如何在异步映像加载中使用机器人绑定？

Question

我如何使用机器人绑定的AdapterView与动态图像加载程序，如离子或毕加索？

我从一个REST服务中获得了一个位置列表，其中一个属性是我想在视图中显示的图像的url。

这就是我所拥有的：

@org.robobinding.annotation.PresentationModel
public class LocationAdapterPresentationModel implements HasPresentationModelChangeSupport {
private final PresentationModelChangeSupport changeSupport;
private final Activity activity;
List<Location> locations;

public LocationAdapterPresentationModel(Activity activity, List<Location> locs){
    locations = locs;
    this.changeSupport = new PresentationModelChangeSupport(this);
    this.activity = activity;
}

@ItemPresentationModel(LocationPresentationModel.class)
public List<Location> getLocations(){
    return new ArrayList<Location>(locations);
}

public void refreshLocations() {
    changeSupport.firePropertyChange("locations");
}

public void setLocations(List<Location> locs){
    this.locations = locs;
}

@Override
public PresentationModelChangeSupport getPresentationModelChangeSupport() {
    return changeSupport;
}

}

@org.robobinding.annotation.PresentationModel
public class LocationPresentationModel implements ItemPresentationModel<Location> {

...
my getter / setter 
...
}

但是把动力装载机放在哪里。当它只是一个项目时会很容易，但是如何使它与位置列表中的每个条目一起工作呢？

ItemPresentationModel附带了一个updateData方法，我把所有需要的东西都放进去了。这解决了我的问题。

  @Override
public void updateData(Location location, ItemContext itemContext) { 
      ViewGroup itemView = (ViewGroup) itemContext.getItemView();
    ImageView image1 = (ImageView) itemView.findViewById(R.id.image1);
    ImageView image2 = (ImageView) itemView.findViewById(R.id.image2);

    Ion.with(image1)
            .placeholder(R.drawable.loading)
            .error(R.drawable.emptypicture)
            .animateLoad(R.anim.loading_circle)
            .load(location.getPreviewImg1());
}
