1.MainActivity.java

public void onClick(View v) {Intent intent = new Intent(this,MusicService.class);switch (v.getId()) {case R.id.btn_main_play://播放intent.putExtra("action", "play");startService(intent);break;case R.id.btn_main_stop://停止播放intent.putExtra("action", "stop");startService(intent);break;case R.id.btn_main_pause://暂停音乐intent.putExtra("action", "pause");startService(intent);break;case R.id.btn_main_exit://退出并停止音乐//停止服务stopService(intent);finish();break;default:break;}}

package com.example.servicemusic;import android.app.Service;import android.content.Intent;import android.media.MediaPlayer;import android.os.IBinder;/** * 播放音乐的Service * @author Xiaocici * */public class MusicService extends Service {@Overridepublic IBinder onBind(Intent intent) {// TODO Auto-generated method stubreturn null;}private MediaPlayer player;@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {String action = intent.getStringExtra("action");if("play".equals(action)){playMusic();}else if("pause".equals(action)){pauseMusic();} else if("stop".equals(action)){stopMusic();} return super.onStartCommand(intent, flags, startId);}@Overridepublic void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();//在死亡之前停止音乐stopMusic();}/* * 播放音乐 */private void playMusic() {if(player==null){player = MediaPlayer.create(this, R.raw.brave_love);//音乐名不能为汉字}player.start();}/* * 暂停音乐 */private void pauseMusic() {if(player!=null&&player.isPlaying()){player.pause();}}private void stopMusic() {if(player!=null){player.stop();//停止player.reset();//重置player.release();//释放资源player = null;//赋空}}}
