【Android 开发 重写定位器类Timer与TimerTask】相逢意气为君饮，系马高楼垂柳边。这篇文章主要讲述Android 开发 重写定位器类Timer与TimerTask相关的知识，希望能为你提供帮助。

class AttendanceTimer extends Timer { private static final int LOCATION = 0x01; private static final int WAIT = 0x02; private static final int START = 0x03; public int mId; private TimerTask mTimerTask; private AttendanceData mAttendanceData; public Handler mHandler; private LocationBean mBean; private int count = 0; public AttendanceTimer(final int id){ L.i("考勤-短定时器初始化中"); this.mId = id; mHandler = new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); switch (msg.what){ case LOCATION: EventBus.post(new Event(EventCode.EVENT_LOCATION_POST_ATTENDANCE)); L.ii(TAG,"考勤-短定时器定位请求"); mHandler.sendEmptyMessageDelayed(WAIT,1000); break; case WAIT: L.i("考勤-短定时器进入等待处理"); if (mBean == null){ count++; mHandler.sendEmptyMessageDelayed(WAIT,1000); L.ii(TAG,"考勤-短定时器定时数据是空再次进入等待处理"); if (count > 5){ //5次后重新发送定位请求 EventBus.post(new Event(EventCode.EVENT_LOCATION_POST_ATTENDANCE)); count = 0; } break; } count = 0; mHandler.sendEmptyMessage(START); break; case START: L.ii(TAG,"考勤-短定时器启动 longitude="+mBean.longitude+" latitude="+mBean.latitude); L.ii(TAG,"考勤-短定时器启动 longitude="+mAttendanceData.longitude+" latitude="+mAttendanceData.latitude+" radius="+mAttendanceData.radius); if (CoordinateUtil.isInCircle(mBean.longitude,mBean.latitude,mAttendanceData.longitude,mAttendanceData.latitude,String.valueOf(mAttendanceData.radius))){ mAttendanceoutApi.dopost(Session.I().getToken(),String.valueOf(mId),String.valueOf(System.currentTimeMillis())); mBufferId = mId; mBufferTime = System.currentTimeMillis(); L.ii(TAG,"考勤-判断考勤触发，上报考勤 id="+mId); destroy(); mBean = null; break; } L.ii(TAG,"考勤-没有进入考勤位置，创建并且等待下一次判断"); mBean = null; mTimerTask.cancel(); mTimerTask = null; initTimerTask(); purge(); schedule(mTimerTask,30*1000); break; default: break; } } }; initData(); initTimerTask(); schedule(mTimerTask,1*1000); }private void initData(){ mAttendanceData = https://www.songbingjia.com/android/DataBaseSession.I().getIsIdAttenanceData(mId); }private void initTimerTask(){ mTimerTask = new TimerTask() { @Override public void run() { mHandler.sendEmptyMessage(LOCATION); } }; }public void destroy(){ cancel(); purge(); if (mTimerTask != null){ mTimerTask.cancel(); mTimerTask = null; } if(mHandler != null){ mHandler.removeCallbacksAndMessages(null); mHandler = null; }}public void setBean(LocationBean mBean) { L.i("考勤-短定时器设置定位数据"); this.mBean = mBean; } }
