如何控制TimePicker，我只想在时间选择器中显示08:00 am到02:00 pm的时间范围(除了08:00 am到02:00 pm全部隐藏)

我已经编写了完整的代码来显示TimePicker，也可以自定义时间。

这是我的代码:

         case DIALOG_TIME:
            final Calendar c = Calendar.getInstance();
            int hour = c.get(Calendar.HOUR_OF_DAY);
            int minute = c.get(Calendar.MINUTE);

            // Create a new instance of TimePickerDialog and return it
            return new TimePickerDialog(this, lisTime, hour, minute,
            DateFormat.is24HourFormat(MainActivity.this));

        TimePickerDialog.OnTimeSetListener lisTime = new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            // TODO Auto-generated method stub
            String meridiem = "";
            nim = minute;
            Calendar datetime = Calendar.getInstance();
            datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
            datetime.set(Calendar.MINUTE, minute);

            if (datetime.get(Calendar.AM_PM) == Calendar.AM)
                meridiem = "AM";
            else if (datetime.get(Calendar.AM_PM) == Calendar.PM)
                meridiem = "PM";

            hour = (datetime.get(Calendar.HOUR) == 0) ?"12":String.valueOf(datetime.get(Calendar.HOUR));

            String time = pad(Integer.parseInt(hour)) + ":" + pad(minute) + " " + meridiem;
            editTime.setText(time);

        }
    };

    private String pad(int value){

        if(value<10){
            return "0"+value;
        }

        return ""+value;
    }

最佳答案

正如这个答案:https://stackoverflow.com/a/20396673/4130107 您可以创建自定义 TimePickerDialog 并覆盖 onAttachedToWindow()；而是限制小时范围:

private final boolean mIs24HourView;

public CustomTimePickerDialog(Context context, OnTimeSetListener callBack,
                              int hourOfDay, int minute, boolean is24HourView) {
    super(context, callBack, hourOfDay, minute, is24HourView);
    mIs24HourView = is24HourView;
}

@Override
public void onAttachedToWindow() {
    super.onAttachedToWindow();
    try {
        Class<?> classForid = Class.forName("com.android.internal.R$id");
        Field timePickerField = classForid.getField("timePicker");
        this.timePicker = (TimePicker) findViewById(timePickerField
                .getInt(null));
        Field field = classForid.getField("hour");


        final NumberPicker mHourSpinner = (NumberPicker) timePicker
                .findViewById(field.getInt(null));

        if (mIs24HourView) {
            mHourSpinner.setMinValue(2);
            mHourSpinner.setMaxValue(20);
        }else {
            Field amPm = classForid.getField("amPm");

            mHourSpinner.setMinValue(2);
            final NumberPicker amPm = (NumberPicker) timePicker
                    .findViewById(amPm.getInt(null));
            amPm.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {
                @Override
                public void onValueChange(NumberPicker np1, int oldVal, int newVal) {
                    if (newVal == 0) { // case AM
                        mHourSpinner.setMinValue(2);
                        mHourSpinner.setMaxValue(12);
                    } else { // case PM
                        mHourSpinner.setMinValue(1);
                        mHourSpinner.setMaxValue(8);
                    }
                }
            });

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

}
