Android Kotlin 使用 BaseRecyclerViewAdapterHelper 实现 RecyclerView 展开收起效果

要在Android Kotlin中使用BaseRecyclerViewAdapterHelper库的ExpandableTextView实现展开收起效果，可以按照以下步骤进行操作：\n\n1. 在项目的build.gradle文件中添加BaseRecyclerViewAdapterHelper库的依赖：\n\ngroovy\nimplementation 'com.github.CymChad:BaseRecyclerViewAdapterHelper:3.0.10'\n\n\n2. 在RecyclerView的布局文件中添加ExpandableTextView控件：\n\nxml\n<com.chad.library.adapter.base.viewholder.BaseViewHolder\n ...\n <com.chad.library.adapter.base.view.ExpandableTextView\n android:id="@+id/expandable_text"\n android:layout_width="match_parent"\n android:layout_height="wrap_content"\n app:etv_animation_duration="200"\n app:etv_collapse_text="收起"\n app:etv_expand_text="展开"\n app:etv_max_lines="3"\n app:etv_text="这是一段需要展开收起的文本"\n app:etv_text_color="@color/black"\n app:etv_text_size="14sp" />\n ...\n</com.chad.library.adapter.base.viewholder.BaseViewHolder>\n\n\n3. 在RecyclerView的Adapter中处理ExpandableTextView的展开收起逻辑：\n\nkotlin\nclass MyAdapter(data: List<String>) : BaseQuickAdapter<String, BaseViewHolder>(R.layout.item_layout, data) {\n\n override fun convert(holder: BaseViewHolder, item: String) {\n val expandableTextView = holder.getView<ExpandableTextView>(R.id.expandable_text)\n \n // 设置展开收起监听器\n expandableTextView.setOnExpandStateChangeListener(object : ExpandableTextView.OnExpandStateChangeListener {\n override fun onExpandStateChanged(isExpanded: Boolean) {\n // 展开收起状态改变时的逻辑处理\n }\n })\n \n // 设置展开收起文本的点击监听器\n expandableTextView.setOnExpandClickListener(object : ExpandableTextView.OnExpandClickListener {\n override fun onExpandClick() {\n // 点击展开收起文本时的逻辑处理\n }\n })\n \n // 设置展开收起文本的最大行数\n expandableTextView.maxLines = 3\n \n // 设置展开收起文本的内容\n expandableTextView.text = item\n }\n}\n\n\n通过以上步骤，你可以在Android Kotlin中使用BaseRecyclerViewAdapterHelper库的ExpandableTextView实现展开收起效果。你可以根据需要在Adapter的convert方法中进行展开收起状态改变和点击事件的逻辑处理。
