Android动态显示当前年月日时分秒系统时间(示例代码)

概述在布局文件中放一个TextView用来显示时间，如下所示：<?xmlversion=\"1.0\"encoding=\"utf-8\"?>

在布局文件中放一个TextVIEw用来显示时间，如下所示：

<?xml version="1.0" enCoding="utf-8"?>  <linearLayout  xmlns:androID="http://schemas.androID.com/apk/res/androID"  androID:layout_wIDth="match_parent"  androID:layout_height="match_parent"  androID:background="@androID:color/white">  <TextVIEw   androID:ID="@+ID/mytime"   androID:layout_wIDth="match_parent"   androID:layout_height="match_parent"   androID:gravity="center"   androID:textcolor="@androID:color/black"   androID:textSize="36sp"/>  </linearLayout> 

开启一个线程，然后通过handler发消息，来实时的更新TextVIEw上显示的系统时间：

import androID.app.Activity;  import androID.os.Bundle;  import androID.os.Handler;  import androID.os.Message;  import androID.text.format.DateFormat;  import androID.Widget.TextVIEw;  public class TestActivity extends Activity {    private static final int msgKey1 = 1;    private TextVIEw mTime;    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentVIEw(R.layout.time);      mTime = (TextVIEw) findVIEwByID(R.ID.mytime);      new TimeThread().start();    }    public class TimeThread extends Thread {      @OverrIDe      public voID run () {        do {          try {            Thread.sleep(1000);            Message msg = new Message();            msg.what = msgKey1;            mHandler.sendMessage(msg);          }          catch (InterruptedException e) {            e.printstacktrace();          }        } while(true);      }    }    private Handler mHandler = new Handler() {      @OverrIDe      public voID handleMessage (Message msg) {        super.handleMessage(msg);        switch (msg.what) {          case msgKey1:            mTime.setText(getTime());            break;          default:            break;        }      }    };    //获得当前年月日时分秒星期    public String getTime(){      final Calendar c = Calendar.getInstance();      c.setTimeZone(TimeZone.getTimeZone("GMT+8:00"));      String mYear = String.valueOf(c.get(Calendar.YEAR)); // 获取当前年份      String mMonth = String.valueOf(c.get(Calendar.MONTH) + 1);// 获取当前月份      String mDay = String.valueOf(c.get(Calendar.DAY_OF_MONTH));// 获取当前月份的日期号码      String mWay = String.valueOf(c.get(Calendar.DAY_OF_WEEK));      String mHour = String.valueOf(c.get(Calendar.HOUR_OF_DAY));//时      String mMinute = String.valueOf(c.get(Calendar.MINUTE));//分      String mSecond = String.valueOf(c.get(Calendar.SECOND));//秒      if("1".equals(mWay)){        mWay ="天";      }else if("2".equals(mWay)){        mWay ="一";      }else if("3".equals(mWay)){        mWay ="二";      }else if("4".equals(mWay)){        mWay ="三";      }else if("5".equals(mWay)){        mWay ="四";      }else if("6".equals(mWay)){        mWay ="五";      }else if("7".equals(mWay)){        mWay ="六";      }      return mYear + "年" + mMonth + "月" + mDay+"日"+" "+"星期"+mWay+" "+mHour+":"+mMinute+":"+mSecond;    }  }
