TimePicker 和TimePickerDiag

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();

    }

}

        datePicker.init(year, calendar.MONTH, calendar.DAY_OF_MONTH,
                new OnDateChangedListener() {
