Question

问题基本上是，当尝试在类中使用RecyclerView时，出现错误“无法解析符号“ RecycleView”

这是我的gradle代码

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class=" w-container">
        <div class="sliderTrack">
            <div class="mySlides grow" onclick="wSlider.focusSlide(this)">

Answer 1

ViewHolder不应扩展RecyclerView，但无论如何您都需要导入语句

您想要

import android.support.v7.widget.RecyclerView.ViewHolder;

public class YourViewHolder extends RecyclerView.ViewHolder {

注意：您已经拥有implementation 'com.android.support:recyclerview-v7:28.0.0'，因此请删除recyclerview-v7:28.0.+'行

无法解析符号“ RecycleView”
