一句話，scroll-view的子元素要inline-block，父元素white-space: nowrap;就可以橫向排列。但是這個時候，子元素有最后一個元素有可能是顯示不全的，需要在scroll-view加上overflow: scroll;。就可以完美解決問題，直接上代碼吧。本人親自踩此坑，如有幫助，請點贊哦，好用不點贊就是耍流氓，哈哈，白嫖。

<view class="title-con">
            <view class="conclude-title">已選</view>
            <scroll-view class="scroll-view_H" scroll-x="true">
                <block wx:for="{{selectedStrategy}}" wx:key="strategy_id">
                    <view class="filter-item">
                        <!-- <text>{{item.strategy_name}}</text> -->
                        {{item.strategy_name}}
                        <image src="/images/close.png" class="close" bindtap="handleCloseStrategy" data-catid="{{item.strategy_cat_id}}" data-strategyid="{{item.strategy_id}}" />
                    </view>
                </block>
            </scroll-view>
        </view>

.title-con {
    display: flex;
    flex-direction: row;
    flex-wrap: nowrap;
    height: 62rpx;
    width: 100%;
    flex-direction: row;
    align-items: center;
    overflow: visible;
    white-space: nowrap;
}

.scroll-view_H {
    width: 100%;
    overflow: scroll;
}

.filter-item {
    padding-left: 28rpx;
    padding-right: 28rpx;
    line-height: 62rpx;
    background: rgba(237, 249, 249, 1);
