Java 单击每个recyclerView列表
我在布局中设置了2个recyclerView,并使用arraylist在该recyclerView中传递数据。我试图在不同recyclerview的每个数组列表中设置clickListener 这是适配器 公共类RecyclerAdapter扩展了RecyclerView.Adapter{ 语境; 国际布局; 列出数据; 私有OnNoteClickListener mOnNoteClickListener; 公共回收器适配器(上下文上下文、int-layoutId、列表数据、OnNoteClickListener OnNoteClickListener){ this.context=上下文; LayoutId=LayoutId; 这个数据=数据; this.mOnNoteClickListener=onNoteClickListener; } 公共回收器适配器(主活动主活动,内部项目\布局\垂直,列表顶部回收数据){ } @非空 @凌驾 public RecycleServiceWholder onCreateViewHolder(@NonNull ViewGroup父级,int-viewType){ LayoutInflater充气器=LayoutInflater.from(parent.getContext()); 查看myView=充气机。充气(LayoutId,null); 返回新的RecycleServiceWholder(myView、mOnNoteClickListener); } @凌驾 BindViewHolder上的公共void(@NonNull RecycleServiceWholder holder,int位置){ final ItemModel singleItem=data.get(位置); holder.imgTitle.setText(singleItem.getImgTitle()); holder.img.setImageDrawable(context.getResources().getDrawable(singleItem.getImgId()); } @凌驾 public int getItemCount(){ 返回data.size(); } 公共类RecyclerViewWholder扩展了RecyclerView.ViewHolder实现了View.OnClickListener{ OnNoteClickListener OnNoteClickListener; 文本视图imgTitle; 图像视图img; public RecycleServiceWholder(@NonNull View itemView,OnNoteClickListener OnNoteClickListener){ 超级(项目视图); imgTitle=itemView.findviewbyd(R.id.imgTitle); img=itemView.findviewbyd(R.id.img); this.onNoteClickListener=onNoteClickListener; setOnClickListener(这个); } @凌驾 公共void onClick(视图){ onNoteClickListener.onNoteClick(getAdapterPosition()); } } 公共接口OnNoteClickListener{ void onNoteClick(整数位置); } } 这是显示recyclerview的活动:Java 单击每个recyclerView列表,java,android-studio,android-recyclerview,onclick,Java,Android Studio,Android Recyclerview,Onclick,我在布局中设置了2个recyclerView,并使用arraylist在该recyclerView中传递数据。我试图在不同recyclerview的每个数组列表中设置clickListener 这是适配器 公共类RecyclerAdapter扩展了RecyclerView.Adapter{ 语境; 国际布局; 列出数据; 私有OnNoteClickListener mOnNoteClickListener; 公共回收器适配器(上下文上下文、int-layoutId、列表数据、OnNoteClic

如果只有一个recyclerview,那么我希望我能做到这一点,但这次在一个家里有两个recyclerview和两个不同的arrylist。所以我很困惑如何调用recyclerview的两个不同arraylist的侦听器
我想在第一个回收器视图中单击“例如”位置2时生成toast消息,在第二个回收器视图中单击位置1时生成toast消息。以下是所有更改的完整代码。我已经测试了你的代码,它运行良好 MainActivity Java
