Spring达成上拉刷新和下拉加载效果,spring下拉

正文实例为大家享用了Spring实现上拉刷新和下拉加载效果,供大家仿效,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')

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 { 

      SViewHolder sViewHolder = (SViewHolder)holder ; 
      Glide.with(context).load(list.get(position)).into(sViewHolder.itemSimageview); 

//      ImageLoader.getInstance().displayImage(list.get(position),sViewHolder.itemSimageview); 

    } 


  } 

  @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{ 
    @BindView(R.id.item_simageview) 
    ImageView itemSimageview; 

    SViewHolder(View view) { 
      super(view); 
      ButterKnife.bind(this, view); 
    } 
  } 
}
