Service (2) - started service

startService 구현

  

1. Service 구현

	public class PhService extends Service
	{
	MediaPlayer mMediaPlayer;
	@Override
	public void onCreate() {
	super.onCreate();
	mMediaPlayer = MediaPlayer.create(this, R.raw.sample);
	mMediaPlayer.setLooping(false);
	}
	@Override
	public int onStartCommand(Intent a_intent, int a_flags, int a_startId) {
	final int result = super.onStartCommand(a_intent, a_flags, a_startId);
	mMediaPlayer.start();
	return result;
	}
	@Override
	public void onDestroy() {
	super.onDestroy();
	mMediaPlayer.stop();
	}
	@Override
	public IBinder onBind(Intent intent) {
	return null;
	}
	}

	<manifest xmlns:android="http://schemas.android.com/apk/res/android"
	package="com.parkho.servicesample">
	<application
	android:icon="@mipmap/ic_launcher"
	android:label="@string/app_name"

3. Layout 생성

	<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	android:orientation="vertical">
	<Button
	android:id="@+id/btn_start"
	android:layout_width="match_parent"
	android:layout_height="wrap_content"
	android:layout_margin="24.00dp"
	android:text="@string/start_service" />
	<Button
	android:id="@+id/btn_stop"
	android:layout_width="match_parent"
	android:layout_height="wrap_content"
	android:layout_margin="24.00dp"
	android:text="@string/stop_service" />
	</LinearLayout>

4. MainActivity

	public class PhMainActivity extends AppCompatActivity
	{
	@Override
	protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.activity_main);
	// 서비스 시작
	Button btnStart = findViewById(R.id.btn_start);
	btnStart.setOnClickListener(new OnClickListener() {
	public void onClick(View v) {
	Intent intent = new Intent(getApplicationContext(), PhService.class);
	startService(intent);
	}
	});
	// 서비스 종료
	Button btnStop = findViewById(R.id.btn_stop);
	btnStop.setOnClickListener(new OnClickListener() {
	public void onClick(View v) {
	Intent intent = new Intent(getApplicationContext(), PhService.class);
	stopService(intent);
	}
	});
	}
	}
