Spring实现上拉刷新和下拉加载效果

本文实例为大家分享了Spring实现上拉刷新和下拉加载效果，供大家参考，具体内容如下

导依赖:

compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.liaoinstan.springview:library:1.3.0'
compile files('libs/glide-3.7.0.jar')

activity_main布局

下拉布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical">
<ImageView
android:src="@mipmap/ic_launcher"
android:scaleType="centerCrop"
android:id="@+id/item_simageview"
android:layout_width="match_parent"
android:layout_height="100dp" />
</LinearLayout>

刷新布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical">
<ImageView
android:src="@mipmap/ic_launcher"
android:id="@+id/item_simageview"
android:layout_width="match_parent"
android:layout_height="100dp" />
<TextView
android:background="@color/colorPrimary"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/item_stextview"/>
</LinearLayout>

MultiAdapter 适配器 

public class MultiAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private Context context;
private List<String> list;
public MultiAdapter(Context context, List<String> list) {
this.context = context;
this.list = list;
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (viewType == 0) {
View view = LayoutInflater.from(context).inflate(R.layout.layout_fitem,parent, false);
return new FViewHolder(view);
} else {
View view = LayoutInflater.from(context).inflate(R.layout.layout_sitem, parent, false);
return new SViewHolder(view);
}
}
@Override
public int getItemViewType(int position) {
return position % 2 ;
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if(holder instanceof FViewHolder){
FViewHolder fViewHolder = (FViewHolder)holder ;
fViewHolder.itemStextview.setText(position+"");
Glide.with(context).load(list.get(position)).into(fViewHolder.itemSimageview);
//      ImageLoader.getInstance().displayImage(list.get(position),fViewHolder.itemSimageview);
} else {

}
}
@Override
public int getItemCount() {
return list.size();
}
static class FViewHolder extends RecyclerView.ViewHolder{
@BindView(R.id.item_simageview)
ImageView itemSimageview;
@BindView(R.id.item_stextview)
TextView itemStextview;
FViewHolder(View view) {
super(view);
ButterKnife.bind(this, view);
}
}
class SViewHolder extends RecyclerView.ViewHolder{

}
}
