多布局效果图

使用

jitpack对开源分享真是友好啊

Step 1.Add it in your root build.gradle at the end of repositories:
    allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }
Step 2. Add the dependency
    dependencies {
            implementation 'com.github.PMMKing:MultiAdapter:1.1'
    }

直接上代码，简单粗暴

        RecyclerView rlvTest = findViewById(R.id.rlv_test);

        rlvTest.setLayoutManager(new LinearLayoutManager(this));
        MultiAdapter<Integer> adapter = new MultiAdapter<Integer>(this).addTypeView(new ITypeView<Integer>() {
            @Override
            public boolean isForViewType(Integer item, int position) {
                return position % 2 == 0;
            }

            @Override
            public BaseViewHolder createViewHolder(Context mContext, ViewGroup parent) {
                return new ViewHolderOne(mContext, LayoutInflater.from(mContext).inflate(R.layout.item_layout, parent, false));
            }
        }).addTypeView(new ITypeView<Integer>() {
            @Override
            public boolean isForViewType(Integer item, int position) {
                return position % 2 != 0;
            }

            @Override
            public BaseViewHolder createViewHolder(Context mContext, ViewGroup parent) {
                return new ViewHolderTwo(mContext, LayoutInflater.from(mContext).inflate(R.layout.item2_layout, parent, false));
            }
        });
        rlvTest.setAdapter(adapter);
        adapter.setOnItemClickListener(new OnItemClickListener<Integer>() {
            @Override
            public void onItemClickListener(View view, Integer data, int position) {
                Toast.makeText(MainActivity.this, "onClick position is " + position + "   data is " + data, Toast.LENGTH_SHORT).show();
            }
        });
        adapter.setOnLongItemClickListener(new OnItemLongClickListener<Integer>() {
            @Override
            public boolean onItemLongClickListener(View view, Integer data, int position) {
                Toast.makeText(MainActivity.this, "onLongClick position is " + position + "   data is " + data, Toast.LENGTH_SHORT).show();
                return true;
            }
        });
        ArrayList<Integer> list = new ArrayList<>();
        Random rand = new Random();
        while (true) {
            list.add(rand.nextInt());
            if (list.size() > 30) {
                break;
            }
        }
        adapter.setData(list);

添加点击和长按事件，每多一个布局在adapter后面添加一个addTypeView() 方法，方法里面实现一个ITypeView的实例，复写ITypeView的两个方法，第一个判断当前item要显示那个布局文件，第二个返回一个ViewHolder。

ViewHolder继承BaseViewHolder

public class ViewHolderOne extends BaseViewHolder<Integer> {


    private final TextView tvItem;

    public ViewHolderOne(Context context, View itemView) {
        super(context, itemView);
        tvItem = itemView.findViewById(R.id.tv_item);
    }

    @Override
    public void onBindViewHolder(BaseViewHolder holder, Integer data, int position) {
        tvItem.setText("布局1的item的position是：" + position + "    data是：" + data);
    }
}

不想讲代码，感兴趣的自己看吧，这个库自己已经用了一段时间了，上拉加载，下拉刷新来了，
