UltimateRecyclerView是一个比RecyclerView还全面的类，具体的使用标识如下:
/**

public class MainActivity extends AppCompatActivity {
UltimateRecyclerView ultimateRecyclerView;

LinearLayoutManager linearLayoutManager;
ItemTouchHelper itemTouchHelper;

final List stringList = new ArrayList<>();
stringList.add("111");

//设置布局的格式
ultimateRecyclerView.setLayoutManager(linearLayoutManager);
ultimateRecyclerView.setAdapter(myAdapter);
//给每一个item设置前置的栏目条，
StickyRecyclerHeadersDecoration headersDecor = new StickyRecyclerHeadersDecoration(myAdapter);
ultimateRecyclerView.addItemDecoration(headersDecor);
//设置可以加载更多,但是经常出错
// ultimateRecyclerView.enableLoadmore();
//设置foot加载的view视图
myAdapter.setCustomLoadMoreView(LayoutInflater.from(this)
.inflate(R.layout.custom_bottom_progressbar, null));
//设置item背景的颜色
ultimateRecyclerView.setRecylerViewBackgroundColor(Color.parseColor("#3a0ff4"));
//编写下拉刷新的监听函数

//设置之后item内部的元素可以被拖动
ItemTouchHelper.Callback callback = new SimpleItemTouchHelperCallback(myAdapter);

//设置刷新控件的颜色组成

//设置滑动监听
ultimateRecyclerView.setScrollViewCallbacks(new ObservableScrollViewCallbacks() {
@Override
public void onScrollChanged(int scrollY, boolean firstScroll, boolean dragging) {
Toast.makeText(MainActivity.this, "sc", Toast.LENGTH_SHORT).show();
}
@Override

}
//在这里设置toolbar的隐藏和出现
@Override

//利用一个spinner进行展示各种item进入和删除的动画效果

适配器Adapter文件如下:
public class MyAdapter extends UltimateViewAdapter {
List strs;
public MyAdapter(List strs){
this.strs=strs;
}
public void setOnDragStartListener(OnStartDragListener dragStartListener) {
mDragStartListener = dragStartListener;
}
@Override
public MyAdapterViewHolder getViewHolder(View view) {
return new MyAdapterViewHolder(view);
}
@Override
public MyAdapterViewHolder onCreateViewHolder(ViewGroup parent) {
View v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.recycler_view_adapter, parent, false);
MyAdapterViewHolder vh = new MyAdapterViewHolder(v);
return vh;
}
public void insert(String string, int position) {
insertInternal(strs, string, position);
}
public void remove(int position) {
removeInternal(strs, position);
}
@Override
public int getAdapterItemCount() {
return strs.size();
}
@Override
public void toggleSelection(int pos) {
super.toggleSelection(pos);
}
@Override
public void setSelected(int pos) {
super.setSelected(pos);
}
@Override
public long generateHeaderId(int position) {
if (getItem(position).length() > 0)
return getItem(position).charAt(0);
else return -1;
}
@Override
public void onBindViewHolder(MyAdapterViewHolder holder, int position) {
Log.v("--->postion",position+"");
holder.textview.setText(strs.get(position));
}
@Override
public RecyclerView.ViewHolder onCreateHeaderViewHolder(ViewGroup parent) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.stick_header_item, parent, false);
return new RecyclerView.ViewHolder(view){};
}
@Override
public void onBindHeaderViewHolder(RecyclerView.ViewHolder holder, int position) {
}
public String getItem(int position) {
if (customHeaderView != null)
position--;
if (position < strs.size())
return strs.get(position);
else return "";
}
public class MyAdapterViewHolder extends UltimateRecyclerviewViewHolder {
TextView textview;
public MyAdapterViewHolder(View itemView) {
super(itemView);
textview= (TextView) itemView.findViewById(R.id.textview);
}
}
}
布局文件如下:
xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
