Android开发中定时与延时的运用

private void unceasingDiscovery(){
final Timer mTimer=new Timer();
TimerTask mTimerTask=new TimerTask() {

@Override
public void run() {
// TODO 自动生成的方法存根
if(mBluetoothAdapter.isDiscovering())
mBluetoothAdapter.cancelDiscovery();
else
mBluetoothAdapter.startDiscovery();
}
};
//开始一个定时任务，延时500ms，周期为800ms
mTimer.schedule(mTimerTask, 500,800);

}
