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 });

listItemAdapter.setViewBinder(new CustomViewBinder());

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;
}
}
