调用Service中的方法

一、新建类继承Service

public class DemoService extends Service{//新建内部类public class DemoServiceBinder extends Binder{DemoServiceBinder getService(){return DemoService.this;}}//实例化内部类private final IBinder basBinder = new DemoServiceBinder();//重写绑定方法，返回内部类对象@Overridepublic IBinder onBind(Intent intent){return basBinder;}//要调用的方法public void DemoMethod(){...}}

 

二、Activity类

public class DemoActivity extends Activity{//定义按钮的点击事件public void onClick(View v){//开始并绑定服务startService(serviceIntent);bindService(serviceIntent,conn,Context.BIND_AUTO_CREATE);//通过service调用服务里的方法...//解除绑定并停止服务unbindService(serviceIntent);stopService(serviceIntent);}private DemoService service;//创建Service连接private ServiceConnection conn = new ServiceConnection(){public void onServiceConnected(ComponentName className,IBinder baBinder){service = ((DemoService.DemoServiceBinder)baBinder).getService();}public void onServiceDisconnected(ComponentName className){service = null;}}}
