Android 使用MediaPlayer播放网络音频(5)

操作通知栏的按纽时发送广播，自定义NotificationReceiver,并静态注册，在NotificationReceiver中控制音频播放

public class NotificationReceiver extends BroadcastReceiver {
    public static final String ACTION_STATUS_BAR = "com.sktcm.app.doctor.utils.audio.NOTIFICATION_ACTIONS";
    public static final String EXTRA = "extra";
    public static final String EXTRA_PLAY = "play_pause";
    public static final String EXTRA_NEXT= "play_next";
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent == null || TextUtils.isEmpty(intent.getAction())) {
            return;
        }
        String extra = intent.getStringExtra(EXTRA);
        if (EXTRA_PLAY.equals(extra)) {
            if (AudioPlayer.getInstance().getStatus() == ManagedMediaPlayer.Status.STARTED) {
                AudioPlayer.getInstance().pause();
            } else if (AudioPlayer.getInstance().getStatus() == ManagedMediaPlayer.Status.PAUSED){
                AudioPlayer.getInstance().resume();
            }
        } else if (EXTRA_NEXT.equals(extra)){
            AudioPlayer.getInstance().next();
        }
    }
}

使用前台服务开始播放音频

public class PlayerService extends Service {
    private static String ACTION_START = "ACTION_START";
    private static String ACTION_PREVIOUS = "ACTION_PREVIOUS";
    private static String ACTION_NEXT = "ACTION_NEXT";
    private static String ACTION_GONE = "ACTION_GONE";
    private static String ACTION_STOP = "ACTION_STOP";
    public static void startPlayerService() {
        Intent intent = new Intent(MyApplication.getContext(), PlayerService.class);
        intent.setAction(ACTION_START);
        MyApplication.getContext().startService(intent);
    }
    public static void playerPreviousService() {
        Intent intent = new Intent(MyApplication.getContext(), PlayerService.class);
        intent.setAction(ACTION_PREVIOUS);
        MyApplication.getContext().startService(intent);
    }
    public static void playerNextService() {
        Intent intent = new Intent(MyApplication.getContext(), PlayerService.class);
        intent.setAction(ACTION_NEXT);
        MyApplication.getContext().startService(intent);
    }
    public static void stopPlayerService() {
        Intent intent = new Intent(MyApplication.getContext(), PlayerService.class);
        MyApplication.getContext().stopService(intent);
    }
    @Override
    public void onCreate() {
        super.onCreate();
        // 开始前台服务
        Notifier.getInstance().init(this);
    }
    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        if (intent != null && intent.getAction() != null) {
            if (ACTION_START.equals(intent.getAction())) {
                AudioPlayer.getInstance().play ();
            } else if (ACTION_PREVIOUS.equals(intent.getAction())) {
                AudioPlayer.getInstance().previous();
            } else if (ACTION_NEXT.equals(intent.getAction())) {
                AudioPlayer.getInstance().next();
            }
        }
        return START_NOT_STICKY;
    }
    @Override
    public void onDestroy() {
        super.onDestroy();
        AudioPlayer.getInstance().release();
        Notifier.getInstance().stopForeground();
    }
}

传入播放列表，并开始服务即可播放
