使用Broadcast控制播放器，新方法…

之前通过Broadcast控制播放器的方法是：

   private void pauseMusic() {

                Intent freshIntent = new Intent();

         freshIntent.setAction("com.android.music.musicservicecommand.pause");

              freshIntent.putExtra("command", "pause");

          sendBroadcast(freshIntent);

      }

经过我测试，无效了。API-18，4.3。

以下是新方法：

AudioManager mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);if(mAudioManager.isMusicActive()) { 

        Intent i = new Intent(SERVICECMD);    i.putExtra(CMDNAME , CMDSTOP ); 

   YourApplicationClass.this.sendBroadcast(i); 

}

以下是命令：

public static final String CMDTOGGLEPAUSE = "togglepause";  

public static final String CMDPAUSE = "pause";  

public static final String CMDPREVIOUS = "previous";  

public static final String CMDNEXT = "next";  

public static final String SERVICECMD = "com.android.music.musicservicecommand";  

public static final String CMDNAME = "command";  

public static final String CMDSTOP = "stop";

===========如果以上还是不行，看下面========================

以下方法适合所有播放器

long eventtime = SystemClock.uptimeMillis(); 

//播放+暂停

Intent downIntent = new Intent(Intent.ACTION_MEDIA_BUTTON, null); 

KeyEvent downEvent = new KeyEvent(eventtime, eventtime, KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE, 0); 

downIntent.putExtra(Intent.EXTRA_KEY_EVENT, downEvent); 

sendOrderedBroadcast(downIntent, null); 

//这个upIntent要和上面的downIntent 一起使用，才能播放或者暂停，只用downIntent 会不停切换下一曲，必须重启手机。

Intent upIntent = new Intent(Intent.ACTION_MEDIA_BUTTON, null); 

KeyEvent upEvent = new KeyEvent(eventtime, eventtime, KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE, 0); 

upIntent.putExtra(Intent.EXTRA_KEY_EVENT, upEvent); 

sendOrderedBroadcast(upIntent, null); 

// 下一曲，跟上面一样，downIntent 和upIntent 要同时用，只用down就变成快进。

Intent downIntent = new Intent(Intent.ACTION_MEDIA_BUTTON, null); 

KeyEvent downEvent = new KeyEvent(eventtime, eventtime, KeyEvent.ACTION_DOWN,   KeyEvent.KEYCODE_MEDIA_NEXT, 0); 

downIntent.putExtra(Intent.EXTRA_KEY_EVENT, downEvent); 

sendOrderedBroadcast(downIntent, null); 

Intent upIntent = new Intent(Intent.ACTION_MEDIA_BUTTON, null); 

KeyEvent upEvent = new KeyEvent(eventtime, eventtime, KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_NEXT, 0); 

upIntent.putExtra(Intent.EXTRA_KEY_EVENT, upEvent); 

sendOrderedBroadcast(upIntent, null); 

//上一曲，只用down就变成快退。

Intent downIntent = new Intent(Intent.ACTION_MEDIA_BUTTON, null); 

KeyEvent downEvent = new KeyEvent(eventtime, eventtime, KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PREVIOUS, 0); 

downIntent.putExtra(Intent.EXTRA_KEY_EVENT, downEvent); 

sendOrderedBroadcast(downIntent, null);

Intent upIntent = new Intent(Intent.ACTION_MEDIA_BUTTON, null); 

KeyEvent upEvent = new KeyEvent(eventtime, eventtime, KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PREVIOUS, 0); 

upIntent.putExtra(Intent.EXTRA_KEY_EVENT, upEvent); 

sendOrderedBroadcast(upIntent, null);
