【问题描述】：

当日期选择器返回selected date 时，代码应自动显示时间选择器。当时间选择器返回时，活动应该"Toast" 选择的日期和时间。

FloatingActionButton dateFab = findViewById(R.id.datePicker);
       dateFab.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View view) 
                //Open Date Picker Fragment

            DatePickerFragment newFragment = new DatePickerFragment();
            newFragment.setListener(MainActivity.this);
            newFragment.show(getSupportFragmentManager(),
                    "Pick the Date");
            TimePickerFragment newFragment1 = new TimePickerFragment();
            newFragment1.setListener(MainActivity.this);
            newFragment1.show(getSupportFragmentManager(),
                    "Pick the Time");

        
    );

【参考方案1】：

在我的情况下，它是多个字段，需要设置，因此我将它们作为函数中的参数传递。设置日期后只需调用 timepicker 函数。

 private void showDatePickerDialog(final EditText etDates) 
    final Calendar c = Calendar.getInstance();
    int mYear = c.get(Calendar.YEAR);
    int mMonth = c.get(Calendar.MONTH);
    int mDay = c.get(Calendar.DAY_OF_MONTH);


    DatePickerDialog datePickerDialog = new DatePickerDialog(mContext,
            new DatePickerDialog.OnDateSetListener() 

                @Override
                public void onDateSet(DatePicker view, int year,
                                      int monthOfYear, int dayOfMonth) 


                    etDates.setText( (monthOfYear + 1) + "-" + dayOfMonth + "-" +year 
                    showTimePickerDialog(etTime);

                
            , mYear, mMonth, mDay);
    datePickerDialog.setTitle("Select Date");
    datePickerDialog.show();



private void showTimePickerDialog(final EditText etTime) 
    Calendar mcurrentTime = Calendar.getInstance();
    int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
    int minute = mcurrentTime.get(Calendar.MINUTE);
    TimePickerDialog mTimePicker;
    mTimePicker = new TimePickerDialog(mContext, new TimePickerDialog.OnTimeSetListener() 
        @Override
        public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) 
            etTime.setText(selectedHour + ":" + selectedMinute);
        
    , hour, minute, true);//Yes 24 hour time
    mTimePicker.setTitle("Select Time");
    mTimePicker.show();
