MultiTypeAdapter 复杂的列表视图解决方案

1.集成

implementation 'me.drakeet.multitype:multitype:3.3.0'

2.简单布局示例

使用MultiTypeAdapter 是没有适配器的，我们直接继承 ItemViewBinder这个类，在其中处理布局和数据的填充工作。

public class TitleViewBinder extends ItemViewBinder {

    @NonNull
    @Override
    protected TitleHolder onCreateViewHolder(@NonNull LayoutInflater inflater, @NonNull ViewGroup parent) {
        View view = inflater.inflate(R.layout.adapter_title, parent, false);
        return new TitleHolder(view);
    }

    @Override
    protected void onBindViewHolder(@NonNull TitleHolder titleHolder, @NonNull Title title) {
        titleHolder.textView.setText(title.title);
    }

    public class TitleHolder extends RecyclerView.ViewHolder {
        private final TextView textView;

        public TitleHolder(@NonNull View itemView) {
            super(itemView);
            textView = (TextView)itemView.findViewById(R.id.textView);
        }
    }
}

在使用的activity中编写代码：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mRecyclerView = (RecyclerView)this.findViewById(R.id.recyclerView);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
        mAdapter = new MultiTypeAdapter();
        mAdapter.register(Title.class, new TitleViewBinder()); //注册数据
        mRecyclerView.setAdapter(mAdapter);
        ArrayList
