使用SimpleAdapter 适配器时显示网络上图片方法

 SimpleAdapter listItemAdapter = new SimpleAdapter(this, listItem,
    R.layout.items_list,
    new String[] { "imagePath", "name", "njname", "length", "id" },
    new int[] { R.id.imagePath, R.id.name, R.id.njname, R.id.length, R.id.hiddenId });

第一步：设置listItemAdapter
  listItemAdapter.setViewBinder(new CustomViewBinder());

 

第二步：

import android.graphics.Bitmap;
import android.view.View;
import android.widget.ImageView;
import android.widget.SimpleAdapter.ViewBinder;

public class CustomViewBinder implements ViewBinder {
 public boolean setViewValue(View view, Object data, String textRepresentation) {
  if ((view instanceof ImageView) & (data instanceof Bitmap)) {
   ImageView iv = (ImageView) view;
   Bitmap bm = (Bitmap) data;
   iv.setImageBitmap(bm);
   return true;
  }
  return false;
 }
}
