先建立以个xml，然后拖拽TimerPicker;

TimePicker和TimePickerDiag

TimerPicker ：

先建立xml文件，然后拖拽TimePicker然后在MainActivity中实例化  同时还需要添加Calender  ，hour,minute

并通过单例模式获取calender的对象，然后获取hour,minute, 接着设置一个setTitle覆盖初始的title

通过timePicker.setOnTimeChangedListener()匿名内部类方法设置监听实现

通过new TimePickerDiag 实现

package com.example.timepickerdiag;

import java.util.Calendar;

import android.app.Activity;

import android.app.TimePickerDialog;

import android.app.TimePickerDialog.OnTimeSetListener;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.widget.TimePicker;

import android.widget.TimePicker.OnTimeChangedListener;

public class MainActivity extends Activity {

    private Calendar calendar;

    private TimePicker timePicker;

    private int hour;

    private int minute;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        calendar = calendar.getInstance();

        hour = calendar.get(calendar.HOUR);

        minute = calendar.get(calendar.MINUTE);

        timePicker = (TimePicker) findViewById(R.id.timePicker1);

        setTitle(hour + "-" + minute);

        timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {

            public void onTimeChanged(TimePicker view, int hour, int minute) {

                // TODO Auto-generated method stub

                setTitle(hour + "-" + minute);

            }

        });

        new TimePickerDialog(this, new OnTimeSetListener() {

            public void onTimeSet(TimePicker view, int hour, int minute) {

                // TODO Auto-generated method stub

                setTitle(hour + "-" + minute);

            }

        }, calendar.HOUR, minute, true).show();

    }

}

        setTitle(year + "-" + (calendar.MONTH + 1) + "-" + day);

        datePicker.init(year, calendar.MONTH, calendar.DAY_OF_MONTH,

                new OnDateChangedListener() {

                    }

                });

        new DatePickerDialog(this, new OnDateSetListener() {

            }
