你好,我用这个从sd卡加载图像。一切都很顺利,只是我想颠倒一下单子的顺序。我知道这是相当模糊,但希望有人可能会遇到这个适配器,可以帮助我。https://github.com/thest1/lazylist/tree/master/src/com/fedorvlasov/lazylist

import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
public class LazyAdapter extends BaseAdapter {
private final String[] data;
private static LayoutInflater inflater = null;
public ImageLoader imageLoader;
public LazyAdapter(Activity a, String[] d) {
// Declare variables
data = d;
inflater = (LayoutInflater) a
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
imageLoader = new ImageLoader();
}
public int getCount() {
return data.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
@SuppressLint("InflateParams")
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.gridview_item, null);
// Locate the ImageView in item.xml
ImageView image = vi.findViewById(R.id.image);
// Capture position and set to the ImageView
imageLoader.DisplayImage(data[position], image);
return vi;
}
}

为什么不使用回收视图和滑翔?这个图书馆已经过时了。要反转列表中的顺序,应将包含数据的列表按相反顺序传递给适配器。请检查以下示例:如何在java中反转int数组?
