Android开发中定时与延时的运用

private void unceasingDiscovery(){    final Timer mTimer=new Timer();    TimerTask mTimerTask=new TimerTask() {@Overridepublic void run() {// TODO 自动生成的方法存根if(mBluetoothAdapter.isDiscovering())mBluetoothAdapter.cancelDiscovery();elsemBluetoothAdapter.startDiscovery();}};//开始一个定时任务，延时500ms，周期为800msmTimer.schedule(mTimerTask, 500,800);        }
