来自android自带的music源码,下面是广播接收的代码,通过发送广播来控制音乐的播放,停止等

代码如下:

复制代码 代码如下:

     public static final String PLAYSTATE_CHANGED = "com.android.music.playstatechanged";
    public static final String META_CHANGED = "com.android.music.metachanged";
    public static final String QUEUE_CHANGED = "com.android.music.queuechanged";
    public static final String PLAYBACK_COMPLETE = "com.android.music.playbackcomplete";
    public static final String ASYNC_OPEN_COMPLETE = "com.android.music.asyncopencomplete";
    public static final String SERVICECMD = "com.android.music.musicservicecommand";
    public static final String CMDNAME = "command";
    public static final String CMDTOGGLEPAUSE = "togglepause";
    public static final String CMDSTOP = "stop";
    public static final String CMDPAUSE = "pause";
    public static final String CMDPREVIOUS = "previous";
    public static final String CMDNEXT = "next";


   private BroadcastReceiver mIntentReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            String cmd = intent.getStringExtra("command");
            if (CMDNEXT.equals(cmd) || NEXT_ACTION.equals(action)) {
                next(true);
            } else if (CMDPREVIOUS.equals(cmd) || PREVIOUS_ACTION.equals(action)) {
                prev();
            } else if (CMDTOGGLEPAUSE.equals(cmd) || TOGGLEPAUSE_ACTION.equals(action)) {
                if (isPlaying()) {
                    pause();
                } else {
                    play();
                }
            } else if (CMDPAUSE.equals(cmd) || PAUSE_ACTION.equals(action)) {
                pause();
            } else if (CMDSTOP.equals(cmd)) {
                pause();
                seek(0);
            } else if (MediaAppWidgetProvider.CMDAPPWIDGETUPDATE.equals(cmd)) {
                // Someone asked us to refresh a set of specific widgets, probably
                // because they were just added.
                int[] appWidgetIds = intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS);
                mAppWidgetProvider.performUpdate(MediaPlaybackService.this, appWidgetIds);
            }
        }
    };


通过分析可以得出要暂停音乐可以有两种方法,一种是直接发送cmd,另外一种是发送action。

如下暂停音乐播放代码:

复制代码 代码如下:

 private void pauseMusic() {
  Intent freshIntent = new Intent();
  freshIntent.setAction("com.android.music.musicservicecommand.pause");
  freshIntent.putExtra("command", "pause");
  sendBroadcast(freshIntent);
 }
