Android之Service应用实例

核心提示：public class MyActivity extends Activity {private MyService mService;private static boolean ISRUNNING = false;@Overridepublic void onCreate(Bundle savedInstance

public class MyActivity extends Activity {

private MyService mService;

private static boolean ISRUNNING = false;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

startMyService();// 启动

}

@Override

}

private ServiceConnection mConnection = new ServiceConnection() {

@Override

public void onServiceConnected(ComponentName name, IBinder service) {

// TODO Auto-generated method stub

mService =

((MyService.MyBinder)service).getServices();

}

@Override

public void onServiceDisconnected(ComponentName name) {

// TODO Auto-generated method stub

}

};

Intent intent = new Intent(MyActivity.this, MyService.class);

// 启动服务

private void startMyService() {

startService(intent);

ISRUNNING = true;

}

// 绑定

private void bindMyService() {

bindService(intent, mConnection,Context.BIND_AUTO_CREATE);

}

// 取消绑定

private void unbindMyService() {

unbindService(mConnection);

}

private void stopMyService() {

stopService(intent);

ISRUNNING = false;

}

}

上述代码展示了一个Activity(Client)如何启动并绑定一个服务的。主要是利用了Activity的生命周期来创建、绑定、取消绑定一个服务。

上面代码中没有没用调用stopMyService()退出个服务，可根据你的需要进行调用。
