RecyclerView 加載多種Item佈局

須要在Adapter適配器中設置

使用getItemViewType()方法設置根據不一樣ID來判斷設置佈局

public class Adapter extends RecyclerView.Adapter<Adapter.MyHolder> {
    private Context context;
    private List<Bean> list;

    public Adapter(Context context, List<Bean> list) {
        this.context = context;
        this.list = list;
    }
    /**
     * recyclerView 加載多佈局方法步驟
     * 1. 建兩個不一樣的佈局
     * 2. 思路：要提供一個不一樣的標準，標註  程序選擇不一樣的佈局
     */
    @Override
    public int getItemViewType(int position) {
        return list.get(position).getName().contains("2")==true?0:1;
    }
    /**
     * 實例化一個佈局
     * @param parent
     * @param viewType <----getItemviewType
     * @return
     */
    @Override
    public Adapter.MyHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        MyHolder myHolder = null;
        switch (viewType){
            case 0:
                View inflate = LayoutInflater.from(context).inflate(R.layout.layout, null);
                myHolder = new MyHolder(inflate);
                break;
            case 1:
                View inflate1 = LayoutInflater.from(context).inflate(R.layout.layout1, null);
                myHolder = new MyHolder(inflate1);
                break;
        }
        return myHolder;
    }

    @Override
    public void onBindViewHolder(Adapter.MyHolder holder, int position) {
        holder.img.setImageResource(list.get(position).getImg());
        holder.name.setText(list.get(position).getName());
        holder.text.setText(list.get(position).getText());
    }

    @Override
    public int getItemCount() {
        return list.size();
    }

    /**
     * 各類佈局，進行重用的view
     */
    public class MyHolder extends RecyclerView.ViewHolder {
        private final ImageView img;
        private final TextView name;
        private final TextView text;
        public MyHolder(View itemView) {
            super(itemView);
            img = itemView.findViewById(R.id.img);
            name = itemView.findViewById(R.id.name);
            text = itemView.findViewById(R.id.text);
        }
    }
}
