Fedor 的画廊延迟加载

我正在使用 Fedor 的延迟加载，但我似乎无法调整它来填充图库而不是列表视图。我的主要问题似乎是不必膨胀单独的布局。如何将图像结果直接传递到图库？

这是我当前的 getview，它不起作用

 public View getView(int position, View convertView, ViewGroup parent) {
    View vi=convertView;
    if(convertView==null){
    ImageView image= new ImageView(context);
    image.setLayoutParams(new Gallery.LayoutParams(150, 100));
    image.setScaleType(ImageView.ScaleType.FIT_XY);
    imageLoader.DisplayImage(data[position], activity, image);
  }
    return vi;
  }

，错误是图库中的空指针异常。

关于适当的调整有什么想法吗？

谢谢

I am using Fedor's Lazy Load, but I can't seem to adapt it to populate a gallery instead of a listview. My main problem seems to be to do with not having to inflate a separate layout. How do I pass the image results straight to the gallery?

This is my current getview which doesnt work

 public View getView(int position, View convertView, ViewGroup parent) {
    View vi=convertView;
    if(convertView==null){
    ImageView image= new ImageView(context);
    image.setLayoutParams(new Gallery.LayoutParams(150, 100));
    image.setScaleType(ImageView.ScaleType.FIT_XY);
    imageLoader.DisplayImage(data[position], activity, image);
  }
    return vi;
  }

and the error is a nullpointerexception within the gallery.

Any ideas on the appropriate adaptations?

Thanks

我使用以下方法让它工作：

 public View getView(int position, View convertView, ViewGroup parent) {
    View vi=convertView;
    if(convertView==null){
        vi = inflater.inflate(R.layout.galitem, null);
    ImageView image=(ImageView)vi.findViewById(R.id.galimage);
    imageLoader.DisplayImage(data[position], activity, image);
    }

    return vi;

}

我在其他地方设置了参数。

I got it to work using the following:

 public View getView(int position, View convertView, ViewGroup parent) {
    View vi=convertView;
    if(convertView==null){
        vi = inflater.inflate(R.layout.galitem, null);
    ImageView image=(ImageView)vi.findViewById(R.id.galimage);
    imageLoader.DisplayImage(data[position], activity, image);
    }

    return vi;

}

I set the parameters elsewhere.

试试这个：

public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imgView;
    if (convertView == null) {
        imgView = new ImageView(context);
        imgView.setLayoutParams(new Gallery.LayoutParams(150, 100));
        imgView.setScaleType(ImageView.ScaleType.FIT_XY);
    } else {
        imgView = convertView;
    }

    imageLoader.DisplayImage(data[position], activity, imgView);

    return imgView;
}

Try this:

public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imgView;
    if (convertView == null) {
        imgView = new ImageView(context);
        imgView.setLayoutParams(new Gallery.LayoutParams(150, 100));
        imgView.setScaleType(ImageView.ScaleType.FIT_XY);
    } else {
        imgView = convertView;
    }

    imageLoader.DisplayImage(data[position], activity, imgView);

    return imgView;
}
