android获得系统时间（Handler）

package com.bawei.layout;

import java.util.Calendar;

import android.app.Activity;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import android.widget.TextView;

public class TimeActivity extends  Activity{
private static final int GUINOTIFIER =1;

//然后定义一些例子 里面需要的属性

public Calendar mCalendar;
// public int mMinutes;
// public int mHour; //小时
private int myear;//年
private int mmonth;//月
private int mday;//天
private int mminute;//分钟
private int mhour;//小时
private int msecond;//秒
private int mweek;//星期
private  Handler mHandler;
private Thread mClockThread;
private TextView mtextview;

protected void onCreate(android.os.Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.time);

mtextview = (TextView) findViewById(R.id.time_textview);
//接着我们通过Handler来接收Thread所传递的信息
   result();
mHandler = new Handler() {
        public void handleMessage(Message msg) {
            switch (msg.what) {
                case TimeActivity.GUINOTIFIER://TestHandler是Activity的类名
                    //得到Handle的通知了 这个时候你可以做相应的操作，本例是使用TextView 来显示时间
                mtextview .setText(myear + "年" + mmonth+"月"+ mday +"日"+mhour +"："+mminute+":"+msecond+"星期"+mweek);
                    break;
            }
            super.handleMessage(msg);
        }
    };
}


//接下来我们自定义一个Thread

class LooperThread extends Thread {
    public void run() {
        super.run();
        try {
            do {
            //每间隔一秒取一次系统 时间
                long time = System.currentTimeMillis();
                final Calendar mCalendar = Calendar.getInstance();
                mCalendar.setTimeInMillis(time);
                  //  取得系统日期:
                    myear = mCalendar.get(Calendar.YEAR);
                        mmonth = mCalendar.get(Calendar.MONTH);
                        mday = mCalendar.get(Calendar.DAY_OF_MONTH);
                  // 取得系统时间：
                          mhour = mCalendar.get(Calendar.HOUR_OF_DAY);
                          mminute = mCalendar.get(Calendar.MINUTE);
                          msecond= mCalendar.get(Calendar.SECOND);
                          mweek = mCalendar.get(Calendar.DAY_OF_WEEK);
                         
               
                Thread.sleep(1000);
                //取得系统时间后发送消息给Handler
                Message m = new Message();
                m.what = GUINOTIFIER;
                mHandler.sendMessage(m);
            } while (!LooperThread.interrupted());//当系统发出终端命令时停止循环
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
   //最后我们启动线程
public void result(){
   mClockThread = new LooperThread();
   mClockThread.start();
    }

   
}
