如何处理耳机挂钩的双击？

Question

我只想通过一个耳机按钮来控制壁球得分计数器应用程序。这意味着我要检测单击或双击，并根据点击数向第一或第二名玩家添加得分。

我不能使用长按来代替双击，因为长按会激活Google即时。

Answer 1

这是我在音乐播放器中用来处理耳机控制的双击操作。

static final long CLICK_DELAY = 500;
static long lastClick = 0; // oldValue
static long currentClick = System.currentTimeMillis();

@Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_MEDIA_BUTTON)) {

            KeyEvent keyEvent = (KeyEvent) intent.getExtras().get(Intent.EXTRA_KEY_EVENT);

            if (keyEvent.getAction() != KeyEvent.ACTION_DOWN)return;

            lastClick = currentClick ;

            currentClick = System.currentTimeMillis();

            if(currentClick - lastClick < CLICK_DELAY ){

                 //This is double click

            } else { 

                 //This is single click

            }
        }

为时已晚，但也许有人会发现它有用，例如Google音乐，Spotify等三连击。>

const val DOUBLE_CLICK_TIMEOUT = 430L
private var mHeadsetHookClickCounter = 0

override fun onMediaButtonEvent(mediaButtonEvent: Intent?): Boolean {


    if (Intent.ACTION_MEDIA_BUTTON == mediaButtonEvent?.action) {

        val ke = mediaButtonEvent.getParcelableExtra<KeyEvent>(Intent.EXTRA_KEY_EVENT)

        if (ke != null && ke.keyCode == KeyEvent.KEYCODE_HEADSETHOOK) {

            if (ke.action == KeyEvent.ACTION_UP) {

                mHeadsetHookClickCounter = min(mHeadsetHookClickCounter+1, 3)

                if (mHeadsetHookClickCounter == 3) {
                    handlingHeadsetClick()
                } else {


                    Handler().postDelayed({

                        handlingHeadsetClick()

                    },  DOUBLE_CLICK_TIMEOUT)

                }


            }

            return true
        }
    }
    return super.onMediaButtonEvent(mediaButtonEvent)
}


private fun handlingHeadsetClick() {

    logd("MediaSessionSupportFeature Handling headset click")

    when(mHeadsetHookClickCounter) {

        1 -> { service.get()?.togglePlayPause() }
        2 -> { service.get()?.playNext() }
        3 -> { service.get()?.playPrevious() }

    }

    // Reset Counter
    mHeadsetHookClickCounter = 0 


    return

}
