如何在android中设置自定义分钟间隔timepickerdialog

Posted 2023-03-06

android如果要修改自定义分钟间隔，通常的做法是重写一个TimePickerDialog，继承它，不过也可以通过监听事件来监听数值的改变，来显示自定义的分钟间隔，代码如下：
private static final int TIME_PICKER_INTERVAL=15;
private boolean mIgnoreEvent=false;

private TimePicker.OnTimeChangedListener mTimePickerListener=new TimePicker.OnTimeChangedListener()
public void onTimeChanged(TimePicker timePicker, int hourOfDay, int minute)
if (mIgnoreEvent)
return;
if (minute%TIME_PICKER_INTERVAL!=0)
int minuteFloor=minute-(minute%TIME_PICKER_INTERVAL);
minute=minuteFloor + (minute==minuteFloor+1 ? TIME_PICKER_INTERVAL : 0);
if (minute==60)
minute=0;
mIgnoreEvent=true;
timePicker.setCurrentMinute(minute);
mIgnoreEvent=false;



; 参考技术A public class CustomTimePickerDialog extends TimePickerDialog
public static final int TIME_PICKER_INTERVAL=10;
private boolean mIgnoreEvent=false;
public CustomTimePickerDialog(Context context, OnTimeSetListener callBack, int hourOfDay, int minute,
boolean is24HourView)
super(context, callBack, hourOfDay, minute, is24HourView);

/*
* (non-Javadoc)
* @see android.app.TimePickerDialog#onTimeChanged(android.widget.TimePicker, int, int)
* Implements Time Change Interval
*/
@Override
public void onTimeChanged(TimePicker timePicker, int hourOfDay, int minute)
super.onTimeChanged(timePicker, hourOfDay, minute);
this.setTitle("2. Select Time");
if (!mIgnoreEvent)
minute = getRoundedMinute(minute);
mIgnoreEvent=true;
timePicker.setCurrentMinute(minute);
mIgnoreEvent=false;


public static int getRoundedMinute(int minute)
if(minute % TIME_PICKER_INTERVAL != 0)
int minuteFloor = minute - (minute % TIME_PICKER_INTERVAL);
minute = minuteFloor + (minute == minuteFloor + 1 ? TIME_PICKER_INTERVAL : 0);
if (minute == 60) minute=0;

return minute;



这个类，所有你需要做的，而不是在你的代码来访问类/覆盖默认函数。在简单的方法，你会因为在此之后下... private CustomTimePickerDialog.OnTimeSetListener timeSetListener = new CustomTimePickerDialog.OnTimeSetListener()
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute)
