支持下拉刷新和自定义加载更多的RecycleView

PowerRecyclerView使用

//gradle
compile 'com.lovejjfg.powerrecycle:powerrecycle:1.0.1'

V1.0.0

实现下拉刷新加载更多

V1.0.1

加载更多适配GridLayoutManager

添加单选和多选模式

---

0、创建：（Adapter 继承 RefreshRecycleAdapter）

    mRecycleView.setLayoutManager(new LinearLayoutManager(this));
    mRecycleView.setAdapter(adapter);
    mRecycleView.setOnRefreshListener(this);
    adapter = new MyRecycleAdapter();
    adapter.setLoadMoreListener(this);
    adapter.setTotalCount(10);

1、创建自己对应的布局的方法：

RecyclerView.ViewHolder onViewHolderCreate(ViewGroup parent, int viewType);

void onViewHolderBind(RecyclerView.ViewHolder holder, int position);

2、加载更多的几种状态的更改：

boolean isHasMore();//是否还有更多，可以自己实现具体的逻辑！

void isLoadingMore();

void loadMoreError();

3、自定义加载更多的布局：

void setLoadMoreView(View view);

RecyclerView.ViewHolder onBottomViewHolderCreate(View loadMore);

void onBottomViewHolderBind(RecyclerView.ViewHolder holder, int loadState);

4、添加数据源相关的方法，提供了set和append两种方式：

void setList(List<T> data);

void appendList(List<T> data);

@Override
public final void appendList(List<T> data) {
    int positionStart = list.size();
    list.addAll(data);
    int itemCount = list.size() - positionStart;

    if (positionStart == 0) {
        notifyDataSetChanged();
    } else {
        notifyItemRangeInserted(positionStart + 1, itemCount);
    }
}

5、选择模式，及相关回调：

adapter.setSelectedMode(AdapterLoader.SingleMode);
adapter.updateSelectMode(true);
adapter.setOnItemSelectListener(new AdapterLoader.OnItemSelectedListener() {
    @Override
    public void onItemSelected(View view, int position, boolean isSelected) {
        Log.e("TAG", "onItemSelected: " + position + "::" + isSelected);
    }

    @Override
    public void onNothingSelected() {
        Log.e("TAG", "onNothingSelected: ");
    }
});

6、GridLayoutManager设置SpanSize

    mRecycleView.setSpanSizeCallBack(new SwipeRefreshRecycleView.SpanSizeCallBack() {
        @Override
        public int getSpanSize(int position) {
            return 1;
        }
    });

7、使用SpacesItemDecoration添加上下左右留白

/**
 *
 * @param space item之间的空间
 * @param count 列数
 * @param showEdge 是否显示左右边缘
 */
public SpacesItemDecoration(int space, int count, boolean showEdge) {
    this.spacing = space;
    this.spanCount = count;
    this.showEdge = showEdge;
    pre = spacing * 1.0f / spanCount;
}

decor = new SpacesItemDecoration(30, 3, true);
mRecycleView.getRecycle().addItemDecoration(decor);
