Android的service學習（1）

首先聲明一個service：

public class myservice extends Service {

@Override

public IBinder onBind(Intent arg0) {

// TODO Auto-generated method stub

return null;

}

@Override

public void onCreate() {

// TODO Auto-generated method stub

super.onCreate();

System.out.println("start");

}

@Override

public void onDestroy() {

// TODO Auto-generated method stub

super.onDestroy();

System.out.println("stop");

}

}

并在Mainfiest中配置：

<service android:name="myservice"></service>

在MainActivity中啟動和停止service：

public class MainActivity extends Activity implements OnClickListener {

private Button start,stop;

private Intent i;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

start=(Button) findViewById(R.id.start);

stop=(Button) findViewById(R.id.stop);

start.setOnClickListener(this);

stop.setOnClickListener(this);

i=new Intent(this,myservice.class);

}

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

switch(v.getId()){

case R.id.start:

startService(i);

break;

case R.id.stop:

stopService(i);

break;

}

}

}
