Android:メディアキーメッセージ

具体的な使用方法:

AudioManagerオブジェクトでMediaoButtonRecevieを登録し、MEDIA_にします.BUTTON.

  audioManager = context.getSystemService(Context.AUDIO_SERVICE) as AudioManager
  audioManager!!.registerMediaButtonEventReceiver(ComponentName(context,MusicIntentReceiver::class.java!!))

放送はAndroidManifestでなければなりません.xmlファイルで宣言しないと、MEDIA_が傍受されません.BUTTONで放送されました.

MusicInentReceiverクラスの作成

    class MusicIntentReceiver : BroadcastReceiver() {
        override fun onReceive(context: Context, intent: Intent) {
            LogManager.info("onReceive" + intent.action)
            if (intent.action == android.media.AudioManager.ACTION_AUDIO_BECOMING_NOISY) {
            } else if (intent.action == Intent.ACTION_MEDIA_BUTTON) {
                val keyEvent = intent.extras!!.get(Intent.EXTRA_KEY_EVENT) as KeyEvent
                LogManager.info("action:" + intent.action + "    keycode:" + keyEvent.keyCode)
                when (keyEvent.keyCode) {
                    KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE -> {
                    
                    }
                    KeyEvent.KEYCODE_MEDIA_PLAY -> {

                    }
                    KeyEvent.KEYCODE_MEDIA_PAUSE -> {
                      
                    }

                    KeyEvent.KEYCODE_MEDIA_STOP -> {
                     
                    }
                    KeyEvent.KEYCODE_MEDIA_NEXT -> {
                  
                    }
                    KeyEvent.KEYCODE_MEDIA_PREVIOUS -> {
                 
                    }
                }
            }
    }
