android-studio - Android Studio 3.1.1 中的时间和日期选择器在哪里？

Question

我刚刚升级到 Android Studio 3.1.1，现在找不到时间和日期选择器。

我在 Linux 机器上运行，Android Studio 建议升级，我只是点击了“确定”。下面是我的调色板的屏幕截图:

知道在哪里可以找到它们吗？我在找这两个人:

我想你要找的是 DatePickerDialog 和 TimePickerDialog。您可以通过编程方式添加它。本例中的 onclick edittext 事件。对于 DatePickerDialog :

    final Calendar myCalendar = Calendar.getInstance();

    final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {

        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear,
                              int dayOfMonth) {
            // TODO Auto-generated method stub
            myCalendar.set(Calendar.YEAR, year);
            myCalendar.set(Calendar.MONTH, monthOfYear);
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

            String myFormat = "dd/MM/yyyy"; //set date format
            SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

            YourDateEditText.setText(sdf.format(myCalendar.getTime()));
        }

    };

    YourDateEditText.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            new DatePickerDialog(YourActivity.this, date, myCalendar
                    .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                    myCalendar.get(Calendar.DAY_OF_MONTH)).show();
        }
    });

对于 TimePickerDialog :

YourTimeEditText.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Calendar mcurrentTime = Calendar.getInstance();
            int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
            int minute = mcurrentTime.get(Calendar.MINUTE);

            TimePickerDialog mTimePicker;
            mTimePicker = new TimePickerDialog(YourActivity.this, new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                    YourTimeEditText.setText( selectedHour + ":" + selectedMinute);
                }
            }, hour, minute, true);
            mTimePicker.setTitle("Select Time");
            mTimePicker.show();
        }
    });
