如何在Oreo中为媒体按钮注册广播接收器？

<receiver android:name=".MediaButtonReceiver">
    <intent-filter>
        <action android:name="android.intent.action.MEDIA_BUTTON" />
    </intent-filter>
</receiver>

@Override
public void onReceive(Context context, Intent intent) {
    if (Intent.ACTION_MEDIA_BUTTON.equals(intent.getAction())) {
        KeyEvent event = intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
        if (event != null && event.getAction() == KeyEvent.ACTION_DOWN) {
            // 处理媒体按钮按下事件
        }
    }
}
