针对RecyclerView的Adapter 添加了如同ListView的 addHeadView addFootView 滑动底部加载更多等功能
同时为了减少每次都要自己实现RecyclerView的Adapter写很多代码 也有了下面两个Base类 不使用也不影响
-
Gradle 依赖
compile 'com.daemon.library:drecyclerviewadapterlib:1.0.3' -
DBaseRecyclerViewAdapter 是项目中使用Adapter的基类 替换原本继承RecyclerView.Adapter 的写法
-
与DBaseRecyclerViewHolder 配合使用 模拟EasyRecyclerView 写法
-
项目中自定义的Adapater 继承DBaseRecyclerViewAdapter
class MyAdapter extends DBaseRecyclerViewAdapter<String> { public MyAdapter(List<String> mDatas, Context mContext, String type1) { super(mDatas, mContext); } @Override public DBaseRecyclerViewHolder onCreateViewHolder1(ViewGroup parent, int viewType, DBaseRecyclerViewAdapter dBaseRecyclerViewAdapter) { return new MyViewHolder(parent, R.layout.item_icon, this); } } -
ViewHolder继承 DBaseRecyclerViewHolder使用
class MyViewHolder extends DBaseRecyclerViewHolder<String> { public MyViewHolder(View itemView, int item_icon, DBaseRecyclerViewAdapter mDBaseRecyclerViewAdapter) { super(itemView, mDBaseRecyclerViewAdapter); } public MyViewHolder(ViewGroup parent, @LayoutRes int res, DBaseRecyclerViewAdapter mDBaseRecyclerViewAdapter) { super(parent, res, mDBaseRecyclerViewAdapter); } @Override public void setData(String data, int position) { super.setData(data, position); } }
最后 用DRecyclerViewAdapter(Mydapater) 装饰
- 具体相关 操作实现
1 LinearLayoutManager 使用
MyAdapter myAdapter = new MyAdapter(lists, this);
//DRecyclerViewAdapter装饰
dRecyclerViewAdapter = new DRecyclerViewAdapter(myAdapter);
LayoutInflater layoutInflater = getLayoutInflater();
View view = View.inflate(this,R.layout.item_top,null);
//添加都和尾部
dRecyclerViewAdapter.addHeaderView(view);
View view1 = layoutInflater.inflate(R.layout.item_foot, null);
dRecyclerViewAdapter.addFooterView(view1);
linearLayoutManager = new LinearLayoutManager(this);
linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
rcv.setLayoutManager(linearLayoutManager);
rcv.setAdapter(dRecyclerViewAdapter);
2 GridLayoutManager 使用
MyAdapter myAdapter = new MyAdapter(lists, this);
dRecyclerViewAdapter = new DRecyclerViewAdapter(myAdapter);
GridLayoutManager dGridLayoutManager = new GridLayoutManager(this, 2);
//设置列数 自定义SpanSizeLookup控制显示列表
dGridLayoutManager.setSpanSizeLookup(new DSpanSizeLookup(dRecyclerViewAdapter, 2));
rcv.setLayoutManager(dGridLayoutManager);
LayoutInflater layoutInflater = getLayoutInflater();
View view = layoutInflater.inflate(R.layout.item_top, null);
View view2 = layoutInflater.inflate(R.layout.item_top, null);
View view3 = layoutInflater.inflate(R.layout.item_top, null);
dRecyclerViewAdapter.addHeaderView(view);
dRecyclerViewAdapter.addHeaderView(view2);
dRecyclerViewAdapter.addHeaderView(view3);
View view1 = layoutInflater.inflate(R.layout.item_foot, null);
dRecyclerViewAdapter.addFooterView(view1);
rcv.setAdapter(dRecyclerViewAdapter);
3 DStaggeredGridLayoutManager 使用 自定义StaggeredGridLayoutManager
MyAdapter myAdapter = new MyAdapter(lists, this, TYPE3);
dRecyclerViewAdapter = new DRecyclerViewAdapter(myAdapter);
DStaggeredGridLayoutManager dStaggeredGridLayoutManager
=new DStaggeredGridLayoutManager(2,StaggeredGridLayoutManager.VERTICAL);
dStaggeredGridLayoutManager.setSpanSizeLookup(
new DSpanSizeLookup(dRecyclerViewAdapter, dStaggeredGridLayoutManager.getSpanCount()));
rcv.setLayoutManager(dStaggeredGridLayoutManager);
LayoutInflater layoutInflater = getLayoutInflater();
View view = layoutInflater.inflate(R.layout.item_top, null);
dRecyclerViewAdapter.addHeaderView(view);
View view1 = layoutInflater.inflate(R.layout.item_foot, null);
dRecyclerViewAdapter.addFooterView(view1);
rcv.setAdapter(dRecyclerViewAdapter);
加载更多
rcv.addOnScrollListener(new DRecyclerViewScrollListener() {
@Override
public void onLoadNextPage(RecyclerView view) {
//显示底部加载样式 分页加载 最后一页 改变footview里面的显示文本
footView.setVisibility(View.VISIBLE);
}
});
