Block Hour TimePicker

Question

我有一个字段可以通过TimerPicker来选择时间。

它的工作完美。

我正在寻找一种方法来限制或在某些时候阻止访问。

例如： 开放的领域和关闭时间，保存在公司的FireStore（火力地堡）：

- Start time: 08:00 
- HourEnd: 7:00 p.m. 

我需要的结束时间之后，阻断开始时间之前的时间，和小时。

代码TimePicker：

private void timePicker(){ 

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

     TimePickerDialog timePickerDialog = new TimePickerDialog(this, 
       new TimePickerDialog.OnTimeSetListener() { 

        @Override 
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 

         mHour = hourOfDay; 
         mMinute = minute; 


         /*Formato da hora*/ 
         String curTime = String.format("%02d:%02d", hourOfDay, minute); 

         mHora.setText(curTime); 
         mHoraString = curTime; 

        } 
       }, mHour, mMinute, true); 
     timePickerDialog.show(); 
}

我希望这给你如何实现你在找什么的想法。我意识到这不是您正在寻找的确切解决方案，但它是一个开始。

这是我用于我的TimePickerDialogFragment的代码。这是为了显示TimePicker某些间隔的分钟段（如5，10，或15分钟）。

在这种会叫你将需要实现回调监听器TimePickerDialogFragment活动：

implements TimePickerDialogFragment.EditTimeDialogListener 

然后你可以像这样调用对话框。本实施例中，使分进入15分钟的间隔：

TimePickerDialogFragment picker = TimePickerDialogFragment.newInstance("Select a Time", initialStartHour, 15); 
    picker.show(getFragmentManager(), "TimePickerDialogFragment"); 

initialStartHour是我initalize拾取器具有例如10对于10 AM的小时。

我的TimePickerDialogFragment的代码设置为设置间隔分钟。

public class TimePickerDialogFragment extends DialogFragment { 

    private static final String ARG_TITLE = "title"; 
    private static final String ARG_START_HOUR = "startHour"; 
    private static final String ARG_MINUTE_INTERVAL = "minute_interval"; 

    private static final DecimalFormat FORMATTER = new DecimalFormat("00"); 
    NumberPicker minutePicker; 

    private String title; 
    private int startHour; 
    private int minuteInterval; 
    private String selectedTime; 

    private EditTimeDialogListener mListener; 

    public TimePickerDialogFragment() { 
    } 

    public static TimePickerDialogFragment newInstance(String title, int startHour, int minuteInterval) { 
     TimePickerDialogFragment fragment = new TimePickerDialogFragment(); 
     Bundle args = new Bundle(); 
     args.putString(ARG_TITLE, title); 
     args.putInt(ARG_START_HOUR, startHour); 
     args.putInt(ARG_MINUTE_INTERVAL, minuteInterval); 
     fragment.setArguments(args); 
     return fragment; 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     if (getArguments() != null) { 
      title = getArguments().getString(ARG_TITLE); 
      startHour = getArguments().getInt(ARG_START_HOUR); 
      minuteInterval = getArguments().getInt(ARG_MINUTE_INTERVAL); 
     } 
    } 

    @Override 
    public Dialog onCreateDialog(Bundle saveIntsanceState){ 

     final Context context = getActivity(); 

     AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 

     LayoutInflater inflater = getActivity().getLayoutInflater(); 

     View rootView = inflater.inflate(R.layout.fragment_time_picker_dialog, null, false); 
     final TimePicker picker = (TimePicker) rootView.findViewById(R.id.timePicker); 
     View minute = picker.findViewById(Resources.getSystem().getIdentifier("minute", "id", "android")); 
     setMinutePicker(minute); 

     //Block number keyboard 
     picker.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS); 

     picker.setCurrentHour(startHour); 
     picker.setCurrentMinute(0); 
     // setHour is available for API level 23 and above!! 
//  picker.setHour(startHour); 

     final TextView tvTitle = (TextView)rootView.findViewById(R.id.tvTimePickerDialogTitle); 
     tvTitle.setText(title); 
//  picker.setSpinnersShown(false); 
//  picker.setCalendarViewShown(true); 

     builder.setView(rootView) 
     // setTitle is available for API level 23 and above!! 
//    .setTitle(title) 
       .setPositiveButton(R.string.ok_button_dialog_title, new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         // call the method on the parent activity when user click the positive button 

         Integer h = picker.getCurrentHour(); 
         Integer m = picker.getCurrentMinute() * minuteInterval; 

         String hh = h.toString(); 
         if(h < 10){ 
          hh = "0" + hh; 
         } 

         String mm = m.toString(); 
         if(m < 10){ 
          mm = "0" + mm; 
         } 

         selectedTime = hh + mm; 
         if(mListener == null) mListener = (EditTimeDialogListener) context; 
         mListener.onFinishTimeDialog(selectedTime); 
        } 
       }) 
       .setNegativeButton(R.string.cancel_button_dialog_title, new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         // call the method on the parent activity when user click the negative button 
        } 
       }); 
     return builder.create(); 
    } 

    private void setMinutePicker(View minute){ 
     int n = 60/minuteInterval; 
     String[] displayValues = new String[n]; 

     for(int i = 0; i < n; i++){ 
      displayValues[i] = FORMATTER.format(i*minuteInterval); 
     } 

     if((minute != null) && (minute instanceof NumberPicker)){ 
      minutePicker = (NumberPicker) minute; 

      minutePicker.setMinValue(0); 
      minutePicker.setMaxValue(n-1); 
      minutePicker.setDisplayedValues(displayValues); 
     } 
    } 


    @Override 
    public void onAttach(Context context) { 
     super.onAttach(context); 
     try { 
      if(mListener == null) mListener = (EditTimeDialogListener) context; 
     } 
     catch (Exception ex){ 
      throw new RuntimeException(context.toString() 
        + " must implement OnFragmentInteractionListener"); 
     } 
    } 

    @Override 
    public void onDetach() { 
     super.onDetach(); 
     mListener = null; 
    } 

    public interface EditTimeDialogListener { 
     void onFinishTimeDialog(String selectedTime); 
    } 

} 

现在，所有你需要做的是提取您的电话活动与该片段中选择的时间：

@Override 
public void onFinishTimeDialog(String selectedTime) { 
     // Now set the TextView text!! 
     mHora.setText(selectedTime); 
}
