RecyclerView添加分割线

RecyclerView添加分割线

1. 分割线：

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder>{
    private List<String> list;
    private Context context;

    public MyAdapter(List<String> list, Context context) {
        this.list = list;
        this.context = context;
    }

    public void removeData(int position){
        list.remove(position);
        notifyItemRemoved(position);
    }

    @NonNull
    @Override
    public MyViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        View view=View.inflate(context,R.layout.item,null);
        return new MyViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull MyViewHolder myViewHolder, int i) {
        myViewHolder.textView.setText(list.get(i));
    }

    @Override
    public int getItemCount() {
        return list==null?0:list.size();
    }

    public class MyViewHolder extends RecyclerView.ViewHolder{
        private TextView textView;
        public MyViewHolder(@NonNull View itemView) {
            super(itemView);
            textView=itemView.findViewById(R.id.textview);
        }
    }
}

1. activity中：

recyclerView.addItemDecoration(new DividerItemDecoration(this,DividerItemDecoration.VERTICAL_LIST));
