Limit Time Range in Time Picker
提问by Sun
How to control TimePicker, I just want to show time range in time picker from 08:00 am to 02:00 pm (except from 08:00 am to 02:00 pm hide all)
如何控制TimePicker，我只想在时间选择器中显示从08:00 am到02:00 pm的时间范围（从08:00 am到02:00 pm隐藏所有）
I have written complete code to show TimePicker, and customized time as well.
我已经编写了完整的代码来显示 TimePicker，以及自定义时间。
Here is my code:
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;
}

As in this answer: https://stackoverflow.com/a/20396673/4130107You can create your custom TimePickerDialog and overwrite the onAttachedToWindow(); but instead limit the hour range:
在这个答案中：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();
}
}
EDIT: now working for AM/PM too
编辑：现在也为 AM/PM 工作
