Question

如何在时间选择器对话框中添加额外1小时。例如： - 如果当前时间是4.00平方米，那么我想在时间选择器中显示下午5点。

 final Calendar c = Calendar.getInstance();
                c.add(Calendar.HOUR,1);
                mHour = c.get(Calendar.HOUR_OF_DAY);
                mMinute = c.get(Calendar.MINUTE);

                // Launch Time Picker Dialog
                timePickerDialog = new TimePickerDialog(CheckOut.this,
                        new TimePickerDialog.OnTimeSetListener() {
                            @Override
                            public void onTimeSet(TimePicker view, int hourOfDay,
                                                  int minute) {

                                tvTimeSelect.setText("Delivery Time : "+hourOfDay + ":" + minute);
                                timePickerDialog.dismiss();
                            }
                        }, mHour, mMinute, false);
                timePickerDialog.show();

请告诉我解决方案......

Answer 1

您需要保持一致性。如果你得到HOUR_OF_DAY，那么你需要设置相同的

选项1 ：使用HOUR_OF_DAY

final Calendar c = Calendar.getInstance();
            c.add(Calendar.HOUR_OF_DAY,1);
            mHour = c.get(Calendar.HOUR_OF_DAY);
            mMinute = c.get(Calendar.MINUTE);

            // Launch Time Picker Dialog
            timePickerDialog = new TimePickerDialog(CheckOut.this,
                    new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker view, int hourOfDay,
                                              int minute) {

                            tvTimeSelect.setText("Delivery Time : "+hourOfDay + ":" + minute);
                            timePickerDialog.dismiss();
                        }
                    }, mHour, mMinute, false);
            timePickerDialog.show();

选项2 ：使用小时

final Calendar c = Calendar.getInstance();
            c.add(Calendar.HOUR,1);
            mHour = c.get(Calendar.HOUR);
            mMinute = c.get(Calendar.MINUTE);

            // Launch Time Picker Dialog
            timePickerDialog = new TimePickerDialog(CheckOut.this,
                    new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker view, int hourOfDay,
                                              int minute) {

                            tvTimeSelect.setText("Delivery Time : "+hourOfDay + ":" + minute);
                            timePickerDialog.dismiss();
                        }
                    }, mHour, mMinute, false);
            timePickerDialog.show();

Answer 2

试试这个c.add(Calendar.HOUR_OF_DAY,1);代替c.add(Calendar.HOUR,1);

Answer 3

检查一下，测试它的工作

Calendar mcurrentTime = Calendar.getInstance();
mcurrentTime.add(Calendar.HOUR,1);
int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
int minute = mcurrentTime.get(Calendar.MINUTE);
TimePickerDialog mTimePicker;
                    mTimePicker = new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                            tvTimeSelect.setText(selectedHour + ":" + selectedMinute);
                        }
                    }, hour, minute, true);//Yes 24 hour time
mTimePicker.setTitle("Select Time");
mTimePicker.show();

Answer 4

如果你想要12H而不是24H，你不应该把它改成这个吗？

mHour = c.get（Calendar.HOUR）;
