Service（一）

一、Service简单示例：

Service类：

public class DummyService extends Service {

 

    @Override

    public IBinder onBind(Intent arg0) {

       // TODO Auto-generated method stub

       return null;

    }

    @Override

    public void onCreate(){

       super.onCreate();

    }

    @Override

    public void onStart(Intent intent,int startId){

       super.onStart(intent,startId);

       Log.i("Service-start", "服务开始了");

       Toast.makeText(this, "i am server", Toast.LENGTH_LONG).show();

    }

    @Override

    public void onDestroy() {

       // TODO Auto-generated method stub

       

       super.onDestroy();

       Log.i("Service-stop", "服务被销毁了");

    }

    

 

}

Activity类：

public class ServerDemoActivity extends Activity implements OnClickListener{

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        Button btn1=(Button)findViewById(R.id.btn1);

        btn1.setText("this is my activity");

        btn1.setOnClickListener(this);

        Button btn2=(Button)findViewById(R.id.btn2);

        btn2.setOnClickListener(this);

    }

    public void onClick(View v) {

       switch(v.getId()){

       case R.id.btn1:{

           doStart();

           break;

       }

       case R.id.btn2:{

           doStop();

           break;

       }

       }

    }

    public void doStart(){

       Intent starServer=new Intent(this,DummyService.class);

       this.startService(starServer);

    }

    public void doStop(){

       Intent starServer=new Intent(this,DummyService.class);

       this.stopService(starServer);

    }

}
