
             public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
                 .......
                 // Get Year, Month and Day from the parameter here when you select and date.
                 .......
                 }
             },
             now.get(Calendar.YEAR),
             now.get(Calendar.MONTH),
             now.get(Calendar.DAY_OF_MONTH)
         );
        dpd.setAccentColor(ContextCompat.getColor(FilterForLoadBoardActivity.this, R.color.colorPrimary));
        dpd.setMinDate(now);
        dpd.show(getFragmentManager(), "Datepickerdialog");
     } catch (Exception e) {
        e.printStackTrace();
     }
     return dpd;
}

试试看，希望有帮助。
试试这个

TXT_MONTH.setText（月[datePickerDialog.getDatePicker（）.getMonth（）]）；
TXT_YEAR.setText（Integer.toString（datePickerDialog.getDatePicker（）.getYear（））；
什么东西不起作用？你能发布你的datePickerDialog的代码吗？我无法获取所选月份和年份的值What is months？字符串months[]={“一月”、“二月”、“等等”}
public DatePickerDialog CREATE_DATEPICKER_DIALOG() {
......
......
......
DatePickerDialog dpd;

try {
Calendar now = Calendar.getInstance();

dpd = DatePickerDialog.newInstance(new DatePickerDialog.OnDateSetListener() {
             @Override
             public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
                 .......
                 // Get Year, Month and Day from the parameter here when you select and date.
                 .......
                 }
             },
             now.get(Calendar.YEAR),
             now.get(Calendar.MONTH),
             now.get(Calendar.DAY_OF_MONTH)
         );
        dpd.setAccentColor(ContextCompat.getColor(FilterForLoadBoardActivity.this, R.color.colorPrimary));
        dpd.setMinDate(now);
        dpd.show(getFragmentManager(), "Datepickerdialog");
     } catch (Exception e) {
        e.printStackTrace();
     }
     return dpd;
}
