Service使用
Service相关成员变量
TimerService mLocalService;ServiceConnection mSc = new ServiceConnection(){@Overridepublic void onServiceConnected(ComponentName name,IBinder binder){mLocalService = ((TimerService.LocalBinder)binder).getService();}@Overridepublic void onServiceDisconnected(ComponentName name){mLocalService = null;}}; 绑定Service
Intent service = new Intent(this.getApplicationContext(),TimerService.class);this.bindService(service, mSc, Context.BIND_AUTO_CREATE);
BroadcastReceiver使用
BroadcastReceiver相关成员变量
public final static String ACTION_TIME_UPDATE = "update";public final static String ACTION_TIMER_FINISHED = "finished";private BroadcastReceiver mTimerReceiver = new BroadcastReceiver(){@Overridepublic void onReceive(Context context,Intent intent){if( intent.getAction().equals(ACTION_TIME_UPDATE) ){Long time = intent.getLongExtra("time", 0) / 1000;TextView counter = (TextView) findViewById(R.id.counter);counter.setText(DateUtils.formatElapsedTime(time));}else if( intent.getAction().equals(ACTION_TIMER_FINISHED) ){Long time = intent.getLongExtra("time", 0);CounterUpdate(0);Log.i("TEST","get finished");mTimeListAdapter.add(time/1000);}}};
BroadcastReceiver注册
IntentFilter filter = new IntentFilter();filter.addAction(ACTION_TIME_UPDATE);filter.addAction(ACTION_TIMER_FINISHED);registerReceiver(mTimerReceiver,filter);
