android timepicker 秒,在Android中以分钟间隔显示TimePicker

使用以下自定义类CustomTimePickerDialog，我认为解决你的问题。

import java.lang.reflect.Field;

import java.util.ArrayList;

import java.util.List;

import android.app.TimePickerDialog;

import android.content.Context;

import android.content.DialogInterface;

import android.widget.NumberPicker;

import android.widget.TimePicker;

public class CustomTimePickerDialog extends TimePickerDialog {

private final static int TIME_PICKER_INTERVAL = 5;

private TimePicker mTimePicker;

private final OnTimeSetListener mTimeSetListener;

public CustomTimePickerDialog(Context context, OnTimeSetListener listener,

int hourOfDay, int minute, boolean is24HourView) {

super(context, TimePickerDialog.THEME_HOLO_LIGHT, null, hourOfDay,

minute / TIME_PICKER_INTERVAL, is24HourView);

mTimeSetListener = listener;

}

@Override

public void updateTime(int hourOfDay, int minuteOfHour) {

mTimePicker.setCurrentHour(hourOfDay);

mTimePicker.setCurrentMinute(minuteOfHour / TIME_PICKER_INTERVAL);

}

@Override

public void onClick(DialogInterface dialog, int which) {

switch (which) {

case BUTTON_POSITIVE:

if (mTimeSetListener != null) {

mTimeSetListener.onTimeSet(mTimePicker, mTimePicker.getCurrentHour(),

mTimePicker.getCurrentMinute() * TIME_PICKER_INTERVAL);

}

break;

case BUTTON_NEGATIVE:

cancel();

break;

}

}

@Override

public void onAttachedToWindow() {

super.onAttachedToWindow();

try {

Class> classForid = Class.forName("com.android.internal.R$id");

Field timePickerField = classForid.getField("timePicker");

mTimePicker = (TimePicker) findViewById(timePickerField.getInt(null));

Field field = classForid.getField("minute");

NumberPicker minuteSpinner = (NumberPicker) mTimePicker

.findViewById(field.getInt(null));

minuteSpinner.setMinValue(0);

minuteSpinner.setMaxValue((60 / TIME_PICKER_INTERVAL) - 1);

List displayedValues = new ArrayList<>();

for (int i = 0; i < 60; i += TIME_PICKER_INTERVAL) {

displayedValues.add(String.format("%02d", i));

}

minuteSpinner.setDisplayedValues(displayedValues

.toArray(new String[displayedValues.size()]));

} catch (Exception e) {

e.printStackTrace();

}

}

}
