##Gradle Dependency
Add this in your root build.gradle file (not your module build.gradle file):
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Then, add the library to your module build.gradle
dependencies {
compile 'com.github.jaychou2012:SmartRecyclerView:1.01'
}

##基本用法：
布局文件
<com.whatjay.recyclerview.view.SmartRecyclerview
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerview.setLayoutManager(linearLayoutManager);
recyclerview.setLoadingListener(this);
list = new ArrayList<String>();
mainAdapter = new MainAdapter(this, list);
recyclerview.setAdapter(mainAdapter);
mainAdapter.setOnItemClickListener(this);
mainAdapter.setOnItemLongClickListener(this);
如果想自动刷新的话
recyclerview.refresh();
监听刷新，可以实现接口
implements SmartRecyclerview.LoadingListener
然后实现重写2个方法
@Override
public void onRefresh() {
}
@Override
public void onLoadMore() {
}
刷新完成，要使用
recyclerview.refreshComplete();
加载更多完成，要使用
recyclerview.loadMoreComplete();
没有更多数据了，要使用
recyclerview.setNoMore(true);
可以自己设置更改刷新和加载更多的样式
recyclerview.setRefreshProgressStyle(ProgressStyle.BallBeat);
recyclerview.setLoadingMoreProgressStyle(ProgressStyle.BallClipRotate);
可以自己设置更改刷新的箭头，不设置的话为默认
recyclerview.setArrowImageView(R.mipmap.ic_pulltorefresh_arrow);
Item点击和长按事件使用
implements BaseSmartAdapter.OnRecyclerViewItemClickListener, BaseSmartAdapter.OnRecyclerViewItemLongClickListener
...
@Override
public void onItemClick(View view, int position) {
}
@Override
public void onItemLongClick(View view, int position) {
}
当然，RecyclerView的Adapter写起来很麻烦，并且默认没有点击和长按事件，所以，SmartRecyclerView写好了BaseSmartAdapter和多种布局的BaseMultiSmartAdapter。只需要继承实现就可以了。例如
public class MainAdapter extends BaseSmartAdapter<String> {
public MainAdapter(Context context, List<String> lists) {
super(context, me.zuichu.smartrecyclerviewdemo.R.layout.item_main, lists);
}
@Override
public void bindData(SmarViewHolder holder, String s) {
holder.setText(me.zuichu.smartrecyclerviewdemo.R.id.tv_text, s);
}
}
多种布局的话，用BaseMultiSmartAdapter
public class MultiAdapter extends BaseMultiSmartAdapter<MultiItem> {
public MultiAdapter(Context context, List<MultiItem> data) {
super(context, data);
addItemType(0, R.layout.item_multi1);
addItemType(1, R.layout.item_multi2);
}
@Override
protected void bindData(SmarViewHolder smarViewHolder, MultiItem item) {
switch (item.getItemType()) {
case 0:
smarViewHolder.setText(R.id.tv_text1, "布局一："+item.getName());
break;
case 1:
smarViewHolder.setText(R.id.tv_text2, "布局二："+item.getName());
break;
}
}
}
多种布局的Item实体类要继承SmartMultiEntity
public class MultiItem extends SmartMultiEntity {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
如果你用了GridLayoutManager,又要实现不规则的布局Adapter的话，可以在Adapter里这样写，重写Adapter的onAttachedToRecyclerView方法，然后按照需求判断就可以了
@Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
RecyclerView.LayoutManager manager = recyclerView.getLayoutManager();
if (manager instanceof GridLayoutManager) {
final GridLayoutManager gridManager = ((GridLayoutManager) manager);
gridManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
@Override
public int getSpanSize(int position) {
int position2 = position;
if (position2 >= getLists().size()) {
position2 = getLists().size() - 1;
}
if (getLists().size() > 0) {
int type = getLists().get(position2).getItemType();
return (type == 0) ?
gridManager.getSpanCount() : 1;
}
return gridManager.getSpanCount();
}
});
}
}
SmarRecyclerView轻松帮你实现了下拉刷新，上拉加载更多的逻辑。并且帮你做了很多Adapter里做的事情，简化你的操作。只需继承BaseSmartAdapter或BaseMultiSmartAdapter，实现里面的bindData方法即可，无需自己还要复杂的绑定Item布局，直接帮你自动绑定和加载。赋值的话可以这样用
@Override
public void bindData(SmarViewHolder holder, String s) {
holder.setText(me.zuichu.smartrecyclerviewdemo.R.id.tv_text, s);
}
